What is the electrical principle of the electric push rod produced by Wuxi Zhijun Machinery Factory?

Principle and function Working principle: The current push rod takes the motor as the power source, and the hydraulic oil passes through the bidirectional teeth through the forward rotation (or reverse rotation) of the motor.

The pressure oil output by the wheel pump is sent to the working cylinder through the oil manifold block to realize the reciprocating motion of the piston rod. Automatic overload protection function: electro-hydraulic push rod

When working, if the external force on the piston rod exceeds the rated output force or the piston has reached the end point, the motor is still rotating, and the oil pressure in the oil circuit rises to a higher level.

When the pressure is constant, the overflow valve overflows quickly and accurately, realizing automatic overload protection. Although the motor is turning, it will never burn out. Self-locking function: electricity

A hydraulic self-locking mechanism is designed in the oil integrated block of the hydraulic push rod. When the motor stops, the piston rod immediately stops at a certain position and the pressure oil is maintained.

Stress state. According to the requirements of users, stepless speed regulation can be carried out within the rated speed range. Stepless adjustment within the range of rated output force.

Push and pull. Within the rated stroke range, stepless stroke adjustment can be made by electronic control.

Compared with similar products, the current push rod has the following advantages compared with electric push rod, electric actuator, hydraulic cylinder and air cylinder, and has reliable overload control.

Dynamic protection performance, even if it is overloaded or runs to the end of the trip, the motor can still run normally, but it will not burn and damage other components. Electric propulsion

Rod and electric actuator are incomparable. Electro-hydraulic push rod can be started with load, but electric push rod and electric actuator are more difficult. The same power station

Hydraulic push rod can be adjusted steplessly within its rated pulling force range, so it has a wider driving force range, while electric push rod and cylinder

You can't do it.

At the same thrust and speed, the electric energy consumed by electro-hydraulic push rod is half that of electric push rod and electric actuator. Electro-hydraulic push rod adopts all liquid.

Pressure transmission, sensitive action, stable operation, effective relief of external impact, accurate stroke control, cylinder, electric push rod, electric actuator.

Structure can't do it. The current push rod adopts the fully enclosed structure of mechanical, electrical and hydraulic integration, and the working oil circuit circulates in the pressureless closed steel cylinder without volume.

Small size, no oil leakage and convenient installation and maintenance. Under harsh environment, the interior is dust-free, water-free and rustless, and the service life is longer than that of cylinders, electric push rods,

The electric actuator lasts for a long time. Small investment. The cylinder needs to build an expensive air compressor station, the air pressure pipe leaks, the air pressure is unstable and the noise is high; Hydraulic cylinder demand

To build a hydraulic station, the electro-hydraulic push rod can only be used when the power supply is connected. Convenient maintenance. Under special circumstances, it is only necessary to replace the electro-hydraulic push rod.

The hydraulic cylinder needs to find out the cause of failure slowly first, and then carry out detailed maintenance, which affects the normal operation of all work.
