What are the elimination methods of water ring vacuum pump

One, vacuum pump degree is not enough
Possible reasons: insufficient power supply of the motor leads to insufficient rotation speed; Insufficient water supply; The clearance between impeller and distribution plate is too large; Mechanical seal damage leads to leakage and air leakage; Excessive impeller wear; Recycled water doesn't drain out.
Exclusion method: check whether the supply voltage is within the rated voltage range of the motor; Increase the water supply (must be controlled in the correct range, otherwise it will lead to motor overload and heating); Adjust the gap between impeller and distribution plate (generally 0.15-0.20mm); Replace mechanical seal; Change impeller; Check outlet piping.
Two, can not start or start a loud noise
Possible reasons: insufficient power supply voltage of the motor; Motor out of phase operation; Long time failure of pump leads to corrosion; Inhalation of sundries in pump; Impeller drag distribution plate.
Elimination method: check whether the supply voltage is too low; Check whether the motor wiring is firm; If the pump does not use for a long time leading to corrosion can add some rust remover or open the pump cover to remove rust artificially; Open pump cover to remove sundries; Adjust the distance between impeller and distribution plate.
Motor overheating
Possible reasons: excessive water supply leads to motor overload; Motor phase deficiency; Blocked vent; Impeller drag other parts.
Elimination method: reduce the water supply to the normal range (refer to the pump instruction manual); Check whether the wiring is firm; Check vent; Open the pump cover to adjust the clearance between the impeller and other parts.
Four, insufficient flow
Possible causes: pipeline leakage of air and liquid; Increased resistance losses;
Elimination method: check the mechanical seal at the joint; Check pipeline and check valve for trouble-free.
