Oilless compressor and auxiliary compressor set

Abstract

The invention discloses an oilless compressor, and belongs to the field of electric locomotive equipment. The oilless compressor comprises a driving motor, a box body, a crankshaft, a cylinder and a piston module; the driving motor is connected with the box body; the cylinder is mounted in the box body; the crankshaft is connected with the driving motor, and is positioned in the box body of the compressor; the piston module is arranged in the cylinder, and is connected with the crankshaft; the oilless compressor is a single-cylinder structure; a cooling blade is mounted on the driving motor; a cylinder mounting ring base is arranged in the box body of the compressor, and is connected with the box body of the compressor through multiple cooling ribs; and a cylinder cover is arranged at the top of the box body of the compressor, and is provided with multiple first cooling fins. The oilless compressor realizes quick heat transfer of the cylinder, prevents excessive working temperature of the cylinder, guarantees the matching tightness between the cylinder and the piston module, and increases the displacement of the compressor to 0.08 m3 / min. The invention further discloses an auxiliary compressor set.

Description

technical field [0001] The invention relates to a compressor, specifically an oil-free compressor and an auxiliary compressor unit, belonging to the field of electric locomotive equipment. Background technique [0002] As an important national infrastructure, the development artery of the national economy, and a popular means of transportation, railways play a pivotal role in the modern logistics system. The construction of high-speed railways and the development of high-speed heavy-duty high-power AC electric locomotives are the focus of railway modernization development. In recent years, my country's high-speed railway construction has developed rapidly, and now it has the world's first high-speed railway mileage jump. [0003] During the operation of the high-speed rail, all electric locomotives need an auxiliary compressor unit to provide clean, clean and dry compressed air for the locomotive hoisting system and the main circuit breaker in advance, so as to ensure the st...

AI Technical Summary

Problems solved by technology

[0004] At present, the compressors in the auxiliary compressor units used on domestic DC drive electric locomotives usually adopt the traditional heat dissipation structure, and the heat dissipation effect is relatively poor, resulting in a small displacement of the compressor. The air volume is up to 0.07m3 / min, which cannot meet the use requirements under high load conditions
