1. The multi-stage submersible pump product is a vertical single-suction multi-suction segmented centrifugal pump. The suction inlet of the DLY type pump is at the bottom and vertically downward, and the center of the discharge outlet is arranged horizontally.This series of pumps have the advantages of small size, small floor space, low noise, no radial force generated when the radial guide vanes are running, stable operation, high efficiency, and few exposed parts.2. Multi-stage submersible pump transmission The multi-stage submersible pump is driven by an outdoor vertical explosion-proof motor installed on the motor frame through a coupling. The pump rotates counterclockwise when viewed from the motor end.3. Multi-stage submersible pump shaft seal The multi-stage submersible pump adopts a packing seal with a shaft outlet structure in the low-pressure area, which is safe, reliable and does not leak.4. Multi-stage submersible pump bearings and balancing device. The upper part of the pump shaft is supported by a double-row radial thrust ball bearing. The lower part of the pump shaft is supported by a wear-resistant alloy sliding bearing. The axial force of the pump is balanced by a balance drum or balance hole. The residual axial force is borne by the upper bearing.The upper bearing is lubricated with grease or thin oil, and the sliding bearing is lubricated by the transported medium.5. The material of the multi-stage submersible pump can be selected according to the different media of the user, such as ductile iron QT600-3, stainless steel 1Cr18Ni9Ti or cast iron HT200.
