Hydraulic brake(Normally closed, shaft mounted)The brake controls the braking and separation of the power shaft through oil pressure, pressure relief braking, and pressure boosting separationIt can be used in both dry oil-free and wet oil-immersed environmentsWith manual release function, the friction plate can be manually released during pressure reliefMulti friction plate structure, long service lifeExcellent torque holding function and high safetyThe brake is composed of a magnetic yoke, excitation coil, spring, brake disc, armature, spline sleeve, installation screws, etc. The brake is installed at the rear end of the flange plate (or motor) of the equipment; The transmission shaft is connected to the spline sleeve and the brake disc.When the excitation coil of the brake is connected to the rated voltage (DC), the electromagnetic force pulls on the armature to separate (release) the armature from the brake disc. At this time, the transmission shaft runs or starts normally with the brake disc. When the transmission system is separated or powered off, the brake is also powered off at the same time. At this time, the spring is applied to the armature, forcing the brake disc to produce Friction torque between the armature and the flange, so that the transmission shaft stops quickly. When the heat dissipation environment of the brake is poor and the transmission shaft operates continuously for a long time, if conditions permit, the voltage can be maintained to convert to 70% -80% of the rated voltage after the brake operates to reduce heating.Brake specifications: YZA1-315/23/model: Y 2 sets 2 brake specifications: YZA1-400/80/model: Y 2 sets 3 brake assembly specifications: YZA1-400/121/model: Y 1 set 4 brake assembly electric hydraulic brake specifications: YZA1-300/80/model: YAutomatic compensation brake specification: YZA1-400/121B/model: Y 6 sets 4 Automatic compensation brake specifications: YZA1-500/121B/model: Y 2 sets 5 brake specifications: YZA1-315/23/model: YYWZ9 series electric hydraulic block brake:YW160-E23 electric hydraulic drum brake shoeElectric hydraulic 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; YWZ9-800/301/12

The caliper disc brake can be divided into fixed caliper disc type and floating caliper disc type according to the structural type of the brake caliper.Caliper disc brakeThe brake disc is fixed to the wheel hub, and the brake caliper 5 is fixed to the axle, which cannot rotate or move axially along the brake disc. The brake caliper is equipped with two brake wheel cylinder pistons 2, which press against the brake pads on both sides of the brake disc. When the driver steps down the brake pedal to brake the car, the brake fluid from the brake master cylinder is pressed into the brake wheel cylinder, the hydraulic pressure of the brake wheel cylinder rises, the pistons of the two wheel cylinders move to the brake disc under the hydraulic pressure, press the brake block against the brake disc, and the brake block clamps the brake disc to generate Friction torque to prevent the wheel from rotating, so as to achieve braking.The brake caliper of caliper disc brake is floating and can move axially relative to the brake disc. Figure 3 shows the structure diagram of floating caliper disc brake. one thousand five hundred and forty-five trillion and ninety-seven billion eight hundred and thirty-two million three hundred and eighty-six thousand five hundred and twentySpecific production model: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 brakesDCPZ250, DCPZ300, DCPZ400 series electromagnetic caliper disc brakeYPZ2, YPZ3, YPZ1, YP series arm disc brakeSPZ symmetrical brake arm disc brakeSBD, SB series safety disc brakeSH, ST series hydraulic failure protection caliper disc 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 brakeThe brake caliper is generally designed to move axially relative to the brake disc. There is a hydraulic oil cylinder on the inner side of the brake disc, and a fixed brake block on the outer side is attached to the caliper body. When braking, the brake fluid is pressed into the oil cylinder, and under hydraulic pressure, the piston moves to the left, pushing the movable brake pad to move to the left and press against the brake disc. Therefore, the brake disc gives the piston a reaction force to the right, causing the piston and brake caliper body to move to the right along the guide pin 2, until the fixed brake pad 5 on the left side of the brake disc is also pressed onto the brake disc. At this time, the brake pads on both sides are pressed on the brake disc, and the brake pads clamp the brake disc to generate Friction torque that prevents the wheels from rotating, so as to achieve braking.Compared with the disk brake, the heat dissipation of the drum brake is much worse. The stability of the brake force of the drum brake is poor. The brake force varies greatly on different roads, and it is not easy to control. Due to poor heat dissipation performance, a large amount of heat will accumulate during the braking process. The brake pads and wheel drums are prone to extremely complex deformation under the influence of high temperatures, which can lead to brake decay and vibration, leading to a decrease in braking efficiency. In addition, after using the drum brake for a period of time, it is necessary to regularly adjust the gap between the brake shoes, and even remove the entire brake drum to clean the accumulated brake powder. Of course, drum brakes are not useless either. They are cheap in cost, have high braking force, and conform to traditional design. During the braking process of a four-wheel sedan, due to inertia, the load on the front wheels usually accounts for 70% -80% of the total load of the car. The braking force on the front wheels is greater than that on the rear wheels, and the rear wheels play an auxiliary braking role. Therefore, in order to save costs, car manufacturers adopt a braking method of front disc and rear drum. However, for heavy vehicles, because the speed is generally not very high, the durability of brake shoes is also higher than that of disc brakes, and the braking force is large, many heavy vehicles still use the four-wheel drum design today

