Hanzhong screw compressor motor maintenance aspects of mature, unique technical support. For the mastery of refrigeration compressor stator rewinding technology, the imported fluorine-resistant wire and vacuum dipping technology are adopted to ensure the uniformity and permeability of the insulating paint; the special fluorine-resistant and high-temperature resistant insulating materials can achieve the H grade. Powerful guarantee of the service life and performance of the compressor motor. In terms of test and test, the newly developed star-delta start test bench is specially prepared for the motor test and inspection of large-scale refrigeration compressors. This test can achieve the most realistic compressor operation data and ensure that the operation after installation can meet the requirements.
Hanzhong screw compressor repair:
1. Lack of oil: The oil film in the compressor is thin or has no oil film, the lubrication disappears, dry friction occurs between the mechanical parts, the wear is serious, and the grinding debris becomes abrasive sand, causing more serious wear, so the vicious cycle leads to the final Holding the shaft.
2, the refrigeration system is dirty: the dirt itself causes wear between the compressor components, a particle is equivalent to a sharp knife, so that more and more particles are drawn, resulting in the axle.
3, oil filter blockage: causing oil return problems, resulting in poor lubrication, accelerated wear, resulting in the axle
4, bearing wear: bearing wear, the support of the screw deviates from the original center, the axis is skewed, so that the gap between the screw and the bearing seat becomes smaller on one side, destroying the lubrication effect of the oil film; The axial and radial positioning effects are worse, the screw is turbulent, causing wear on the compression chamber and high pressure end face of the compressor, and also causing the axle or sweeping
5, oil aging: the oil does not play the role of lubrication and take away heat, and the effect of temperature on the performance of the oil is very large, which degrades the performance of the oil, resulting in increased friction, eventually leading to the axle
6. The system lacks fluorine: after the lack of fluorine, the heat is stored in the compressor, the temperature rises, the viscosity of the oil is lowered, and the lubrication is not well, resulting in wear.
7. The condensing temperature is too high: it affects the viscosity of the lubricating oil and causes wear. Hanzhong screw compressor repair - screw compressor repair
8. Excessive heat load: affects the viscosity of the lubricating oil and causes wear.
