Axial flow pump will have what problem?

axial flow pump by the rotating impeller blades produce liquid along the axis direction of the force to liquid conveying pump, improper use, maintenance or incorrect, may affect the normal use of axial flow water pump, even fail, so what are the common faults in general? How are we to do?

1, the appearance of axial flow pump is like a pipe, pump casing diameter and water inlet diameter, can be installed vertically ( Vertical) And horizontal installation ( Horizontal) , can also tilt installation ( Inclined type) 。 Basic parts including suction pipe, the impeller ( Including blades, wheel hub) , guide vane, pump shaft, water pipe, upper and lower bearings, packing box, and blade Angle adjusting mechanism, etc.

2, axial flow pump manufacturer after start there is no water or water yield little, may be submerged in the water depth of the impeller is not enough, we can deepen the depth; Axial flow pump impeller turning is not correct, to adjust the motor; Axial flow pump blade positioning pin fracture or blade is damaged, replace the blade positioning pin or blade at this time.

3, the use of a larger axial vibration, may be because the piping support instability, must tighten all bolts; May be a liquid with gas, carefully check each sealing surface of the water pump and inlet pipe road connecting bolt looseness ever, whether the gasket is damaged, water pump body and the piping system parts for damage; May be different heart pump and motor shaft, should be adjusted.

with the development of the society, axial flow pump has now been widely applied to low head and large discharge of occasions, such as irrigation, drainage, drainage canal, ship lock water level control, or used as a power plant large circulating pump. Lift higher axial flow pump ( When necessary into two stage) For shallow water jet propulsion of the ship.

is a must have for anyone who appreciates winter cover pump to the greatest extent.
