In the course of use, there will always be some faults, which will cause the air compressor to suddenly trip during the operation of the air compressor, which will affect the use of the site. The following common faults of the air compressor are listed:
1) The air compressor is stopped at high temperature.
2) The air compressor mainframe is overloaded and the main engine is unbalanced.
3) The air compressor main engine is abnormal.
Most of the problems we encounter in use are these three aspects. For these problems, we can detect the troubleshooting according to the following operations:
1) For the high temperature of the air compressor,
1. First of all, to ensure that the rotor coolant of the air compressor is within the specified range, the quality of the air compressor rotor coolant directly affects the heat dissipation effect of the air-cooled screw air compressor, and check the air compressor in the oil and gas barrel during operation. The position of the coolant is added as required by the coolant.
2. Check the ventilation of the air compressor room to ensure that the surrounding environment of the air compressor is within the normal range. If the conditions are not allowed, the air duct can be added at the radiator position.
3. In order to ensure the above conditions are normal, check the ventilation of the air compressor radiator, the radiator is generally aluminum products, under normal circumstances, we check the ventilation of the radiator can directly check the transmittance with the object with the light source, if If the light transmission is not good, clean it in time. Clean it is not to use the hard object directly on the radiator. When the radiator is damaged, it should be dredged with dry gas. For the water-cooled air compressor, clean the inside of the cooling water. Scale to avoid blockage of the pipeline.
2) For host overload, first measure whether the three-phase power of the air compressor is balanced, and whether the air pressure power cable connector is loose or falling off. If the three-phase voltage of the air compressor is not balanced, adjust the external voltage. Or install a voltage regulator next to the air compressor. If all the above test items are normal, the air compressor current transformer will be faulty and replaced directly. For the overload of the air compressor main engine, the imbalance is caused by the unstable voltage of the air compressor, which causes the grid to fluctuate greatly, which causes the internal self-protection function of the air compressor.
3) The abnormal noise of the host is generally caused by two reasons.
1. The main bearing of the air compressor is worn, which causes the yin and yang rotor of the air compressor to shift, resulting in abnormal noise caused by the collision of the two rotors. In this case, the air compressor bearing is directly replaced.
2. The amount of impurities in the sludge contained in the air compressor coolant causes the friction of the air compressor rotor to mesh. The solution is to replace the air compressor rotor coolant and cool the internal rotor. Liquid cleaning.
