DETAILED DESCRIPTION

[0037] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments 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 ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0038] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0039] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0040] The present invention is further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0041] Example:

[0042] See also Figure 1 and Figure 2 Based on the same inventive concept, the first embodiment of the present application discloses a multi-point oil supply equipment with oil mixing function, which includes a base 100, a fuel delivery structure 200, a lubricating oil delivery structure 300 and a joint structure 400. The fuel delivery structure 200 is installed on the base 100, and the lubricating oil delivery structure 300 is also installed on the base 100, and the lubricating oil delivery structure 300 is spaced apart from the fuel delivery structure 200. The joint structure 400 includes a mixing pipe 410 and a plurality of oil outlets 420 connected to the mixing pipe 410, and each oil outlet 420 is spaced apart. The mixing pipe 410 is connected to the fuel delivery structure 200 through a first pipe 430, and the mixing pipe 410 is connected to the lubricating oil delivery structure 300 through a second pipe 440.

[0043] The multi-point fuel supply equipment with oil mixing function disclosed in this embodiment realizes multi-point fuel output by accurately controlling the delivery ratio and flow rate of fuel oil and lubricating oil, thereby meeting the fuel demand under various complex working conditions.

[0044] In one embodiment, a first solenoid valve 230 and a first flow sensor 240 are disposed on the first pipeline 430 , and a second solenoid valve 330 and a second flow sensor 340 are disposed on the second pipeline 440 .

[0045] The first pipeline 430 is responsible for delivering the fuel from the fuel delivery structure 200 to the mixing pipeline 410. The first solenoid valve 230 is used to control the on and off of the fuel delivery to achieve accurate regulation of the fuel flow rate. The first flow sensor 240 monitors the fuel delivery flow rate in real time to ensure that the fuel is delivered according to the preset ratio and flow rate.

[0046] The second pipeline 440 is responsible for conveying the lubricating oil from the lubricating oil conveying structure 300 to the mixing pipeline 410. The second solenoid valve 330 is used to control the on and off of the lubricating oil conveying to achieve accurate regulation of the lubricating oil flow rate. The second flow sensor 340 monitors the delivery flow rate of the lubricating oil in real time to ensure that the lubricating oil is conveyed according to the preset ratio and flow rate.

[0047] By providing the first solenoid valve 230, the first flow sensor 240, the second solenoid valve 330 and the second flow sensor 340, the present invention can achieve accurate control of the delivery of fuel and lubricating oil, ensuring an accurate ratio of the mixed oil and a stable flow.

[0048] In one embodiment, the first solenoid valve 230 is provided in plurality, and the plurality of first solenoid valves 230 are arranged at intervals on the first pipe 430 . The second solenoid valve 330 is provided in plurality, and the plurality of second solenoid valves 330 are arranged at intervals on the second pipe 440 .

[0049] Three first solenoid valves 230 or second solenoid valves 330 are arranged on the same pipeline, and each first solenoid valve 230 or second solenoid valve 330 can independently control the flow of the medium in the pipe section where it is located. The three first solenoid valves 230 or second solenoid valves 330 can control different pipe sections respectively, so as to realize flexible regulation of the flow of the medium in the pipeline. For example, the flow rate or pressure of the medium can be controlled by adjusting the opening degree of a first solenoid valve 230 or second solenoid valve 330. When one of the first solenoid valves 230 or second solenoid valves 330 fails, the other first solenoid valves 230 or second solenoid valves 330 can still work normally, thereby ensuring the continuity and stability of the pipeline system. In addition, through redundant design (such as using three first solenoid valves 230 or second solenoid valves 330 instead of one or two), the risk of overall failure of the system due to failure of a single component can be reduced.

[0050] In one embodiment, a one-way valve 500 is disposed at the connection between the mixing pipe 410 and the first pipe 430 and the second pipe 440 , so that the fluid can only enter the mixing pipe 410 along the first pipe 430 and the second pipe 440 .

[0051] In order to ensure that the fuel and lubricating oil can flow in a predetermined direction and prevent the mixed oil from flowing back to the fuel delivery structure 200 or the lubricating oil delivery structure 300, the present invention sets a one-way valve 500 at the connection between the mixing pipe 410 and the first pipe 430 and the second pipe 440. At the connection between the mixing pipe 410 and the first pipe 430, the present invention sets a first one-way valve 500 to ensure that the fuel can only flow from the first pipe 430 into the mixing pipe 410 and cannot flow in the reverse direction. Similarly, at the connection between the mixing pipe 410 and the second pipe 440, the present invention sets a second one-way valve 500 to ensure that the lubricating oil can only flow from the second pipe 440 into the mixing pipe 410 and cannot flow in the reverse direction.