The safe operation of the elevator is closely related to the working condition of the brake. A large number of accident cases have shown that one of the main reasons for elevator personal injury accidents is the failure of the brake or the existence of design defects, which leads to phenomena such as top punching, bottom sliding, sliding, and shearing of the elevator. Therefore, it is particularly important to strengthen the safety inspection of elevator brakes1. Common problems, safety requirements, and inspections of the mechanical part of the brake1.1 Common problems with the mechanical part of the brakeThe common problems with the mechanical part of elevator brakes are as follows.(1) The stroke indicator collides with the movable indicator, and some manufacturers' designers lack thoughtful consideration for the installation of the stroke indicator.(2) Long term use causes the brake shoe to fall off and the adhesive to loosen (some brakes are bonded rather than riveted).(3) The sealing rubber has aged and broken, causing foreign objects to fall into it, causing the brake to jam.(4) The electromagnet core rusts, causing the brake to jam.(5) The design of the elevator iron core guide mechanism is unreasonable, and multiple fractures occurred at the connection between the copper rod and the iron core, resulting in brake jamming.(6) Elevator maintenance personnel have improper methods for inspecting and maintaining brakes.

All seals and bearings of the Ed series electric hydraulic thrusters are imported products, with reliable sealing and long service life;Usage conditionsContinuous operation S1, continuous operation S2, load duration FC=60%Rated voltage is 380V three-phase, frequency 50HzThe altitude level of the location of use complies with the GB755-87 standardThe ambient temperature should be within the range of -20 ℃ to 40 ℃, and the relative humidity of the air should not exceed 90%Environmental temperature: -20 ℃~+50 ℃, using DB-25 hydraulic oil: BED electric hydraulic thruster holding brake, coal mine crane aluminum tankThe electric hydraulic thruster is composed of components such as rotor 1, stator 2, blades 3, oil distribution plate, and end cover; The inner surface of the stator is a cylindrical hole; There is eccentricity between the rotor and stator; The blades can slide flexibly in the slots of the rotor. Under the centrifugal force during rotor rotation and the pressure oil flowing into the blade root, the top of the blades is tightly attached to the inner surface of the stator, forming sealed working cavities between two adjacent blades, oil distribution plates, stator, and rotor; When the rotor rotates in a counterclockwise direction, the blade on the right side of the figure extends outward, and the volume of the sealing working chamber gradually increases, creating a vacuum. Therefore, oil is sucked in through the suction port 6 and the window on the oil distribution plate 5; On the left side of the figure; The blades retract inward, and the volume of the sealing chamber gradually decreases. The oil in the sealing chamber is pressed out through another window of the oil distribution plate and the oil pressure port 1 and output to the system; This type of pump absorbs and presses oil once during each rotation of the rotor, hence it is called a single acting pump; The rotor is subjected to radial hydraulic imbalance force, so it is also known as a non balanced pump, and its bearing load is relatively large; By changing the eccentricity between the stator and rotor, the displacement of the pump can be changed, so these pumps are variable displacement pumps.ED electric hydraulic thruster BED30 explosion-proof mesh diagram

