Possible Faults and Settlements
| Faults | Reason | Settlement |
| 1.Pump fails to discharge any water,The hand of pressure gauge beat violently | 1.Suction pipe don't have enough water. 2.Suction pipe blocked or the valve is locked. |
1. Inject enough water 2.unlock the inlet valve,clear the blocks 3.Exclude the air leakage |
| 2.The pump can't discharge water,the hand of vacuum meter beat heavily. | 1.The inlet valve is unlocked or silted up. 2.The resistance of suction pipe is too big or silted up. 3.The height of suction is too high. |
1.Unlock the valve or desilting 2.improve the design of suction pipe or desilt 3.Lower the height of the installation. |
| 3.The pump can't discharge water,pressure gauge shows heavy pressure. | 1.The resistance of the discharge pipe is too big. 2.The impeller blocked 3.The speed is slow. |
1.Check and adjust the outlet pipe. 2.Clear the impeller 3. Improve the speed. |
| 4.The pump doesn't rotate | The volute is silted up by the blocks. | Clear the blocks |
| 5.The capacity is not enough | 1.The blocks of the impeller or the inlet or outlet pipe. 2.The abrasion of the impeller is heavily. 3.The speed is low to normal 4.Pump is installed unreasonably or the leakage of the inlet pipe. 5.The transporting height is too high,the loss of the resistance of the inside pipe are too big. 6.The inlet valve not open enough or blocked 7.The packing seal leaks |
1.Clear the impeller or pipe. 2.Change the impeller 3.Adjust the speed 4.Install again or stop leaking.
|
| 6.The motor of the pump is overloaded | 1.The head of the pump exceeds the head of the working condition. 2.Not consider the slurry density when selecting the pump. 3.The packing press tightly |
1.Turn down the outlet valve,cut the impeller or lower the speed. 2.Select the motor again. 3.Adjust the the screw of the packing gland |
| 7.Abnormal sound in the pump, and no water out | 1.The resistance of the inlet pipe is too big. 2.The height of the suction is too high. 3.Cavitation occurred 4 .there is air in the inlet 5.The temperature of the liquid is too high |
|
| 8.pump vibrates | 1.pump cavitate 2.The block of the impeller single vane 3.The no concentricity between the pump shaft and motor shaft 4.Fasteners or foundation loose |
1.Adjust the water valve ,lower the height of the installation,reduce the resistance of the inlet. 2.Clear the impeller 3.Alignment again 4.Fasten the screw,and reinforce the foundation. |
| 9.Bearing is overheat | 1.lock the cooling water 2.lubrication is not good. 3.the lubrication oil is not clear 4.the wrong direction of the thrust bearing. 5.there is something wrong with the bearing. |
|
| 10.Packing short life | The material of packing is not good | Change the packing |
| 11.pump leak oil | 1.High oil level 2.The rubber parts invalid 3.Assembly problem |
1.Lower the oil level 2.Change rubber spares 3.Adjust the assembly |
| 12 Pump head leaking | 1.The rubber parts not press well | Assembly again or press tightly |
