What are the characteristics of plunger hydraulic cylinder?

The plunger Hydraulic Cylinder is a hydraulic actuator that converts hydraulic energy into machinery and performs linear reciprocating motion (or swinging motion). The structure is simple and the operation is reliable. When reciprocating, the rabbit can enter the deceleration device without driving clearance and smooth movement, so it is widely used in various mechanical hydraulic systems.
Features of plunger hydraulic cylinder:
(1) It is a single-acting thin cylinder: the hydraulic pressure only moves in one direction: Gui Ducheng depends on other external forces or the dead weight of the plunger;
(2) The plunger is only supported by the cylinder liner instead of the cylinder liner, so the cylinder liner is easy to process and is suitable for the production of long-stroke hydraulic cylinders;
(3) During operation, the plunger is always under pressure, so it must have sufficient rigidity;
(4) The plunger component is generally large. When it is placed horizontally, its self-weight is easy to sag, resulting in wear of the seal and the guide rail, so its straight application is more advantageous.

The plunger hydraulic cylinder can only complete one-way movement, and the return stroke is driven by gravity or spring force or other forces. In order to get two-way movement, pair and rearrangement are generally used. The plunger is tightened at the end. In order to ensure that the piston cylinder has sufficient thrust and stability, the plunger is generally thick and has a large component. Horizontal installation is prone to unilateral wear, so the plunger cylinder should be installed straight. In order to reduce weight and improve stability, horizontal tubes are used to make plungers for seamless steel tubes.
