The clean water centrifugal pump were open for distribution of water and Physics,Chemical substances similar to those of liquid water. The series pump widely used to industry,agriculture,city drainage and fire water etc. The centrifugal pump's performance and design size that according to international standard IS02858. The technology standard reach international standard.
Seven structure specialty of clean water centrifugal pump:
- The centrifugal pump's performance and design size that according to international standard IS02858. The pump main made of body of pump, pump cover , impeller, shaft , seal ring, shaft sleeve, shaft bearing and others.
- The body and cover of pump that separate from back of impeller. The feature that is convenient maintenance. When maintence that the middle of the lengthened coupling connection should be remove and exit the part of rotor and others keep original.
- The shell(body and cover of pump) made of work room of pump. The rotor be made of impeller ,shft and antifriction etc. The suspension bearing part supports the rotor of the pump, and the radial force and axial force of the rolling bearing are affected by the pump.
- In order to axial force, before and after impeller have seal ring for most of pump. And has a balance hole in the impeller hub, the axial force of pump impeller back some small, no sealing ring and balance hole.
- The axial sealing ring of pump be made of the packing gland,packing ring and packing etc. In order to prevent input air and outlet water. If the pump impeller balance is equipped with soft packing of the cavity and impeller suction port connected, such as the liquid in the impeller inlet is in a vacuum state, it is very easy to along the surface of sleeve inlet, so in packing chamber with packing ring through the hole in the pump cover, the centrifugal water pump room pressure water lead to ring packing seal. If there is no balance hole of the impeller of the pump, the liquid pressure on the back side of the impeller is greater than the atmospheric pressure, so there is no leakage problem, therefore, the packing ring can not be filled.
- In order to avoid shaft broken, shaft axial protect the packing chamber when shaft according.A quasi O type sealing ring between the shaft sleeve and the shaft, along with the surface to prevent intake or Water Leakage.
- The transmission mode of the water centrifugal pump is connected with the electric motor through a lengthened elastic coupling, and the rotation direction of the pump is seen from the driving end, and is rotated in a clockwise direction.
