IS type single-stage clear water centrifugal pump | horizontal centrifugal pump | application range of air conditioning circulating pump

The IS type single-stage clear water centrifugal pump is an energy-saving pump jointly designed by the whole country. It is an updated version of the BA type, B type, and other single-stage clear water centrifugal pumps. Advantages include: reasonable layout of hydraulic performance across the entire series, wide range of user choices, and convenient maintenance; Efficiency and suction reach the international average advanced level. The IS type single-stage clear water centrifugal pump is suitable for industrial and urban water supply and drainage, as well as agricultural irrigation and transportation of clear water or other liquids with physical and chemical properties similar to clear water, with a temperature not exceeding 80 ℃.

1. The centrifugal pump system is designed according to the performance and dimensions specified in the international standard ISO2858, mainly consisting of the pump body, pump cover, impeller, shaft, sealing ring, shaft sleeve, and suspension bearings.
2. The pump body and pump cover of a centrifugal pump are divided from the back of the impeller, commonly known as the rear opening structure. Its advantage is easy maintenance. During maintenance, the pump body, suction pipeline, discharge pipeline, and motor are not moved. Only the middle connecting piece of the extended coupling needs to be removed to exit the rotor part for maintenance.
3. The casing (i.e. pump body and pump cover) of a centrifugal pump constitutes the working chamber of the water pump. The impeller, shaft, and rolling bearings are the rotors of the pump. The suspension bearing components support the rotor part of the pump, while the rolling bearings are subjected to the radial and axial forces of the pump.
4. In order to balance the axial force of centrifugal pumps, most pumps are equipped with sealing rings in front and behind the impeller, and balance holes are provided on the rear cover plate of the impeller. Due to the low axial force of some pumps, there are no sealing rings or balance holes on the back of the impeller.
5. The axial sealing ring of a centrifugal pump is composed of a packing gland, packing ring, and packing to prevent air intake or significant water leakage. If the impeller of the pump is balanced, the cavity containing 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 introduce air along the surface of the shaft sleeve. Therefore, a packing ring is installed in the packing chamber through the small hole on the pump cover to guide the pressure water in the centrifugal pump chamber to the packing ring for sealing. If the impeller of the pump does not have a balance hole, there is no leakage problem due to the liquid pressure on the back of the impeller being greater than atmospheric pressure, so the packing ring can be omitted.
6. A single-stage centrifugal pump for clean water is equipped with a shaft sleeve protection at the part where the shaft passes through the packing chamber to avoid shaft wear. There is an O-ring seal between the shaft sleeve and the shaft to prevent air intake or water leakage along the mating surface.
7. The transmission method of a single-stage clear water centrifugal pump is connected to an electric motor through an extended elastic coupling. The rotation direction of the pump, when viewed from the drive end, is clockwise.

IS type single-stage clear water centrifugal pump | horizontal centrifugal pump | air conditioning circulating pumpStructural Description

The IS type single-stage clear water centrifugal pump complies with the marking performance and dimensions specified in the national standard GB5662-85 equivalent to the international standard ISO2858. It is mainly composed of pump body, pump cover, impeller, shaft, sealing ring, shaft sleeve, and suspension bearing components.
The casing (i.e. pump body and pump cover) of the IS type single-stage clear water centrifugal pump constitutes the working chamber of the pump. The impeller, shaft, and rolling bearings of the western pump valve are the rotors of the pump. The suspension bearing components support the rotor components of the pump, while the rolling bearings bear the radial and axial forces of the pump.
In order to balance the axial force of the pump, most pumps do not have sealing rings in front and behind the impeller, and there are balance holes on the cover plate behind the impeller.
The axial seal of a clear water centrifugal pump can be in three forms: soft packing seal, mechanical seal, and rubber oil seal.
The rotation mode of the clear water centrifugal pump is connected to the motor through an elastic coupling. From the driving end, the pump rotates clockwise.
