O-ring
O-ring material
1. O-ring material selection, mainly considering the following aspects:
1) The working state of the O-ring, which refers to whether the O-ring is used for static sealing or dynamic sealing, whether it slides or rotates.
2) The working condition of the machine refers to whether the machine is working continuously or intermittently, and the length of each interruption should be taken into account, whether there is an impact load acting on the sealing part.
3) The condition of the working medium, whether the working medium is a liquid or a gas, and consider its physical and chemical properties.
4) Working pressure, pressure magnitude, fluctuation amplitude and frequency, and the maximum pressure that occurs instantaneously.
5) Operating temperature, including instantaneous temperature and alternating temperature between heat and cold.
