Centrifugal pumps operate by causing water to move centrifugally as a result of the rotation of an impeller. Before the water pump is started, the pump shell and the water suction pipe are filled with water, then the motor is started, the pump shaft drives the impeller and the water to rotate at a high speed, the water is thrown to the outer edge of the impeller to be thrown into a water pressure pipeline of the water pump through a flow channel of the volute-shaped pump shell.
The pump shaft and the motor shaft of the existing fluoroplastic-lined chemical centrifugal pump are fixed through bolts, the pump shaft and the motor shaft are closely matched by utilizing the principle of Morse taper, and the pump shaft and the motor shaft are in the following defects by adopting the mode:
1. firstly, the Morse taper is processed at the tail end of the pump shaft, then the motor is disassembled, a hole corresponding to the Morse taper is processed at the tail end of the motor shaft, and the motor shaft and the pump shaft are connected through the bolt, so that the labor intensity is high, and the production efficiency is reduced.
2. Adopt closely to cooperate between motor shaft and the pump shaft, though utilize frictional force's principle, can transmit certain moment of torsion, but when dismantling, the pump shaft is very difficult to drop from the motor shaft in, and it is very inconvenient to dismantle.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model aims at providing a high accuracy transmission that can dismantle fast.
