D electro-hydraulic push rod
D separate electro-hydraulic push rod is a kind of electro-hydraulic push rod that is different from the integral straight electro-hydraulic push rod. It adopts a hydraulic station and oil pump
The separation method is convenient and easy to assemble, and suitable oil pipes can be equipped according to the distance. It is increasingly widely used in power plants, steel plants and other industries.
D electro-hydraulic push rod is a new type of actuator that integrates mechanics, electricity, hydraulics and instruments. It uses a hydraulic cylinder as the main body and is an assembly of motor, oil tank, oil pump, oil filter and hydraulic control valve. The electric motor, oil pump, hydraulic control valve and hydraulic cylinder can be installed on the same axis or on different axes as needed. There is an oil tank and a mounting bracket in the middle. Just turn on the control power of the electric motor to make the piston rod move reciprocally. The expansion and contraction of the piston rod is controlled by the forward and reverse rotation of the motor.
Note: Stepless adjustment can be made within the rated range according to user requirements.
D separate electro-hydraulic actuator is mainly composed of six basic elements such as the type of the push rod, the protection level of the motor, the rated output force, the stroke, the rated speed and the angle of use. It is required to be equipped with three adjustment functions: speed adjustment push, pull adjustment and stroke adjustment (stroke switch positioning).

Product performance: Oil circuit combination valves with different functions can be designed according to the working characteristics of the electro-hydraulic push rod to meet its working requirements. The hydraulic control valve group is mainly composed of a relief valve, an oil suction check valve, a speed regulating valve (user requirements), a hydraulic control check valve (hydraulic lock), etc. It generally has push-out self-locking, pull-back self-locking, and both push-pull and push-pull self-locking. The operating speed is adjustable. The working angles of speed-type non-adjustable electro-hydraulic push rods include horizontal push and upward push (including diagonal upward) and downward push (including diagonal downward).
Working environment temperature: -℃~℃
Relative humidity: %
No strong vibration.
The push-pull force should not be exceeded when working at full load.
The altitude complies with regulations.
Structural performance of electro-hydraulic push rod
The hydraulic control valve group is mainly composed of a relief valve, an oil suction check valve, a speed regulating valve (user requirements), a hydraulic control check valve (hydraulic lock), etc. It can also be based on the electro-hydraulic The working characteristics of the push rod design oil circuit combination valves with different functions to meet its working requirements. Generally, there are push-out self-locking, pull-back self-locking and both push-pull and push-pull self-locking. The operating speed is adjustable, non-adjustable, and the working angle of the electro-hydraulic push rod is horizontal. Push upward (including diagonally upward) and push downward (including diagonally downward). Wait a few.
Electro-hydraulic actuators have the following main advantages:
Compact structure, easy installation, small space occupation, and simple maintenance.
It can be started with load and has overload protection function.
The circuit is equipped with a two-way hydraulic lock that can stop at any position within the specified stroke range and self-lock while keeping the output force
unchanged.
Push and pull force speed (user requirement) is steplessly adjustable and the driving force range is extremely wide.
If the power is cut off for some reason, the push rod will lock itself to avoid accidents.
It adopts full hydraulic transmission for sensitive action and smooth operation, which can effectively buffer external impact force and precise stroke control. Oil leakage, no dust collection, no water ingress, no internal corrosion, long service life in harsh working environments.
Maintenance of electro-hydraulic push rod
In order to ensure the service life of the high-pressure oil pipe, the oil pipe must be fixed with rubber.
When using hydraulic oil, it should be filtered regularly or replaced once a year or at a self-determined cycle based on actual work.
If the motor is not used for a long time, the insulation of the motor must be checked before being put into use.
Simple troubleshooting for electro-hydraulic push rods
If it cannot move when it is first installed, check if the motor is not running or there is insufficient oil.
If it cannot operate after a period of use, remove the hydraulic control plug, clean the hydraulic control valve spool, and replace the hydraulic oil.
After using for a long time, the push rod can push and pull without load and cannot stand with load. Replace the seal for the upper hole of the piston in the cylinder.
If the sealing surface leaks, replace the seal. If there is oil dripping from the extension of the oil plug rod, replace the shaft seal.
