The normal working temperature of screw air compressor accessories is between 75 and 95 C. When the temperature exceeds the limit, it belongs to high temperature. There are many reasons for the high temperature. Analyzing and judging the cause of high temperature of air compressor is the premise and foundation to solve the problem of high temperature of air compressor. Equipment operating at high temperature in summer may encounter the following problems in summer:
1. Insufficient lubricating oil
Not only the lubricating oil of screw air compressor is lubricated and sealed, it is also the main cooling device, so it is also known as "coolant". When the machine lacks coolant, the heat generated by the compressor can not be cooled, and the temperature will rise higher, which is also a major factor causing high temperature screw air compressor.
Solution: add air compressor oil, if high temperature causes lubricant deterioration, then replace.
2. Failure of temperature control valve
The function of the temperature control valve is to control the injection temperature of the main engine of the oil injection screw air compressor. It uses temperature control elements to control the opening of the valve core according to the oil temperature, so as to control the amount of oil through the oil cooler, so that the cold and hot oil can be mixed into the main engine, thus controlling the temperature of injection and exhaust.
Solution: Replace the temperature control valve core.
The cooler is blocked.
Cooler is also commonly known as "radiator fin". The lubricant circulated in screw air compressor is cooled by the cooler and then returned to the compressor main engine. When the cooler is too dirty and blocked, the lubricant of air compressor can not be cooled, so the recovery will lead to high temperature.
Solution: Clean the cooler with dry compressed air. If the cooler cannot be cleaned, remove it and clean it.
4. Blockage of oil filter
The function of oil filter is to filter impurities in lubricating oil and protect the main engine of screw air compressor. If it is not replaced for a long time, or the working environment is not good, the oil filter will be blocked, the oil flow in the compressor is small, and the main engine can not get enough lubricating oil to cool in time, and high temperature will occur.
Solution: Change the oil filter, or do a comprehensive oil maintenance.
5. Failure of Main Controller of Screw Air Compressor
There is a random alarm. If this is the reason why the air compressor panel shows high temperature.
Solution: Replace the main controller.
Temperature sensor failure
Air compressor panel shows unstable temperature change, or rising speed increases by several degrees Celsius or more, indicating temperature sensor failure.
Solution: Replace the temperature sensor.
