D Type Series Horizontal Multistage Centrifugal Pump
 

D-Series Multistage Centrifugal Pumps Overview
     The D-series multi-stage centrifugal pump is a single-suction multi-stage centrifugal pump for conveying water and liquids with physical and chemical properties similar to water. The pump head has a head of H23 to 153.6 meters and a flow rate of 12.6--39.6 m3/h. The high temperature of the liquid must not exceed 80 ° C.

D type series multistage centrifugal pump model meaning

D-series multi-stage centrifugal pump product structure description

      The D-series multi-stage centrifugal pump is multi-stage segmented type. The suction port is located on the inlet section and is horizontal, and the discharge port is vertically upward on the water section. The lift head can increase or decrease the number of pump stages according to the needs of use. Whether the pump is assembled well or not has a great influence on the performance, especially the outlet of each impeller and the entrance and exit center of the guide vane. The slight deviation will reduce the flow of the pump and the efficiency of the lift will be poor. Therefore, it is necessary to pay attention to the inspection and assembly. .

      The main components of the D-type multi-stage centrifugal pump are: inlet section, middle section, outlet section, impeller, guide vane flap, outlet section guide vane, shaft, seal ring, balance ring, bushing, tail cap and bearing body. The inlet section, the middle section, the vane baffle, the outlet section guide vane, the outlet section and the tail cap are all made of cast iron, which together form the working chamber of the pump. The impeller is made of high-quality cast iron, with blades inside, and the liquid enters in one side in the axial direction. Because the impeller is subjected to different pressures before and after, there is bound to be an axial force. This axial force is borne by the balance disc, and the static balance test is carried out during the manufacture of the impeller. . The shaft is made of high-quality carbon steel with an impeller in the middle and is fixed to the shaft with a key, bushing and bushing nut. One end of the shaft is fitted with a coupling member that is directly connected to the motor. The sealing ring is made of cast iron to prevent the high-pressure water of the pump from leaking back into the water inlet part, and is fixed on the water inlet section and the middle section respectively, which is a wearing part, and can be replaced by Spare Parts after being worn. The balance ring is made of cast iron and is fixed on the water outlet section. It is combined with the balance to form a balancing device. The balance disc is made of wear-resistant cast iron and is mounted on the shaft between the water outlet section and the tail cover to balance the axial force. The bushing is made of cast iron and is located at the packing chamber. It is used as a fixed impeller and protects the pump shaft. It is a wearing part and can be replaced with spare parts after wear. The bearings are single row radial ball bearings lubricated with calcium based grease. The packing acts as a seal to prevent air from entering and a large amount of liquid from leaking out. The packing seal is composed of a packing chamber on the inlet section and the tail cap, a packing gland, a packing ring and a packing, and a small amount of high-pressure water flows into the packing chamber to function as a water seal. The tightness of the packing must be appropriate, not too tight or too loose, and the liquid can be oozing one drop at a time. If the packing is too tight, the sleeve is prone to heat and consumes power. The packing is too loose and the efficiency of the pump is reduced due to fluid loss.

D type series multi-stage centrifugal pump product features

1. Advanced hydraulic model, high efficiency and wide performance range.

2. The pump runs smoothly and the noise is low.

3. The shaft seal adopts soft packing seal or mechanical seal. The seal is safe and reliable, the structure is simple, and the maintenance is convenient and quick.

4. The shaft is a full-sealed structure, ensuring that it does not come into contact with the medium, does not rust, and has a long service life.
