Non-plugging sewage pump abnormal vibration, not out of the water, startup doesn't turn?

non-clog sewage pump abnormal vibration, not out of the water, startup doesn't turn?

since blocked sewage water pump work environment and the factors of time, will inevitably produce some faults, such as: pump operation of abnormal vibration and unstable; without water or flow; Don't turn pump start-up, etc. These faults. In order to improve the work efficiency, we must find out the reason and timely exclude non-clog pump failure.

a, no jam sewage pump operation of abnormal vibration, the main cause of instability and elimination method:

1, the pump base anchor bolt is not tight or loose. ( Tighten all the anchor bolt)

2, water pipeline without independent support, pipeline vibration influence on the pump. ( To pump water pipe set independent firm support, don't let the water pump outlet pipe flange bearing)

3, loose impeller unbalanced quality and even damage or installation. ( Repair or replace the impeller)

4, water pump bearing damage up and down. ( Replace the water pump up and down bearing)

2, no jam sewage pump is not the main reasons of the lack of water or flow and elimination method:

1, the pump installation height is too high, not enough impeller submersion depth, led to the decrease of the water pump water yield. ( Control water water pump installation elevation of allowable deviation and not arbitrarily expanding)

2, water pump to the opposite. ( The pump test run before idling motor, check the steering to that of the water pump. In the process of using the above situation should check whether the power phase sequence changes)

3, water valves cannot be opened. ( To maintain the valve check valve and often)

4, water pipe is not clear or impeller stuck. ( Cleaning pipe and impeller clogs, often salvage reservoir stuff)

5, severe lower water pump abrasion and circle or be sundry jam. ( Replace the bottom ring wear-resisting, clear clutter)

6, excessive pumping the liquid density or viscosity is too high. ( Equipped with matching pumps again)

7, loss or damage to the impeller. ( Reinstall or replacement)

8, more than one Shared line, the output of the pump is not installed a one-way valve or one-way valve seal is lax. ( Install a one-way valve and replace a one-way valve seal)

three, not blocked sewage pump is started the main reason and elimination method:

1, the power switch and plug contact is not good. ( Repair or replacement)

2, control line insurance burned. ( Replacement of insurance)

3, the primary loop insurance burned. ( Replacement of insurance)

4, two phase non-clog submersible sewage pump capacitor burn out. ( Replace the capacitor)

5, three-phase non-clog submersible sewage pump phase. ( Through to phase failure circuit)
