Oil leakage detection is carried out on the ferroalloy metallurgy hydraulic system through combination of the oil pumping state, the oil level and the oil pressure of the oil pump of the hydraulic system, and compared with a traditional mode that single-index oil leakage detection is carried out only according to the oil pressure or the oil level, the oil leakage condition in the ferroalloy metallurgy hydraulic system can be accurately detected; when oil leakage detection is carried out, oil level value collection lasts for a preset period of time, and when the oil level value collected in the period of time represents that the oil level in the oil tank is in a descending trend, it is judged that the oil leakage situation occurs; and the situation that the oil leakage type of the oil tank cannot be accurately judged due to the lowest oil level change caused by excessive oil pumping of the oil pump or oil supplementation of the oil tank is avoided. The objective of the invention is to solve the problem of how to accurately detect outer leakage and inner leakage of the ferroalloy metallurgy hydraulic system.

Description

Technical Field

[0001] The present application relates to the technical field of ferroalloy metallurgical hydraulic system detection, and in particular to an oil leakage detection method, an oil leakage detection system and a readable storage medium for a ferroalloy metallurgical hydraulic system. Background Art

[0002] In the ferroalloy smelting production process, it is very important to prevent the ferroalloy metallurgical hydraulic system from leaking oil. If the pipeline or oil circuit leaks, it will cause the ferroalloy metallurgical hydraulic system to lose pressure, and the motor will lose control and the oil will leak, which is also likely to cause a fire. Therefore, timely detection of oil leakage is crucial to safe production.

[0003] In the related technical scheme, the Chinese patent with application number 202022170038.7 discloses a hydraulic station pipeline oil leakage detection device. Referring to the records in its specific implementation method, it can be seen that it mainly detects the oil leakage of the pipeline in the hydraulic station by means of oil pressure detection. When the pipeline pressure changes, the position of the pipeline pressure change is judged as the location of the oil leakage fault.

[0004] However, the applicant discovered during the process of conceiving and implementing the present application that, for ferroalloy metallurgical hydraulic systems, oil leakage is usually divided into internal leakage and external leakage. Internal leakage refers to leakage inside the hydraulic valve assembly and the oil cylinder, but the oil is still in the oil tank. Therefore, after internal leakage occurs, the oil level in the oil tank will not decrease, and it will only cause the oil pump to be unable to establish oil pressure, or the oil pressure will not reach the upper limit; external leakage is oil leakage to the outside of the oil tank. At this time, the oil pump can establish oil pressure but the oil level in the oil tank will decrease.

[0005] In view of this, the oil pressure leakage detection method provided in the above scheme will not be able to accurately judge the oil leakage phenomenon when external leakage occurs in the ferroalloy metallurgical hydraulic system. In addition, the oil cylinder in the ferroalloy metallurgical hydraulic system operates frequently, and the oil pressure will change multiple times in a short period of time. It is easy to misjudge only by oil pressure detection. Therefore, this application proposes an oil leakage detection method for a ferroalloy metallurgical hydraulic system to accurately detect external and internal leakage of the ferroalloy metallurgical hydraulic system.

[0006] The above contents are only used to assist in understanding the technical solution of the present application and do not constitute an admission that the above contents are prior art. Summary of the invention

[0007] The main purpose of the present application is to provide an oil leakage detection method for a ferroalloy metallurgical hydraulic system, aiming to solve the problem of how to accurately detect external leakage and internal leakage of a ferroalloy metallurgical hydraulic system.

[0008] To achieve the above-mentioned purpose, the present application provides a method for detecting oil leakage in a ferroalloy metallurgical hydraulic system, the method comprising the following steps:

[0016] Optionally, the step of judging whether the oil level in the oil tank is in a downward trend according to the second oil level value set and the first oil level value comprises:

[0017] determining whether the oil level value in the second oil level value set is less than the first oil level value;

[0018] If yes, it is judged that the oil level is in a downward trend;

[0019] Otherwise, it is determined that the oil level is not in a downward trend.

