Electro-hydraulic Plow Type Discharge Device, DYTZ Electro-hydraulic Push Rod

DYT Series New Electric Hydraulic Push Rod (Abbreviated as Electro-Hydraulic Push Rod or Push Rod) The product is suitable for reciprocating push-pull straight lines (or reciprocating rotation)  Angle movement, also suitable for applications requiring lifting, lowering, or clamping of workpieces, and capable of remote, high-altitude, and hazardous area centralized or programmed control. Widely used in metallurgy, coal, electricity, machinery, grain, cement, chemicals, water conservancy, transportation, and other industries as a general power source. Compared to electric actuators, cylinders, and hydraulic cylinders, this product has the following advantages:

1. Can start under load, while electric push rods are challenging.

2. Features overload protection capability; will not damage the motor and components.

3. The same electro-hydraulic push rod can infinitely adjust its pushing and pulling force, thus offering a wide range of driving power, which is unattainable by electric push rods and cylinders.

4. Under the same thrust and speed, the electrical energy consumption is significantly less than that of electric actuators.

5. Utilizes full hydraulic transmission for sensitive operation and smooth running, effectively cushioning external shock forces, with precise stroke control that is unattainable with cylinders or electric push rods.

6. Utilizes a fully enclosed mechanical, electrical, and hydraulic integrated structure, with the working oil circuit circulating within a pressure-free enclosed cylinder barrel. It features a compact design, no oil leakage, and is easy to install and maintain. In harsh working conditions, it does not attract dust, does not allow water entry, prevents internal corrosion, and has a longer service life than pneumatic cylinders and electric push rods.   。

7. Low investment required; cylinder needs a mining station, hydraulic cylinder requires a hydraulic station, while the electro-hydraulic actuator requires no auxiliary equipment.

Section II: Working Principle

1. An electro-hydraulic push rod is a new type of integrated electro-mechanical-hydraulic flexible transmission mechanism. It consists of an actuator (cylinder), a control unit (hydraulic control valve group), and a pressure source (pump, motor, etc.). Depending on the size of the on-site space, electro-hydraulic push rods mainly come in four structural forms (refer to model numbering). The motor, pump, hydraulic control valve, and cylinder can be mounted on the same shaft or on different shafts as needed. By connecting the motor power supply, the motor's forward and reverse operation controls the bidirectional pump to output pressure oil, which is then sent to the cylinder via the hydraulic control valve, achieving reciprocating motion of the cylinder's piston rod.

2. The hydraulic control valve assembly is mainly composed of overflow valves, hydraulic check valves, etc., and can also be designed with different functional circuit combination valves based on the working characteristics of the electro-hydraulic actuator to meet its operational requirements. Generally, there are self-locking for push-out, pull-in, and both push and pull; the overall actuator can be used horizontally, upwards, or downwards.
