Several matters needing attention when using the axial flow pump can not be ignored

axial flow pump by the rotating impeller blades of liquid caused by the force along the axis direction conveying pump, vertical, horizontal, oblique type and tubular several kinds.

axial flow pump impeller with 2 ~ 7, in the circular tube shell rotary pump. On the impeller in the pump at the top of shell with fixed guide vane, is used to eliminate the rotary motion, liquid into the axial movement, and can convert the kinetic energy of rotation movement to pressure. Axial flow water pump is single stage type commonly, individual pairs of class type.

brand pump axial flow pump in accordance with the pump shaft installation position can be divided into the type and level of a few kinds of column, side. Between them only pump shell method is different, have the similar structure. In our country, production, processing and manufacturing more is pillar type axial flow pump.

the three defect of axial flow pump is:

1, self-priming ability to run co. , LTD.

2, single-stage pump head is low;

3, high efficiency curve steeper and high efficiency area relatively narrow, if it weren't for the centrifugal impeller leaves placed Angle adjustment machine equipment, when poor runtime rationalization deviate from the design load.

because of the axial flow pump has three drawbacks, so we are in the process of the application of axial flow pump, there are six considerations have to produce net value.

1, the test run, check the connection position, make sure all the connection position not loose condition.

2, electronics, instruments all normal operation; Oil, gas, road, waterway of each subsystem can not have leakage; All pressure, hydraulic pressure is normal.

3, often check feed line nearby have suspended solids, prevent the inlet pipe blockage.

4, axial flow pump of the rolling bearing temperature should not be higher than 75 degrees.

5, pay attention to the voice of the water pump and vibration conditions at any time, an exception to stop the machine immediately to check.

6, the gear box oil temperature should be normal.
