Many people use screw air compressors to find that screw air compressor is temperature, which is normal. However, if the temperature of the screw air compressor is too high, we should pay attention to it, because in this case, it often means that your screw air compressor has failed, so we have to stop the inspection immediately. As for the places to check, Xiaobian is here for everyone to introduce.

Screw air compressor Overhaul of high temperature: The premise is that the temperature of the engine room is within the permissible range, and the oil level is in a normal state.

First confirm whether the screw air compressor is faulty in the machine temperature measuring component, and it can be proofed by another temperature measuring instrument. If it is confirmed that there is no problem with the temperature measuring component, then check the temperature difference between the oil cooler inlet and outlet. Normal between 5 and 8 degrees. 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. If the oil filter is used, consider whether the flow is insufficient. Check the front filter. For some models, adjust the oil flow rate to the maximum. Check whether the 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. If the above method is not solved, it is necessary. Consider whether the oil path is blocked by foreign matter. If the temperature difference is less than the normal range, it proves to be poor heat dissipation. Please check if the water intake is insufficient, whether the inlet water temperature is too high, whether the cooler is scaled, whether there is grease in the cooling, and if the air is cold, check if the radiator is too dirty. The cooling fan is abnormal, the air volume is insufficient, whether the air duct is blocked, whether the air duct is too long, the relay fan is not added, the relay fan is not turned on, or the relay fan is faulty. Is there 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 it is a bearing problem or even an end face friction. In addition, if there is a fuel cut-off valve, it is necessary to check whether the screw air compressor is faulty. The oil shut-off valve fault will normally jump when the power is turned on, and the temperature will rise linearly.
