The Ed series electric hydraulic thrusters are mainly made of cast aluminum alloy for the outer shell, which is very beautiful in appearance and lightweight in quality. The motor is mainly made of a non immersed structure. The surface of the motor shaft and push rod of the Ed series electric hydraulic thrusters are treated with hard chromium plating, which has excellent sealing performance and can effectively extend the service life of the sealing componentsYwz, Ywz4, Ywz5, Ywz8, Ywz9, YWZ13 and other series of electric hydraulic brakes use Yt1, Ytd, ED, and YT3 series thrusters as the driving devices for the brakes.Mainly suitable for mechanical braking of lifting, transportation, metallurgy, mining, port, and construction machinery movement devices. The brake using a single push rod electric hydraulic thruster as the driving device has excellent technical indicators such as fast action speed, long service life, and allowable high operating frequency compared to the brake using a double push rod.Service conditions and procedures-Environmental temperature: -25 ℃ n+45 ℃ - The relative humidity of the air is not more than 90%, - In a medium without explosion risk, and there is no gas or conductive dust in the medium that can corrode metals and damage insulation - The elevation of the installation site meets the GB755-87 standard; For three-phase 380v50Hz AC power supplyWorking principle and structural characteristics1. Structural featuresThe brake mainly consists of a base, brake arm, brake shoe, spring, lever, thruster, and other parts. The thruster mainly 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 shaft.2. Working principleWhen the thruster is powered on, the electric motor drives the shaft and the impeller on the shaft to rotate, generating pressure inside the piston, causing the push rod fixed on the piston to quickly rise, and pushing the connecting lever to compress the main spring to open the brake shoe, allowing the mechanism to move. When the thruster is powered off, the force of the main spring compresses the brake shoe onto the brake wheel of the mechanism, causing it to stop moving.The adjustment of the brake shoe backlash of the electric hydraulic brake, due to the automatic clearance adjustment performance of the electric hydraulic brake, the gap between the left brake shoe and the brake shoe can always remain unchanged as the brake shoe wears, but the gap between the right brake shoe and the left brake shoe gradually increases with the wear of the brake pad. It is necessary to adjust it in a timely manner according to the situation to ensure that the brake shoe backlash on both sides is basically uniform.The stroke adjustment of the electric hydraulic thruster ensures that the working stroke of the electric hydraulic thruster is ideal as long as the brake shoe of the electric hydraulic brake has less backlash. Therefore, it is necessary to adjust the height of the electric hydraulic thruster. The electric hydraulic thruster consists of two parts, driving the electric motor and the body (centrifugal pump). The body part is composed of a cover, cylinder, piston, impeller, and rotor. Electric hydraulic thrusters are often used in conjunction with brake frames and are widely used for braking various transmission devices. It can continuously work S1 and continue working S3, with a basic ambient temperature of+50 ℃.The rated current in the table of electric hydraulic thrusters refers to the line end current during rated operation, but if the power supply is not at the rated value, it will inevitably cause corresponding changes in the rated current. Environmental temperature: -20 ℃~+50 ℃, hydraulic oil: DB-25 (SY1351-77) When it is below -20 ℃, YH-10 hydraulic oil can be used without a heater. When using DB-25 hydraulic equipment, a heater must be installed. The travel time is measured at an ambient temperature of 20 ℃.When the electric hydraulic brake is energized, the electric motor drives the transmission shaft and the impeller on the shaft to rotate, causing pressure to occur inside the piston. Under this pressure, 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 rise rapidly. Mechanical movement occurs by mechanically tightening the load tension spring through a lever (if the thruster or brake is equipped with a load tension spring)

