Factor one, the exhaust temperature is too high
High exhaust temperature is a relatively common fault of air compressors, this hazard is also very large, usually the working temperature of the air compressor is between 65 ° C - 85 ° C, and the normal exhaust temperature is set at 100 ° C. When this temperature is exceeded, the compressor will automatically stop working and issue an alarm. If the compressor equipment is operated under high exhaust temperature conditions for a long time, excessively high temperatures will cause changes in the physical coefficient values of the rotor and bearing material, resulting in abnormal friction losses in the bearing and even bearing loosening.
Too high an oil temperature will also reduce the gas transfer coefficient and increase power consumption, and the viscosity of the air compressor lubricating oil will also be reduced. Too high a temperature can also cause the air compressor lubricating oil to thermally decompose under the catalysis of the metal, forming free carbon and acids that are harmful to the work.
In severe cases, material and moisture (carbon build-up) can get stuck in the screws of the entire air compressor host, or the compressor machine will stop and run. Although the air compressor is equipped with a protective device to prevent high temperatures, the presence of failure will still make the device run frequently, affecting the normal operation of the enterprise.
Factor two, the actual exhaust temperature is not high
The thermometer display of the air compressor is inaccurate; Air compressor temperature sensor failure; Air compressor controller failure; The temperature switch of the air compressor is faulty.
Factor three, the actual exhaust temperature is too high
The lubricating oil is used for too long, the oil filter element is blocked, the oil distribution element is blocked, the temperature control valve fails, the lubricating oil level is too low, the ambient temperature is too high, the fan motor is reversed, the fan motor does not rotate, the outside of the air cooler is always too dirty, the oil circuit of the air cooler is seriously scaled, the exhaust channel of the cooler is not smooth, the cooling water pressure is too low, the cooling water temperature is too high, and the cooling water outlet pipe is blocked.
