I. Overview:

　PZ Series Electric-Hydraulic Push Rod Plate Gate (abbreviated as Electric-Hydraulic Push Rod) is suitable for reciprocating linear (or reciprocating rotational) pushing and pulling.  Angle motion device, primarily for controlling flow and conveyance of powdery, granular, pelletized, and small-sized materials; also suitable for long-distance and high-altitude hazardous areas. It can be networked with computers for centralized (programmed) control. Now widely used in industries such as metallurgy, mining, coal, electricity, machinery, grain, cement, chemicals, water conservancy, and transportation, serving as an indispensable general power source.

II. Principle and Function:

　　1. Operating Principle: The electro-hydraulic actuator is powered by an electric motor. Through the motor's forward (reverse) rotation, hydraulic oil is outputted at pressure by a bidirectional gear pump. It then passes through an integrated oil block to the working cylinder, thereby achieving reciprocating motion of the piston rod.

　　2. Overload Automatic Protection Function: During the operation of the electro-hydraulic push rod, if the external force on the piston rod exceeds the rated output force or the piston reaches the end position, and the motor continues to rotate, the oil pressure in the circuit will increase to the set pressure. The overflow valve will then quickly and accurately overflow, achieving overload automatic protection. Although the motor is rotating, it will not be damaged.

　　3. Self-locking Function: The hydraulic push rod's oil circuit module is designed with a pressure self-locking mechanism, where the motor stops rotating, and the piston rod immediately remains stationary.  The position is where the pressure oil is in a pressure-holding state.

　　4. Speed can be infinitely adjusted within the designated speed range, as per customer requirements.

　　5. Force can be infinitely adjusted, within the designated output range, according to customer requirements.

　　6. The travel can be infinitely adjusted within the designated travel range as per customer requirements.
