Description

System and method for charging starting air cylinder
Technical Field
The invention relates to the technical field of vehicles, in particular to a system and a method for charging a starting air cylinder.
Background
The starting mode of the locomotive diesel engine mainly comprises an air starting mode and an electric starting mode, wherein the air starting mode is a starting mode of driving an air starting motor to rotate by relying on compressed air so as to drive the diesel engine to rotate. In order to start with air, the locomotive is equipped with a starting reservoir to ensure the air supply is sufficient and stable. Conventional diesel locomotives are limited in their battery capacity and require an auxiliary air supply system including an auxiliary compressor to charge the starting reservoir. However, with the advent of powered battery powered locomotives, the locomotives have been able to use the power battery to meet the long term operation of the main air compressor, and therefore a new locomotive starting reservoir charging control method is needed to develop the performance of the locomotives.
FIG. 1 shows a schematic diagram of a prior art system for charging a starting reservoir. In fig. 1: 1-main air compressor, 2-hose, 3-dryer, 4-filter, 5-minimum pressure valve, 6-safety valve, 7-total air cylinder, 8-auxiliary compressor, 9-unloading valve, 10-check valve, 11-pressure sensor and 12-starting air cylinder.
As shown in fig. 1, an existing air-starting internal combustion locomotive is generally equipped with two sets of air source systems, one set is a main air source system for supplying air to the whole locomotive, and the other set is an auxiliary air source system dedicated to charging air of a starting air cylinder. The main air source system consists of a main air compressor 1, a dryer 3, a filter 4 and the like, and can output dry and clean compressed air. The auxiliary air source system is composed of an auxiliary compressor 8, a check valve 10, a safety valve 6, a pressure sensor 11 and the like.
When the locomotive needs to be started, the auxiliary compressor 8 starts to operate, the starting air cylinder 12 is charged with air, and the operation is stopped when the pressure of the starting air cylinder 12 reaches a target value.
When the locomotive normally runs, the compressed air output by the main air cylinder 7 partially enters the starting air cylinder 12, and because the air tightness of the starting air cylinder 12 is far better than that of the main air cylinder 7, after the locomotive stops running, the compressed air in the starting air cylinder 12 can be stored for a long time and is reserved for next starting.
When the locomotive is started in a windless state, the auxiliary compressor 8 needs to be used for charging air to the starting air cylinder 12, and the following two problems can be caused:
1. the start-up waiting time is too long: limited by the air supply capacity of the auxiliary compressor 8, it often takes more than 30 minutes to start the air cylinder 12 to charge to the target value.
2. The cleanliness of the auxiliary air source is not high: the auxiliary air source is limited by the space and the cost of the locomotive, the drier and the filter which are in the same grade as the main air source are difficult to install additionally, the cleanliness of the compressed air is not high, and the compressed air can influence pneumatic equipment in an air starting system in a long-term application process.
In addition, patent application publication No. CN113931775A provides a cylinder system for starting a diesel engine, in which an auxiliary compressor is used as a backup for a main air compressor, a starting cylinder is used as a backup for a main cylinder, and the compressed air of the starting cylinder is used to quickly help the main cylinder build up pressure at the beginning of charging the main cylinder. The scheme still has similar problems in the two aspects on the charging of the starting air cylinder.

In the embodiment of the invention, compared with the scheme in the prior art, the device of an auxiliary air source part is omitted, and the action valve 7 and the electromagnetic valve 9 are added to assist in realizing the quick air charging of the starting air cylinder 12.
When the diesel engine needs to start, the locomotive detects the pressure of the starting air cylinder 12 through the pressure sensor 11, judges whether the pressure of the starting air cylinder 12 can reach a start condition, if the pressure does not reach the start condition, the main air compressor 1 starts to operate, the electromagnetic valve 9 is powered on at the moment, a pipeline which is directly communicated with the starting air cylinder 12 is opened, when compressed air passes through the electromagnetic valve 9, a part of compressed air can reach a pre-control interface of the action valve 7 through the pre-control pipeline, the action valve 12 is closed, the pipeline which is communicated with the main air cylinder 8 is disconnected, and the main air compressor 1 only fills air to the starting air cylinder 12.
