How to check if the temperature of screw air compressor is normal? Take advantage of this opportunity to share some dry goods in China DSNEAIR:
I: Confirm whether the air compressor is faulty in the machine temperature measuring device?

Can be proofread with another temperature measuring instrument If it is confirmed that there is no problem with the temperature measuring element, then check the temperature difference between the inlet and outlet of the oil cooler, which is normally between 5 and 8 degrees.
2: If the temperature is greater than this range, the oil flow is insufficient, the oil circuit is blocked, or the temperature control valve is not fully opened. Please check the oil filter. Please check the front filter. Some models have Please adjust the oil flow adjustment to the maximum; check whether the air compressor temperature control valve is normal, you can remove the valve core, close one end of the temperature control valve, and force the oil to pass through the cooler.

China Air Compressor Xiaobian reminds you that if the above methods are not resolved, it is necessary to consider whether there is any foreign body blockage in the oil circuit. If the temperature difference is less than the normal range, it means that the heat is not good. The water cooler should check if the water intake is insufficient; if the inlet water temperature is too high; if the cooler is scaled; if there is grease inside (the oil circuit part). Air-cooled machine, please check if the radiator is too dirty; if the cooling fan is abnormal, the air volume is insufficient; if the air duct is blocked; if the air duct is too long; the relay fan is not added; the relay fan is not open or the relay fan is faulty; There is grease in the radiator. If the temperature difference is within the normal range, the machine is still hot, indicating that the heat generated by the machine head is out of the normal range. It should be checked whether it is overpressured, whether the oil is wrong, whether the oil is aging, whether the machine is not bearing problems or even the end face friction.