[0020] Optionally, the step of judging whether the oil level in the oil tank is in a downward trend according to at least two oil level values ​​in the second oil level value set and / or the first oil level value comprises:

[0021] Determine whether the oil level value obtained at the previous moment in the second oil level value set is greater than the oil level value obtained at the next moment; or,

[0022] Determine whether any oil level value in the second oil level value set is lower than the first oil level value;

[0023] If so, determining that the oil level in the oil tank is in a downward trend;

[0024] Otherwise, it is determined that the oil level in the oil tank is not in a downward trend.

[0025] Optionally, it is characterized in that the oil leakage detection method further comprises:

[0026] If the oil level in the oil tank is not on a downward trend, a warning indicating that there is an internal leakage risk in the hydraulic system is output to the backend terminal;

[0027] If the oil level in the oil tank is on a downward trend, a warning indicating the risk of leakage in the hydraulic system is output to the backend terminal.

[0028] Optionally, before the step of collecting at least one current oil level value within the second preset time period to form a second oil level value set, the step further includes:

[0029] determining whether the first oil level value is greater than or equal to a reference oil level value corresponding to the set oil pressure threshold;

[0030] If so, a prompt message indicating that there is a risk of internal leakage in the hydraulic system is output to the background terminal.

[0031] Optionally, the oil leak alarm process includes at least one of the following:

[0033] Output the prompt information that the hydraulic system has the risk of internal leakage to the background terminal;

[0034] Output a warning message to the background terminal indicating that there is a risk of leakage in the hydraulic system.

[0035] In addition, to achieve the above-mentioned purpose, the present application also provides an oil leakage detection system, comprising: a memory, a processor, and an oil leakage detection program for a ferroalloy metallurgical hydraulic system stored in the memory and executable on the processor, wherein the oil leakage detection program for the ferroalloy metallurgical hydraulic system, when executed by the processor, implements the steps of the oil leakage detection method for the ferroalloy metallurgical hydraulic system as described in any one of the above items.

[0036] In addition, to achieve the above-mentioned purpose, the present application also provides a server, which includes: a memory, a processor, and an oil leakage detection program for a ferroalloy metallurgical hydraulic system stored in the memory and runnable on the processor, and when the oil leakage detection program for the ferroalloy metallurgical hydraulic system is executed by the processor, the steps of the oil leakage detection method for the ferroalloy metallurgical hydraulic system as described in any one of the above items are implemented.

[0037] In addition, to achieve the above-mentioned purpose, the present application also provides a computer-readable storage medium, on which is stored an oil leakage detection program for a ferroalloy metallurgical hydraulic system. When the oil leakage detection program for a ferroalloy metallurgical hydraulic system is executed by a processor, the steps of the oil leakage detection method for a ferroalloy metallurgical hydraulic system as described in any of the above items are implemented.

[0038] This application has at least the following beneficial effects:

[0039] 1. The oil leakage detection of ferroalloy metallurgical hydraulic system is carried out by combining the pumping state of the hydraulic system oil pump, the oil level and the oil pressure. Compared with the traditional oil leakage detection method that only uses a single indicator of oil pressure or oil level, it can accurately detect the oil leakage in the ferroalloy metallurgical hydraulic system;

[0040] 2. When conducting oil leakage detection, the oil level value is collected for a preset period of time. When the oil level value collected during this period indicates that the oil level in the fuel tank is on a downward trend, it is determined that an oil leakage has occurred, so as to avoid inaccurate judgment of the type of oil tank leakage caused by changes in the minimum oil level due to excessive oil extraction by the oil pump or oil replenishment in the fuel tank.

[0078] Output the prompt information that the hydraulic system has the risk of internal leakage to the background terminal;

[0079] Output a warning message to the background terminal indicating that there is a risk of leakage in the hydraulic system.

[0080] Based on the hardware architecture of the above-mentioned oil leakage detection system based on the ferroalloy metallurgical hydraulic system detection technology, an embodiment of the oil leakage detection method of the ferroalloy metallurgical hydraulic system of the present application is proposed.

