Technical Field
The invention relates to the technical field of centrifugal pumps, in particular to a vertical stainless steel multistage centrifugal pump.
Background
The centrifugal pump works by utilizing the centrifugal motion of water generated by the rotation of an impeller, before the water pump is started, a pump shell and a water suction pipe are filled with water, then a motor is started, a pump shaft drives the impeller and the water to rotate at a high speed, the water generates the centrifugal motion and is thrown to the outer edge of the impeller and flows into a water pressing pipeline of the water pump through a flow channel of a volute-shaped pump shell,
however, in the prior art, the impeller of the neutral stainless steel multistage centrifugal pump is mostly installed on the main shaft through bolts, and during installation, the bolts need to be continuously screwed down by means of tools, so that the installation is time-consuming and labor-consuming.
Disclosure of Invention
Technical problem to be solved