[0052] By providing the first check valve 500 and the second check valve 500, the present invention effectively controls the flow direction of the fuel and the lubricating oil, and avoids the mixed oil from causing unnecessary interference or damage to the fuel delivery structure 200 and the lubricating oil delivery structure 300. At the same time, this also ensures the purity and stability of the oil in the mixing pipe 410, and improves the overall performance and reliability of the equipment.

[0053] In one embodiment, a filter separator 800 is further provided at the connection between the mixing pipe 410 and the first pipe 430 and the second pipe 440 , and the filter separator 800 is used to filter the oil.

[0054] Fuel and lubricating oil may flow in from different sources through the first pipe 430 and the second pipe 440, and finally be mixed in the mixing pipe 410. However, since various impurities such as solid particles, water or other pollutants may be mixed into the fuel and lubricating oil during the transmission process, it is necessary to filter them before mixing the oil.

[0055] The filter separator 800 is installed at the connection between the mixing pipeline 410, the first pipeline 430 and the second pipeline 440, and its purpose is to filter and separate the oil that is about to enter the mixing pipeline 410. The filter separator 800 is usually equipped with precise filtering elements, such as filter screens, filter elements or membrane separators, which can effectively remove solid particles, moisture and most pollutants in the oil.

[0056] Specifically, when the oil passes through the filter separator 800, the impurities therein are intercepted by the filter element, while the pure oil continues to flow to the mixing pipe 410. In this way, not only the quality of the mixed oil can be ensured, but also the service life of other equipment in the system, such as pumps, valves and nozzles, can be extended.

[0057] In one embodiment, a third flow sensor is provided on the mixing pipe 410. The third flow sensor is installed on the mixing pipe 410 and is used to monitor the flow of the mixed oil in real time. Through the third flow sensor, the user can intuitively understand the flow of the oil in the mixing pipe 410, including key information such as flow size and flow stability. This is of great significance for adjusting the delivery ratio of fuel and lubricating oil, optimizing the output flow, and improving equipment performance.

[0058] The setting of the third flow sensor not only improves the transparency and controllability of equipment operation, but also provides users with more accurate and reliable oil flow data. By combining the data of the first flow sensor 240 and the second flow sensor 340, users can further analyze whether the mixing ratio of fuel and lubricating oil is accurate, so as to take corresponding adjustment measures to ensure the stable operation of the equipment and the effective use of oil.

[0059] In one embodiment, the delivery structure includes a fuel pump 220 and a fuel tank 210, and a first pipe 430 is connected to the fuel tank 210. The fuel pump 220 is used to deliver the fuel in the fuel tank 210 into the first pipe 430. The fuel tank 210 is used to store fuel to ensure that the equipment has sufficient fuel supply when needed. The fuel pump 220 is responsible for delivering the fuel in the fuel tank 210 to the mixing pipe 410 through the first pipe 430. The design of the fuel pump 220 takes into account the physical properties of the fuel, such as viscosity and density, to ensure that the fuel can be delivered stably and continuously.

[0060] Then the delivery structure includes a lubricating oil pump 320 and a lubricating oil tank 310. The first pipeline 430 is connected to the lubricating oil tank 310. The lubricating oil pump 320 is used to deliver the lubricating oil in the lubricating oil tank 310 into the first pipeline 430. The lubricating oil tank 310 is used to store lubricating oil to provide necessary lubrication and protection for the equipment. The lubricating oil pump 320 is responsible for delivering the lubricating oil in the lubricating oil tank 310 to the mixing pipeline 410 through the second pipeline 440 (note here that the original description incorrectly mentioned "first pipeline 430", which should be corrected to "second pipeline 440" according to the context). The design of the lubricating oil pump 320 also takes into account the physical properties of the lubricating oil to ensure that the lubricating oil can be delivered stably and continuously.

[0061] It should be noted that although the fuel and lubricating oil are transported to the mixing pipe 410 through different pipes (the first pipe 430 and the second pipe 440), they are mixed in the mixing pipe 410 to form a required oil mixture. This design ensures the independent transportation of fuel and lubricating oil and realizes their mixing, meeting the equipment's demand for multiple oils.