[0081] Reference Figure 2 In a first embodiment, the oil leakage detection method of the ferroalloy metallurgical hydraulic system comprises the following steps:

[0082] Step S10, when the oil pump is in the oil pumping state, collecting the current oil pressure in the oil tank of the ferroalloy metallurgical hydraulic system after a first preset time interval;

[0083] In this embodiment, when the system detects that the oil pump is placed in the oil pumping state, it starts to wait for a preset time. During the preset time, as the oil in the oil tank is pumped into the accumulator and the hydraulic working element, the oil pressure in the oil tank will gradually increase. For the oil tank of the ferroalloy metallurgical hydraulic system where there is no oil leakage, it is assumed that the oil pressure in the oil tank reaches the set oil pressure upper limit after the first preset time, and the oil pressure at this time is collected as the current oil pressure for judgment.

[0084] In this embodiment, the first preset time period is associated with the time period required for the oil pressure in the oil tank to increase to a set upper limit of the oil pressure when the oil pump is in the oil pumping working state.

[0085] It should be noted that, in the ferroalloy metallurgical hydraulic system in the present embodiment, after the oil pump is placed in the oil pumping state for the first preset period of time, the oil level and oil pressure in the oil tank tend to be stable, while in other states, the oil level and oil pressure in the oil tank are changing. Therefore, in the present embodiment, it is necessary to limit the oil pump of the ferroalloy metallurgical hydraulic system to be in the oil pumping state before performing oil leakage detection.

[0086] Step S20, when the current oil pressure is lower than the set oil pressure threshold associated with the first preset time period, obtaining the oil level value at the current moment as the first oil level value;

[0087] After collecting the current oil pressure, compare the current oil pressure with the set oil pressure threshold associated with the first preset time length to determine the size of the two. If the current oil pressure is lower than the set oil pressure threshold, obtain the oil level value in the fuel tank at the current moment to detect and identify oil leaks, and use it as the first oil level value.

[0088] In this embodiment, for the oil tank of the ferroalloy metallurgical hydraulic system without oil leakage, after the oil pump has been in the oil pump state for the first preset period of time, the oil pressure inside the oil tank should be at the set highest point, and the oil level inside the oil tank should be at the set lowest point. If oil leakage occurs, the oil pressure in the oil tank will be lower than the set oil pressure threshold. The specific type of oil leakage, whether it is external leakage or internal leakage, is related to the size relationship between its oil level and the reference oil level value of the set lowest point.

[0089] It should be noted that in previous technical solutions, we set a reference oil level value as the judgment threshold. If the first oil level value is lower than the reference oil level value, it means that the oil may leak out of the fuel tank, causing the first oil level value to be lower than the reference oil level value corresponding to no oil leakage, and there is a risk of leakage from the fuel tank.

[0090] However, after testing, it was found that simply relying on an oil level threshold as a leakage detection, that is, when the oil tank leakage alarm is issued when the first oil level value is lower than the reference oil level value, there will be a large number of false alarms during the actual operation of the system. That is, when the system detects a leakage alarm, the maintenance personnel rush to the hydraulic system oil tank to check and find no leakage.

[0091] The main reasons are the following two aspects:

[0092] On the one hand, the oil pressure due to oil leakage in the fuel tank cannot reach the set oil pressure threshold. After the oil pump has pumped oil for a first preset period of time, it detects that the oil pressure does not reach the set oil pressure threshold and will continue pumping oil for a short period of time before stopping, thereby causing the oil level in the fuel tank to further decrease. However, due to oil leakage in the fuel tank, the oil pressure still cannot reach the set oil pressure threshold. At this time, regardless of whether there is leakage, the first oil level value collected by the system at the current moment is lower than the reference oil level value.

[0093] On the other hand, the ferroalloy metallurgical hydraulic system will also replenish oil into the oil tank during the oil pump process. When the time of collecting the first oil level value happens to be before the oil replenishment action or occurs at the same time as the oil replenishment action, the first oil level value will not be lower than the reference oil level value, but at this time there may be oil leakage in the oil tank.

[0094] Step S30, collecting at least one current oil level value within a second preset time period to form a second oil level value set;

[0095] Step S40, after obtaining the second oil level value set, judging whether the oil level in the oil tank is in a downward trend according to the second oil level value set and / or the first oil level value, triggering an oil leakage alarm process.

