Background technique
In the prior art, the starting drive of urban electric power big bus passenger vehicle is mainly joined piston type air compressor, and not only volume is big, safeguards also inconveniently, selects screw air compressor afterwards for use, but the noise of screw air compressor than higher, customer responsiveness is not ideal.No matter piston type air compressor or screw air compressor in the technique scheme, host shell and Oil-gas Separation tank shell are two independently parts, it not only causes the volume of air compressor bigger and impracticable, and it is many to connect the pipeline of each parts, and leakage of oil or pressurized air leak easily.
Summary of the invention
The host shell that the invention solves the prior art existence is that spiral case and Oil-gas Separation tank shell are two independently parts, it not only causes the volume of air compressor bigger and impracticable, and the pipeline that connects each parts is many, easy problems such as leakage of oil or pressurized air leakage provide a kind of compact structure, reliable performance, have been convenient to the single star wheel single screw air compressor of M R.
Above-mentioned technical purpose of the present invention solves by the following technical programs: it comprises the chassis, the chassis is provided with motor, main frame and oil gas crude separation device, main frame has suction port and relief opening, the suction port of main frame is connected with air filter, main frame adopts belt to be connected with motor, the Oil-gas Separation tank shell and the host shell of described oil gas crude separation device are cast as one up and down, the inner chamber of Oil-gas Separation tank shell directly is communicated with by through hole with the inner chamber of host shell, and cooler is fixed on below the motor base.The present invention is with host shell and the catch pot case design structure that is formed in one, can make the overall structure of worm compressor comparatively compact, directly be communicated with between host shell and the Oil-gas Separation tank shell by through hole, having saved host shell is connected with pipeline between the Oil-gas Separation tank shell, improved the reliability of performance of the present invention, thereby be convenient to M R, and reduce the possibility of leakage of oil or pressurized air leakage greatly.
As preferably, the lower end of described Oil-gas Separation tank shell is provided with base, is connected by screw or bolt between described base and the Oil-gas Separation tank shell.Wherein, the sealing that base can be convenient to the utility model Oil-gas Separation tank shell inner chamber is set in the lower end of catch pot.
As preferably, described catch pot lower part of frame is similar to rectangular structure, and the top of catch pot is similar to the segment structure.Wherein, the catch pot lower housing portion adopt the structure of approximate cuboid can be convenient to installation of the present utility model or with other parts between be connected.
As preferably, described host shell surface is respectively equipped with oil cut-off valve joint chair and the empty filter joint chair that is communicated with the host shell inner chamber.
As preferably, described catch pot surface of shell is provided with oil segmentation core joint chair, oil filler, oil filter joint chair, level meter joint chair and the relief valve connection that is communicated with Oil-gas Separation tank shell inner chamber.
Therefore, the present invention has compact structure, reliable performance, is convenient to M R, and can reduce the characteristics such as possibility of leakage of oil or pressurized air leakage greatly.
