Pipeline sewage pump troubleshooting

First, the power is too large

Reasons: Solution:

1, the proportion of transmission medium is too large 1, reduce the viscosity or increase perfusion pressure

2, pipe-type sewage pump axis and the motor axis error is too large 2, readjustment

3, a mechanical friction 3, check where the friction, overhaul

Second, lack of traffic

Reasons: Solution:

1, impeller damage 1, replace the impeller

2, speed is not enough 2, check the motor and power supply lines

3, there are clogs in the pipeline 3, remove the blockage

Third, lack of head

Reasons: Solution

1, there is air in the conveying medium 1, re-perfusion liquid or emptying gas

2, impeller damage 2, replace the impeller

3, speed is not enough 3, check the motor and power supply lines

4, the proportion of transport medium is too large 4, reduce the viscosity or increase perfusion pressure

Fourth, the shaft end leakage and seal leakage

Reasons: Solution:

1, the shaft end snap ring gap is too large, the ring loose 1, adjust the snap ring screw

2, the suction height is too high, cavitation 2, reduce the installation height

3, mechanical seals, static ring wear, spring pressure 3, the reason for wear and tear materials, adjust the spring

4, mechanical seal, static ring is not good fit 4, adjust the dynamic and static ring

Five, can not hit the liquid

Reasons: Solution:

1, there is air in the suction tube 1, re-perfusion liquid or emptying gas

2, suction tube leak 2, check the suction pipe

3, pipe-type sewage pump perfusion fluid less than 3, re-infusion of liquid

4, there are debris sucking in the pipeline 4, remove clogged debris

5, pipeline sewage pump reverse 5, adjust the steering

6, suction height is too high 6, reduce the installation height

Six, pipeline sewage pump vibration

Reasons: Solution:

1, pipe-type sewage pump axis and the motor axis error is too large 1, readjust

2, Suction height, resulting in cavitation 2, reduce the installation height

3, there are mechanical friction 3, check where the wear and tear, maintenance

A garage just looks empty without quality aluminum trolley jacks. Hydraulic aluminum trolley jacks can help make quick work of a tire change or brake job, but having the right automative service Aluminum Trolley Jack is more than a matter of convenience, it's safety.
