Dry screw vacuum pump axial gap how to adjust

Hangzhou xinanjiang industrial pump co., LTD. To tell you: dry screw vacuum pump radial clearance how to adjust it? The centrifugal impeller is mounted on the screw vacuum pump shaft, and then the front and rear side covers are installed to adjust the radial clearance:

1, screw vacuum pump down hard up, on the bracket, pump shaft, make one side cover is supported on the bracket, screw vacuum pump against the force of centrifugal impeller is strong point on the side of the cover, the centrifugal impeller and the other side of the cover, the radial clearance between the screw vacuum pump radial clearance on both sides together, the total clearance can be measured by the following method

2, the dial meter table seat on the side cover, dial and screw vacuum pump shaft top touch screen, and adjust to zero, then change the lever pry pump shaft tail, pry centrifugal impeller and the above side cover all contact, then the dial meter marked number for the total radial clearance. If the total radial clearance exceeds the standard value, adjust it appropriately

3. After the total radial clearance reaches the standard, after all parts of the screw vacuum pump are processed, the radial clearance at both ends can be evenly distributed by rotating the shaft sleeve nut, pushing the centrifugal impeller to move on the shaft, and pushing the centrifugal impeller so that there is no dispute between the centrifugal impeller and the side cover. Of course, this adjustment method does not guarantee that the radial clearance at both ends is exactly the same as the year-on-year growth rate
