In this way, overhaul can improve the efficiency of air compressor equipment

What are the work contents of the overhaul of the main engine of the air compressor?

1. Disassemble, pull and press out the corresponding gears (or pulleys and other transmission devices) and bearings;

2. Clean the screw and shaft, adjust the gap, polish and repair the damaged surface of the shaft, screw and stator;

3. Press-fit the bearing, adjust the gap, and test each gap;

4. Trial run, run-in adjustment.

What problems should be paid attention to during overhaul?

1. Be careful during the disassembly process to avoid damage to the screw meshing surface and lock the thread;

2. Before installation, the unit should do a good job of cleaning all parts;

3. Replace the entire set of bearings with a special original brand.

What is the technical standard for air compressor overhaul?

1. Grinding the scratches on the rotor and the shell of the main engine head;

2. Calibrate the rotor, adjust the gap; overhaul the oil circuit of the main engine, the precision of the gear, and the concentricity of the bearing;

3. The exhaust pressure does not drop by 5% compared with the new machine;

4. The actual displacement under specified working conditions should not be less than 95% of the nominal displacement;

5. The rotor should be tested for dynamic balance, and its balance accuracy level should not be lower than G6.3;

6. The general vibration intensity should not be higher than 12mm/s (depending on the specific model and the degree of rotor loss), and there is no obvious abnormal sound.

Timely overhaul of the air compressor will help prolong its service life. At the same time, it also plays an important role in maintaining normal production and ensuring product quality, making it a strong backing for enterprises to win market competition.
