In this paper, the work of screw compressor air flow principles and the work of a more comprehensive analysis of the fuel injection compressor fault common causes. Screw air compressor on the course in the use of the mouth of the problem, screw air compressors from the working principle of analysis, such as the nose temperature is too high. Often run when the process of cooling the oil problems such as oil filters filter, broken Oil valve plug so that the oil was to reduce the impurities; material aging or temperature control valve plug so that higher oil temperature, oil cooler of the scale thickness to a certain extent affect the cooling effect and so on. Should be taken to regularly clean filters, the valves 80 ℃ Add the water to determine whether or not the aging, the use of acid descaling cycle, the observation of the pressure oil filter parameters, a higher than standard, the timely replacement of oil filter to ensure that the air compressor head does not appear in the condensation temperature of water running and so on.
