Embodiment Construction

[0014] A method for controlling the start and stop of dual air compressors on a locomotive, comprising connecting an air pressure regulator to the first main air cylinder, the air pressure regulator is connected to the locomotive microcomputer, and the air pressure regulator and the control system in the locomotive microcomputer are jointly To control the start and stop of the air compressor, the information transmission process of the air pressure regulator is as follows: use the pressure sensor inside the air pressure regulator to take pressure sampling → convert the circuit → switch the pressure of the first main air cylinder through its internal photoelectric relay The signal is transmitted to the locomotive microcomputer, and the air pressure regulator pre-sets four pressure levels of A, B, C, and D for the first master air cylinder, and the control system in the locomotive microcomputer automatically implements the control strategy according to the pressure value of the fi...

Abstract

The invention relates to the field of compressor control methods, and in particular relates to a start-stop control method for double air compressor of a locomotive. The method comprises the following steps: connecting an air pressure regulator to a first main air cylinder; connecting the air pressure regulator to a locomotive microcomputer; and utilizing the air pressure regulator and a control system arranged in the locomotive microcomputer to corporately control the start-stop of the air compressors. When a locomotive main air cylinder is free from pressure,two air compressors are simultaneously started to work; after the pressure in the main air cylinder reaches a preset pressure, one of the air compressors is stopped and the other air compressor continues to work till the pressure in the main air cylinder meets demand, so as to prolong the working time of the air compressors, reduce the start-stop times of the air compressors and cause the interior of the air compressors to achieve a temperature at which water can be vaporized.

Description

technical field [0001] The invention relates to the field of compressor control methods, in particular to a start-stop control method for a locomotive dual-air compressor. Background technique [0002] For locomotives equipped with two air compressors, the start-stop control method of the original air compressor is basically to start and stop the two air compressors at the same time. When the cylinder pressure reaches the specified pressure, the working pump wind time is short. Under the same downtime condition, the number of start and stop times of the air compressor is relatively large, and the failure rate is relatively increased. Control the contact of the air compressor drive motor to power on and off The burnout failure rate of the contacts of the device (switch) will also increase relatively; the second is that when the screw air compressor is working to pump air, oil, gas, and water are mixed together, and the water separation must be achieved after the inside of the...
