Roots vacuum pump will inevitably break down in use. It is not terrible to break down. As long as we find out the causes, we can solve the problems pertinently, so as to better ensure the use efficiency of the equipment.
1. The circulating water pump works abnormally or trips, the butterfly valve at the outlet of the circulating pump is reduced or fully closed, and the circulating water inlet and outlet valves of the condenser are closed by mistake, resulting in the reduction or interruption of the circulating water volume.
2. Condenser stainless steel pipe is dirty.
3. Abnormal operation or tripping.
4. The vacuum breaking valve is opened by mistake or not closed tightly, the vacuum system pipeline and other equipment systems are damaged or leaked, and the vacuum system valve has external leakage fault.
5. The steam supply pressure of shaft seal is obviously reduced, and the water level and negative pressure of shaft heater are abnormal.
6. The water level of condenser hot well of vacuum pump is too high.
7. Vacuum system of small turbine leaks.
8. The explosion-proof valve of low-pressure cylinder of large and small vacuum pump is broken.
Knowing the cause of the vacuum drop sign of Roots vacuum pump condenser can solve the problem pertinently, so as to quickly restore the service efficiency of the equipment, reduce the occurrence of equipment failure and prolong its service life.
