Mine Drainage Horizontal Multistage Centrifugal Pump

Mine drainage horizontal multistage description:

Mine drainage horizontal multistage centrifugal pump is a horizontal single-suction multistage centrifugal pump, which adopts the hydraulic model of high efficiency and energy saving products recommended by the state, and occupies an advanced position in the industry. It has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long life, easy installation and maintenance, etc.

Model implication:

MD155-67x9
MD - is a multistage centrifugal pump for mining
155 - The design point flow of the pump is 155m3/h
67 - is the pump single-stage design point lift of 67m
9 - is the pump stage of 9

Mine drainage horizontal multistage centrifugal pump is used for transporting neutral mineral water with solid particle content not more than 1.5% (particle size less than 0.5 mm) and similar other sewage, the temperature of the conveying medium is not more than 80℃, suitable for steel works, mine drainage, sewage transportation and other occasions.

The rotor part of Mine drainage horizontal multistage centrifugal pump is mainly composed of shaft and impeller, shaft sleeve, balance plate and other parts installed on the shaft, the number of impeller is determined according to the pump series. The parts on the shaft are fastened by flat keys and shaft nuts so that they are integrated with the shaft. The whole rotor is supported by both ends of the rolling bearings or plain bearings, bearings depending on the model, are not subjected to axial force, its axial force is balanced by the balance plate. The pump allows the rotor to travel axially in the pump housing during operation, and the centripetal ball bearing cannot be used. Rolling bearings are lubricated with grease, sliding bearings are lubricated with thin oil, and oil rings are self-lubricated and cooled by circulating water. The sealing surface between the inlet section, the middle section and the outlet section of the pump are sealed with molybdenum disulfide grease, and the sealing ring and guide vane sleeve are installed between the rotor part and the fixed part. When the wear degree of the sealing ring and guide vane sleeve has affected the working performance of the pump, it should be replaced.

The sealing form Mine drainage horizontal multistage centrifugal pump has two kinds: mechanical seal and packing seal. When the pump uses the packing seal, the position of the packing ring should be placed correctly, the tightness of the packing must be appropriate, and the liquid can leak out drop by drop. Various sealing components of the pump are installed in the sealing chamber, and a certain pressure of water should be passed into the chamber, and the water seal, water cooling or water lubrication should be allowed. A replaceable sleeve is installed at the shaft seal to protect the pump shaft.

The rotation direction of this type of mine drainage horizontal multistage centrifugal pump is clockwise from the direction of the original motor.
