Reuse process is always over temperature, I do not know what the problem is.
Air suction, scheduling, and control of components such as the pipeline will cause compressor malfunction and overheating faults.(1) check that the air filter is blocked. Can be checked or replaced according to the alarm signal of the pressure differential switch.(2) check whether the pressure is too high. The system pressure is usually adjusted at the factory. If it is necessary to adjust, the rated gas production pressure shall be subject to the nameplate calibration. If the adjustment is too high, as the machine load increases, will lead to overheating phenomenon.
There are many reasons for overheating fault of air compressor. The main reasons are as follows:1, insufficient oil or oil tank components will cause abnormal oil temperature rise, thus causing overheating faults. Such as:(1) insufficient oil supply: first, check the oil filter and the oil separator is blocked. Second, check whether the oil regulator is normal and increase fuel injection when necessary.(2) the oil stop valve does not work properly: the oil stop valve is generally two to two normally closed solenoid valve, start stop open, closed, to avoid downtime when oil and gas in the barrel of oil to spray into the nose, and ejected from the air inlet.(3) the work of the thermal control valve is out of order: the heat control valve is installed in front of the oil cooler, and its function is to maintain the exhaust temperature above the pressure dew point. The main reason of failure, one is to change the elastic coefficient on the spool size two thermal spring fatigue, can not change with temperature is normal operation; two body wear, the valve stuck or action is not in place and can not normally closed. Can be repaired or replaced according to the situation.
The cooling of the air compressor itself is to spray the compressed oil from the lower end of the body and the left and right sides into the compression chamber, and join with the inhaled air to compress the oil tank from the bottom of the mainframe to the oil and gas tank. In addition to the screw and gear and other components of harmony, but also a large number of tropical out. But the heat has not been transferred, before the next fuel injection action, but also through the oil cooler before cooling to completely cool down. Therefore, the occurrence of overtemperature faults is mostly related to the harmony and abnormal cooling system.
