High-speed centrifugal turbine compressor for chloromethane and chloroethylene

The utility model relates to a chloromethane and chloroethylene high-speed centrifugal turbine compressor. A first-stage compression main engine, a second-stage compression main engine, a motor and a speed increasing box are all arranged at the top of a base oil tank; a large gear and a small gear are assembled in the speed increasing box, the large gear is assembled on the low-speed shaft, and the small gear is assembled on the high-speed shaft; and the other end of the high-speed shaft is provided with a secondary compression main engine. No friction exists between the working wheel and the machine shell, and lubrication is not needed. The compression process is absolutely oil-free, and the product quality is improved; the centrifugal compressor is large in gas transmission amount, simple and compact in structure, light in weight, small in unit size and small in occupied area; friction pieces and spare parts are few, and the maintenance cost and the labor cost are low; the service cycle is long, the service
