This itemHorizontal multi-stage centrifugal pumpAdvantage
1. The hydraulic model is advanced, efficient, and has a wide range of performance.
2Smooth operation with low noise.
3. The shaft seal adopts soft packing seal or mechanical seal, which is safe, reliable, structurally simple, and easy to maintain.
4. The shaft is a fully sealed structure, ensuring no contact with the medium, no corrosion, and a long service life.
D horizontal multi-stage centrifugal pumpSTRUCTURE DESCRIPTION
It is a multi-stage segmented design, with the suction port located on the inlet section in a horizontal direction, and the discharge port vertically upward on the water section. The head of the pump can be increased or decreased according to usage needs. Whether the water pump is well assembled or not has a significant impact on its performance, especially the outlet of each impeller and the inlet and outlet center of the guide vanes. Any slight deviation will reduce the flow rate and head of the water pump, resulting in poor efficiency. Therefore, attention must be paid during maintenance and assembly.
The main components of the D-type horizontal multi-stage centrifugal pump include: inlet section, middle section, outlet section, impeller, guide vane baffle, outlet section guide vane, shaft, sealing ring, balance ring, shaft sleeve, tail cover, and bearing body.
The inlet section, middle section, guide vane baffle, outlet guide wing, outlet section, and tail cover are all made of cast iron, forming the working chamber of the pump together.
The impeller is made of high-quality cast iron and has blades inside. The liquid enters on one side along the axial direction. Due to the unequal pressure on the impeller before and after, there must be axial force, which is borne by the balance plate. The impeller is manufactured through static balance testing.
The shaft is made of high-quality carbon steel, with an impeller installed in the middle, fixed on the shaft with keys, shaft sleeves, and shaft sleeve nuts. One end of the shaft is equipped with a coupling component, which is directly connected to the motor.
The sealing ring is made of cast iron to prevent high-pressure water from leaking back into the inlet section of the water pump. It is fixed on the inlet and middle sections respectively and is a vulnerable part. After wear, it can be replaced with spare parts.
The balance ring is made of cast iron and fixed on the outlet section. It forms a balance device together with the balance.
The balance plate is made of wear-resistant cast iron and is installed on the shaft, located between the water outlet section and the tail cover, to balance axial forces.
The shaft sleeve is made of cast iron and is located at the packing chamber. It is used to fix the impeller and protect the pump shaft. It is a vulnerable part and can be replaced with spare parts after wear.
The bearing is a single row radial ball bearing lubricated with calcium based grease.
The packing plays a sealing role, preventing air from entering and a large amount of liquid from leaking out. The packing seal consists of a packing chamber on the inlet section and tail cover, a packing gland, a packing ring, and packing, etc. A small amount of high-pressure water flows into the packing chamber to act as a water seal. The tightness of the filler must be appropriate, neither too tight nor too loose, based on the ability of the liquid to seep out drop by drop. If the packing is too tight, the shaft sleeve is prone to heating and consumes power. The packing is too loose, which reduces the efficiency of the water pump due to liquid loss.
