The piston rod is generally connected with the piston and the piston rod, so it needs to be carefully determined if the connection is firm and should be locked. There are also many problems caused by wear and improper connection of the connection parts. Sealing rings are used in pneumatic and hydraulic transmission system components to prevent the leakage of material media and the entry of dust and other abnormally small objects around the environment. Therefore, the cylinder piston rod sealing ring plays the role of preventing leakage.
The piston rod can be effectively used as a pressureless seal of the rotating shaft, which can not only prevent the internal grease or oil from leaking out, but also prevent the intrusion of external splashing water or dust. Mainly used for static sealing and reciprocating sealing. For example, when it can be used for rotary motion sealing, it is limited to low-speed rotary sealing devices.
The thrust on the piston rod is the theoretical fluid force acting on the piston area. The direction of the thrust is not necessarily in the vertical direction during operation, because the hydraulic cylinder, like the motor, is also a device that converts hydraulic energy into mechanical energy, so it can convert hydraulic energy into linear motion or oscillating mechanical energy.
