The air compressor rotor rotates at high speed, while the end face is stationary. There is a certain gap between them, and the clearance adjusted by the higher the compressor power is, the larger the clearance will be. When the compressor rotor is assembled, it is very important to adjust its clearance. If it is increased, it will affect the compressor exhaust volume. If it is small, it will easily cause high temperature friction. The end clearance of screw compressor is determined by the designer at the time of design. General clearance is determined by the size of the machine, operating conditions, materials of the rotor and its cylinder. As long as the clearance is within a certain range, it will not affect the normal operation of the machine.

If the air compressor head needs to be overhauled after many years of use, it is better to know the clearance range of the head from the manufacturer when repairing, and it is better to measure the accurate clearance value of the machine when disassembling the machine, and try to ensure the clearance value when installing. Of course, the structure of each manufacturer is different, gap adjustment is also different, specific issues need to be analyzed. If the said nose failure is caused by working conditions, the operating environment can be improved by using air filters under bad working conditions, and the main engine can be cared for from the source to reduce operating costs.

The inlet and exhaust end clearance of the main engine of screw air compressor is mainly caused by the thermal expansion in the sealing chamber, so there are different clearances. In addition, the thrust bearing is used at the exhaust end because the force at the exhaust end is greater than that at the intake end. Excessive clearance at the exhaust end affects the compression efficiency; too small, the thermal expansion clearance must also be guaranteed. At this time, bearing clearance should also be taken into account. In the maintenance of the main engine, we can relax a little, mainly to ensure normal operation. The clearance between the rotor and the casing is roughly the same. The main screw machine is a precise part. Only by fully mastering the relevant maintenance technology, can it be well maintained. Finally, the repaired main engine is inspected and put into operation after commissioning.