[0062] In one embodiment, the multi-point fuel supply equipment with oil mixing function also includes an expansion interface, which is detachably matched with the fuel outlet 420. The expansion interface is used for subsequent expansion to facilitate the quick connection of the terminal refueling assembly with the multi-point fuel supply equipment with oil mixing function.

[0063] The design of the expansion interface takes into account the connection requirements of various terminal refueling components, ensuring that they can achieve fast and stable connection with the equipment. Through the expansion interface, users can easily replace or expand the terminal refueling components to meet the oil delivery needs in different scenarios. The design of the expansion interface not only improves the versatility and adaptability of the equipment, but also provides users with a more convenient operation experience. In actual applications, users can select appropriate terminal refueling components according to their needs and connect them to the equipment through the expansion interface. This design not only ensures the stability and reliability of the equipment, but also provides users with more choices and flexibility.

[0064] In one embodiment, a first pressure sensor is disposed on the first pipe 430 , a second pressure sensor is disposed on the second pipe 440 , and a third pressure sensor is disposed on the mixing pipe 410 .

[0065] The first pressure sensor is installed on the first pipeline 430 and is used to monitor the pressure changes during the fuel delivery process in real time. Through the first pressure sensor, the user can understand whether the fuel is subjected to sufficient pressure during the delivery process to ensure that the fuel can be smoothly and stably delivered to the mixing pipeline 410. The second pressure sensor is similar to the first pressure sensor. The second pressure sensor is installed on the second pipeline 440 and is used to monitor the pressure changes during the lubricating oil delivery process in real time. Through the second pressure sensor, the user can understand the pressure state of the lubricating oil during the delivery process to ensure that the lubricating oil can be delivered to the mixing pipeline 410 according to the predetermined pressure and flow rate. The third pressure sensor is installed on the mixing pipeline 410 and is used to monitor the pressure of the mixed oil. Through the third pressure sensor, the user can understand whether the pressure of the mixed oil is stable and whether there are problems such as abnormal pressure fluctuations. This is of great significance for ensuring the stability and safety of the mixed oil.

[0066] In one embodiment, the multi-point fuel supply equipment with oil mixing function further includes a control box 600 and a control box 700. The control box 600 is used to supply power to the control box 700, the fuel pump 220, the lubricating oil pump 320, the first pressure sensor, the second pressure sensor, the third pressure sensor, the first flow sensor 240, the second flow sensor 340, and the third flow sensor. The control box 600 is equipped with an appropriate power management module and protection device to ensure that appropriate voltage and current can be provided to each component under various working conditions.

[0067] The control box 700 is the main interface for the user to interact with the device. It has an integrated controller. The first pressure sensor, the second pressure sensor, the third pressure sensor, the first flow sensor 240, the second flow sensor 340 and the third flow sensor respectively collect pressure signals and flow data signals at corresponding positions, and then feed these pressure signals and flow data signals back to the controller in the control box 700. The controller controls the fuel pump 220, the lubricating oil pump 320 and each solenoid valve to perform corresponding actions according to these pressure signals and flow data signals. For example, when the pressure in a certain pipeline is higher than the preset value, the controller can automatically adjust the fuel pump 220 or the lubricating oil pump 320 to stop rotating to control the pressure; when a certain proportion of flow needs to be output, the controller can adjust the opening of the solenoid valve of the corresponding pipeline to adjust the flow.

[0068] Based on the same inventive concept, the second embodiment of the present application discloses a control method for a multi-point fuel supply device with an oil mixing function based on any embodiment of the first aspect, which comprises the following steps:

[0069] Set the required oil and fuel ratio;

[0070] Set the required total oil and fuel output;

[0071] The controller controls the fuel delivery structure 200 and the lubricating oil delivery structure 300 to output fuel and lubricating oil respectively until the delivered amount of fuel and lubricating oil reaches the set total output amount.

[0072] The control method of the multi-point fuel supply equipment with oil mixing function disclosed in the present application meets the demand for high-precision fuel supply by accurately controlling the output ratio and total amount of fuel oil and lubricating oil. The control method is simple and easy to implement, and is applicable to various occasions requiring accurate oil mixing and output control.

