In the daily use of air compressor, many faults are caused by improper electrical system configuration of air compressor faults, or even safety accidents.The following is a brief description of the following air-compressor electromechanical gas system configuration needs to pay attention to the safety related matters:
1, according to the power of the air compressor, the correct choice of the power line diameter, not too small wire diameter, otherwise the power line is easy to burn out due to high temperature and lead to danger.Grounding wires must be installed for the motor or system to prevent dangerous leakage of electricity.Note: the ground wire should not be directly connected to the air conveying pipe or cooling water pipe.
2, air compressor had better use a set of power system alone, especially to avoid parallel use with other different power consumption.Such as parallel use, may be due to excessive voltage drop or three-way current imbalance formation of air compressor overload, make the protection device skip, and affect other electrical equipment, high power air compressor especially pay attention to.According to the air compressor power selection and configuration of the appropriate air switch, to maintain the electrical switch in the system, and ensure safety.
3. The running current of the motor shall not exceed 15% of the rated current;If the three-phase current is unbalanced, the difference between the lowest phase current and the highest phase current of the air compressor shall not exceed 5%.If there is a voltage drop in the supply, it must not be less than 5% of the rated voltage.
4. Make sure that the power supply voltage is consistent with the rated voltage of the motor.
