An electric push rod is a hydraulic manipulator integrated with machinery, electricity, and fluid power, suitable for applications requiring reciprocating linear (or reciprocating rotational) motion. It can also be used in situations that necessitate lifting, lowering, or clamping workpieces, and allows for centralized or automatic control from a distance in hazardous areas.

Structural performance

The hydraulic control valve assembly consists mainly of an overflow valve, a suction check valve, a throttle valve (as per customer requirement), and a hydraulic lock valve (check valve).

Also, based on the working characteristics of the electro-hydraulic push rod, different function oil circuit combination valves can be designed to meet its operational requirements. Generally, they include features such as push-out with self-locking and pull.

Retractable and sliding locks are all self-locking; operating speed includes adjustable and non-adjustable types; the working angle of the electro-hydraulic actuator includes horizontal push, upward push (including diagonal upward), and downward push (including diagonal downward) among others. The main advantages of the electro-hydraulic actuator are as follows:

(1) Compact structure, easy installation, minimal space requirement, and simple maintenance.

(2) Can start under load, equipped with overload protection function.

(3) The circuit is equipped with a two-way hydraulic lock, allowing it to stop at any position within the specified travel range and automatically lock in place, while maintaining constant output force.

(4) Push-pull force and speed (as per customer's requirement) are infinitely adjustable with a wide range of driving power.

(5) In case of power outage, the push rod will automatically lock to prevent accidents.

(6) Full hydraulic transmission ensures sensitive operation and smooth running, effectively buffering external impact forces; stroke control (≥0.5mm)

(7) All-in-one mechanical, electrical, and hydraulic enclosed structure; working oil circuit circulates within a pressure-free, enclosed steel cylinder; compact in size, leak-proof, and suitable for harsh conditions.
