We all know that many users' air compressors will have high temperature during operation. This is also a common problem, especially for air compressors working outdoors. There are many reasons for the high temperature of air compressors in summer. Here are some common reasons for the high temperature failure of air compressors. When the high temperature alarm appears, you can do the following tests:
1. Check the cooler of the air compressor. If it is an air-cooled cooler, check whether there is too much dust. Too much dust can easily lead to poor ventilation, so that the air compressor equipment cannot achieve sufficient heat dissipation and is prone to high temperature. If it is a water-cooled model, check whether there is too much scale that causes blockage, which cannot take away the oil point temperature and achieve the heat dissipation effect.
2. Check whether the lubricating oil and oil level of the air compressor are lower than the minimum limit of the oil mirror. When there is too little lubricating oil, the air compressor cannot get enough cooling and lubrication during the entire operation.
3. Check the temperature control valve. The temperature control valve is like a four-way valve. When the temperature is low, the lubricating oil circulation is directly from the oil separator to the main engine head for lubrication and heat dissipation. When the temperature in the oil circulation generally reaches about 80-88℃, the temperature control valve will gradually open to allow the oil in the oil separator to cool through the cooler and then send it to the main engine to achieve the cooling cycle.
4. Check the oil cut-off valve and oil filter. The oil filter is blocked, which will cause the main engine head to enter too little oil. Generally, the oil filter has a service life and must be replaced after the expiration. If the oil cut-off valve is not fully opened, it will also cause too little oil to enter, causing the main engine head to gradually heat up until the alarm stops.
5. Check the temperature sensor. The temperature sensor is a thermal resistor that plays the role of a detection signal and transmits the signal to the computer main controller. If the temperature sensor fails, the detected temperature will be inaccurate, and the poor contact of the sensor line will cause the main control alarm to stop.
