Operation control method of air source system in rail transit

Abstract

The invention relates to a track traffic air source system operation control method. The operation state of an air compressor is controlled according to exhaust opening pressure of an air source device and temperature of lubricating oil in an oil gas barrel, and under the premise that exhaust pressure of the air source device is guaranteed, the emulsion caused by the fact that temperature of the lubricating oil is too low is avoided. The air compressor carries out loading or no-loading or halting timely according to situations, and healthy operation of an air source system is achieved at the lowest cost. After the method is used, the operation rate of the track traffic air source system is improved to a certain degree, operation time is prolonged, so that oil temperature in the oil gas barrel is raised quickly, moisture in compressed air exists in the gas state, and along with exhausting of the compressed air, the emulsion caused by the fact that the compressed air is mixed with the lubricating oil in the oil gas barrel is avoided. Through example verification, the emulsion of the track vehicle air source system is solved after the method is used.

Description

technical field [0001] The invention relates to a method for controlling the operation of a rail transit wind source system. Background technique [0002] The operating state of the existing air source system for rail is generally a discontinuous duty system, and the work rate is generally between 15% and 55%. Time is down. When the air compressor is in normal operation, it continuously inhales air containing moisture. When the temperature inside the machine is lower than the dew point temperature of the compressed air pressure, the water vapor in the air will be condensed to form liquid water, and the liquid water will stay in the oil and gas barrel and mix with the lubricating oil. At the same time, due to the impact and stirring of the compressed air flow, the lubricating oil is emulsified and deteriorated. Under normal working conditions, the operating temperature of the system should be higher than the dew point temperature of the compressed air, and no condensed wate...

Problems solved by technology

However, the air compressor unit of the air source system of rail vehicles has a low operating rate, and because it is installed under the vehicle, the unit will be affected by the airflow to accelerate heat dissipation when the vehicle is running, so that it cannot quickly establish a suitable oil temperature, which is easy to form Lubricating oil emulsification
