The application discloses a screw compressor with a leakage-proof detection function, and relates to the technical field of compressors.The screw compressor comprises a compression mechanism, a leakage-proof detection mechanism, a driving mechanism, a storage mechanism and a temperature control mechanism.The compression mechanism and the storage mechanism are fixedly connected, the leakage-proof detection mechanism and the compression mechanism are fixedly connected, the driving mechanism and the compression mechanism are in transmission connection, and the compression mechanism and the storage mechanism are both in communication with the temperature control mechanism.The compression mechanism prevents oil and gas from leaking during the compression process, thereby ensuring the compression efficiency.The leakage-proof detection mechanism is used for monitoring the sealing state and pressure change in a compression chamber.The driving mechanism provides stable power output, and the gas compression process continuously proceeds.The temperature control mechanism reduces the overheating problem of the machine body and lubricating oil caused by continuous compression, thereby maintaining the stability of the compressed medium, preventing the oil film from being broken, the sealing from being invalid or the lubricating oil from being deteriorated, and improving the operation safety and service life of the whole machine.
