Problems solved by technology
[0007] However, the existing two-stage air compressors still have the following problems: oil cooling structure is mostly used, the oil circuit structure is complex, high precision parts are required, the production cost is high, and maintenance is inconvenient; while the cooling effect of the air-cooled structure is poor, Most of the inter-stage compressed gas does not have a reasonable cooling structure, resulting in the problem of poor inter-stage cooling effect

The invention discloses a two-stage compression oilless piston compressor. The two-stage compression oilless piston compressor comprises a mounting base, a crankshaft box body fixed on the mounting base, a motor fixed on the mounting base and positioned on one side of the crankshaft box body, a crankshaft fixedly connected to a motor power shaft and positioned in the crank shaft box body, a first-stage cylinder barrel and a second-stage cylinder barrel respectively fixed on the crankshaft box body, a first-stage piston and a second-stage piston rotatably connected to the crankshaft through a connecting rod, a first-stage cylinder cover and a second-stage cylinder cover which respectively cover the upper ends of the first-stage cylinder barrel and the second-stage cylinder barrel in a sealing mode, and a gas pipeline arranged on the mounting base. The gas pipeline is reasonable in design and good in interstage cooling effect; the stress of structural parts of an air compressor is reduced and the service life of the air compressor is prolonged by adopting two-stage compression; single-stage compression power is reduced by adopting the two-stage progressive compression; and heat generated by compressed air of the air compressor is reduced by adopting an interstage cooling structure for cooling.
Description
technical field [0001] The invention relates to a two-stage compression oil-free piston compressor, which belongs to the technical field of compressor equipment. Background technique [0002] Air compressor, that is, air compressor, air compressor is a kind of equipment used to compress gas. Air compressors are divided into two categories: speed type and volume type. Volume type air compressors include reciprocating type (such as: piston type) and rotary type (such as sliding vane type, screw type, rotor type). Most air compressors are reciprocating piston, rotating vane (vane) or rotating screw. The piston compressor is a positive displacement compressor, and its compression element is a piston, which reciprocates in the cylinder of the piston air compressor. According to the lubrication method, it can be divided into oil-lubricated air compressors and oil-free lubricated air compressors. [0003] The oil-piston air compressors used in the existing new energy field are m...