Understand the hydraulic brake systemThe hydraulic brake is usually a locked motor with a brake wheel. It is a three-phase 380V small motor. When the motor needs to work, it can be connected in parallel with the motor through a contactor. If it is not a starting motor or a variable frequency motor, the working power can be connected to the motor to supply power to the brake motor. The motor rotates to drive the impeller, which uses hydraulic oil to push the hydraulic rod and open the brake. The holding brake is usually used in a constant holding state and only releases when powered on, so the electric control is generally simple. As long as the power supply of the thruster is connected in parallel with the power supply of the motor, the adjustment, maintenance, and use of the brake are carried out. Each traction machine is equipped with two brakes. When one brake fails to function for some reason, the other brake still has sufficient braking capacity1. Adjust the nut and adjust its position to control the armature inside the brake body to always be in a suitable position, maintain a reasonable working stroke, and avoid hitting the armature and manual opening cam during closing, causing noise;4- Control the stroke of the brake opening force, and under the condition of large opening clearance, control the stroke of the brake arm and the working clearance between the brake shoe and the brake wheel; 5- Compress the spring and adjust its compression star to control the size of the braking force. Excessive compression can cause difficulty in opening the brake body; 7- Compress the nut and adjust its position to control the magnitude of the braking force;9- Top rod screw, controlling the degree of fit between the brake shoe and the brake wheel (the better the fit between the brake shoe and the brake wheel, the greater the braking force formed under relative conditions, and the lower the working noise); Specific production model: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 brake 6 types of brakes13- Pull rod, which determines the formation of braking force and controls the large opening gap;2. 3, 8, 10- Lock nuts to prevent loosening of each adjustment screw after system action after adjustment is completed, which may cause system changes; 17 scale is just a reference mark for the system to restore the original braking force. Preparation before adjusting the brake: 1. Switch the elevator to maintenance mode2. To_ Open the lift car up to allow the counterweight to fall on the support3. Check the transformer voltage of the braking circuit to ensure that the AC voltage meets the schematic requirements. 4. Check and confirm that the safety circuit is effective. 5. Cut off the main power supply and execute the locking procedure6. Press the emergency stop switch and/or other emergency stop switches of the control cabinet 7. Remove the machine protective cover 8. Clean the main unit9. Check and ensure that the brake arm and all other moving parts are not rusted, and all moving parts must be able to move and rotate freely. If necessary, disassemble the brake and thoroughly clean and lubricate it. Reassemble the brake in its original state after disassembly.Attention: The locking procedure must be strictly followed. Before starting the brake adjustment work, ensure that there is no electrical or mechanical energy present. Ensure that the brake hub and brake shoes are not contaminated with grease and lubricants.Adjustment of brake opening stroke: refer to Figure 11, loosen nut 3 and screw 4.2. The top rod 4 must completely leave the screw 14 of the brake core.3. Rotate screw 4 clockwise until it is in contact with top rod screw 14, then continue to rotate clockwise for 1 turn (pitch 2mm) to push the brake top rod and move the armature inward by 2mm. Adjust the other side using the same method.4. Power on the brake, and at this time, the large stroke of the brake top rod moving outward from the inside is 4mm. If the stroke is small, rotate the top rod screw 4 clockwise to increase the stroke; otherwise, decrease the stroke counterclockwise. Tighten nut 3 afterwards. Observe whether there is a sound of the armature hitting the end cover when opening the brake. It is advisable to ensure that the armature does not hit the end cover and that the gap is small.5. If there is a sound of impact, rotating nut 1 counterclockwise can increase the stroke of the iron core, while rotating nut 1 clockwise can shorten the stroke of the iron core. Attention: Observe whether the brake switch of the brake can be fully closed and opened, otherwise adjust the corresponding top rod screw.

Insufficient braking force issueWhen the braking force of the disc brake is insufficient, the following methods can be used to solve the problem:1. Change the brake pad materialA slightly softer brake pad material can be used to improve the friction coefficient and increase the braking force.2. Remove foreign objects from the debris removal groove of the brake padIf the debris discharge groove of the brake pad is covered by foreign objects, the effect of dust discharge and water scraping will be lost during braking, resulting in a decrease in braking force.3、 Noise during brakingWhen braking, if there is a "squeaking, squeaking" noise, the following methods can be used to eliminate it:1. Add an anti noise pad between the brake caliper piston and the brake lining to create a tilt on the piston. This ensures flexible contact between the brake pads and brake discs during braking, ensuring that there is no abnormal noise in the brake pads under normal wear and tear conditions.2. Choose a brake pad material that is softer and less dense.3. When braking, the brake pads may move to one side and there may be a knocking sound. This is due to the excessive gap between the brake pad and the caliper body, which can be eliminated by electroplating solder. However, it should be noted that the solder should be coated on the side opposite to the direction of travel to prevent failure under the action of braking force.SBD brake installation siteElectromagnetic failure protection disc brake:3SE; 4SE; 5SE; 450SE; 56SE; 560SE; 561SE; ST1SE; ST2SEHydraulic fail safe disc brake:3SH; 4SH; 5SH; 450SH; ST1SH; ST2SH; ST3SH; ST4SH; ST5SH; ST10SH; ST16SH; ST25SH; 904SH;ST40SHPneumatic fail safe disc brake:3SP; 4SP; 5SP; 450SPHydraulic direct acting disc brake:ADH60; ADH90; ADH120; DADH75; DADH80; DADH90; DADH120; DADH195; DADH350Pneumatic direct acting disc brake:ADP60M; ADP61M; ADP62MPneumatic caliper disc brakeCQPL12.7A-A; CQPL12.7A-B; CQPL12.7B; QPL12.7A-A; QPL12.7A-B; QPL12.7-A; QPL12.7-B;QP30-D; QP25.4-D; CQP30-D; CQP25.4-D; PDA5; PDA10; PDB5; PDB10; PDB19; PDC5; PDC10Electromagnetic caliper disc brake:DCPZ12.7-250; DCPZ12.7-300; DCPZ12.7-400Hydraulic caliper disc brake:SB (YQP) 50; SB (YQP) 100; SB (YQP) 160; SB (YQP) 250; SB (YQP) 315; SB (YQP) 400;SBD safety brake:SBD100-A; SBD125-A; SBD160-A; SBD200-A; SBD250-A; SBD-B; SBD160-B; SBD250-C; SBD365-C; SBD425-C; SBD80-B; SBD160-B; SBD250-C; SBD365-C; SBD425-C; SBD120-D; SBD240-DThere are two types of brake linings for disc brakes: one is that the brake band is made of asbestos rubber steel wire mesh, the other is that the brake pad is made of asbestos resin, and the non asbestos brake pad and brake pad are of clip in type and riveted type, which are safe, reliable, easy and fast to replace.Its characteristics are:1.
