The hydraulic brake is usually a locked motor with a brake wheel. It is a three-phase 380V small motor, and the YT1 thruster uses a contactor when the motor is about to work. If it is not a starting motor or a variable frequency motor, the working power can be connected in parallel with 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.Hydraulic holding brake, which provides a DC power supply to the holding brake coil when the motor is working. When there is current in the holding brake coil, an electromagnetic armature is generated to open the holding brake device. The holding brake is usually used in a constant holding state and only releases when powered on, so electrical control is generally simple. As long as the electromagnet power supply is connected in parallel with the motor power supply, the motor drives the rotor shaft and the impeller on the rotor shaft to rotate, generating pressure inside the piston. Under this pressure effect, oil is sucked from the upper part of the piston to the lower part of the piston, forcing the piston and the push rod and crossbeam fixed on it to quickly rise. By mechanically compressing the load spring through a lever (if the thruster or brake is equipped with a load spring), mechanical motion is generated.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.Electric hydraulic thrusters are often used in conjunction with brake frames and are widely used for braking various transmission devicesPerformance and structural characteristicsEd series electric hydraulic thrustersThe Ed series thrusters are produced and manufactured using a complete set of design and manufacturing technology from the original West German EMG company, in accordance with DIN 15430 and JB/T10603-2006 standards in Germanyaccurate The components of the Ed series thrusters are processed by CNC machining centers, from processing to assembly, with strict craftsmanship, complete testing, reliable performance, and lifespanThe experiment ensured the performance of the entire machine.The aluminum alloy shell is fully sealed with a single push rod structure, with beautiful appearance, light weight, complete functions, excellent performance, and complete variety and specifications.The motor is a non oil immersed structure with F-class insulation, good heat resistance, and long service life.The motor junction box cover is equipped with a seal and uses a cable stuffing box for incoming lines, which is firm and reliable.

It is widely used in industries such as lifting transportation, metallurgy, mining, port electric hydraulic block brake ports, and construction.Electric hydraulic thrusterWarning: The thruster should be reliably grounded according to electrical specifications! Attention: When wiring, cut off the power supply and erect a sign at the power switch that reads "Someone is working, do not switch on",Until the wiring is completed.When wiring, remove the connector box cover of the thruster (with wiring diagram on the back), and connect the three-phase power line (phase sequence not required) and grounding wire as required. Then cover the junction box cover and tighten the screws (see Figure 4). Note: The protection level of the thruster is IP65. The cable should enter the junction box through a stuffing box (the stuffing box needs to be provided by the user). There is a grounding screw inside and outside the junction box, and users can choose one grounding point as needed. The connection method (Y/△) of the motor stator winding has been completed before leaving the factory. Unless it is confirmed that the power supply does not match the connection method, do not change it arbitrarily.

The company, with its team, rigorous management, and advanced equipment, is committed to building itself into an enterprise in the brake and related product industry. Long range block brakes can generate large release force through the brake lever system, but the braking action is slow, making them suitable for large brakes.Here we will introduce the short running block brake.Short stroke block brakes have the advantages of quick action, small electromagnetic stroke, and smaller weight and overall dimensions, making them widely used in lifting and transportation machinery. Its disadvantages are high work impact, loud noise, and short electromagnetic lifespan. This type of brake requires a large amount of electromagnetic attraction. When the diameter of the brake wheel exceeds 300 millimeters, the size, weight, and electrical energy consumption of the electromagnetic sharply increase. Therefore, short stroke block brakes are generally suitable for small and medium-sized brakes with brake wheel diameters less than 300 millimeters.Structural characteristics1.

