D, DF, DY, MD-type pump horizontal, single-suction, multi-stage multi-stage centrifugal pump, suction port for the horizontal direction, the vertical exit for the outlet. Pump part of the water, the middle, the water section of the pump part of the pump through the tightening bolts connected into one, and according to the pump head to select the pump series.
The series of pump rotor part of the main by the installation and the shaft of the impeller, sleeve, balance plate and other components, including the number of impellers according to the pump series. The shaft parts are fastened with a flat key and a shaft nut to fit the shaft. The entire rotor is supported by both ends of the rolling bearing or sliding bearing. Bearings according to different models, do not bear the axial force, the axial force balance by the balance plate.
The sealing surface between the inlet section, the middle section and the effluent section of the pump is sealed with a sealant or an O-ring. The sealing ring and the guide vane cover are sealed between the rotor part and the fixed part. When the sealing ring and guide vane The degree of wear of the sleeve has affected the performance of the pump and should be replaced.
Shaft seal in the form of mechanical seal and packing seal two. When the pump is sealed with the packing, the position of the packing ring is placed correctly, and the tightness of the packing must be appropriate. It is advisable for the liquid to drop one by one. Pump of various sealing elements installed in the sealed cavity, the cavity to pass a certain pressure of water, water seal, water or water lubrication role. A replaceable sleeve is provided at the shaft seal to protect the pump shaft.
(D85-67, D155-67 type pump can be used for sliding bearings, thin oil lubrication structure, can also be used to roll bearings, the use of rolling bearings, , Dry oil lubrication structure).
