Hydraulic Actuators, Parallel Electro-Hydraulic Push Rods, Mining Explosion-Proof Electric Actuators
The DYT(B) and XDG(B) series electro-hydraulic push rods (hereinafter referred to as electro-hydraulic push rods) are suitable for reciprocating linear push-pull movements, and can be used in places where lifting, lowering, or clamping workpieces is required, as well as in remote and high-altitude hazardous areas. They can also be connected to computers for centralized (programmed) control. They are now widely used in industries such as metallurgy, mining, coal, electricity, machinery, grain, cement, chemicals, and transportation, and are an indispensable general power source.
Principles and Functions
1. Principle of Operation: The electro-hydraulic actuator is powered by an electric motor, which rotates in either direction to pump hydraulic oil through a bidirectional gear pump, producing pressure oil. This oil is then delivered to the working cylinder via an oil path module, thereby enabling the 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 automatic overload protection. Although the motor is still rotating, Will burn.
3. Self-locking Function: The hydraulic push rod's oil circuit module is designed with a pressure self-locking mechanism, so when the motor stops rotating, the piston rod immediately remains stationary. At this location, the pressure oil is in a pressure-holding state.
4. Speed can be infinitely adjusted within the designated speed range according to customer requirements.
5. Push and pull forces can be infinitely adjusted within the specified output power range as per customer requirements.
6. Can be adjusted infinitely within the designated stroke range according to customer requirements.
