Prior art vertical mult...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the complex structure of the prior art vertical multistage pump, there are many parts, cumbersome machining, troublesome assembly, and it is not easy to meet the design requirements. Rework is often required, which is time-consuming and labor-intensive, and the labor intensity of the workers is high.

[0004] 2. The impeller, the heart part of the vertical multi-stage pump in the prior art, especially the impeller with a narrow flow path, is difficult to remove sand, and there is sticky sand in the flow path which is not smooth, which reduces the hydraulic efficiency of the pump and increases the power of the matching motor. Large energy loss

[0005] 3. The other parts of the prior art vertical multi-stage pump are made of cast iron, which has poor mechanical properties. In order to meet the requirements of design strength, the cast iron has a large wall thickness, which makes the cast iron very heavy and causes Waste of materials, pollution to the environment when manufacturing iron castings

[0006] 4. The appearance of the prior art vertical multistage pump is rough, the whole machine is heavy, and the transportation and installation are inconvenient

[0007] 5. The vertical multi-stage pump in the prior art adopts bottom-in and top-out water inlet and drainage, which requires the outlet pipeline to be raised or installed with auxiliary facilities such as elbows, which is very inconvenient to install and use.

[0008] 6. Due to the use of a set of rolling bearings in the prior art vertical multi-stage pump, in order to prevent the bearings from dry grinding, generating noise and damaging the bearings, it is necessary to add grease regularly, which increases the maintenance cost

[0009] 7. The prior art vertical multi-stage pump adopts the early hydraulic model, and the hand-made model and manual modeling in the casting process make the casting deviate from the drawing, and the design requirements cannot be fully guaranteed. The smoothness of the flow channel is poor, and the hydraulic loss is large. Overall efficiency is low

The guide vanes are separated from the middle section, increasing the processing steps, and there are errors in the processing, which cannot effectively guarantee the axial dimension requirements, especially for pumps with many stages.

[0010] 8. The prior art vertical multistage pump adopts packing seal, the sealing effect is poor, the time is short, and it needs to be replaced regularly

In order to prevent the packing from being rough, it will rub against the pump shaft at high speed and heat up, and the pump shaft will be locked. There must be a certain leakage at the packing seal, which will cause pollution to the external environment.

[0011] 9. The prior art vertical multistage pump adopts the balance drum method to balance the axial force. This method cannot completely balance the axial force, and the bearing components are required to bear a small part, which reduces the service life of the bearing.

[0012] 10. The prior art vertical multistage pump is equipped with an ordinary Y series motor, which is air-cooled. When the motor rotates, it drives the upper fan to rotate at a high speed to cool the motor. As the power of the motor increases, the noise generated by the fan also big
