Features: 1, IH unipolar single suction centrifugal pump according to the international standard ISO2858 performance and size design, mainly by the pump body, pump cover, impeller, shaft, seal ring, bushings and suspension bearings missing and so on. 2, IH type unipolar single suction centrifugal pump body and pump cover part, is split from the back of the impeller, which is commonly referred to as the rear door structure. The advantage is easy maintenance, maintenance pump body, suction line, exhaust pipe and motor, just remove the longer coupling intermediate coupling, you can exit the rotor part of the overhaul. 3, the pump housing (ie, pump body and pump cover) constitute the pump studio. Impeller, shaft and rolling bearings for the pump rotor. The suspension bearing part supports the rotor part of the pump, which is subjected to the radial and axial forces of the pump. 4, in order to balance the pump axial force, most of the impeller pump impeller front and rear are equipped with a seal ring, and in the impeller rear cover with a balance hole, due to some pump axial force is not large, no seal on the back of the impeller Ring and balance hole. 5, the pump axial seal ring by the packing gland, packing rings and packing and other components to prevent air or large water leakage. If the pump impeller is balanced, the cavity filled with soft packing communicates with the suction inlet 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, so the packing ring is filled in the packing chamber Small holes in the pump cover lead the pressurized water in the pump chamber to the packing ring for sealing. Pump impeller, such as no balance hole, because the liquid pressure on the back of the impeller is greater than atmospheric pressure, so there is no leakage problem, it can not fill rings. 6, in order to avoid shaft wear, the shaft through the packing chamber parts with shaft sleeve protection. There is an O-ring between sleeve and shaft to prevent air ingress or leakage along mating surfaces. 7, the pump drive is coupled with the motor by extending the length of the flexible coupling, the direction of rotation of the pump, from the drive end, for clockwise rotation. Uses: IH unipolar single-suction centrifugal pump for petrochemical, pharmaceutical, food, textile, machinery, chemical, metallurgical, power, paper, environmental protection, wastewater treatment and synthetic fiber industries for the transmission of a variety of corrosion or not allowed Contaminated medium similar to water.
