The piston rod is a connection suitable for the work of the piston, most of which are used in the cylinder. It is a common component. Taking a hydraulic cylinder as an example, it is composed of a cylinder liner, a piston rod (cylinder rod), a piston, and a bearing end cover. The service life and stability of all equipment is the service life and stability of the equipment. The production and manufacture of piston rods must have a high appearance roughness Ra0.4～0.8μm, and the requirements for wear resistance are strict.
Piston components include: piston, piston ring, fulcrum ring, piston rod, etc. According to different structural types, pistons can be divided into cylindrical pistons (length larger than diameter), disc pistons (length smaller than diameter), professional differential pistons, combined pistons and plunger pump pistons.
The function of the piston rod is to connect the piston and the crosshead, transmit the force acting on the piston, and promote the movement of the piston.
