1. Temperature sensor failure. The air compressor panel shows unstable temperature change, or an increase of several degrees Celsius or ten degrees Celsius in the rising speed, indicating that the temperature sensor is faulty.
Solution: Replace with a new temperature sensor.
2. The temperature control valve is faulty. The function of the temperature control valve is to control the oil injection temperature of the screw air compressor main engine; the temperature control element is used to control the amount of oil passing through the oil cooler according to the opening degree of the valve core of the oil temperature control element, and the hot and cold oil is mixed into the main engine. , control the fuel injection and exhaust temperature!
Solution: Replace the temperature control spool.
3. The oil filter is clogged. The function of the oil filter is to filter the impurities in the lubricating oil to protect the main engine of the screw air compressor. If it is not replaced for a long time, or the use environment is bad, the oil filter will be blocked, the oil flow in the compressor will be small, and the main engine cannot get enough lubricating oil cooling in time, and high temperature will occur.
Solution: Replace the oil filter, or do a full oil circuit maintenance.
4. The cooler is clogged. Coolers are also commonly referred to as radiators. The lubricating oil circulating inside the screw air compressor should flow back to the compressor host after cooling in the cooler. When the cooler is too dirty and clogged, the lubricating oil of the air compressor cannot be cooled, so the circulation will cause high temperature.
Solution: Clean the cooler with dry compressed air, if it cannot be cleaned, disassemble and clean it.
5. The main control of the screw air compressor is faulty. Random alarm. If the air compressor panel therefore shows high temperature.
Solution: Replace with a new master controller.
6. Lack of lubricating oil. The lubricating oil of the screw air compressor not only has the functions of lubrication and sealing, but also can cool the unit, so it is also called coolant. When the machine lacks coolant, if the heat generated by the air compressor cannot be cooled, the temperature will rise, which is also one of the main factors for the high temperature of the screw air compressor.
Solution: Add air compressor oil. Replace if lubricant quality deteriorates resulting in high temperature.
The wear and replacement of parts and regular maintenance are also one of the prerequisites for the smooth operation of the air compressor. Therefore, the operation of the air compressor should not be damaged due to the failure of the parts in the daily work.
