The electro-hydraulic actuator uses an electric motor as the power source and rotates in the forward (reverse) direction of the electric motor. The hydraulic oil is outputted by the bidirectional gear pump and sent to the working cylinder through the oil manifold block to realize the reciprocating motion of the piston rod.

- Comparison with similar products< :
Compared with electric push rods, electric actuators, hydraulic cylinders and air cylinders, electro-hydraulic push rods have the following advantages:<
. Reliable automatic overload protection function allows the motor to operate normally even if it is overloaded or reaches the end of the stroke without burning or damaging other parts. Electric push rods and electric actuators are not comparable.
, electro-hydraulic push rods can be started with load, but it is difficult for electric push rods and electric actuators.
The push and pull force of the same electro-hydraulic push rod can be adjusted steplessly within its rated push and pull force range, so it has a wide range of driving force, which cannot be achieved by electric push rods and cylinders.
When the thrust and speed are the same, the electric energy consumed by the electro-hydraulic push rod is half of that of the electric push rod and electric actuator.
The electro-hydraulic push rod adopts full hydraulic transmission for sensitive and smooth operation, which can effectively slow down the external impact force and accurately control the stroke. This cannot be achieved by cylinders, electric push rods and electric actuators.
The electro-hydraulic push rod adopts a mechanical, electrical and hydraulic integrated fully enclosed structure. The working oil circuit circulates in a pressureless closed steel cylinder. It is small in size, does not leak oil, and is easy to install and maintain. In harsh environments, it does not absorb dust, does not enter water, and does not rust internally. Its service life is longer than that of cylinders, electric push rods, and electric actuators. <
, small investment. The cylinder needs to build an expensive air compressor station. The air pressure pipe leaks easily, the air pressure is unstable and the noise is high. The hydraulic cylinder needs to build a hydraulic station, while the electro-hydraulic push rod only needs to be connected to the power supply to be used. <
, easy to maintain. Under special circumstances, the electro-hydraulic push rod only needs to be replaced, while the hydraulic cylinder needs to slowly identify the cause of the failure and then conduct careful repairs, which affects the normal operation of the entire work.

- 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.
-. -
Hydraulic oil should be filtered regularly or replaced once a year or at a self-determined cycle based on actual work.
-. -
The insulation of the motor must be checked before it is put into use if it has been idle for a long time.
-. -
Simple troubleshooting

If it does not work when it is first installed, check if the motor is not running or there is insufficient oil.
After being used for a period of time and unable to operate, remove the hydraulic control plug, clean the spool of the hydraulic control valve, and replace the hydraulic oil.
- After using for a long time, the push rod can push and pull without load but 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.
