In the summer of Shandong, the air compressor should be shut down in order to solve the problem of high temperature.
1、 Check the cooler of the air compressor. If the cooler is air-cooled, check whether there is too much dust. If too much dust is easy to lead to poor ventilation, the air compressor equipment can not achieve enough heat dissipation, and high temperature is easy to occur; the water-cooled cooler will check whether there is too much scale blocking, and the oil point temperature can not be carried away, which can not achieve the cooling effect.
2、 Check whether the oil and oil level of air compressor is less than the minimum limit of oil sight glass. Under the condition of too little oil, the air compressor can not get enough cooling and lubrication in the whole operation process.
3、 To check the temperature control valve, the temperature control valve is like a four-way valve. When the temperature is low, the oil circulation is directly from the oil separator to the main engine head for lubrication and heat dissipation. When the oil circulation temperature generally reaches about 80-88 degrees, the temperature control valve will gradually open to let the oil from the oil separator be cooled by the cooler and then sent to the main engine to achieve cooling cycle.
4、 To check the oil cut-off valve and oil filtration, the blockage of the oil filter will lead to too little oil into the main engine head. Generally, the oil filtration is periodic and must be replaced. If the oil cut-off valve is not fully opened, it will cause too little oil into the engine head, which will make the engine head gradually warm up until the alarm stops.
5、 To check the temperature sensor and temperature switch, this is a very important check. The temperature sensor, which is a thermal resistance, plays a role in detecting the signal and transmits the signal to the main controller of the computer. If the sensor fails, the temperature detected will not be accurate, and the sensor line contact is not good, which will cause the master control alarm and shutdown.
Of course, these five inspections are relatively easy to occur when the air compressor is in high temperature, and other possibilities are not ruled out, such as whether the abnormal noise of the machine head, the damage of a certain part, the air compressor plays its own protective role, and the early warning is generated, so it is shut down.
