The reason why the Jufeng air compressor leakage switch tripped when the star connection was changed to delta: The star connection method means that the coil voltage of each phase of the motor will be of 220V (phase voltage), but after switching to delta connection, each phase of the motor The coil voltage becomes 380V (line voltage). So the leak switch tripped.
Leakage switch, a type of switch, is mainly used to prevent leakage accidents. The working principle of the switch is as follows: there are two windings on an iron core, a main winding and a secondary winding. The main winding also has two windings: the input current winding and the output current winding. When there is no leakage, the input current and output current are equal, and the vector sum of the two flows mamagnetic on the iron core is zero, and no potential will be induced on the secondary winding. Otherwise, voltage will be induced. on the secondary winding, and the actuator will be driven by the amplifier, causing the switch to trip.

Generally, air compressors have two passwords: one is the user password and the other is the manufacturer's password. The password for each air compressor manufacturer. are all different.
For the safety of customers, the password of the air compressor is usually kept by the manufacturer and will not be easily disclosed to third parties to prevent customers from changing settings randomly and cause malfunctions. For specific information you can. consult the manufacturer or the place where the product was purchased.
Very weak.
EtaSince the screw air compressor has the characteristics of high stability, low vibration and low noise, the cooperation between the yin and yang rotors and the rotor and the housing is adjusted, so there is less backflow gas leakage, and at the same time, there is no remaining space volume, so the failure rate of Jufeng screw air compressor is very low.
The screw air compressor adopts a pre-packaged configuration. The screw air compressor only needs one electrical connection and one compressed air connection, and has a built-in cooling system, which greatly simplifies the installation work.
