Introduction of electro-hydraulic push rod

Electro-hydraulic push rod is a set of machinery, electricity, liquid as one of the hydraulic drive manipulator, suitable for the need to reciprocate push pull straight line (or reciprocating rotation of a certain Angle) motion, can also be used for the need to rise, fall or clamp work places, and can achieve remote dangerous areas of concentration or automatic control.

Electrohydraulic push rod works

Electro-hydraulic push rod is a new flexible transmission mechanism integrating machine, electricity and hydraulic, which is composed of actuator (oil cylinder), control mechanism (hydraulic control valve group) and power source (oil pump motor and so on). The electro-hydraulic putter can have various structural forms according to the site installation space and users' usage (see the outline size diagram of the electro-hydraulic putter for details, or customize the style according to users' requirements). The motor drives the positive and negative output pressure oil of the two-way hydraulic pump through the positive and negative rotation, and sends it to the cylinder through the hydraulic control valve, which also realizes the reciprocating movement of the piston rod

Structural properties of electro-hydraulic push rod

Hydraulic control valve group is mainly composed of overflow valve, oil suction one-way valve, speed regulating valve (user requirements), hydraulic control one-way valve (hydraulic lock), etc. It can also be designed according to the working characteristics of the electro-hydraulic push rod, oil circuit combination valve with different functions, to meet its working requirements. Generally there are push self - lock, pull back self - lock and push - pull self - lock; The operating speed has adjustable speed type, not adjustable speed type; The working Angle of electro-hydraulic push rod has horizontal push, upward push (including oblique upward), downward push (including oblique downward) and so on several kinds. Electro-hydraulic putter has the following advantages:

(1) Compact structure, convenient installation, small space, simple maintenance.

(2) Can be started with load, with overload protection function.

(3) Two-way hydraulic lock is set in the loop, which can stop at any position within the specified travel range and self-lock, and keep the output force unchanged.

(4) Push and pull, speed (user requirements) stepless adjustable, driving force range is very wide.

(5) Power off for some reason, the push rod locks itself to avoid accidents.

(6) Full hydraulic transmission, sensitive action, smooth operation, effective buffer external impact force, stroke control accuracy (≥0.5mm)

(7) Electromechanical and hydraulic integrated fully closed structure, the working oil circuit circulates in the closed steel cylinder without pressure, small volume, no oil seepage, in severe

Under working environment, no dust, no water, no internal corrosion, long service life.
