Hydraulic push-pull cylinder pushes and pulls the rotating main shaft

The hydraulic push-pull cylinder pushes and pulls the main shaft that rotates bai, and the middle is connected with the oil pipe by a rotating oil jacket. The hydraulic push-pull cylinder is a hydraulic actuator that converts hydraulic pressure energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has simple structure and reliable work. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is stable, so it is widely used in the hydraulic system of various machinery. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device.

The buffer device and exhaust device depend on the specific application, other devices are essential. The single-rod double-acting piston hydraulic cylinder is provided with a piston rod only on one side of the piston, so the effective action areas of the two chambers are different. When the oil supply is the same, different chambers feed oil, and the piston moves at different speeds; when the load force to be overcome is the same, different chambers feed oil, the required oil supply pressure is different, or after the system pressure is set, the sanitation The load force that the garbage truck hydraulic cylinder can overcome in two directions is different.
