Background Art

[0002] The air supply system plays a vital role in rail vehicles, providing compressed air for air brake systems and air suspensions, among other functions. Piston rings, as key sealing components in the air compressors of these systems, can wear out over time, directly impacting the system's sealing performance and pumping efficiency.

[0003] In the related art, the wear condition of the piston ring requires maintenance personnel to disassemble the air compressor for identification and confirmation, which has high maintenance costs. In addition, the wear condition of the piston ring can usually only be identified after the air compressor loses its air supply capacity due to piston ring wear, which can easily lead to accidents.

[0008] Optionally, detecting the wear condition of the piston ring according to the time includes: comparing the time with a first preset time; if the time is less than or equal to the first preset time, the wear condition of the piston ring is suitable for normal use.

[0010] Optionally, the first preset time is the time it takes to pump air into the air reservoir of the air source system and increase the air pressure of the air reservoir from a first preset pressure to a second preset pressure when using a piston ring that has been worn to a limit.

[0011] Optionally, when it is detected for the first time that the wear of the piston ring exceeds the limit, the number of records is one; thereafter, each time it is detected that the wear of the piston ring exceeds the limit, the number of records increases by one.

[0012] Optionally, when the number of records reaches a preset value, a piston ring wear warning is issued.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0023] According to the first aspect of the present invention, Figure 1 As shown, a method for detecting piston ring wear of an air source system is provided, comprising: Collecting the time of pumping air into the air cylinder of the air source system; The wear condition of the piston ring is detected based on the time.

[0024] Through the above method, the wear of the piston ring can be detected according to the time of pumping air into the air cylinder. The sealing performance of piston rings with different degrees of wear will be different, and the time of pumping air into the air cylinder will also be correspondingly different. Through the above method, the wear of the piston ring can be understood in real time without disassembling the air source system, and the piston ring wear can be identified in time, which to a certain extent ensures the normal operation of the air source system and the safety of rail vehicles.

[0025] In some embodiments of the present invention, collecting the time for pumping air into the air cylinder of the air source system includes collecting the time t when the air pressure of the air cylinder changes from a first preset air pressure P1 to a second preset air pressure P2.

[0026] In some embodiments of the present invention, the detecting of the wear condition of the piston ring according to the time includes: comparing the time t with a first preset time t1; if the time t is less than or equal to the first preset time t1, the wear condition of the piston ring can be used normally.

[0027] In some embodiments of the present invention, detecting the wear of the piston ring based on the time includes: comparing the time t with a first preset time t1; if the time t is greater than the first preset time t1, the wear of the piston ring exceeds a limit.

[0028] In some embodiments of the present invention, in preliminary experiments, air was pumped into the air reservoir of the air source system while using a piston ring that was worn to its limit. The time it took for the air pressure in the air reservoir to increase from a first preset pressure P1 to a second preset pressure P2 was recorded as the first preset time t1. The "maximum wear" of the piston ring refers to the maximum degree of wear at which the piston ring can operate normally. Exceeding this wear level will result in slower pumping or even leakage.

[0029] In some embodiments of the present invention, when the piston ring wear is first detected to have exceeded the limit, the number of recordings n is one, i.e., n=1. Each subsequent detection of piston ring wear exceeding the limit increases the number of recordings n by one, i.e., n=n+1. When the number of recordings n reaches a preset value n0, i.e., n≥n0, a piston ring wear warning is issued. Due to potential errors, in some embodiments, the warning is not issued upon the first detection of t≥t1, but rather when the number of recordings n reaches the preset value n0 to reduce false positives. The preset value n0 should not be set too low, thereby preventing false positives, nor too high, thereby preventing a timely warning. In some embodiments, the preset value n0 is set between 3 and 5.

[0030] like Figure 4Figure 1 shows a pressure-time curve for pumping air when the piston ring is normally worn, according to one embodiment of a method for detecting piston ring wear in an air source system according to the present invention. In preliminary experiments, curve l1 shows the corresponding relationship between pressure and time when a piston ring is worn to its limit. This curve records the time t1 for the pressure to increase from a first preset pressure P1 to a second preset pressure P2. As shown by curve l, during the current pumping process, the time t for the pressure to increase from the first preset pressure P1 to the second preset pressure P2 is less than the first preset time t1, indicating that the air cylinder's sealing performance is better than when the piston ring is worn to its limit. Therefore, it can be assumed that the piston ring wear condition at this point is suitable for normal use.

[0031] like Figure 5 Figure 1 shows a pressure-time curve for inflation when piston ring wear exceeds the limit, according to one embodiment of a method for detecting piston ring wear in an air source system according to the present invention. In preliminary experiments, curve l1 shows the relationship between pressure and time when using a piston ring that has reached its limit of wear. This curve records the time t1 for the pressure to increase from a first preset pressure P1 to a second preset pressure P2. As shown by curve l, during the current inflation process, the time t for the pressure to increase from the first preset pressure P1 to the second preset pressure P2 is greater than the first preset time t1, indicating that the air cylinder's sealing performance is worse than when the piston ring is worn to its limit. It can be considered that the piston ring wear may have exceeded the limit at this point.

[0032] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the piston ring wear detection method of the air source system includes the following steps: Collect the time t1 when the air pressure in the air reservoir changes from the first preset air pressure P1 to the second preset air pressure P2 when the piston ring is worn to the limit state; Real-time acquisition of the time t that the air source system pumps air into the air reservoir during operation; Compare the sizes of t and t1; When t≤t1, the piston ring wear is normal, and the time t of the air source system pumping air into the air reservoir during operation continues to be collected in real time; When t>t1, the number of records n=n+1; Determine whether the number of records n reaches the preset value n0; When n<n0, continue to collect the time t of the air source system pumping air into the air cylinder during operation in real time; When n≥n0, a piston ring wear warning is issued.

[0033] In some embodiments, if the inflation time t exceeds the first preset time t1, it may be due to piston ring wear exceeding the limit, resulting in poor sealing, or it may be due to a leak in the air cylinder. During routine maintenance, air cylinder leaks are easy to troubleshoot, while piston ring wear requires disassembly of the air compressor to identify. Therefore, after receiving a piston ring wear warning, maintenance personnel should first check for air cylinder leaks. If the air cylinder is leak-free, they should then disassemble the air compressor to replace the piston rings.

[0034] According to a second aspect of the present invention, a computer-readable storage medium is provided, in which computer-executable instructions are stored. When the computer-executable instructions are executed by a processor, they are used to implement the piston ring wear detection method of the wind source system described in the first aspect of the present invention.

[0035] According to a third aspect of the present invention, a computer program product is provided, comprising a computer program, which, when executed by a processor, implements the piston ring wear detection method for the air source system according to the first aspect of the present invention.

[0036] According to a fourth aspect of the present invention, there is provided a wind source system comprising: a processor and a memory, wherein the memory is used to store a computer program, and the processor is used to implement the piston ring wear detection method for the wind source system described in the first aspect of the present invention when executing the computer program stored in the memory.
