Four common failure causes and solutions of axial flow pump

axial flow forming problem what should I do? For does not affect the normal application of axial flow pump, should actively seek out problems, timely solve the problem.

problem phenomenon: pump overload

1, leaf placed right Angle; Solution: to adjust the blade Angle is placed

2, operation point deviates from the design point; Solution: adjust the operate in the allowed range

3, speed is above; Solution: check the reason, adjust the motor speed

4, cylindrical blade friction with the impeller chamber; Solution: adjust the clearance, check whether the rubber bearing damaged

5, leaf or trash rack around with dirt; Solution: remove dirt

6, head is too high, the water pipe jam, discharge valve has been fully; Solution: remove the dirt, open

7, too tightly on the packing; Solution: appropriate to relax the packing gland

8, two-phase motor operation; Solution: check the power supply situation, wiring of

phenomenon of problem 2: abnormal noise vibration

1, the inlet into the gas formation of cavitation; Solution: ascending into water

2, basic imperfect water pump and motor shaft with different heart pump shaft or the shaft bending; Solution: foundation reinforcement, reinstall the correction, will drive shaft straightening

3, rotor residual unbalance weight; Solution: remove the rotor balance school again

4, guide bearing or seriously damaged shaft sleeve, and rolling bearing damage failure; Solution: changing a guide bearing or sleeve, changing a rolling bearing

5, blade local obstruction or damage to the blade; Solution: remove dirt or changing a blade

6, loose anchor bolt; Solution: check and reinforce

7, various fasteners, drive a nut loose or basic weak; Solution: check and tighten the fasteners, bolts, reinforcing basic

8, within a few water pump assembly in the same pool are lined up unreasonable interference; Solution: inside into the pool, add a baffle between pump

9, into the water level is too low, too little impeller cover depth; Solution: reduce the assembly height or ascend into water

three problem phenomenon: lack of traffic

1, blade assembly Angle is too small; Solution: adjust the blade assembly Angle again

2, speed yet rating; Solution: to eliminate the prime mover problem

3, cylindrical blades damage and damage to the blade; Solution: changing a blade

4, head high; Solution: to find a way to adjust the head, check the water pipe have blocked

5, vane, guide vane, or around on the trash rack has dirt; Solution: remove dirt

problem phenomenon 4: no water

1, pump being optional location is wrong; Solution: adjust the engine rotating bearing

2, fixed blade failure; Solution: check the blade, impeller positioning device, to adjust the Angle of blade assembly again

3, into a lot of gas suction nozzle; Solution: ascending into water

4, suction clogged; Solution: remove dirt suction

5, the export type suction a rainbow, height is too high; Solution: reduce the height.
