Single-cylinder compressor provided with oil-feed pump

Abstract

The invention discloses a single-cylinder compressor provided with an oil-feed pump. The single-cylinder compressor comprises a single-cylinder compressor body and a circulating oil-feed pump; the front surface of the single-cylinder compressor body is provided with an air charging cylinder; the rear surface of the single-cylinder compressor body is provided with an air discharging cylinder; the left surface of the single-cylinder compressor body is provided with an axle hole plate; an internal air pressing device is arranged inside the single-cylinder compressor body and sleeves an externally-connected input shaft; a crank type air pressing mechanism is also arranged inside the single-cylinder compressor body; the crank type air pressing mechanism and the internal air pressing device are installed in a manner of being matched with each other; the internal air pressing device and the crank type air pressing mechanism form an upper region and a lower region inside the single-cylinder compressor body; the upper region and the lower region are each internally submerged in cooling oil liquid; the circulating oil-feed pump is fixedly installed on the axle hole plate through a screw; the circulating oil-feed pump and the axle hole plate are sealed; an oil sucking hole of the circulating oil-feed pump is positioned inside the upper region; and an oil outlet of the circulating oil-feed pump is positioned inside the lower region. The single-cylinder compressor disclosed by the invention has the beneficial effects that the circulating speed of oil liquid motion is high, a good heat dissipation effect is realized and the continuous working time is long.

Description

technical field [0001] The invention relates to a single cylinder compressor with an oil inlet pump. Background technique [0002] The working pressure range of the nitrogen compressor is 300Mpa for liquid and 90Mpa for gas. According to the shaft type, it is divided into single-shaft multi-stage type and double-shaft four-stage type. The single-cylinder compressor described herein is a nitrogen compressor. Its main features are: large working pressure range, wide flow range, easy control, safe operation, etc. At present, the development of nitrogen compressors is gradually developing in the direction of multi-stage to improve the performance and pressurization capacity of nitrogen compressors. This multi-stage nitrogen compressor is generally based on the principle and basis of single-cylinder nitrogen compressors. Therefore, the overall performance and development direction of the single-cylinder compressor still affect the overall development of the nitrogen compressor ...

AI Technical Summary

Problems solved by technology

[0003] Existing single-cylinder compressors have dense internal components and often generate high temperatures during pressurization. Moreover, once this type of single-cylinder compressor is started, the continuous working time is usually more than 16 hours, and the cylinder body heats up very seriously. To alleviate this situation, Usually, the way we use is to add lubricating oil between the internal components of the compressor, and submerge and cover the inside of the compressor to a certain extent, so that the frictional heat generated during the operation of the nitrogen compressor is absorbed by the oil, realizing the protection of the compressor. The purpose of cooling the nitrogen compressor; but it is not enough to add oil, the local area of ​​the nitrogen compressor is extremely hot, and these oils basically do not flow after being added, which results in high oil temperature in some areas and oil in some areas. The temperature of the liquid is low, resulting in uneven heat dissipation, and the oil stays in place for a long time. Although the heat is absorbed by the oil, it is difficult for the oil itself to dissipate the heat, which will cause the heat dissipation effect to be unsatisfactory.
