Fault

Reason

 Elimination method

1. The water level in the pump is too high

Ø Check and adjust water level to normal

Difficulty in starting 

2. Power supply problem

Ø Check for power or short circuits

Stuck during test run or operation

3. Severe scaling

Ø To remove or pickling

 

4. Packing gland is too tight

Ø Loosen gland bolts

 

5. Internal parts rust

Ø Press the rotor hard and clean with oxalic acid

 

6. The foreign body jammed the pump rotor

Ø Flush with water and open for inspection

 

 

 

 

1. Improper adjustment of current protection of electric control cabinet

Ø Adjust current rating of thermal relay

Short circuit or overload of motor

2.short circuit in winding 

Ø Check motor winding

 

3. The working fluid flow is too high

Ø Adjust inlet valve to reduce working fluid flow

 

4.Excessive exhaust pressure

Ø Reduce exhaust pressure to the specified range

 

5. Excessive liquid content in inhaled gas

Ø Install separator at the entrance or reduce the working fluid flow

 

 

 

 

1. Severe scaling

Ø Remove with acid pickling

low vacuum

2. The belt slipped and caused the speed to drop

Ø tightening belt

 

3. Insufficient water supply or excessive temperature

Ø Adjust the water supply to reduce the working fluid temperature

 

4.Vacuum system leakage

Ø Check packing box pipe and pump clearance for leakage

 

5. The vacuum gauge does not display correctly

ØReplace the vacuum gauge

 

6. Valve plate fall off

Ø Replace the valve plate

 

 

 

 

1. High temperatures cause cavitation

Ø Use cooling water

 

2.Friction or ejection of gas

Ø Draw the vent out of the room

High vibration and noise

3. Axis alignment is not good

Ø Re-neutralize the lock

 

4. The anchor bolt is loose

Ø Tighten the anchor bolts

 

5. The working fluid flow is too high

Ø Install orifice meter to reduce flow

 

6. The suction and exhaust pipe wall is too thin

Ø Use a thick wall of the trachea

 

 

 

 

1. The belt is too tight

Ø Properly loosen the belt

 

2. Motor reducer water ring pump is out of alignment

Ø Re-neutralize

Bearing heating

3. Lack or excess of lubricating oil

ØImprove lubrication condition

 

4. Improper bearing installation

Ø Adjust the bearing 

 

5. The bearing is corroded and the raceway is scratched

Ø  rebearing