[0096] Furthermore, in order to solve the above problem, the present embodiment further proposes to collect at least one oil level value within a preset period of time, obtain an oil level value set consisting of a single or multiple oil level values, and comprehensively judge whether the oil level in the oil tank is in a downward trend based on the oil level value set and / or the first oil level value. At this time, the oil pump no longer pumps the oil in the oil tank to other components, and the oil level in the oil tank should not drop in theory if there is no external leakage. Therefore, if the collected oil level value set indicates that the oil level in the oil tank is in a downward trend, it is judged that the oil tank is leaking externally, triggering the oil leakage alarm process. If it is not in a downward trend, it is judged that the oil tank is leaking internally.

[0097] In addition, whether the oil level in the fuel tank is in a downward trend can be accurately judged regardless of whether oil refilling occurs in the fuel tank. This is because even if oil refilling occurs in the fuel tank and causes the first oil level value to be not lower than the reference oil level value, the internal oil level of the fuel tank will still show an overall downward trend due to external oil leakage. This can also overcome the problem of changes in the minimum oil level after oil refilling in the fuel tank.

[0098] Optionally, the second preset time length can be set to 6s.

[0099] In the technical solution provided in the present embodiment, the oil leakage detection of the ferroalloy metallurgical hydraulic system is carried out by combining the oil pumping state of the hydraulic system oil pump, the oil level and the oil pressure. Compared with the traditional oil leakage detection method that only performs a single indicator based on the oil pressure or the oil level, the oil leakage in the ferroalloy metallurgical hydraulic system can be accurately detected; and when performing oil leakage detection, the oil level value is collected for a preset period of time. When the oil level value collected during this period of time indicates that the oil level in the oil tank is on a downward trend, it is judged that an oil leakage occurs, thereby avoiding the inability to accurately judge the type of oil leakage in the oil tank due to the change of the minimum oil level caused by excessive oil pumping by the oil pump or oil filling in the oil tank.

[0100] Second embodiment

[0101] Reference Figure 3 Based on the first embodiment, in this embodiment, the oil level value in the second oil level value set is single or multiple, and the step S40 specifically includes:

[0102] Step S41, when the oil level value in the second oil level value set is a single one, judging whether the oil level in the oil tank is in a downward trend according to the second oil level value set and the first oil level value;

[0103] Step S42: when there are multiple oil level values ​​in the second oil level value set, judging whether the oil level in the oil tank is in a downward trend according to at least two oil level values ​​in the second oil level value set and / or the first oil level value.

[0104] In this embodiment, two methods for judging the oil level decreasing trend under two situations are provided.

[0105] 1. When the system collects only a single oil level value to form a second oil level value set within a second preset time period, a comparison is made between the second oil level value set and the first oil level value collected previously to determine whether the oil level in the fuel tank is in a downward trend.

[0106] This method aims to solve the situation where the oil level value drops due to excessive oil pumping, causing the first oil level value to be lower than the reference oil level value. That is, the oil level value is collected again within the period after the first oil level value is collected, and the relationship between the two collected values ​​is judged to determine whether the oil level in the tank is in a downward trend. Only one collection action needs to be added to realize the judgment of oil level drop, which is suitable for detection systems that need to reduce computing power overhead.

[0107] 2. When the system collects multiple oil level values ​​within a second preset time period to form a second oil level value set, a comparison is performed based on at least two oil level values ​​and / or the first oil level value collected previously to determine whether the oil level in the fuel tank is in a downward trend.

[0108] This method can be applied to the situation where oil replenishment occurs in the oil tank and the first oil level value is not lower than the reference oil level value, and it can also be applied to the situation where the oil level value drops due to excessive oil pumping and the first oil level value is lower than the reference oil level value. That is, the oil level value is collected multiple times within a period of time after the first oil level value is collected, and whether the oil level in the oil tank is in a downward trend is judged based on the oil level values ​​collected these times.

[0109] Furthermore, in this embodiment, step S41 includes:

[0110] Step S411, determining whether the oil level value in the second oil level value set is smaller than the first oil level value;

[0111] Step S412: If yes, it is determined that the oil level is in a downward trend;

[0112] Step S413: otherwise, it is determined that the oil level is not in a downward trend.

