/Separated electro-hydraulic push rod
The separated 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 the method of separating the hydraulic station and the oil pump, which has the advantages of convenience, It is easy to assemble and can be equipped with appropriate oil pipes according to the distance. It is increasingly widely used in power plants, steel plants and other industries.
The 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, an assembly of an electric motor, a fuel tank, an oil pump, an oil filter, and a hydraulic control valve. The motor, oil pump, hydraulic control valve and hydraulic cylinder can be installed on the same axis, or they can be installed 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 motor to make the piston rod Displacement reciprocating motion. 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.
The separated electro-hydraulic actuator is mainly composed of six basic elements such as the type of the actuator, the protection level of the motor, the rated output force, the stroke, the rated speed and the angle of use. The electro-hydraulic actuator can also be customized according to the special requirements According to the requirements, it is equipped with three adjustment functions, namely speed adjustment push, pull adjustment, and stroke adjustment (stroke switch positioning).

Product performance can be based on the working characteristics of the electro-hydraulic push rod, and oil circuit combination valves with different functions can be designed. meet their job 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. Generally, there are push-out self-locking, pull-back self-locking and push-pull self-locking The operating speed is adjustable, and the working angle of the non-adjustable electro-hydraulic push rod is horizontal push, upward push (including diagonally upward), downward push (including diagonally downward), etc.

No strong vibration.
When working at full load, the push-pull force should not be exceeded.
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. According to the working characteristics of the electro-hydraulic push rod, oil circuit combination valves with different functions are designed to meet their working requirements. Generally, there are push-out self-locking, pull-back self-locking and push-pull self-locking. The operating speed is adjustable. The working angle of the non-speed-adjustable electro-hydraulic push rod is horizontal push, push upward (including diagonally upward), push downward (including diagonally downward) and other types.
The main advantages of electro-hydraulic push rods are as follows
Compact structure, easy installation, small space occupation, and simple maintenance.
Start with load and have overload protection function.
The road is equipped with a two-way hydraulic lock, which can stop at any position within the specified stroke range and lock itself, and keep the output force
unchanged.
The pulling force and speed (user requirements) are infinitely adjustable, and the driving force range is extremely wide.
If the power is cut off, the push rod will lock itself to avoid accidents.
Using full hydraulic transmission, the action is sensitive, the operation is smooth, it can effectively buffer external impact force, and the stroke control is accurate (.)
Electro-hydraulic integrated fully enclosed structure, the working oil circuit circulates in the pressureless closed steel The barrel is small in size and does not leak oil. In harsh working environments, it does not absorb dust or water, does not corrode internally, and has a long service life.
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 or replaced regularly, once a year or according to the actual work.
If the motor is left idle 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 being used for a period of time, remove the hydraulic control plug, clean the spool of the hydraulic control valve, and replace the hydraulic oil.
After being used for a long time, the push rod can be pushed and pulled 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 oil drips from the extension of the oil plug rod, replace the shaft seal.
