What is the position and function of the seal ring in a hydraulic cylinder?
Thread Content
The hydraulic cylinder seal consists of an O-ring and a PTFE ring; what are their positions within the hydraulic cylinder (which one is on the oil side and which one is on the atmospheric side) and what are their functions?
Looking at the structure, the centrifuge’s hydraulic system has PTFE seals on the inside, outside, and at the front and back.
Generally speaking, the O-ring should be on the oil side to serve as a seal, while the PTFE ring, acting as a backup ring, should be on the atmosphere side to prevent the O-ring from deforming or being pushed out. I’m not sure if this is the case
Logically, the O-ring should be on the inside and the PTFE ring on the outside; try using a new one. If it still leaks, then it’s likely the issue you mentioned
The tetrafluoro gasket is a pressure-proof gasket designed to prevent the O-ring from deforming; it is placed on the low-pressure side, that is, the atmospheric side.
