How to adjust the axial channeling of multistage pump?
The adjustment should be toward the end of the pump rotor is pushed to the bottom, can not push, then the balance disk or blade ring at the step up (according to figure), then marked on the shaft and started to pull out of the rotor, with the distance can be calculated when the balance disc space, after the installation of the bearing.
The axial thrust of the multistage centrifugal pump is adjusted to meet the requirements of the clearance of the balance disc in the drawing, so that the pump works under the design of axial force.
Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work. The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.
