The centrifugal compressor is a high-speed rotating precision machine that is a combination of a high-speed rotating rotor and a fixed cylinder (chassis), usually driven by a motor or a steam turbine. Centrifugal compressors are characterized by high speed, high power and high price. The quality of the compressor operation is related to the large problem of whether the whole device can supply nitrogen normally. Therefore, in addition to careful operation and maintenance of the unit, its maintenance is particularly important. The gap between the shaft and the bearing bush and the center distance of the driving shaft and the driven shaft are the key points for overhaul. After years of practice, the universal use of the sample shaft has shortened the inspection time, improved the quality of maintenance and reduced maintenance costs. Certainly works. When measuring the clearance of the main shaft, use the short shaft and use the same method. If the clearance is not suitable, it can be solved by scraping the bearing bush and adjusting the gasket. Before use, when measuring the center distance between the main shaft and the rotor shaft, it is limited by the structure of the compressor and can only be measured at the journal, which affects the accuracy of the measurement. Use the sample axis to measure the center distance, put the spindle sample shaft and the rotor sample shaft into the respective bearing holes, and tighten the bearing cover, and then use the block gauge or caliper to measure the minimum between the two axes, which is convenient and quick. From the comparison of the above-mentioned maintenance methods and maintenance practice, the use of the sample shaft has received certain effects: (1) The sample shaft is much lighter than the rotor shaft weight, and the labor intensity of the maintenance personnel is alleviated during the maintenance. (2) Since the rotor shaft and the main shaft are not involved in maintenance, the damage rate of these parts is reduced. (3) Reduce the maintenance cost, scrape the spindle bush, no need to lift the spindle, and save 40% of the lifting time. (4) When measuring the bearing clearance, it can reduce the complicated procedure of the lead, saving the inspection time. (5) Improve the accuracy of the measurement data, thereby improving the quality of maintenance and prolonging the operation cycle of the equipment. 3-5 Ton Standing On Type Towing Tractor
