1, voltage instability
The voltage of variable frequency air compressor is often unstable in use. Once the voltage is unstable, there will be a load phenomenon, and even the variable frequency air compressor can not be started normally, resulting in changes in cylinder pressure. It can be solved by adjusting the voltage regulator in time.
2. The motherboard is damaged
Frequency conversion air compressor is easy to be damaged in the process of long-term continuous use. After the motherboard is damaged, the internal components of the equipment can't work normally to release air pressure. Users need to check the motherboard in time and replace the electronic components or motherboard to solve the problem.
3. The cooling fan is damaged
In the process of using variable frequency air compressor, there will also be inverter failures caused by excessive temperature. At this time, it is necessary to check whether the cooling channel of the inverter is blocked, and pay attention to whether the cooling fan is damaged, and solve it through replacement or maintenance in time.
4. Insufficient exhaust capacity
Sometimes when the equipment is working, the exhaust capacity is suddenly insufficient. At this time, you can check the intake filter of the variable frequency air compressor to see if there is any blockage caused by dirt deposition, or if the intake pipe is too long and the cross section of the pipeline is too small, which will lead to the failure of air reduction. It can be solved by cleaning or replacing the equipment frequently.
5. External input failure
During the operation of variable frequency air compressor, there will be external input failure, and external failure will also lead to abnormal operation of the whole variable frequency air compressor.
External faults can usually detect whether the voltage value of the port is normal or not, and check whether the short-circuit cap connected between the control panel and the equipment falls off. You can also short-circuit the emergency stop switch with wires to see if it is damaged. The fault of external input can be solved by replacement or installation.
