Regularly check the length of the armature stroke. Because during the operation of the brake, the travel length of the armature will increase due to wear on the moving surface. When the length of the armature stroke cannot reach the normal value, it is necessary to adjust it to reproduce the small gap between the moving surface and the turntable. If the stroke length of the armature increases above the normal value, it may greatly reduce the suction force. If the worn brake surface is replaced, the small gap between the brake surface and the rotary table should be adjusted appropriately from the beginningYWZ5-630/301 is widely used for deceleration and parking braking of mechanical drive devices in lifting, metallurgy, mining, ports, docks, construction, and other fields..

Some drum brakes have an inspection hole on the back that allows you to see how much material is left on the brake shoes. When the friction material has worn to the point where the rivet is only 0.8 millimeters long, the brake shoes should be replaced. If the friction material is bonded to the rear base plate (not with rivets), the brake shoes should be replaced when the remaining friction material is only 1.6 millimeters thickHenan Jiaozuo Brake Co., Ltd. is a comprehensive manufacturer that integrates research, development, manufacturing, and service of various series of brakes and their supporting driving devices.

Product Introduction:BYT1 series flameproof electric hydraulic thruster is a compact drive control device integrating motor, centrifugal pump and oil cylinder. It is widely used as the drive device of various block brakes and disc brakes, and can also be used for the drive control of various industrial valves, gates, directional swing and rotation (<90 °) devices and clamping devices. When the power is cut off, the impeller stops rotating, and the piston rapidly descends under the force of the load spring and its own gravity, forcing oil to flow back into the upper part of the piston. At this time, it still returns to its original position through the lever mechanism. Compliant with standards:The BYT1 series explosion-proof electric hydraulic thrusters have an insulation level of B and an enclosure protection level of IP54.The altitude of the location of use complies with GB755-2000;Outdoor rain and snow erosion or corrosive gases and media should use anti-corrosion products.BYT1 series explosion-proof electric hydraulic thruster:BYT1-18ZB/2; BYT1-25ZB/4; BYT1-25ZC/4; BYT1-45Z/4; BYT1-45Z/5; BYT1-45Z/6; BYT1-90Z/6BYT1-90Z/8; BYT1-125Z/10; BYT1-180Z/8; BYT1-180Z/10; BYT1-180Z/12; BYT1-320Z/12 BYT1-320Z/20; BYT1-25/4; BYT1-45/6; BYT1-90/8; BYT1-180/12BED ZED series electric hydraulic thrusters:BED30/5; BED50/6; BED80/6; BED121/6; BED201/6; BED301/6; BED50/12; BED80/12; BED121/12 BED201/12; BED301/12; BED630/12Explosion proof BYT1-45Specific production model:YT1, ED, YTD.BYT1, BED, ED2, MYT1, ZED, DEd series electric hydraulic thrustersYWZ, YWZ3, YWZ4, YWZ5, YWZ8, YWZ10, YWZ9, YWZ13, YW, YWL series electric hydraulic brakesYT1 series electric hydraulic thrusters: YT1-18Z/2, YT1-18ZB/2, YT1-25Z/4, YT1-25ZB/4, YT1-45Z/4, YT1-45Z/5, YT1-45Z/6, YT1-90Z/6, YT1-90Z/8, YT1-125Z/10, YT1-180Z/8, YT1-180Z/10, YT1-180Z/12, YT1-320Z/12, YT1-320Z/20, YT1-25/4, YT1-45/6, YT1-90/9-8, YT1-125/10.

However, if encountering complex weather conditions, unstable wind power levels or inability to accurately predict, in order to ensure safety, the main engine must stop running, which greatly affects work efficiency; And once encountering unpredictable strong gusts during normal operation, operators have no emergency time and are prone to serious accidents such as overturning or equipment falling into the sea. This not only causes losses to production, but also threatens the safety of operators.Rail clamps and anti climbing devices (rail supports) are dynamic wind protection devices that can play a dynamic wind protection role in the working state of the main equipment and an auxiliary wind protection role in non working state. Due to the inability of operators to respond in a timely manner and even to make incorrect reactions in unexpected situations, the operation of the rail clamp should be an automatic control process. The rail clamp is interlocked with the host equipment. When there is a power outage or the measured wind speed exceeds the limited range, the rail clamp will receive a signal to automatically clamp the track, which can effectively respond to sudden situations.According to actual needs, the rail clamp has been divided into multiple levels according to the magnitude of anti slip force. The user should refer to data such as the windward area of the crane and on-site wind load during the equipment design stage to select a suitable model.

