Screw Air Compressor maintenance can be divided into minor repairs to repair and overhaul, only about distinguish between them, there is no absolute boundaries, and the specific condition of each unit is different, so different division.
The general minor repairs are to eliminate individual defects of the compressor and to replace the individual parts, including: inspection of the carbon footprint of the rotor at the inlet;Check the inlet valve cylinder diaphragm;Check and tighten the screws in each part;To clean air filters;Eliminate air compressor and pipe leakage and oil seepage;To clean the cooler and replace the failure valve;Inspect the safety valve and pressure gauge.
The medium repair generally runs 3000 ~ 6000h for once.In addition to the whole work of minor repair, the repair and replacement parts should be removed, such as removing oil and gas drums, replacing oil filter and oil separator, and inspecting the wear condition of the rotor.Disassemble and adjust the heat control valve and pressure maintenance valve to restore the machine to normal operation.
Air compressor host is the core part of the air compressor, in a state of high speed for a long time, because the service life of components and bearing has its corresponding to its operation to a certain time or after a fixed number of year must be preventive overhaul, overhaul of the main content includes: (1) overhaul host and gear box;(2) motor bearing and butter;(3) check or replace the coupling;(4) cleaning and maintenance of air cooler;(5) clean maintenance oil cooler;(6) check or replace the check valve;(7) check or replace the relief valve;(8) clean water vapour separator;(9) replace lubricating oil;(10) the heat dissipation surface of the cleaning unit;(11) check the working conditions of electrical components;(12) check the protection function and its setting value;(13) check or replace the pipes;(14) check the contact information of electrical components.
