Quality standard for major overhaul of screw air compressor host
Release time:
2026-01-15
The quality standards for the major overhaul of screw air compressors include four aspects. It is achieved through a series of measurement methods after the entire repair process of the equipment is completed. The specific contents are as follows:
1. Gap measurement
The first thing to consider in the overhaul of the air compressor host is definitely the clearance between the rotor and various components, which can be calculated using a feeler gauge. At this time, the quality standard is to check whether the data matches the calculated value. Only when the tooth clearance is the most appropriate can the standard be achieved. Excessive friction or air leakage are the most likely to cause malfunctions.
2. Due to prolonged use, rotors and other components often experience significant surface wear. Failure to replace them in a timely manner can result in axial misalignment. In such cases, they can be replaced or certain control nuts can be adjusted.
3. Trial operation
Check whether the voltage, circuit and other values are within the allowable fluctuation range; Are there any abnormal vibrations; Seal integrity to avoid oil leakage.
4. Temperature is the key to major maintenance of the host, and the lubrication level of each component must be in good condition.
Regardless of the external conditions, the overall quality standards for the overhaul of screw air compressor heads are consistent. Therefore, users can refer to these values to inspect their machines and avoid any abnormal problems.