[0113] Furthermore, in this embodiment, step S42 includes:

[0114] Step S421, determining whether the oil level value obtained at the previous moment in the second oil level value set is greater than the oil level value obtained at the next moment;

[0115] Alternatively, step S422, determining whether any oil level value in the second oil level value set is smaller than the first oil level value;

[0116] Step S423: if yes, determine that the oil level in the oil tank is in a downward trend;

[0117] Step S424: otherwise, it is determined that the oil level in the oil tank is not in a downward trend.

[0118] It should be noted that, in the case where multiple oil level values ​​constitute the second oil level value set, the downward trend of the oil level can be judged only by the change of the oil level values ​​in the second oil level value set, that is, whether the oil level value obtained at the previous moment is greater than the oil level value obtained at the next moment. If there is an oil leak in the oil tank, the oil level value collected at the next moment will be lower than the oil level value collected at the previous moment, so that the oil level values ​​in the second oil level value set show a downward trend.

[0119] Alternatively, the oil level value in the second oil level value set can be compared with the first oil level value. Theoretically, when the oil tank is not leaking, if any oil level value in the second oil level value set will not be less than the first oil level value (it will be greater than when oil replenishment occurs), and once it is less than the first oil level value, it is judged that the oil level in the oil tank is on a downward trend, which means that there is a high probability of leakage in the oil tank.

[0120] In the technical solution provided in this embodiment, the oil level value set composed of a single or multiple oil level values ​​is used to follow different rules to judge the oil level decline trend, and the applicable scenarios of different rules are given. Appropriate judgment rules can be selected according to different situations to perform oil leak detection.

[0121] Third embodiment

[0122] Based on any of the above embodiments, in this embodiment, if the system determines that the oil level in the oil tank is not on a downward trend, due to the risk of internal leakage in the oil tank, the oil pressure will not be able to reach the set oil pressure threshold (i.e., lower than the set oil pressure threshold), but the oil has not flowed out, so the oil level will not drop, and a prompt is output to the background terminal that there is a risk of internal leakage in the hydraulic system; if the system determines that the oil level in the oil tank is on a downward trend, a prompt is output to the background terminal that there is a risk of external leakage in the hydraulic system.

[0124] Fourth embodiment

[0125] Reference Figure 4 Based on any of the above embodiments, in this embodiment, before step S30, the method further includes:

[0126] Step S50, determining whether the first oil level value is greater than or equal to a reference oil level value corresponding to the set oil pressure threshold;

[0127] Step S60: If yes, output a prompt message indicating that the hydraulic system has an internal leakage risk to the backend terminal.

[0128] In this embodiment, if the system determines that the first oil level value collected previously is greater than or equal to the reference oil level value, a prompt message indicating that there is a risk of internal leakage in the hydraulic system is output to the background terminal.

[0129] If the first oil level value is equal to the reference oil level value, but the current oil pressure is lower than the set oil pressure threshold, it means that the oil tank is leaking but the oil level has not dropped. It is judged that there is a risk of internal leakage in the oil tank, and a prompt message indicating that there is a risk of internal leakage in the hydraulic system is output to the background terminal.

[0130] If the first oil level value is higher than the reference oil level value, but the current oil pressure is lower than the set oil pressure threshold, the oil level may have increased due to oil tank refilling. In this case, it is still judged that there is a risk of internal leakage in the oil tank, and a prompt message indicating that there is a risk of internal leakage in the hydraulic system is output to the background terminal.

[0131] In addition, this embodiment also proposes a server, which includes: a memory, a processor, and an oil leakage detection program for a ferroalloy metallurgical hydraulic system stored in the memory and executable on the processor, wherein the oil leakage detection program for the ferroalloy metallurgical hydraulic system, when executed by the processor, implements the steps of the oil leakage detection method for the ferroalloy metallurgical hydraulic system as described in any one of the above items.

[0132] In addition, it can be understood by those skilled in the art that all or part of the processes in the method for implementing the above embodiment can be completed by instructing the relevant hardware through a computer program.
