Screw air compressor maintenance manufacturers introduced the summer weather is very hot, the machine is easy to show high temperature, affect customer consumption. After the machine is in high temperature, the customer need not be too nervous, can according to the following way to stop the inspection disposal or contact air compressor customer service.
First confirm the screw air compressor machine temperature measuring elements can exist fault, can use another temperature measuring instrument to stop correction, if confirm the temperature measuring elements no problem, then check the temperature difference between the inlet and outlet of the oil cooler, normal between 5~8 degrees.
If the temperature is greater than this range, clarify that the oil flow is insufficient, the oil line is blocked, or the temperature control valve is not fully open, please check the oil filter, please check the first filter. Some models have oil flow conditioning please first conditioning to large, check whether the temperature control valve is normal, can take off the valve core, seal one end of the temperature control valve, force the oil all through the cooler, if the above way failed to deal with, it is necessary to think about whether the oil can have foreign body infarction.
If the temperature difference is less than the normal range, proved to be a bad heat dissipation, please check whether in the lack of water, water cooling machine can feed water temperature is too high, can cooler furring, whether inside cooling oil dirties, air-cooled please check whether the radiator is too dirty, whether a cooling fan is unusual, the lack of air volume, can have a duct duct infarction, whether duct is too long, without relay fan, relay fan has not opened or relay fan fault. Whether there is grease in the radiator.
If the screw air compressor temperature difference in the normal range, the machine is still high temperature, clarify the heat of the head beyond the normal range, should check whether the overpressure operation, whether the oil is not right, whether the oil aging, whether the head bearing problems and end friction.
In addition, there is a shutoff valve (also known as oil supply valve, stop the oil valve), to check whether there is a fault, shutoff valve fault will boot on the jump, the temperature straight line rise.
