What is the difference between piston rod seal and piston seal
The piston rod seal has a high superiority in the application, and the link structure design of the piston is also unique to the enterprise. The connection network structure of the piston rod and the piston and the manufacturing technical method of the hydraulic cylinder with it are basically the same.

Piston rod sealThere is a high superiority in the application, and the link structure design of the piston is especially unique to the enterprise. The connection network structure of the piston rod and the piston and the manufacturing technical method of the hydraulic cylinder with it are basically the same. With advanced quality bar, hardware machinery to promote production and sales. The reason why there is good sex in the market now is that his consumption and production are better. It is gradually expanding. In this mixed effect, it can also provide more stable operation.
Piston rod sealThe difference with the piston seal is:
1. Seal different objects: The piston seal is the cylinder and the piston, the piston rod seal between the piston rod and the cylinder head. The piston rod seal forms a seal between the tight sealing device.
2. The consequences are different: if the piston seal is not good, it will affect the performance of the cylinder, and if the piston rod seal is not good, it will leak oil.
3. The position of the sealing groove is different: the piston is opened on the piston through the sealed sealing groove, and the piston rod is opened on the hole due to the sealed sealing groove.
4. The sealing ring used is different: the sealing ring used by the piston is a shaft sealing ring, while the sealing ring used by the piston rod is a hole sealing ring.
Piston rod seal, The hydraulic cylinder is composed of a cylinder body, a piston rod, a cylinder head and a sealing ring. Piston hydraulic cylinder can be divided into single rod type and double rod structure, the fixed way has cylinder fixed and piston rod fixed two ways, according to the hydraulic action has a single role and double role. In the case of a single-acting hydraulic cylinder, the pressure oil chamber is a hydraulic cylinder, and the cylinder is realized by hydraulic pressure in one direction and resists the movement of external force in the opposite direction.; And double-acting hydraulic cylinder with alternating oil intake through the two chambers in the two directions of movement of the piston, which is completed by the action of hydraulic pressure.
