Compact oil-gas secondary separated air compressor

Abstract

The invention relates to a compact oil-gas secondary separated air compressor. The compact oil-gas secondary separated air compressor comprises a machine frame, wherein a gas storage tank and an oil-gas separation barrel are arranged on the bottom end surface of the machine frame, a gas return pipe is arranged at the front end of the gas storage tank, two supporting plates are arranged on the upper surface of the gas storage tank and the oil-gas separation barrel, a permanent magnet motor and a cold dryer are arranged on the upper surfaces of the two supporting plates respectively, a bearing plate is arranged on the upper surface of the gas storage tank, a double-screw main machine is arranged on the upper surface of the bearing plate, an oil return pipe is arranged on the left side of thedouble-screw main machine, the output end of the permanent magnet motor is connected with the double-screw main machine, an electric control box is arranged above the oil-gas separation barrel, the upper surface of the oil-gas separation barrel is provided with an air outlet pipe and an oil outlet pipe, the upper surface of the oil-gas separation barrel is also provided with a cooling device, andthe right side wall of the cooling device is sequentially provided with an oil return pipe opening, an air inlet pipe opening and an oil inlet pipe opening from left to right. The structure is smallin occupied area, space resources are saved, and movement can be realized; and heat can be dissipated through heat dissipation holes, and the gas storage tank is combined with the oil-gas separation barrel, so that secondary separation is realized, and the air compression efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of air compressors, in particular to a compact oil-gas secondary separation air compressor. Background technique: [0002] The air compressor is a kind of equipment used to compress the gas. It is mainly driven by the permanent magnet motor to make the twin-screw main engine rotate, which in turn causes the volume of the cylinder to change. Due to the change of the pressure in the cylinder, the air passes through the oil and gas through the intake valve. The separation barrel enters the gas storage tank; [0003] However, the existing air compressors mainly adopt stand-alone design, and the air storage tank and the oil-gas separation barrel are installed separately. Not only the installation steps are complicated, but also the floor area is too large, which wastes space resources and is not convenient for the staff to work. Because there is no rack setting, the noise is too loud during work, which affects ...

[0003] However, the existing air compressors mainly adopt a stand-alone design, and the air storage tank and the oil-gas separation barrel are installed separately. Not only the installation steps are complicated, but also the floor area is too large, which wastes space resources and is not convenient for the staff to work. Because there is no rack setting, the noise is too loud during work, which affects the health of the staff
