Abstract

The application discloses an operation control method, system and an air compressor system. The method and the system are used for controlling the air compressor system of track locomotives. The total blast pressure of a total air cylinder is detected; when the total blast pressure changes, the total blast pressure change rate is calculated according to the change conditions of the total blast pressure, wherein the total blast pressure change rate comprises the total blast pressure rising rate and the total blast pressure descending rate; multiple actual operating rotating rates which successively descend are determined according to the maximum operation rotating rate of the air compressing device; a target rotating rate is selected from the multiple actual operating rotating rates according to the total blast pressure and total blast pressure changes and the air comprising device is controlled to operate at the target rotating rate; when the total blast pressure value reaches at the maximum operating pressure of the total air cylinder, the air compressing device is controlled to stop rotating. The technical scheme of the application can solve the problem of emulsification of lubricant due to short single operation time of an air compressor system.

Description

technical field [0001] The present application relates to the technical field of rail transit, and more specifically, relates to an operation control method, system and air compressor system. Background technique [0002] The air compressor is an important power equipment on the rail locomotive, which provides the wind source for the rail locomotive to decelerate and brake by outputting high-pressure gas. In order to ensure the safe operation of rail locomotives, the rated displacement of their air compressors is often designed based on ensuring sufficient air volume under extreme conditions. However, the air volume of rail locomotives in normal operation is very different from extreme conditions, that is, the air compressor only needs to work at a lower working rate to meet the normal needs of rail locomotives. In this case, lubricating oil The temperature often cannot meet the requirements of oil-water separation, and the inhaled water cannot be removed, resulting in the ...
