Jiaozuo brake

Electric hydraulic brakes are divided into short stroke block brakes and long stroke block brakes based on the length of the control device stroke. The magnet of the short stroke block brake is directly installed on the brake arm. During operation, the moving iron core rotates around the pin shaft to achieve brake release; When the magnet is powered off, it is tightly closed by the main spring. The electric hydraulic brake has a compact structure, fast tightening and releasing actions, but has a large impact force. Long travel block brakes can generate a large release force through the brake lever system, but the braking action is stable and suitable for various types of deceleration equipment., The brake block is located inside the brake wheel, and is opened by the pedal, pull rod, and convex block to compress the inner surface of the brake wheel and tighten the brake. Releasing the pedal will pull the spring back to the brake block and release the brake. This type of brake can also be operated by hydraulic or pneumatic pressure. The internally tensioned block brake has a compact structure and good dust resistance, which can be used in installation spaces and is widely used in various vehicles. The working conditions of electrically powered hydraulic brakes are as follows:

1. The common electric hydraulic brake mainly operates by pushing the actuator to open when the point is reached;

2. The braking force during braking is provided by the spring, and the electric hydraulic brake does not work at this time;

3. If you want to power on for a long time, even if the brake is in an open state for a long time, theoretically there is no problem. However, in actual use in the factory, the motor of the thruster is prone to malfunction. Generally, electric hydraulic thrusters have a wrench for manual position maintenance, which means that after opening, the claw can be manually clamped onto the support rod, and after power outage, it is still in the open state;

4. For normally open electric hydraulic brakes, the normally open state can be used, which relies on hydraulic braking and spring opening

The reasons for the oil leakage of those mobile aluminum alloy landing platforms are always intertwined. If we want to summarize them, it is the following reasons: quality, vibration, corrosion, pressure difference, pressure difference, pipe discussion, application of hydraulic components, and improper maintenance. The leakage of elevators is divided into internal leakage and external leakage, which is inevitable for a small kerosene leakage, because this is the quality of hydraulic transmission.

How to check if there is air present at the air inlet of the mobile aluminum alloy lifting platform gear pump. We can identify it by carefully listening to the sound of the running department. Add a little oil to the joint. If the sound decreases, it indicates that the seal is not sealed, and air will be leaked from the pump shaft seal or pump cover into an atmosphere containing air. We suggest that you replace the oil seal or paper gasket, and also tighten the connector or replace the gasket, joint, and seal.

The decibel emitted by the gear pump of the corresponding mobile aluminum alloy lifting platform is too large, which exceeds the decibel of the sound we usually hear. We propose to carefully check whether there is dirt and cavitation on the filter on the Oil pipeline of the gear pump, and check the standard value of the tank liquid level. Suggest refueling the oil tank and flushing it with oil. Firstly, we must check whether the oil pipes, pumps, and racks of these devices are loose from the outside. If they are loose, we must tighten them in a timely manner, otherwise resonance may occur.

Composition of electric hydraulic brake:

Electric hydraulic brakes mainly consist of thrusters, bases, brake arms, brake springs, brake pads, spring pull rods, levers, automatic distance equalization devices, lubrication devices, and other components.

The working principle of electric hydraulic brakes:

The electrical energy of the driving device is converted into mechanical energy, and the liquid flow in the cylinder is formed into a high and low pressure chamber through the rotation of the impeller, which drives the piston to move upwards. The vertical movement is then transformed into left and right swing of the brake arm through the lever mechanism, completing the brake release task. When the driving device is powered off, the mechanism amplifies and transmits the force to the brake shoe through the lever ratio under the action of spring force, completing the holding brake. The main auxiliary function of the product is the automatic equalizing device for backtracking. The technical action principle is to connect the equal backtracking device with the brake arm, and maintain the automatic equalizing of backtracking on both sides when the brake arm is opened through the rotation of the low pair of the left and right connecting plates.
