Oil-free compressor used in locomotive

Abstract

The invention belongs to the technical field of air compressors, relates to an oil-free compressor used in a locomotive, in particular to an eccentric block-connecting rod reciprocating piston total oil-free lubricated compressor. The oil-free compressor comprises a motor, cylinders, a piston connecting rod assembly, an air valve assembly, cooling fan and the like, wherein, two cylinders are symmetrically arranged above and below a motor shaft, and can also be arranged at the left and the right of the motor shaft, and the two cylinders are coaxial. Connecting rods are sheathed on the motor shaft by a radial ball bearing and an eccentric block, small top end of each connecting rod is provided with two needle roller bearings with an one-side sealed structure, and a crank-connecting rod mechanism drives a piston to realize reciprocating motion in the cylinders. An air inlet valve, a valve plate and an air outlet valve are arranged between the cylinders and cylinder caps, and the valve plate is of a flat-sheet structure, and is provided with an inlet flow channel and an outlet flow channel. The cylinder caps are provided with air inlet chambers and air outlet chambers. The oil-free compressor has the advantages of oil saving, environmental protection, and simple operation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of air compressors, and relates to an oil-free locomotive compressor applied to a bow-raising system of an electric locomotive, in particular to an eccentric block-connecting rod reciprocating piston oil-free lubricating compressor. Background technique [0002] The oil-free compressor refers to a compressor that has no liquid lubricating oil in the moving mechanism of the compressor and in the cylinder. This kind of compressor can not pollute the working environment and gas equipment and its system during the working process, and can avoid the potential explosion hazard of the compressor due to the existence of hydrocarbons. It has the advantages of fuel saving, environmental protection, and simple operation and maintenance. Since the oil-free compressor came out in 1954, it has developed rapidly and has become one of the research hotspots in the compressor industry in recent years. At present, oil-free co...
