Vertical axial flow pump downtime, should how to operate?

in vertical axial flow pump in use process, more or less always appear problem, for example: axial flow pump downtime, etc. , it should be how to solve these problems?

when the axial flow pump stop, the right operation method for the loss caused by axial flow pump is small, even zero loss, and wrong solutions can cause secondary damage to the machine. Stop when the axial flow pump, correct operation steps as follows:

1, the valves must be closed out line;

2, static axial flow pump stop running;

3, when the environment temperature is too low, liquid discharge within the pump must be clean, so as not to cause harm to the machine parts, appear frost crack phenomenon.

when the axial flow pump appear the following phenomenon, we should immediately stop the axial flow water pump running:

1, the axial flow pump is running, the machine connection parts become loose, should immediately stop, of axial flow pump detection and repair;

2, in pump operation, abnormal vibration or noise, it is necessary to stop the machine immediately to check;

3, if the water level is lower than the minimum water level, should stop immediately.

4, when the environment temperature is too low, should be prepared for axial flow pump heat preservation measures, in order to avoid the liquid in the pump because of ice and damages to the parts of the machine.
