Problems solved by technology

However, the current method cannot accurately judge the working conditions with low passenger flow after the official operation. The vehicle enters the idling mode under non-low passenger flow conditions, which will increase the idling loss of the air compressor and cannot effectively prevent lubricating oil The effect of emulsification will not only increase the operating cost, but also shorten the service life of the air compressor
[0007] Aiming at the problem of preventing the poor emulsification effect of air compressor lubricating oil in related technologies, no effective solution has been proposed so far

Abstract

The invention discloses a control device, system and method for preventing lubricating oil of an air compressor from being emulsified. The control system for preventing the lubricating oil of the aircompressor from being emulsified comprises a main air compressor, an auxiliary air compressor and two control devices for preventing the lubricating oil of the air compressor from being emulsified. One control device for preventing the lubricating oil of the air compressor from being emulsified is arranged on the main air compressor and connected with the main air compressor. The other control device for preventing the lubricating oil of the air compressor from being emulsified is arranged on the auxiliary air compressor and connected with the auxiliary air compressor. The main air compressorand the auxiliary air compressor cooperate to compress air, and air is supplied to vehicles; and at the time frame that the vehicle air consumption is low and the start frequency of the air compressoris low, when the main air compressor and the auxiliary air compressor do not need to supply air to vehicles, the main air compressor is controlled to enter an idling state to increase the temperatureof the lubricating oil, when the main air compressor is started at the next time, the temperature of the lubricating oil in the main air compressor is in a high temperature state, and therefore the temperature of compressed air can be rapidly improved, and the risk that the lubricating oil is emulsified is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of rail transit, and further relates to a control device, system and method for preventing lubricating oil emulsification of an air compressor, and in particular to a control device for preventing lubricating oil emulsification of a screw air compressor by using an idle running device, systems and methods. Background technique [0002] The air compressor of the vehicle (ie: air compressor) due to factors such as short single operation time and / or long start-up time intervals, etc., will cause the lubricating oil temperature to be low when the air compressor is started, and the air compressor is compressing the air. Liquid water is easy to precipitate during the process, and due to the short single operation time, the air compressor cannot fully bring the precipitated liquid water out of the air compressor. The normal lubrication effect of the machine. [0003] At this stage, the principle that the ...
