Screw air compressor unit with energy storage

A screw air compressor unit with energy storage, comprising a power battery module, a frequency converter, a permanent magnet synchronous motor and a screw air compressor respectively provided thereon, wherein the screw air compressor comprises a pair of mutually meshing spiral rotors consisting of a male rotor and a female rotor arranged in a casing,

• the power battery module is composed of one or more battery cells or battery packs, mainly responsible for storing and releasing electrical energy, wherein the power battery module is correspondingly connected with the screw air compressor, and provides a power source therefor,
• wherein one end of the frequency converter is connected with the power battery module, and the other end is connected with the permanent magnet synchronous motor, wherein the frequency converter converts the electrical energy output by the power battery module into the voltage and frequency required by the permanent magnet synchronous motor, so as to start the permanent magnet synchronous motor to connect and drive the screw air compressor to carry out the repeated movement of air intake, compression and exhaust to achieve an inflation action.