Operating principle of pneumatic caliper disc brake QP12.7-A QP25.4, QP30-D, CQP12.7, QP38, CQP40-D pneumatic caliper Disc brake frame and cylinder are composed of two parts. When cylinder 1 is filled with pressure air, piston rod 5 quickly contracts into the cylinder under the action of air pressure. The left and right brake arms, under the action of return spring 4, drive the friction block 12 to quickly open (i.e. release the brake). When the cylinder stops supplying air and quickly deflates through the control valve, the piston rod 5 quickly extends under the internal spring of the cylinder, pushing the left and right brake arms to drive the friction block 12 to close (i.e., the holding brake).2、 Installation of pneumatic caliper disc brake 1. First, check the brake surface of the brake disc and brake pad for oil sludge or other stains. 2. Install the G3/8 "(cast iron rod cylinder) or 1/2" (cast aluminum cylinder) connector on the air inlet of cylinder 1, connect the air pipe with a hose, and the air source should be free of oil, water, and other impurities 3. During installation, pressure air is first introduced to retract the piston rod 5 into the cylinder. Then, the friction block 12 is installed in the direction perpendicular to the brake disc, and the base 9 is fixed horizontally on the rigid base so that its center is in line with the thickness center of the brake disc. The installation position dimensions are shown in the structural diagram3、 Adjustment of pneumatic caliper disc brake a) Adjust the air pressure value, which is 5~7 bar. b) For normal work, the first step is to test the brake several times and check if there are any abnormalities in the brake. c) The retraction distance of the friction block can be adjusted by rotating the adjustment rod 6 to change the size of the working stroke. When rotating the adjustment rod, pressure air is first introduced to retract the piston rod, and then adjusted.4、 Maintenance of pneumatic caliper disc brake When the friction plate is worn and the working stroke increases to 8mm, it is necessary to immediately adjust rod 6 to readjust the working stroke to about 4mm, otherwise the brake will fail. After adjustment, tighten nut 7. When the friction block 12 is worn to about 6mm, replace the wear block. The replacement steps are as follows: 1. Cylinder, 2. Right brake arm 3. Reset spring 5. Piston rod 6. Adjustment rod 7. Nut 8 Left brake arm 9, base 10, brake block 11, spring steel wire 12, friction blockDCPZZ12.7 series air caliper disc brake manufacturer/SBD series disc brake price/Jiaozuo Brake Co., LtdThe disc brake has hydraulic type, which is controlled by hydraulic pressure. The important parts include brake disc, wheel cylinder, brake caliper, oil pipe, etc. The disc brake features fast heat dissipation, light weight, simple structure and convenient adjustment. In particular, under high load, it has good heat resistance, stable braking effect, and is not afraid of mud and water. When driving in winter and under bad road conditions, many car disc brakes have flat brake discs, perforated brake discs, and scoring brake discs. Among them, scoring brake discs have good braking effect and ventilation and heat dissipation capacity.The pneumatic disc brake applies force along the brake disc, the brake shaft is free from bending moment, and the radial dimension is small.Compared with the drum brake, the working surface of the disc brake is flat and heat transfer occurs on both sides. When the disc rotates, it is easy to cool and not easy to change significantly. The braking efficiency is relatively stable. After a long time of use, the brake disc has enhanced its braking effect due to high-temperature expansion; The drum brake has a single side heat transfer and a large temperature difference between the inside and outside, which makes the brake drum prone to deformation. At the same time, after prolonged braking, the brake drum expands due to high temperature, and the braking efficiency is weakened. In addition, the disc brake is simple in structure, convenient in maintenance, and easy to realize automatic adjustment of brake clearance.The disadvantage of the disc brake is that the friction plate acts directly on the disc, without automatic friction amplification, and the braking efficiency is low. If the brake actuating pipeline pressure is high when used in the hydraulic braking system, a power auxiliary device must be installed separately; When also used for parking brake, the added parking brake transmission device is more complex than the drum brake, so its application in the rear wheels is limited byElectromagnetic 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-DElectric hydraulic windproof iron wedge brake:YFX series electric hydraulic windproof iron wedge brake:YFX-500/80; YFX-550/80; YFX-600/80; YFX-630/80; YFX-700/80; YFX-710/80; YFX-800/80Electric hydraulic thruster:YT1 series electric hydraulic thruster:YT1-18ZB/2; YT1-25ZB/4; YT1-45Z/5; YT1-90Z/8; YT1-125Z/10; YT1-180Z/10; YT1-320Z/12; YT1-320Z/20; YT1-25/4; YT1-45/6; YT1-90/8; YT1-180/12; YT1-320Z/12; YT1-350/12;YT1-350/20; YT1-350/35; YT1-25/4; YT1-45/6; YT1-90/8; YT1-180/12BYT1 series electric hydraulic thrusters: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/12BYT1-320Z/20; BYT1-25/4; BYT1-45/6; BYT1-90/8; BYT1-180/12ED series electric hydraulic thrusters:ED-23/5; ED-30/5; ED-50/6; ED-80/6; ED-121/6; ED-201/6; ED-301/6; ED-50/12; ED-80/12; ED-121/12; ED-201/12; ED-301/12; ED-630/12BED ZED series electric hydraulic thrusters:BED30/5; BED50/6; BED80/6; BED121/6; BED201/6; BED301/6; BED50/12; BED80/12; BED121/12BED201/12; BED301/12; BED630/12