Knowledge of matching composition principle of disc brake and brake discThe disc brake is mainly used with the brake disc to form a disc brake device, which is used for working braking and emergency safety braking of large electromechanical equipment to achieve controllable braking and parking. Due to its normally closed structure, it also has a seating function.Disc brake series (commonly known as holding brake, installed on both sides of the brake disc of the winch drum, friction brake disc forces the drum to stop when braking), disc brake is a hydraulic actuator applied to the braking system of the mine hoist, and its exact name should be: normally closed rear cylinder disc brake. At present, rear cylinder is widely used. When the hoist starts, the hydraulic station outputs pressure oil to open the brake, and the hoist starts to work, During the working braking, the hydraulic station will increase or decrease the pressure according to the working condition, and the disc brake will provide the opposite braking force. Under the accident condition, the pressure of the hydraulic station will return to the residual pressure, and the brake will stop the hoist in a short time with a large braking force.2、 Installation requirements1) The two large planes of the brake shoe should be scraped flat, assembled according to its assembly drawing, and the brake shoe and sliding sleeve should be fully fitted to ensure uniform pressure between the brake shoe and the brake disc.2) The oil pipe, disc brake cylinder, oil passage, piston, etc. of the disc brake shall be clean, and the surface shall be free of bruises, etc.3) Check the end face deflection of the brake disc, and its value should not exceed the actual drawing requirements.4) The deviation H between the two sides of the support of the same disc brake and the brake surface of the brake disc shall not be greater than, and the non parallelism between the two sides of the brake support and the brake surface shall not be greater than5) The symmetrical centerline plane of the brake cylinder of each disc brake and the axis of the main shaft shall be in the same horizontal plane, and the deviation 2 shall not be greater than 3mm.Structure principle of disc brakeThe fixed component is installed on the fixed component, and the brake disc is connected to the rotating component. When braking, the fixed component is pressed onto the brake disc, utilizing friction to achieve braking.structure type The structure of fixed components in massage wipes can be divided into two types: clamp disc type and full disc type1. The structural principle of the full disc brake: the rotating elements and fixed elements of the friction pair in the full disc brake are both disc shaped. When braking, the friction surfaces of the two discs are in full contact, and the working principle is like a friction clutch.2. The structure principle of the caliper disc brake: the fixed element of the caliper disc brake is the brake pad, which is installed in the brake caliper that is connected with the axle and cannot rotate around the axle axis. The contact area between the brake pad and the brake disc is very small.classificationFixed clamp typeStructural features: The brake caliper does not move, and there are hydraulic cylinders on both sides of the brake discPerformance characteristics: There are no sliding parts except for pistons and brake pads, with good stiffness and easy manufacturing. It can adapt to different circuit driving requirements, but it is large in size, difficult to arrange, and generates a lot of heatSliding clamp typeStructural features: The brake caliper can perform axial sliding, and there is a hydraulic cylinder on the inner side of the brake discSwing clamp typeStructural features: The brake caliper is hinged with the fixed seat, and there is a hydraulic cylinder on the inner side of the brake discST3SH Double On Off Real ImageSpecific production model of brake:YT1, ED, YTD.BYT1, BED, ED2, MYT1, ZED, DEd series electric hydraulic thrustersJZ, MW, TJ2, ZWZA, ZWZ3 series electromagnetic brakesYWZ, YWZ3, YWZ4, YWZ5, YWZ8, YWZ10, YWZ9, YWZ13, YW, YWL series electric hydraulic brakesBYWZ, BYWZ3, BYWZ4, BYWZ5, BYWZ8, BYWZ10, BYWZ9, BYWZ13, BYW series electric hydraulic brakesQP, CQP, QPC, CQPL, QPL, PDA series pneumatic caliper disc brakeDCPZ250, DCPZ300, DCPZ400 series electromagnetic caliper disc brakeYPZ2, YPZ3, YPZ1, YP series arm disc brakeSPZ symmetrical brake arm disc brakeSBD, SB series safety brakesSH, ST series hydraulic failure protection brakeDADH, ADH, ADP series hydraulic direct acting brakesSE series electromagnetic failure protection brakeSP series pneumatic failure protection brakeYFX, YDGZ, YLBZ, Series Windproof Wedge BrakesYQP hydraulic disc brakeElectric hydraulic arm disc brake series model:YPZ2IV, V, VI electric hydraulic