1, centrifugal water pump
suction, pressure gauge throbbing.
Reason: perfusion of water diversion is not enough;
There is air pump inner product;
The suction pipe and pipe leakage.
Solution: pouring enough water diversion;
Check the line to eliminate leakage phenomenon.
2, vacuum gauge indicates high vacuum, the pump is still not bibulous.
Reason: the bottom valve didn't open or serious congestion;
Suction pipe resistance;
On the suction height is too high.
Solution: check the bottom valve valve flexibility;
To remove a blockage;
Try to make simple suction pipe;
Reduce the suction height.
3, water pump vibration reasons: pump shaft and motor shaft is different;
Bearing clearance is too large.
Solution: adjust the pump and motor axis alignment;
Through balance test of impeller unbalanced weight requirement at about 3 g;
Replace the bearing.
4, water pump bearing heating reasons: lack of oil bearing and much lubricating oil viscosity;
Bearing wear clearance is too large;
Different heart pump and motor.
The solution: come on;
Changing the oil or low viscosity oil;
Replace the bearing;
Adjust the pump and motor, guarantee the concentric.
5, export pressure gauge indicates pressure, pump water little or no water.
Reason: outlet pipe resistance;
Steering is wrong;
Speed is not enough.
Solution: reduce pipe resistance;
Check the motor steering;
Remove the impeller blocking object;
Increase the speed.
6, water pump power consumption is too large.
Reason: too tightly on the packing;
Packing room fever;
The impeller wear;
Water pump is too large.
The solution: relax gland;
Turning down the gate valve;
Reduce the traffic.
7, water pump noise big reason: pump and motor installation different heart;
The pump and motor bearing wear, have to beat.
Solution: adjust the pump and motor, assure concentric;
Replace the new bearing.
8 abnormal sound, water pump, pump without water.
Reason: the suction resistance is too large;
Suction height is too large;
There are air into the suction pipe;
Deserves to send liquid temperature is too high.
Solution: check whether there is any jam on suction pipe;
Clean up the bottom valve, reduce the liquid temperature or lower suction height.
9, the pump flow is lower than the design flow.
Reason: the impeller blocking;
Sealing ring wear clearance is too large;
Speed is not enough.
Solution: remove blockage;
Replace the sealing ring;
Increase the speed to the specified value on the nameplate. water pump