Maintenance of electric hydraulic brakes(1) The following items should be checked every 1-3 days: a. Firstly, check whether the lifting height of the thruster push rod (i.e. the HB value in Table 3) meets the specified value. When the HBmin value is reached, it should be adjusted in a timely manner, otherwise the braking will fail. It is strictly prohibited to continue using it below HBmin, and it is strictly prohibited to continue using it below HBmin as it may cause danger! It's easy to create danger! b. Check if the automatic compensation lever is too loose, and if it is loose, tighten it; Also check if the adjustment bolts in Figure 11 are loose. c. Check if the position of the spring marking has changed, and if there is any change, readjust it to the original position. d. Check the wear of the brake pad and replace it when the effective wear thickness (wear material thickness) reaches 3mm. Each replacement should be readjusted and run in. The replacement method is as follows:Firstly, use a manual device to open the brake, loosen the nut No. 13 (see Figure 1), rotate the lever 8 counterclockwise to increase the gap between the brake shoe and the brake disc, and it is best to smoothly insert the new friction plate. Then, loosen the fixing bolt (see Figure 12) and remove the old friction plate, Install a new friction plate (note: before installing the new friction plate, remove the limit pin from the old friction plate and install it into the new friction plate), tighten the fixing bolts, adjust the compensation stroke, and run in and test run according to the method in Section 3.1. (2) before use. Attention: Before replacement, the brake disc should be fixed to prevent it from rotating. Attention: Before replacement, the brake disc should be fixed to prevent it from rotating. Is the adjustment of the brake shoe follow-up device appropriate. Whether the thruster operates normally. If there is any abnormal phenomenon, stop the thruster immediately for inspection.Adjustment of electric hydraulic block brakes1. Adjustment of tile setbackAdjusting the backset of the tile is actually also adjusting the stroke of the thruster. In the brake shown in Figure 1, loosen the jam nut 11 and tighten the brake lever 10 clockwise to increase the compensation stroke of the thruster. Conversely, reduce the compensation stroke of the thruster. Adjust the compensation stroke hc to the specified value. If the compensation stroke of the thruster is adjusted too large, it is necessary to unscrew the compensation set bolt 7 and take out the compensation sleeve. At this time, the shift pin is not hindered by the triangular plate and can rotate freely counterclockwise. At this point, the brake lever can be loosened counterclockwise again, and then restored, and the compensation stroke and automatic compensation device can be readjusted.2. Equal adjustment of tile setbackThe tile setback equalization device generally does not need to be adjusted, but only needs to be adjusted after the initial or reinstallation. The method is to manually or electrically open the brake and observe the distance between the left and right pads. If the setback of the right tile is greater than that of the left tile, loosen the left set nut and turn the adjusting bolt clockwise (or loosen the right set nut and turn the adjusting bolt counterclockwise) to observe the change in the setback of the left and right tiles. If not equal, continue until equal. The equal lever should be roughly horizontal, otherwise it is necessary to move the position of the brake base so that the center line of the brake roughly coincides with the center line of the brake wheel.The adjustment of braking torque mainly depends on the compression of the spring. The rated (i.e. large) braking torque of the brake is generally adjusted at the factory, and users can choose a suitable torque value within the rated value and 50% rated value range according to actual needs, (The torque indicated on the nameplate, sample, and user manual is the rated value.) The adjustment method is to refer to the rated torque value marked on the brake nameplate, and use a wrench to rotate the spring pull rod clockwise (as shown in Figure 9), so that the indicating line in the lower seat of the spring contacts the corresponding torque value on the spring scale label. Note: [1] The adjustment position of the spring is the rated value, which can be adjusted appropriately according to specific usage. [2] After adjusting the braking torque to the rated value, the compensation stroke of the brake may change. If there is any change, adjust it according to the working stroke adjustment methodWe mainly produce YWZ1, YWZ2, YWZ3, YWZ4, YWZ5, YWZ8, YWZ9, YWZ10, YWZ12, and YWZ13 series electric hydraulic brakes. ­ Various explosion-proof brakes and TJ2 series of new energy-saving electromagnetic brakes, with complete product specifications, reliable performance, and superior quality.

