'', horizontal multi-stage centrifugal pump product overview:
'', horizontal multi-stage pump series single-suction multi-stage segmented horizontal centrifugal pump, which is the latest version of the old product Based on the pump, it boldly improves the mechanism and uses advanced hydraulic models to design high-efficiency and energy-saving updated products. All of them replace the old pumps. According to the input medium and temperature, a series of pumps are derived.

Structural features of the horizontal multi-stage pump:
: -: '' The inlet and outlet of the pump are vertically upward, and they are tightened by tightening the bolts. The water inlet section, middle section, water outlet section, bearing body and other pump housing parts of the pump are connected into one body. Select the number of pump stages based on the pump head. The rotor part of this series of pumps is mainly composed of a shaft and impellers, bushings, balance plates and other parts installed on the shaft. The number of impellers depends on the number of stages of the pump. The parts on the shaft are fastened with flat keys and shaft nuts to integrate them with the shaft. The entire rotor is supported by rolling bearings or sliding bearings at both ends. The bearings vary according to model and do not bear axial force. The axial force is balanced by the balance plate. During operation of the pump, the rotor is allowed to move axially in the pump casing, and radial ball bearings cannot be used. The rolling bearings are lubricated with grease, the sliding bearings are lubricated with thin oil, and are white lubricated with oil rings, and cooled by circulating water. The sealing surfaces between the inlet section, middle section and outlet section of the pump are all sealed with molybdenum disulfide grease. A sealing ring, guide vane sleeve, etc. are installed between the rotor part and the fixed part for sealing. When the sealing ring and guide vane sleeve When the degree of wear has affected the working performance of the pump, it should be replaced. There are two types of sealing: mechanical seal and packing seal. When the pump is sealed with packing, the position of the packing ring must be correct, and the tightness of the packing must be appropriate so that the liquid can seep out drop by drop. Various sealing components of the pump are installed in a sealed box, and water at a certain pressure must be introduced into the box to function as water seal, water cooling or water lubrication. A replaceable shaft sleeve is installed at the shaft seal to protect the pump shaft.
: -: '' Sub-high pressure pumps generally use sliding bearings and thin oil lubrication structures. - and - type pumps can use sliding bearings and thin oil lubrication structures, or rolling bearings and dry oil lubrication structures. The other models all use sliding bearings and thin oil lubrication structures. Rolling bearing, dry oil lubrication structure. The main parts of medium and low pressure pumps are generally made of high-quality cast iron, and the main parts of sub-high pressure pumps are made of cast steel or stainless steel. This series of pumps are directly driven by the prime mover through an elastic coupling. Viewed from the direction of the prime mover, the pump rotates clockwise
