Let’s share: What are the hazards of too low bearing temperatures in a booster expander, and what causes them?
Thread Content
Hazard: Too low a temperature can result in excessively small bearing clearances, which affects normal operation; in severe cases, it can also cause the lubricating oil to solidify. Reasons: 1. The shaft seal gap is too large. 2. The shaft seal gas pressure is too low. 3. Cold gas backflow when the device is parked
Thermal expansion and contraction work on this principle
The main reasons are a poor sealer or low pressure of the sealing gas.
Low seal gas pressure or damaged seal causes heat loss
It is mainly caused by the low pressure of the seal air in the expander! It’s very dangerous!
