This section describes how to resolve the fault that the current of fire Pump Portable Pump is too high

Fire pump is used in various places of a pump equipment, it mainly undertakes the transmission of fluid and other functions, the use of mechanical energy to transfer energy to liquid, also in the process of operation, the current inside the pump is normal. If the current inside is too large, it will cause the circuit to burn, short circuit and other dangers. What causes the excessive current? How do you fix it?

I. Reasons:

1, Portable Pump the head is too low, resulting in large flow, resulting in motor overload.

2, fire pump bearing or shaft wear, seal ring wear.

3. Bearing wear, friction caused by impeller and pump shell.

4, the inlet pressure is too large, will cause excess current.

5, shaft bending, bearing caused by different centers.

6. Portable Pump The liquid level pumped by the fire pump drops below the inlet end of the impeller, resulting in intermittent water discharge and heating of the pump motor due to no water cooling.

Two, the solution:

1. Adjust the valve of the outlet pipeline, reduce the flow of the fire pump outlet, and control the current of the submersible pump in the rated current range.

2. Replace bearings and shafts.

3. Replace the bearing, impeller and pump housing.Portable Pump

4. Reduce import pressure.

5. Replace the bearing.

6, can close the valve to reduce the discharge of the sewage pump, or install the level control system.

The reason why the current of the fire pump is too large, we can see that many are caused by the wear of some important accessories. In fact, the solution is very simple, where the accessories are worn out, and which accessories are replaced. For safe use, check and replace accessories in time.
