Piston is a reciprocating movement in the cylinder body of an automobile engine. The piston rod is a connection part that supports the piston to do work, most of which are used in the oil cylinder and cylinder motion execution parts, and it is a moving part with frequent movement and high technical requirements. Let's further understand the difference between the piston and the piston rod seal ring?
The biggest difference is that the piston seal is the shaft seal, and the piston rod seal is the hole seal. The cylinder is composed of cylinder body, piston, piston rod, cylinder head and sealing ring.
Piston seal ring refers to the seal between the cylinder and the piston, the poor seal will affect the performance of the cylinder, and the sealing slot is opened on the piston.
The piston rod seal ring refers to the seal between the piston rod and the cylinder head, which will leak oil if the seal is not good, and the sealing groove is opened on the hole.
The sealing groove opened on the shaft should be sealed, that is, the piston seal, (hole seal ring), the sealing groove opened on the hole, should be sealed rod, that is, the piston rod seal ring, (shaft seal ring)
