IS type single-stage clean water centrifugal pump application range
      The IS type single-stage clear water centrifugal pump is a nationally designed energy-saving pump. It is an updated version of the BA type, B type and other single-stage clean water centrifugal pumps. The advantages are as follows: the whole series of hydraulic performance layout is reasonable, the user has a wide selection range, and the maintenance is convenient; the efficiency and the suction stroke reach the international average advanced level. IS type single-stage clear water centrifugal pump is suitable for industrial and urban water supply and drainage. It can also be used for agricultural drainage and for the transportation of clean water or other liquids with physical and chemical properties similar to clean water. The temperature is not higher than 80 °C.
IS type single-stage clear water centrifugal pump product features
1. IS type single-stage clean water centrifugal pump is designed according to the performance and size specified by international standard ISO2858. It is mainly composed of pump body, pump cover, impeller, shaft, seal ring, bushing and suspension bearing.
2. The pump body and pump cover part of the IS type single-stage clean water centrifugal pump are divided from the back of the impeller, which is commonly referred to as the rear open door structure. The utility model has the advantages that the maintenance is convenient, the pump body is not moved during the maintenance, the suction pipeline, the discharge pipeline and the electric motor are removed, and only the intermediate coupling member of the extension coupling is removed, and the rotor portion can be taken out for maintenance.
3. The housing of the IS type single-stage clean water centrifugal pump (ie pump body and pump cover) constitutes the working chamber of the water pump. The impeller, shaft and rolling bearing are the rotor of the pump. The suspension bearing component supports the rotor portion of the pump, which is subjected to the radial and axial forces of the pump.
4. IS type single-stage clean water centrifugal pump In order to balance the axial force of the pump, most of the pump impellers are provided with a sealing ring before and after, and a balance hole is arranged on the rear cover of the impeller. Large, there is no seal ring and balance hole on the back of the impeller.
5. The axial seal ring of the IS type single-stage clean water centrifugal pump is composed of a packing gland, a packing ring and a packing to prevent intake air or a large amount of water leakage. If the impeller of the pump is balanced, the cavity with the soft packing is connected to the suction port of the impeller. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to enter the air along the surface of the sleeve. Therefore, a packing ring is inserted in the filling chamber. A small hole in the pump cover guides the pressure water in the clean water centrifugal pump chamber to the packing ring for sealing. If there is no balance hole in the impeller of the pump, since the liquid pressure on the back of the impeller is greater than atmospheric pressure, there is no gas leakage problem, so the packing ring may not be installed.
6. Single-stage clean water centrifugal pump is equipped with bushing protection in the part of the shaft passing through the packing cavity to avoid shaft wear. An O-ring seal is provided between the sleeve and the shaft to prevent air intake or water leakage along the mating surface.
7. The transmission mode of the single-stage clean water centrifugal pump is connected with the electric motor by lengthening the elastic coupling. The rotation direction of the pump is rotated clockwise from the driving end.
Model meaning of IS type single-stage clear water centrifugal pump

IS type single stage centrifugal pump structure description
      The IS type single-stage centrifugal pump conforms to the national standard GB5662-85 equivalent to the marking performance and size specified by the international standard ISO2858. It is mainly composed of pump body, pump cover, impeller, shaft, seal ring, bushing and suspension bearing components. The housing of the IS type single stage centrifugal pump (ie the pump body and the pump cover) constitutes the working chamber of the pump. The impeller, shaft, and rolling bearings of the Yangzijiang pump industry are the rotors of the pump. The suspension bearing component supports the rotor component of the pump, and the rolling bearing is subjected to the radial and axial forces of the pump. In order to balance the axial force of the pump, most pumps have no seal ring in front of and behind the impeller, and a balance hole is provided on the rear cover of the impeller. The axial seal of the clear water centrifugal pump is in the form of soft packing seal, mechanical seal and rubber oil seal. The rotation mode of the clear water centrifugal pump is coupled to the motor through the elastic coupling, and the pump rotates clockwise from the driving end.
