/Separate electro-hydraulic push rod
The electro-hydraulic push rod is a hydraulically driven manipulator that integrates machinery, electricity and hydraulics. It is suitable for linear motion that requires reciprocating push and pull (or reciprocating rotation at a certain angle). It can also be used in places where working objects need to be raised, lowered or clamped, and can achieve centralized or automatic control of remote dangerous areas. It has been widely used in metallurgy, mining, electric power, coal, machinery, transportation, food, chemical industry, cement, water conservancy, building materials, transportation and other departments, and is a universal power source.
Working principle of separate electro-hydraulic push rod
The electro-hydraulic push rod is a new type of flexible transmission mechanism integrating mechanical, electrical and hydraulic. It consists of an actuator (cylinder) and a control mechanism (hydraulic control valve). Group) and power source (oil pump, motor, etc.). The electro-hydraulic actuator can have a variety of structural forms according to the on-site installation space and user usage conditions (see the electro-hydraulic actuator outline and dimension diagram for details, and the style can also be customized according to user requirements). The electric motor drives the bidirectional hydraulic pump through forward and reverse rotation to output pressure oil forward and reverse, and sends it to the oil cylinder through the hydraulic control valve, which also realizes the reciprocating movement of the piston rod.
According to the working characteristics of electro-hydraulic push rods, oil circuit combination valves with different functions are designed to meet their 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. 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.

The main advantages of the separated electro-hydraulic push rod are as follows
It can be started with load and has overload protection function.
The circuit is equipped with a two-way hydraulic lock, which can stop at any position within the specified stroke range and lock itself, while keeping the output force unchanged.
The push-pull force and speed (user requirements) are infinitely adjustable, and the driving force range is extremely wide.
If the power is cut off for any reason, the push rod will lock itself to avoid accidents.
Compact structure, easy installation, small space occupation and simple maintenance.
It adopts full hydraulic transmission, with sensitive action and smooth operation. It can effectively buffer external impact force and precise stroke control (.)
It has a fully enclosed structure with electromechanical and hydraulic integration, and 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.
Working Principle
The electro-hydraulic push rod uses an electric motor as the power source. Through the forward (reverse) rotation of the electric motor, the hydraulic oil outputs pressure oil through the two-way gear pump, and is sent to the working cylinder through the oil manifold block. , to realize the reciprocating motion of the piston rod.
Automatic overload protection function
When the electro-hydraulic push rod is working, if the external force on the piston rod exceeds the rated output force or the piston has reached the end point and the motor is still rotating, the oil pressure in the oil circuit will increase to At the set pressure, the relief valve overflows quickly and accurately to achieve automatic overload protection. Although the motor is rotating, it will never burn out.
Self-locking function
A pressure self-locking mechanism is designed in the oil circuit integrated block of the electro-hydraulic push rod. When the motor stops rotating, the piston rod immediately stays in a certain position, and the pressure oil is in a pressure-maintaining state.

Selection instructions
Electro-hydraulic push rod is mainly determined by the type of push rod and the protection of the motor. It consists of six basic elements such as grade, rated output force, stroke, rated speed and angle of use, and can also be customized according to user's special requirements.
The / type electro-hydraulic push rod represents a split electro-hydraulic push rod, which requires the motor to be explosion-proof, its maximum thrust, and its maximum stroke speed/.