arm disc brakes, YPZ2I, YPZ2II, YPZ2III electric hydraulic arm disc brakes.Pneumatic caliper disc brake series model:DCPZ12.7 series electromagnetic caliper disc brake, CQPL12.7-B pneumatic caliper disc brake, CQPL12.7-A direct pneumatic caliper disc brake, CQP12.7 pneumatic direct caliper disc brake, QPL12.7-A pneumatic caliper disc brake, QP12.7-A pneumatic caliper disc brake, QP12.7 pneumatic caliper disc brake, DJPZ motor disc brake.Electric failure protection brake series model:ST1SH hydraulic failure protection brake, ST2SH hydraulic failure protection brake, ST3SH hydraulic failure protection brake, ST4SH hydraulic failure protection brake, ST5SH hydraulic failure protection brake, SBD hydraulic failure protection brake, 561SE electric failure protection brake.Electric hydraulic windproof iron wedge brake series model:DFX, DAF electromagnetic hydraulic safety windproof iron wedge brake, YFX (YAF) series electric hydraulic windproof iron wedge brake.characteristic1.

Use a dial gauge to detect that the cross-sectional runout error of the brake disc is greater than 0.06mm. The surface of the brake disc has obvious wear steps and strained grooves, which can be processed and repaired2. Check that the wear limit thickness of the brake disc is 8mm. If the thickness exceeds the limit, replace it with a new oneWhen the thickness of the brake shoe friction plate is less than 7mm (including the bottom plate), the friction plate must be replaced, and the left and right wheels must be replaced in sets (4 friction plates, 4 spring plates)4. Check the brake caliper body. If any oil leakage is found, replace it with a new piston sealing ringIn the case of full contact between the brake shoe and the brake disc, the actual average friction radius R shall not be less than the designed average friction radius R.The gap C between the brake production and the outer edge of the brake disc shall not be less than 5 millimeters.

Slipping inspection for insufficient braking force of the hydraulic brake of the craneCheck the safety of the hydraulic brake of the crane to see if the entire brake is smooth during operation, and then check if the contact of the brake electromagnet core is good. During the electromagnetic inspection process, a wrench can be used to piezoelectric the magnetic core to check if it is flexible enough; Shake the brake arm mainly to observe whether there are wear issues in the details of the brake arm, and regularly repair and replace the brake arm (the brake arm is the main wear area); Check the dynamic and static iron cores of the long-term brake using the cement layer exclusion method (implemented at the bottom of the brake), or special cement can be used to increase the firmness. 1. The brakes of each mechanism should be regularly checked and adjusted for the clearance between the brake pads and brake wheels to ensure flexibility and reliability. There should be no dirt on the friction surface, and any dirt must be washed off with gasoline or thinner2. The lubrication and hydraulic oil of various parts such as the gearbox, gearbox, and external meshing gear shall be carried out according to the requirements in the lubrication table3. Pay attention to checking each part of the steel wire rope for broken wires and loose strands. If it exceeds relevant regulations, it must be replaced immediately. The maintenance and upkeep of the steel wire rope should strictly follow the provisions of GB5144-854. Regularly check the connection of each part, and tighten it if there is any looseness. The tightness of the connecting bolts of the engine body should be checked when the engine body is under pressure (the method of rotating the arm can be used to cause compression). All connecting shafts must have split pins and be fully opened Two types of diagrams, YWZ4 and YWZ5. Regularly check whether each mechanism operates normally and whether there is noise. If any fault is found, it must be eliminated in timeWhen installing, disassembling, and adjusting the rotating mechanism, it is important to ensure that the centerline of the reducer of the rotating mechanism is parallel to the centerline of the gear, and its meshing surface is not less than 70%. The meshing clearance should be suitable7. Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely mannerBrake troubleshootingDue to the complex internal structure of the brake, it may cause malfunction problems during long-term use. Therefore, it is necessary to troubleshoot the brake and adopt corresponding maintenance methods or replacement to ensure the performance of the crane in actual use.4.1 Insufficient braking force issueIn the daily production of cranes, there is a high possibility of insufficient braking force. As the final performance of the entire brake system is braking force, comprehensive investigation is necessary. Based on years of work experience, it can be concluded that the main factor causing insufficient braking force is the issue of brake wheels. It is necessary to focus on detecting the wear of the brake wheels, as severe wear or loose springs can cause insufficient braking force. At the same time, if there are too many stains or insufficient lubrication on the brake wheels, it will also reduce the braking force of the brake. Due to the direct impact of brake wheels on the safety of crane operation, troubleshooting work must be taken seriously.

