Working principle of hydraulic system

The main plunger and auxiliary plunger are unidirectional structures. Under the action of hydraulic oil, the plunger extends dynamically and retracts by its own weight when the plunger returns; The three-stage piston is a two-way structure. Under the action of hydraulic oil, the three-stage piston expands and contracts. The lift cylinder has three ports

1. P2 and P3. An oil port P1 is arranged on the cylinder head, which is connected with the plunger working chamber and the three-stage piston rodless chamber, and a one-way throttle valve is arranged in the oil circuit; The oil port P2 is located at the third stage piston rod and is connected with the rod cavity of the third stage piston. The oil passage is provided with an orifice. The oil port P3 is located at the third stage piston rod, connected with the plunger working chamber and the third stage piston rodless chamber, and connected with the P1 oil circuit, which is provided with an orifice. A vent hole is arranged on the cylinder head of the third stage piston of the oil cylinder, and an exhaust plug is installed on the vent hole. The XDATA hydraulic system includes a main hydraulic system and a steering hydraulic system that share a hydraulic tank.

1. Main hydraulic system the main hydraulic system provides hydraulic power for the drilling locomotive during equipment adjustment and drilling repair, and is equipped with various valves to control the correct and safe operation of various hydraulic tools.

2. Steering hydraulic system the steering hydraulic system provides hydraulic power for the hydraulic power steering of the front axle of the vehicle. It is equipped with various valve components to control the pressure and flow direction of the hydraulic system, stabilize the maximum flow, and ensure that the vehicle steering is light, flexible, safe and reliable.