Advantages and disadvantages of electro-hydraulic drum brake:The advantages and disadvantages of the above drum brakes can be analyzed and compared as follows.(1) First of all, in terms of braking efficiency, under the condition that the structural parameters are basically the same, the automatic booster brake is fully utilized due to the increasing effect of friction force, and the braking efficiency is high, followed by the balanced brake, and the unbalanced brake is low. On the other hand, the friction coefficient between the brake shoe and the brake drum is itself an unstable factor, It varies in a wide range with the material properties, temperature and surface conditions of the brake drum and friction pad (such as whether they are contaminated with water, oil, etc.).The braking efficiency of the automatic booster brake is sensitive to the friction coefficient, so it is very unstable.(2) Drum brakes make use of friction potentiation to ensure certain braking efficiency to varying degrees. However, in use, the stability of braking efficiency is poor because the friction coefficient is not stable.(3) When the brake works, most of the heat generated by friction is transferred to the brake drum to raise its temperature. In order to reduce the temperature rise, the brake drum should have a large heat capacity.Drum brake:(1) Simple unbalanced brake: This is a common hydraulic wheel brake. In this kind of brake, the auxiliary potential shoe, by the action of friction force, causes the pressure on the brake drum to be much greater than the reducing potential shoe. In order to make the two shoes wear evenly, make the auxiliary potential shoe longer than the reducing potential shoe, so that the opening force acting on the shoe is different, but the friction torque is equal, so as to achieve the purpose of uniform wear.(2) Balanced brake: the balanced brake has two types: one-way potential assistance and two-way potential assistance. The one-way potential assistance balanced brake has the function of automatic potential assistance when each shoe is hard pressed against the brake drum, but when reversing, it will become a reduced potential shoe, with poor braking effect. Because of its large one-way braking torque, it is called one-way balanced brake. The front and rear brake wheel cylinders of the two-way balanced brake drive the two floating brake shoes. When braking forward, all the wheel cylinder pistons move outward under the action of hydraulic pressure, pressing the two shoe pads against the brake drum. Under the action of the friction torque of the brake drum, both shoes rotate in the direction of wheel rotation until the support at the outer end of the piston of the two wheel cylinders is pushed back to the end face of the wheel cylinder. This brake has good contact and uniform wear, The braking efficiency is high, which is mostly used by modern vehicles.(3) Automatic booster brake: this structure bl130 uses this kind of brake shoe. The lower ends of the left and right shoes are connected by floating adjusting rods. When the upper end of the left shoe is pressed by the slave pump to the brake drum, the opening force of the slave pump is transmitted to the lower end of the right shoe through the potential assistance of the shoe. This thrust is greater than the opening force of the slave pump. The braking torque of the right shoe with the same potential assistance is greater than that of the left shoe, The braking efficiency of the whole brake is higher than that of the balanced brake, and it has a device that automatically adjusts the shoe clearance.

What are the differences between drum brake and disc brakeThe brake is a device with the functions of decelerating, stopping or maintaining the stop state of moving parts (or moving machinery). It is a mechanical part that stops or decelerates the moving parts in the machine. Commonly known as brake, brake. The brake is mainly composed of brake frame, brake parts and control devices. Some brakes are also equipped with automatic brake clearance adjustment device. In order to reduce the braking torque and structural size, the brake is usually installed on the high-speed shaft of the equipment, but the large equipment with high safety requirements (such as mine hoist, elevator, etc.) should be installed on the low-speed shaft close to the working part of the equipment.Advantages and disadvantages of electro-hydraulic drum brake:The advantages and disadvantages of the above drum brakes can be analyzed and compared as follows.(1) First of all, in terms of braking efficiency, under the condition that the structural parameters are basically the same, the automatic booster brake is fully utilized due to the increasing effect of friction force, and the braking efficiency is high, followed by the balanced brake, and the unbalanced brake is low.