Crane safety disk brake performance knowledge referenceThe safety disc brake to be added here refers to adding brake discs on the drum and placing array disc brakes at appropriate positions with reference to the brake settings of the vertical Boat lift, so that they become a completely independent safety braking system. The advantages of doing so are obvious.(1) Freed the manual operation of guardians and reduced the risk of injury;(2) Enhanced the safety and reliability of crane operation, effectively preventing the expansion of accidents in the event of crane accidents. Simply put, if a crane experiences a gear shift or hook slip accident, even in the event of damage to the starting motor, transmission shaft, working brake, and gearbox, the safety brake of the drum can effectively close and brake, preventing the hook from continuing to slide and preventing the accident from further expanding;(3) On some special Overhead crane that need to be mechanically switched between high and low speed gears by the gearbox,The disc brake has the following advantages:1) The disc brake has no friction potential, so the brake efficiency is less affected by the friction coefficient, that is, the brake efficiency is stable;2) In the disc brake, the unit pressure of the friction block to the brake disc is relatively high, which is easy to squeeze water out. After the wheels wade into water, the change in braking efficiency is relatively small, and due to the centrifugal force and the friction effect of the pads on the brake disc, only one or two brake applications are needed after the water is released, and the performance can be restored.3) When the output braking torque is the same, the size and mass are smaller.SBD and ST3SH imagesThe thermal expansion of the brake disc along the thickness direction is extremely small, and it will not significantly increase the brake clearance like the thermal expansion of the brake drum, resulting in excessive brake pedal travel. Easy to achieve automatic clearance adjustment, and other maintenance and repair operations are also relatively simple. In addition to the advantages of the above braking performance, the disc brake has the characteristics of low noise and low vibration in use, which improves the riding comfort., Just turn on the safety brake and brake it, ensure that the drum is tightly held by the safety brake, and take corresponding measures to prevent the safety brake from mistakenly operating. You can then release the working brake as needed to switch between high and low gears. Brake Fundamentals Training - Brake Fundamentals Training defines the mechanism that generates forces that prevent the movement or tendency of a vehicle. The function is to reduce or stop the speed of vehicles in motion. Brake knowledge. PDF, Brake knowledge 1. Purpose and scope of application are mainly used in heavy industrial fields such as metallurgy, mining, building materials, electricity, machine manufacturing, and transportation fields such as ports and railway loading and unloading. It can slow down or even stop cars in motion, keep the speed of cars traveling downhill stable, and keep stopped cars stationary, These actions are collectively referred to as braking; A series of specialized devices installed on a car so that the driver can apply a certain amount of force (mainly on the road surface) to certain parts of the car (mainly on the wheels) based on road and traffic conditions, to brake the car to a certain extent. This controllable external force for braking the car is called braking force; This series of specialized devices is called a braking system. The braking system used to slow down or even stop a moving car is called the service braking system; A device used to keep a stopped car stationary is called a parking brake system. These two brake systems are mandatory for every car. At present, the vast majority of crane brakes are hub type brakes. When it is necessary to open or brake, the force of the brake spring is compressed or released by electromagnetic suction, discharge, or oil pump starting or stopping, so that the brake shoe leaves the brake wheel or is clamped onto the brake wheel, achieving the requirements of opening or braking. Nowadays, in lifting work, especially when lifting large heavy