Plug-in valve with electric actuator, explosion-proof electric actuator, straight hydraulic push rod

The DYT series hydraulic push rods are suitable for reciprocating linear (or reciprocating rotational) motion within a certain angle. They are used in applications where lifting, lowering, or clamping objects is required, as well as in remote and high-altitude hazardous areas. They can also be networked with computers for centralized (programmed) control. Now widely used in industries such as metallurgy, mining, coal, power, machinery, grain, cement, chemicals, water conservancy, and transportation, they are an indispensable general-purpose power source.

Part 1:1Structure:
    The electric actuator is composed of components such as an electric motor, reduction gears, screw thread, copper nut, guide sleeve, piston rod, bearing housing, bearing housing, spring, cylinder seat, connecting fork, and photoelectric proximity switch unit (optional for customer selection).
2Operating Principle:
 The motor drives the lead screw nut after being reduced by a first or second-stage gear, converting the motor's rotational Dynamic conversion to linear motion, advantageous The push rod performs reciprocating motion through forward and reverse motor operation. Output thrust and pull force are equal. The stroke can be increased by varying the lever arm lengths. 3Overload automatic protection feature:
Electromagnetic rod overload automatic protection device, when the rod stroke reaches  Location or load exceeds rated thrust  Valve stem The power supply will automatically shut off, serving as a protective measure to prevent damage to the motor and other components; however, it should not be used as a limit during normal operation. Position switch usage requires an additional external limit switch device to be configured on the machine. Our factory can provide photoelectric proximity switch configurations for customers. Positioning to control the rod's normal start and stop.

One,Principles and Functions

1、Operating Principle: The electro-hydraulic push rod is powered by an electric motor, which, through its forward (or reverse) rotation, forces hydraulic oil through a bidirectional gear pump to produce pressure oil. The oil is then routed through an integrated manifold to the working cylinder, achieving reciprocating movement of the piston rod.

2、Overload Auto-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, the motor continues to rotate. At this point, the oil pressure in the oil circuit increases to the set pressure, and the overflow valve rapidly and accurately overflows, achieving overload auto-protection. Although the motor is rotating, it will never be damaged.

3、Self-locking Function: A hydraulic self-locking mechanism is integrated into the oil circuit module of the electro-hydraulic push rod, allowing the piston rod to stop immediately upon motor shutdown.  At the location, the pressure oil is in a pressure-holding state.
