The water ring vacuum pump does not have sufficient pumping capacity
Thread Content
Is damaged exhaust valve plates in water ring vacuum pumps a cause of insufficient pumping capacity? I looked up information online, but it’s still not entirely clear. Please have the manufacturer come and check to see if there is any air leakage in the inlet and outlet flanges; nothing has changed. By checking relevant information, the possibilities of gaps and water temperature as causes have also been preliminarily ruled out. Seeking help from my colleagues, :'(
Well, you need to look at your vacuum level – what was the design value, and what level can be achieved now? Also, is the exhaust pipeline unobstructed?
Damage to the exhaust valve flap can cause some of the gas being exhausted to flow back into the pump head, resulting in insufficient pumping capacity and vacuum level, as well as a higher temperature in the pump head
Valve disc issue； Inlet leakage and cavitation conditions ； Water level reasons ； The opening status of the reflux valve, etc.
What’s the water level like? A vacuum pump is essentially a small positive-displacement compressor; if the valve plates are damaged, the vacuum pumping performance is poor and the temperature rises... Check whether there is any erosion damage to the valve seats on the distribution plate – this could also be the cause of the problem
I have a question: is this vacuum level related to the water level?
Check for any leaks, such as nitrogen purging or internal valve leaks; we have encountered such issues before as well
1. Check whether the axial clearance of the rotor is beyond the specified limit. 2. Check whether the water temperature is above the normal level. 3. Check for leaks in the shaft seal. 4. Check whether the vacuum level in the container is too low. 5. Check whether the check valves at the inlet and outlet are in good condition