[0073] In one embodiment, the controller controls the fuel delivery structure 200 and the lubricating oil delivery structure 300 to output fuel and lubricating oil respectively until the delivered fuel amount and lubricating oil amount reach the set output amount, including:

[0074] When the third flow sensor detects that the flow rate output from the mixing pipe 410 is equal to the set output total amount; and / or

[0075] When the sum of the flow rate output from the fuel pipeline detected by the first flow sensor 240 and the flow rate output from the lubricating oil pipeline detected by the second flow sensor 340 is equal to the set output total amount;

[0076] The controller controls the fuel delivery structure 200 and the lubricating oil delivery structure 300 to stop outputting.

[0077] When the third flow sensor detects that the flow rate outputted from the mixing pipe 410 reaches the preset set value, that is, the flow rate is equal to the set total output, it indicates that the mixed oil has met the user's needs. At the same time, the system can also monitor the output flow rates of the fuel pipe and the lubricating oil pipe respectively through the first flow sensor 240 and the second flow sensor 340. When the sum of the fuel flow rate detected by the first flow sensor 240 and the lubricating oil flow rate detected by the second flow sensor 340 is equal to the preset set value, it also indicates that the total output oil has met the user's needs.

[0078] When any of the above conditions is met (i.e., the flow rate of the mixing pipe 410 reaches the set value, or the sum of the flow rates of the fuel and lubricating oil pipes reaches the set value), the controller will receive the corresponding signal. The controller will then execute the command to stop output, and send stop signals to the fuel delivery structure 200 and the lubricating oil delivery structure 300 respectively to ensure that both stop outputting oil. After stopping the output, the controller will further confirm the readings of each sensor to ensure that the oil output has indeed stopped and has reached the total amount set by the user. If there is any abnormality or error (such as sensor failure, pipeline blockage, etc.), the controller will trigger the corresponding alarm or error handling mechanism.

[0079] The control method of this embodiment provides double protection by simultaneously monitoring the flow of the mixed pipeline 410 and the separate pipeline, ensuring the accuracy and reliability of the oil output, and can stop the output in time when the set output volume is reached, avoiding the waste of oil and excessive wear of the equipment.

[0080] In one embodiment, pressure thresholds of the first pipeline 430 , the second pipeline 440 , and the mixing pipeline 410 are set;

[0081] The pressure in the first pipeline 430 is greater than or equal to a set threshold; and / or

[0082] The pressure in the second pipe 440 is greater than or equal to a set threshold; and / or

[0083] When the pressure in the mixing pipe 410 is greater than or equal to a set threshold;

[0084] The controller controls the fuel delivery structure 200 and the lubricating oil delivery structure 300 to stop outputting.

[0085] Before starting the device or during operation, the user needs to set the pressure thresholds of the first pipeline 430 (fuel pipeline), the second pipeline 440 (lubricating oil pipeline) and the mixed pipeline 410 according to the actual situation of the device and the characteristics of the oil. These thresholds are used to determine whether the pressure in the pipeline is within a safe range. During operation, the device will continuously detect the pressure value in the pipeline in real time through the pressure sensors installed on each pipeline. These pressure sensors will transmit the detected pressure data to the controller in real time so that the controller can make subsequent judgments and processing.

[0086] When the controller receives the data from the pressure sensor, it will immediately make a pressure judgment. If the pressure in the first pipeline 430 is greater than or equal to the set threshold, or the pressure in the second pipeline 440 is greater than or equal to the set threshold, or the pressure in the mixing pipeline 410 is greater than or equal to the set threshold, the controller will consider that the equipment is in an unsafe state. In this case, the controller will immediately send a stop signal to the fuel delivery structure 200 and the lubricating oil delivery structure 300 to ensure that both stop continuing to output oil, thereby avoiding equipment damage or safety accidents.

[0087] When the controller triggers the command to stop output, it will also trigger the alarm mechanism to remind the user that the device is in an abnormal state. The user can check the specific situation of the device according to the alarm information and take corresponding troubleshooting measures. If the fault cannot be solved immediately, the user can choose to shut down the device and contact professional maintenance personnel for repair.

[0088] Among them, when setting the pressure thresholds of the first pipeline 430, the second pipeline 440 and the mixed pipeline 410, the pressure thresholds of the first pipeline 430, the second pipeline 440 and the mixed pipeline 410 can be set to the same value, or the pressure thresholds of the first pipeline 430, the second pipeline 440 and the mixed pipeline 410 can be set to different values ​​according to different situations.