The electric hydraulic thruster is mainly used for YWZ series operating brake shoe brakes, as a mechanical brake for all similar driving devices such as lifting, transportation, and driving. Structure and Action Introduction: The thruster consists of two parts: the driving motor and the body (centrifugal pump), and the body part is composed of a cover, cylinder, piston, impeller, and rotor. When energized, the electric motor drives the rotor shaft and the impeller on the rotor shaft to rotate, generating pressure inside the piston. Under this pressure, oil is sucked from the upper part of the piston to the lower part, forcing the piston and the push rod and crossbeam fixed on it to rise rapidly. By mechanically compressing the load spring through a lever (if the thruster or brake is equipped with a load spring), mechanical motion is generated. (If matched with the YWZ series hydraulic thruster, release the brake). 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. (If matched with the YWZ series brake, hold the brake). BED flameproof electric hydraulic thruster I.

Due to the mechanical electrical type used in the brake, it is also very important to inspect the electrical part of the brake.(1) Under working voltage, operate the traction machine according to its operating mechanism, load duration, and cycle. When the brake reaches a thermal stable state, measure the temperature rise of the brake coil. The measurement method adopts the resistance method in Article 8.6.2 of GB 755-2008 "Rating and Performance of Rotating Electrical Machines" for measurement and calculation. When using Class B insulation, the temperature rise of the brake coil should not exceed 80K; When using Class F insulation, the temperature rise of the brake coil should not exceed 105K. For brakes with exposed surface temperatures exceeding 6 (TC), warning signs to prevent burns should be added.(2) The withstand voltage test of the brake coil should meet the requirement of applying 1000V voltage between the conductive part and the ground for 1 minute, and there should be no breakdown phenomenon.(3) The low pull-in voltage and high release voltage of the brake electromagnet should be measured after the brake temperature rise test is completed. GB/T 24478-2009 "Elevator Traction Machines" stipulates that the low pull-in voltage and high release voltage of the brake electromagnet should be lower than 80% and 55% of the rated voltage, respectively.(4) Newer brakes are equipped with a brake monitoring switch. When the brake operates abnormally, the switch will act and the elevator will stop for protection, providing guarantee for the safe and reliable operation of the brake. But there are no relevant standard requirements, and we hope to reflect them in the standards in the future for maintenance and inspection.(5) Another key point of the brake electrical part is the control circuit of the brake coil. The fully hydraulic braking system consists of a charging valve, accumulator, foot valve, caliper brake (or other forms of brakes), as well as a brake tail light switch, pressure switch, etc. After the pressure oil is supplied to the accumulator through the charging valve, it enters the foot valve all the way. The foot valve is actually a proportional directional valve that is stepped on, and then enters the brake next to the tire. When the braking force is insufficient, the accumulator can provide short-term oil supply.There is also a type of pneumatic hydraulic brake. The pressure gas is generated by the vacuum booster pump on the engine, which pushes the brake cylinder. The right side of the brake oil tank enters the brake cylinder to increase force, and then enters the brake. The brake used in industrial brakes for cranes is both a working device and a safety device. In the lifting mechanism, the brake is used to smoothly stop the lifted or lowered goods at the required height, or to control the speed of lifting or lowering. In the operation or amplitude changing mechanism, the brake can make the mechanism stop at the required position smoothly.Hydraulic braking has the advantages of stable, safe and reliable, convenient maintenance, low power consumption, long service life, no noise, and high frequency.The company's products are widely used in domestic industries such as lifting and transportation, port machinery, metallurgical machinery, railway machinery, hydraulic machinery, mining machinery, etcThe applicable requirements, environment and detailed technical parameters of electric hydraulic caliper disc brake are specified in the product catalog.