objects, several staff members responsible for monitoring are often equipped on the crane. The purpose is to use tools such as crowbars to increase the pressure on the brake shoes on the brake wheels in case of derailment or hook slipping accidents during lifting, in order to achieve emergency braking and reduce the degree of damage caused by the accident. The safety brake is set as a normally open safety brake, which always remains fully open. The braking work for crane lifting is completed by the working brake, which serves as a backup for protection. The safety brake is only put into use when the crane malfunctions or accidents occur, or when the service brake needs to be repaired and the service brake needs to be released to switch between high and low gears

Knowledge of the structural principles of electric hydraulic drum brakesThe electric drum pressure block brake device generates friction between the brake pads and the wheel drum or disc, and during the friction process, the kinetic energy of the car during driving is converted into thermal energy for consumption. There are two common types of brake devices: "drum brake" and "disc brake", and their basic features are as follows:Drum brake: Install two semi circular brake pads inside the wheel hub of the car, and use the "lever principle" to push the brake pads to make them come into contact with the inner surface of the wheel drum and cause friction. According to the connection method between the brake pad (referred to as the brake pad) and the brake pad, the hydraulic brake and whether there is a counterbore at the end of the brake pad hinge hole are divided into the following 5 types: B1 type: hydraulic brake requires rivet holes on the brake pad, and the brake pad is connected by bonding, and the end of the brake pad hinge hole is not counterbore; B1C type: without rivet holes on the brake pad, connected to the pad by bonding, and the end of the brake pad hinge hole has a countersunk hole; B2 type: There are rivet holes on the brake pad, which are used to bond and connect the brake pad. The end of the brake pad hinge also has no countersunk holes; B2C type: There are rivet holes on the brake pads, which are connected to the brake pads by riveting. The end of the brake pad hinge shaft also has a countersunk hole. ZK type: brake pad mounting type YWZ4 red net diagramDrum brakes have been used in cars for nearly a century, but due to their reliability and powerful braking force, drum brakes are still used in many car models (mostly on the rear wheels). Drum brake is a hydraulic device that pushes the brake pads inside the brake drum outward, causing friction between the brake pads and the inner surface of the brake drum that rotates with the wheels, resulting in braking effectThe inner surface of the drum brake drum is the location where the braking device generates braking torque. Under the condition of obtaining the same braking torque, the diameter of the brake drum of the drum brake device can be much smaller than that of the brake disc of the disc brake. Therefore, large vehicles used for carrying loads can only install drum brakes in the limited space of the wheels to obtain strong braking force.Mode of action of drum brakeSimply put, drum brake is a braking device that uses the stationary brake pads inside the brake drum to friction the brake drum as the wheels rotate, in order to generate friction and reduce the speed of wheel rotation.When pressing the brake pedal, the force exerted by the foot will cause the piston in the brake master cylinder to push the brake oil forward and generate pressure in the oil circuit. Pressure is transmitted to the brake cylinder piston of each wheel through brake oil, which then pushes the brake pads outward, causing friction between the brake pads and the inner surface of the brake drum, and generating enough friction to reduce the wheel speed to achieve the purpose of braking.The action mode of the disc brake:As the name suggests, disc brakes use stationary brake discs to grip the brake discs that rotate with the tires to generate friction, causing the wheels to rotate at a lower speed.When the brake pedal is pressed, the piston in the brake master cylinder is pushed and pressure is established in the brake oil circuit. Pressure is transmitted to the piston of the brake cylinder on the brake caliper through brake oil. When the piston of the brake cylinder is under pressure, it moves outward and pushes the brake pads to clamp the brake disc, causing friction between the brake pads and the brake disc, reducing the wheel speed and slowing down or stopping the car.Hydraulic brakes have stable braking, low noise, long service life, and multiple power connections. The brake can automatically compensate for pad wear and does not require frequent maintenance and adjustment.

