The operators of Kaishan Air Compressor must have encountered the problem of the main engine or motor overload and shutdown. Don't worry, Anshan Xingsheng Air Compressor Co., Ltd. will share your worries and solve your difficulties.
First, the voltage is too low:
The additional working pressure of the general hill-opening air compressor is 380V, and the upper and lower promises to float at about 5%. The voltage mentioned here is the normal working voltage of the machine, because the transformer is relatively small on many construction sites (the factory voltage supply is relatively stable, generally does not have this situation) and the time voltage when the equipment is not open is 400 V, but when the equipment is open, the voltage drops to 350 V. The normal working voltage is only 360V. The short-term operation is not a big problem. Assuming long-term operation, it is bound to be applied to the electrical system. It constitutes great damage.
2. The pressure of the air compressor unit exceeds the additional pressure.
For example, when the practical pressure of a 0.7 MPa machine reaches 0.75 MPa, overload simply occurs. 7 kg air compressor should not be adjusted to 8 kg. No. 1, safety is not guaranteed. Secondly, the equipment can not withstand voltage and the life is shortened. So as much pressure as the demand is, choose the air compressor with the corresponding pressure.
3. Loose wiring:
To check whether the power supply line of the input screw air compressor has traces of heating and scorching, the first thing is to check the three-phase voltage line. If there is loosening or short circuit, then it is better to reconnect.
4. Contactor faults of mountain air compressor:
Contacts inside the contactor aging, poor suction, contact surface is small, the current is large, air compressor overload is a trivial matter, electrical system burning is the work we do not want to see.
5. Blockage of oil and gas separated from core in mountain air compressor:
The oil core is blocked, the internal pressure is high, the load is large, the current is high, so it will overload. Misconception: Do not think that new things will not be blocked soon, the site environment is dirty, and many impurities in the oil and gas barrel simply make the oil core separation blocked. The new oil core separation, the environment is also possible, but the work of 200 hours and blocked, which is related to the quality of oil core separation.
