1, stuck in the test or running process
Cause: Severe scaling Solution: Remove or remove
Cause: Packing gland is too tight Solution: Relieve gland bolts
Cause: Rusty solution for internal parts: Pull the rotor firmly and clean it with oxalic acid
Cause: Foreign matter stuck on the rotor of the pump Solution: Scour with water and open the inspection
Water ring vacuum pump failure
2, motor short-circuit or overload
Cause: Winding short circuit Solution: Check motor windings
Cause: The working fluid flow is too high Solution: Adjust the inlet valve to reduce the working fluid flow
Cause: Excessive discharge pressure Solution: Reduce exhaust pressure to specified range
Cause: The amount of liquid in the inhaled gas is too high Solution: Install a separator at the inlet or reduce the flow of the working fluid
Water ring vacuum pump failure
3, low vacuum
Cause: Speed ​​drop caused by belt slip Solution: Tighten the belt
Cause: Insufficient supply of water or excessive temperature Solution: Adjust the amount of water supply to reduce the working fluid temperature
Cause: Vacuum System Leak Solution: Check for leaks in packing box tubing and pump gaps
Cause: Vacuum gauge shows incorrect solution: Replace vacuum gauge
Cause: The valve plate falls off Solution: Replace the valve plate
Water ring vacuum pump failure
4, vibration and noise
Reason: Shaft alignment is not a good solution: re-centering and locking
Cause: Loose anchor bolts Solution: Tighten the anchor bolts
Cause: Excessive fluid flow Solution: Install orifice meter to reduce flow
Reason: suction exhaust pipe wall is too thin Solution: Use a thicker wall pipe
Water ring vacuum pump failure
5, bearing parts fever
Cause: Lack or excess of grease Solution: Improve lubrication conditions
Cause: Improperly installed bearing Solution: Adjust the bearing
Cause: The bearing is rusted and the raceway is scratched. Solution: Replace the new bearing
