Locomotive double air compressor control device

Abstract

The invention relates to the technical field of internal combustion engines, in particular to a control device for dual air compressors of a locomotive. The air circuit includes that the front end of air compressor one is connected to check valve one, and the front end of air compressor two is connected to check valve two. The air compressor one and air compressor two are connected in parallel to the input of the water separator, and the water separator The output of the main air cylinder is connected to the input of the main air cylinder, the output of the main air cylinder is connected to the safety valve and the filter, an air dryer is connected in series between the safety valve and the filter, an automatic drain valve is connected to the bottom of the water separator, and the main air cylinder One side of the main air cylinder is connected to an automatic drain valve two, the control ends of the automatic drain valve one and the two are connected in parallel to the solenoid valve, and the other side of the main air cylinder is connected to the pressure switch and the pressure transducer in sequence; the logic control circuit includes logic control device. The locomotive double air compressor control device has a simple structure and has achieved the expected function in actual work, which has improved the guarantee for the operation of the SDA2 locomotive overseas.

Description

technical field [0001] The invention relates to a control device, in particular to a control device for dual air compressors of a locomotive. Background technique [0002] The original locomotive double air compressor control directly drives the air compressor to work through the switch signals under different pressure values. When the pressure switch is damaged and other failures occur, it cannot effectively guarantee the braking air of the locomotive. At the same time, the fixed sequence of the air compressor work, and cannot guarantee the same utilization rate of the two air compressors, which increases the difficulty of maintenance. Contents of the invention [0003] The present invention aims to solve the above defects, and provides a control device for locomotive dual air compressors. [0004] In order to overcome the defects in the background technology, the technical solution adopted by the present invention to solve the technical problem is: the locomotive double...
