The invention discloses a screw rod type air compressor. The screw rod type air compressor comprises a machine shell, a drive shaft, a male screw and a female screw. A water cavity is formed in the side in the machine shell, a compression bin is arranged in the machine shell, an air inlet and an air outlet are formed in the two ends of the top of the compression bin, four screw bearings are symmetrically mounted at the two ends of the compression bin, the male screw and the female screw are sleeved with the compression bin and are in engaged connection, the two ends of the male screw and the two ends of the female screw are rotationally connected with the four screw bearings in a one-to-one-correspondence manner, one end of the drive shaft penetrates through the inner wall of the machine shell, the other end of the drive shaft is fixedly connected with the middle of a drive gear, and the drive gear is in engaged connection with a transmission gear. As the water cavity is formed in theside in the machine shell, when the air compressor works, a machine body can be cooled; and as an air pressure valve is arranged at the bottom of the compression bin, the air compressor valve can be manually switched on every time before the air compressor is started, high-pressure gas left in the compression bin is removed, and overloading is avoided.
Description
technical field [0001] The invention relates to the technical field of air compressors, in particular to a screw-type air compressor. Background technique [0002] Air compressors are essential equipment for various factories, road construction, mines and construction industries. They are mainly used to provide a steady stream of compressed air with a certain pressure. There are many types of air compressors, among which screw compressors are a relatively The novel compressor is widely used in mining, construction, chemical industry, metallurgy, power, machinery, refrigeration and other industrial sectors because of its high reliability, convenient operation and maintenance, good power balance, and strong adaptability. [0003] However, the screw air compressor will generate heat during the process, which will affect the normal work. Moreover, there is still some residual pressure inside the machine that cannot be released after the machine is stopped. When it is started aga...
