ALIGNMENT METHOD FOR ROTOR PUMP WITH RESPECT TO HOUSING DURING average repair the main pump units

摘要

Method pump rotor alignment relative to the body during the secondary repair of the main pump unit in which is carried a replacement of the mechanical seal, which consists in that mounted on the seat face seals calibrated devices in a sleeve, which is formed with an inside diameter to fit onto the rotor shaft in the installation site face seal and an outer diameter providing a guaranteed gap with an inner bore diameter of the mechanical seal chamber, collect ku plain bearings and packet angular contact bearing, the clearance is measured along the diameter devices on both sides and eliminate the misalignment by adjusting the position of the shaft relative to the axis of the chamber by moving the front and rear sliding bearings via nip bolts.