The technical personnel from the manufacturer of the belt mechanism actuator will provide you with a detailed introduction! Maintenance methods for brakes.1. The brake is easily infected with oil stains at the driving equipment. To avoid affecting the braking effect, the adjacent oil stains should be promptly sorted out.2. When cracks appear on the driving wheel of the belt mechanism and the thickness of the brake wheel flange reaches 40% of the original thickness, it should be discarded3. The gap between the brake and the brake wheel should be adjusted properly, and the brake shoe should not rub against the brake wheel. Regularly check the use of the friction plateThe composition and working principle of a tube belt conveyor. The general structure of a tube belt conveyor is basically the same as that of a regular conveyor, except that a circular tube shape is formed in the middle conveying section from the receiving point to the unloading point. That is, after the tail receiving section, the tape gradually transitions from parallel to groove or deep groove, and then wraps the material and rolls it into a circular tube shape. Belt conveyors can be used for both horizontal and inclined conveying of materials. When the average inclination angle of a belt conveyor that uses inclined conveying of materials is greater than four degrees, when the belt conveyor stops with full load, the belt will reverse when transporting materials up and the belt will slide when transporting materials down, causing accidents such as material accumulation and flying. To avoid this situation, manufacturers will add braking devices during production. Due to the fact that belt conveyors are mainly used in industries such as mining, grain, metallurgy, building materials, chemical, food, etc., and continuously conveying materials in the conveying industry, they also play a leading role in the production of the conveying industry. Therefore, the quality requirements for belt conveyors are also very strict, especially for large conveyors.YWZ5 Electric Hydraulic BrakeIn the forming section of the tube belt conveyor, the tape is forcibly wrapped into a circular tube by hexagonal rollers, and the conveying material is completely enclosed in the circular tube and runs stably with the tape, thus achieving the goal of environmental protection. When reaching the head (or middle discharge point), the tape gradually transitions from a circular tube to a deep groove or groove, and then discharges at the head drum (or middle discharge point). The return section of the belt conveyor belt is basically the same as the load-bearing section, generally forming a circular tube shape, and under certain conditions (through a flipping mechanism), it can achieve bidirectional transmission of ED electric hydraulic thrusters Ed23/5, Ed30/5, Ed50/6, Ed80/6, Ed121/6, Ed201/6, Ed23/5, Ed30/5, Ed50/6, Ed80/6, Ed121/6, Ed201/6, Ed301/6YWZ9 series electric hydraulic block brake: YWZ9-200/23; YWZ9-200/30; YWZ9-250/23; YWZ9-250/30; YWZ9-250/50; YWZ9-300/30; YWZ9-300/50; YWZ9-300/80; YWZ9-315/30; YWZ9-315/50; YWZ9-315/80; YWZ9-400/50; YWZ9-400/80; YWZ9-400/121; YWZ9-500/80; YWZ9-500/121; YWZ9-500/201; YWZ9-600/121; YWZ9-600/201; YWZ9-600/301; YWZ9-630/121; YWZ9-630/201; YWZ9-630/301; YWZ9-700/201; YWZ9-700/301; YWZ9-710/201; YWZ9-710/301; YWZ9-800/301/12YWz5 series hydraulic block brake:YWZ5-200/23, YWZ5-200/30, YWZ5-250/23, YWZ5-250/30, YWZ5-315/50, YWZ5-400/80, YWZ5-400/121, YWZ5-500/121, YWZ5-500/201, YWZ5-630/201, YWZ5-710/301, YWZ5-800/301There are various types of brakes for belt conveyors, and different forms of brakes can be selected based on the technical performance and specific usage conditions of the conveyor (such as power size, installation angle, etc.).
