Thread Content

York screw RXF-XJF compressors, industrial refrigeration unit maintenance and repair projects. Maintenance projects: 1. Include the repair projects. 2. Dismantling and overhauling of the compressor unit: 3. Measuring the radial runout of the shaft journals of the male and female rotors, and performing rotor dynamic balancing correction if necessary ； 4. Measure the radial clearance between the male and female rotors and the housing, as well as the radial clearance between the spool valve and the frame ； 5. Measure the gap at the meshing line of the male and female rotors ； 6. Measure the meshing clearance and side clearance of the synchronous gears ； 7. Measure the gaps between the rotor’s exhaust end face and the exhaust end seat, as well as between the suction end face and the suction end seat ； 8. Measure the gaps between the balance piston and the balance piston sleeve, as well as between the oil piston and the oil cylinder ； 9. Measure the clearance between the bearing retainer and the outer end face of the thrust bearing ； 10. Measure the clearance of the sliding bearing ； 11. Measure the axial movement of the screw and the clearance between the outer surface of the rotor and the cylinder block (LPG screw compressors). 12. Check the wear condition of the inner surface of the machine body, the surface of the spool valve, the surface of the rotor, as well as the ends and the suction and exhaust end seats. 13. Measure the dimensions of various parts such as the inner diameter of the machine body, the outer diameter of the spool valve, the outer circumference of the rotor, and the balance piston. 14. Inspect and replace rolling and sliding bearings. York screw RXF-XJF compressors, major and minor repair projects for industrial refrigeration units