What are the differences between the two braking modes?1. Drum brake is to install two semi-circular brake pads in the wheel hub, and use the "lever principle" to make the brake pads contact with the inner surface of the wheel drum to generate friction and brake. The disc brake uses the brake caliper to control the two brake pads to clamp the brake discs on the wheels. When the brake pads clamp the disc, friction will occur between them.2. The brake system of drum brake can use low oil pressure. The diameter of drum brake will increase after heating, and the brake response will not be as expected. The heat dissipation of the disc brake is better than that of the drum brake, and the brake failure will not be caused by brake recession when the brake is continuously applied. The braking force of the left and right wheels of the disc brake is relatively average, and the brake disc has good drainage, which can reduce the phenomenon of poor braking caused by water or sediment.3. The hand brake mechanism of drum brake is easy to install. Some rear wheels are equipped with disc brakes, and the drum hand brake is installed in the center of the brake disc. The pedal force of the brake is not easy to control, which is not conducive to the emergency braking action. The friction area between the disc brake pad and the brake disc is smaller than that of the drum brake, so the braking force is weak. In order to improve the shortcomings of the braking force, it is necessary to increase the pedal force or increase the oil pressure to improve the braking force.4. Drum brake parts processing is relatively simple, low manufacturing cost, but more structural parts. Disc brakes are simple in structure and easier to maintain, but the brake pads are worn out and replaced frequently.

Supply ED series electric hydraulic thruster ED-121/6 ED-201/6 accessoriesOil stains on the shoe friction plates of the electric hydraulic thruster: When there is oil stains on the brake shoe friction plates and brake drums during driving, as well as burning and carbonization on the surface, it should be promptly eliminated. Otherwise, it may cause problems such as decreased braking performance, ineffective braking, and brake deviation. The specific method of elimination is to first repair the oil seal, as oil stains, burning, and carbonization are all caused by the oil leakage of the hub oil seal, which causes lubricating grease to enter the brake. Gasoline can be used to clean the oil stains on the brake shoe friction plates. When the oil stains are severe, coarse sandpaper can be used to remove the stains on the brake shoe friction plates. Alternatively, low heat can be used to heat the brake shoe friction plates to allow the oil stains that seep between the friction plates to seep out. Then, gasoline can be used to clean and repair them before use.Water ingress into the electric hydraulic thruster: During driving, when the car wades through water, there may be water ingress into the electric hydraulic thruster, resulting in a decrease in braking effect. In this case, the method of braking while driving should be adopted to restore braking performance as soon as possible. The method of braking while driving is to use your right foot to step on the accelerator pedal and your left foot to step on the brake pedal on a spacious and straight road with good road conditions. Drive in medium speed, increasing the friction between the friction plate of the electric hydraulic actuator and the brake drum as much as possible, and using friction to generate heat to quickly evaporate the moisture, thus achieving the goal of restoring braking performance.Brake pipeline rupture: A brake pipeline rupture can lead to brake failure or inability to release the brake. When encountering this situation during the operation of the electric hydraulic thruster, it should be stopped immediately for handling. The specific method is to take a suitable piece of inner tube rubber, wrap it around the crack, and then use a metal clip to clamp it at the inner tube rubber, and tighten the locking bolt; Thin iron or copper sheets can also be used instead of metal clips for skin tubes, and then wrapped tightly with iron wire to check for air leakage before emergency use. If there are adhesives such as quick-drying adhesive, the trachea can be polished clean and repaired with thin iron, copper, rubber, etcUsage 201 ImageThe ED series electric hydraulic thrusters are mainly used as operating components for the YWZ4, YWZ5, YWZ8, YWZ9, and YWZP series electric hydraulic block brakes, widely used in industries such as lifting and transportation, metallurgy, mining, ports, and construction.Normal working conditionsMotor 1/2 three-phase AC asynchronous motor, in accordance with (G 755-87) regulations, insulation level: F levelUsage conditions:Continuous 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%Vertical installation: piston connection block facing upwards, horizontal installation: marked label facing upwards: (ED630/12 male is suitable for vertical installation)ED-50/6 ED-80/6 supply ED series electric hydraulic thruster ED-201/12 ED-121/12 supply ED series electric hydraulic thruster ED-121/6 ED-201/6 supply ED series electric hydraulic thruster ED-301/6 ED-301/12 supply ED series electric hydraulic thruster ED-50/6 ED-80/6 supply ED series electric hydraulic thruster ED-40/6 ED-23/5 supply ED series electric hydraulic thruster ED-70/6 ED-30/5 supply ED series electric hydraulic thruster ED-50/12 ED-80/12
