The centrifugal pump single stage also includes a wafer coupling disposed between the motor output shaft and the pump shaft, and a guide bearing installed on the bearing seat to assist in supporting the pump shaft; the wafer couplings are respectively connected with The motor output shaft and the pump shaft are rigidly connected, and a space distance is left between the motor output shaft and the pump shaft to facilitate the assembly and disassembly of the mechanical seal and the mechanical seal gland. When repairing or replacing the mechanical seal, it is not necessary to remove the motor and pump cover.
The transmission mode of centrifugal pump single stage is to connect with the motor by lengthening the elastic coupling. The rotation direction of the pump, viewed from the driving end, is clockwise.
In order to avoid shaft wear, a shaft sleeve is installed to protect the shaft passing through the packing cavity. There must be an O-ring between the sleeve and the shaft to prevent air intake or water leakage along the mating surface.
Centrifugal pump single stage is mainly suitable for industry and agriculture and urban, drainage, fire water supply, etc.
