Common faults of vertical axial flow pumps include problems such as no or low water output after startup, large vibration or noise, sudden rise or low current, and high temperature of the bearing housing. What are the reasons why these problems occur for drainage pump manufacturers , and what methods should be used to solve them? Today, I will introduce them in detail:

The treatment method of no water or low water output after starting the vertical axial flow pump : the impeller submerged depth is insufficient, the treatment method is to adjust the impeller submergence depth; the impeller is not turned correctly, the treatment method is to adjust the motor steering; the blade is damaged or the blade positioning pin is broken, deal with The method is to replace the blades or positioning pins; the pump inlet or the impeller is blocked by debris, and the treatment method is to remove debris; the pump shaft is detached, and the treatment method is to reassemble or replace the pump shaft.

Vertical axial flow pump is a vane pump. This pump has the characteristics of large flow, low head, high specific speed, high efficiency, small footprint, variable performance parameters, and suitable for low water conditions. Therefore, it often becomes the preferred pump type for agricultural drainage and irrigation, urban water supply and drainage, and circulating power transmission in thermal power plants. The vertical axial flow pump draws water from the pool through the suction horn tube. Because the blades of the impeller in the impeller force the water to rotate, the water enters the guide vane, and the energy is converted to generate a lift. discharge. The pump is coupled to the intermediate shaft via a coupling (rigid). The bearing under the motor support bears all the downward axial force of the rotor. The intermediate shaft and the motor shaft are connected with an elastic coupling.

At present, with the continuous progress of China's science and technology, vertical, horizontal, inclined and cross-flow axial flow pumps have been developed. Today, I will introduce the conditions for the trial operation of vertical axial flow pumps:

1. The civil engineering of the vertical axial flow pump station has been basically completed, and the water level of the inlet and outlet pools and the amount of incoming water have all met the requirements for the trial operation of the pump station.

2. The main engine group and auxiliary equipment have been installed, and the relevant shut-off devices such as working gates, maintenance gates, and gate hoisting equipment have also been installed, and they have passed the acceptance inspection of the branch project, which can meet the test operation requirements of the pumping station.

3. The power supply of the pumping station is indeed guaranteed. The power supply lines and substations have passed the acceptance check. The trial operation power plan has been implemented.

4. The fire protection system of the vertical axial pump pump station has passed inspection and acceptance, and the fire fighting equipment is complete and in place.