The DC electromagnetic iron is energized and uses the electromagnetic force to eliminate the force of the brake spring, opening the brake clamp and releasing the brake. When braking, the DC electromagnet loses power and stops working. The force of the compressed spring is used to clamp the brake clamp for braking. The brake uses an electromagnet, including an electromagnet and an electronic control protection circuit. The electromagnet includes a fixed iron, a moving iron, and an iron core coil. The coil is installed on the fixed iron, and a sliding sleeve is installed on the fixed iron and moving iron. The electronic control protection circuit includes a rectifier circuit for the electromagnetic iron coil. Metallurgy, construction, chemical industry, food, machine tools, stage, etc In elevators, ships, packaging and other machinery, as well as in situations such as braking during power outages (safety measures).The brake that uses electromagnetic effect to realize braking can be divided into electromagnetic powder brake, electromagnetic eddy current brake, electromagnetic friction brake and other formsElectromagnetic powder brake: When the excitation coil is energized, a magnetic field is formed, and the magnetic powder is magnetized under the action of the magnetic field, forming a magnetic powder chain, which aggregates between the fixed magnetic conductor and the rotor. Braking is achieved by the binding force and friction force of the magnetic powder. When the excitation current disappears, the magnetic powder is in a free and loose state, and the braking effect is relieved. This type of brake has small volume, light weight, low excitation power, and the braking torque is independent of the rotational speed of the rotating parts. However, magnetic particles can cause component wear. It is convenient for automatic control and suitable for driving systems of various machines.Electromagnetic eddy current brake: magnetic field is formed when exciting coil is energized. The armature on the brake shaft rotates and cuts the magnetic field lines, generating eddy currents. The interaction between eddy currents and magnetic fields in the armature forms a braking torque. The electromagnetic eddy current brake is durable, easy to maintain, and has a wide speed range; But at low speeds, the efficiency is low and the temperature rises, so heat dissipation measures must be taken. This type of brake is commonly used in machinery with vertical loads.Electromagnetic friction brake: The excitation coil is energized to generate a magnetic field, and the armature is attracted by the magnetic yoke. The armature is connected to the flange to achieve axial braking. The use of electromagnetic brakes should be avoided to prevent dust from entering the gap of the electromagnet and affecting its engagement. For special or important occasions, additional functions of brakes should be added as needed. In low temperature environments, electric hydraulic thrusters can be used for heaters. When there are strict requirements for the transition between starting and braking processes, install a travel switch to understand the opening and closing status of the brake. For environments where maintenance and adjustment are difficult to implement, brake gap equalization devices and automatic compensation devices for friction plate wear can be installed. Adding a manual brake release device can manually open the brake in special circumstances.In addition, it is subdivided into electromagnetic disc brake, dry multi disc electromagnetic drum brake, wet electromagnetic block brake, etc. Notes editing1. Please use the electromagnetic brake in a state where there is no water or oil at all. If the friction area is contaminated with substances such as water or oil, the friction torque will be greatly reduced, and the braking sensitivity will also deteriorate. To avoid these situations in use, please add a cover.2. When using in dusty areas, please put all the brakes in the box. Electromagnetic brakes below 60KGM can be used in upright versions, even higher models can be used.3. Please use JIS0401 H6 or JS6 specifications for the long shaft size used to install the brake. Please use one of the keys specified in JIS B1301-1959 for installing the shaft.4. Considering factors such as thermal expansion, please choose a thrust of less than 0.2MM for installing the shaft.5. Please adjust the suction gap mechanically to within 20% of the specified value during installation.6.
