IS-type centrifugal pump centrifugal Scope of application:
IS-type centrifugal pump water for industrial and urban water supply and drainage, can also be used for irrigation and drainage. For the transport of water or other physical and chemical properties similar to the use of water, the transmission medium temperature is not higher than 80 ℃.
IS Type Centrifugal Pump Description of Structure: The
IS / CIS type pump is designed according to the performance and size stipulated by international standard ISP2858. It is mainly composed of pump body, pump cover, impeller, shaft sealing ring, shaft sleeve, mechanical seal and suspension bearing Not seen and so composed.
IS / CIS-type pump pump body and pump cover part, is split from the back of the impeller, the so-called 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 parts for overhaul.
Pump housing (ie, pump body and pump cover) constitute the pump studio. Impeller, shaft and rolling bearings are the rotor of the pump. The suspension bearing part supports the rotor part of the pump. The rolling bearing withstands the radial and axial force of the pump.
In order to balance the axial force of the pump, most of the pump impeller front and rear are provided with a seal ring, and the impeller rear cover with a balance hole. Due to the small axial force of some pumps, there is no seal ring and balance hole on the back of the impeller.
IS-type pump axial seal packing seal, packing gland packing ring and packing.
CIS-type pump axial seal with a mechanical seal, reducing the amount of leakage pump.
If the pump impeller balance hole, then filled with soft filler cavity and the impeller suction port connected, if the impeller inlet liquid is in a vacuum state, it is easy to intake along the sleeve surface, it is filled with filler ring, Through the hole in the shaft cover, lead the pressure 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. To avoid shaft wear, the shaft is protected by a bushing at the area where the shaft passes through the packing chamber with an O-ring between the bushing and the shaft to prevent ingress or leakage of water along the mating surfaces.
Pump drive by extending the length of flexible coupling with the motor. Pump rotation direction, from the drive end, clockwise rotation.
