Description

Technical Field

[0001] This invention relates to the field of volume measurement technology for parts and components, and in particular to a cyclic system and method for volume measurement. Background Technology

[0002] Since the combustion chamber of the cylinder head component in a car engine is a space composed of an irregular curved surface, its volume is calculated by the amount of liquid injected. Currently, the measured liquid is injected using a digital titrator to measure and display the value. The cleanliness of the measured liquid, including foreign matter, impurities, and air bubbles, directly affects the instrument's pipeline blockage and flow rate, making the secondary recovery and treatment step of the measured liquid extremely important.

[0003] The current method for recovering and processing the measuring solution involves pressing a suction bottle with a finger to create negative pressure, aligning it with the liquid, and then drawing in the measuring solution. The solution is then poured into a funnel-shaped filter bottle with high-precision filter paper, utilizing natural downward filtration. Higher precision filter paper results in longer filtration times. The filtered solution is stored in the bottle for later use. When the bottle is full, it is poured back into the digital titrator's storage bottle for reuse. Furthermore, these recovery and processing steps must be performed separately. Additionally, to further improve the cleanliness of the measuring solution, it needs to undergo secondary filtration, progressively using two different precision filter papers (lower to higher precision) to ensure the solution meets reuse standards. The filtration speed also gradually decreases. Therefore, the current method for recovering and processing the measuring solution is inefficient, has unstable suction, and involves numerous and cumbersome procedures. Summary of the Invention

[0004] Therefore, it is necessary to provide a circulation system and volume measurement method for volume measurement, addressing the problems of low efficiency, unstable suction, and numerous and cumbersome operation procedures in current measurement liquid recovery and treatment methods.

[0005] The technical solution is as follows:

[0006] On the one hand, a cyclic system for volume measurement is provided, comprising:

[0007] A liquid storage device, wherein the liquid storage device is provided with a liquid storage chamber;

[0008] The measuring element is provided with a first liquid inlet and a first liquid outlet, the first liquid inlet being connected to the liquid storage chamber, and the measuring element is used to measure the volume of the measuring liquid being added.

[0009] A filter element, comprising a second inlet and a second outlet, the second outlet being connected to the storage chamber, wherein the filter element is used to filter the measuring liquid; and

[0010] A drive pump is connected to the liquid storage chamber.

[0011] The technical solution will be further explained below:

[0012] In one embodiment, the circulation system for volume measurement further includes a first connecting pipe and a second connecting pipe, one end of the first connecting pipe being connected to the first liquid outlet and one end of the second connecting pipe being connected to the second liquid inlet.

[0013] In one embodiment, the circulation system for volume measurement further includes a cover plate covering the combustion chamber of the cylinder head. The cover plate has a first mounting hole and a second mounting hole communicating with the combustion chamber. One end of the first connecting pipe away from the first liquid outlet extends into the first mounting hole to allow the measuring fluid to be added into the combustion chamber. The other end of the second connecting pipe away from the second liquid inlet passes through the second mounting hole to allow it to extend into the combustion chamber.

[0014] In one embodiment, the cover plate has a first inlet on the side away from the cylinder head. The first inlet is located at the end of the first mounting hole away from the combustion chamber, so as to guide the end of the first connecting pipe away from the first liquid outlet into the first mounting hole.

[0015] In one embodiment, the first inlet portion is configured as an inlet groove, which is connected to one end of the first mounting hole. The inner diameter of the end of the inlet groove near the first mounting hole is the same as the inner diameter of the first mounting hole, and the inner diameter of the inlet groove tends to increase in the direction away from the first mounting hole.

[0016] In one embodiment, the inner diameter of the first mounting hole tends to decrease along the direction close to the combustion chamber, and the inner diameter of the end of the first mounting hole close to the combustion chamber is adapted to the outer diameter of the first connecting pipe.

[0017] In one embodiment, the circulation system for volume measurement further includes a first seal disposed between the cover plate and the cylinder head.

[0018] In one embodiment, the circulation system for volume measurement further includes a suction nozzle connected to the end of the second connecting pipe away from the second liquid inlet, the suction nozzle being used to pass through the second mounting hole and extend into the combustion chamber.

[0019] In one embodiment, the liquid storage device is provided with a third mounting hole, a fourth mounting hole, and a fifth mounting hole communicating with the liquid storage chamber. The circulation system for volume measurement further includes a third connecting pipe, a fourth connecting pipe, and a fifth connecting pipe. One end of the third connecting pipe is connected to the first liquid inlet, and the other end of the third connecting pipe passes through the third mounting hole and extends to the bottom of the liquid storage chamber. One end of the fourth connecting pipe is connected to the second liquid outlet, and the other end of the fourth connecting pipe passes through the fourth mounting hole and extends to the top of the liquid storage chamber. One end of the fifth connecting pipe is connected to the drive pump, and the other end of the fifth connecting pipe passes through the fifth mounting hole and extends to the top of the liquid storage chamber.

[0020] On the other hand, a volume measurement method is provided, applied to the aforementioned cyclic system for volume measurement, comprising:

[0021] Move the first liquid outlet above the combustion chamber to allow the measuring liquid to be added into the combustion chamber;

[0022] The measuring device is activated, and the measuring liquid in the reservoir is injected into the combustion chamber through the measuring device;

[0023] When the combustion chamber is filled with the measuring fluid, the value on the measuring element is read.

[0024] Remove the first liquid outlet from the combustion chamber and insert the second liquid inlet into the combustion chamber;

[0025] The drive pump is started, so that the measuring liquid in the combustion chamber can be drawn into the filter element for filtration, and the filtered measuring liquid can enter the storage chamber for storage.

[0026] When all the measuring liquid in the combustion chamber is drawn out, the drive pump is turned off, and the second liquid outlet is moved out of the combustion chamber.

[0027] The circulation system and volume measurement method for volume measurement in the above embodiments, when it is necessary to measure the volume of the combustion chamber, moves the first liquid outlet to the top of the combustion chamber, so that the liquid storage device, measuring device, and cylinder head can be connected in sequence. Then, the measuring device is activated, and the measuring liquid in the liquid storage device is added to the combustion chamber through the measuring device, so that the measuring device can measure the volume of the measuring liquid added to the combustion chamber. When the combustion chamber is full of the measuring liquid, the value on the measuring device is read to realize the measurement of the volume of the combustion chamber. When it is necessary to recycle the measuring liquid in the combustion chamber, the first liquid outlet is moved out of the combustion chamber, and the second liquid inlet is extended into the combustion chamber, so that the cylinder head, filter, and liquid storage device are connected in sequence. Then, the drive pump is started, so that the drive pump can draw gas from the liquid storage chamber, ensuring that a stable negative pressure is generated in the liquid storage chamber, so that the measuring liquid in the combustion chamber can be drawn into the filter for filtration, and the filtered measuring liquid can enter the liquid storage chamber for storage. When all the measuring fluid in the combustion chamber is drawn out, the drive pump shuts off and the second outlet is moved out of the combustion chamber, thus realizing the recycling of the measuring fluid. Compared with current measuring fluid recycling methods, the liquid storage device in this application has the function of storing the recovered measuring fluid for later use, the filter device has the function of keeping the measuring fluid clean for recycling, and the drive pump can provide a stable power source, realizing the integration of measuring fluid recycling and filtration, which is convenient to operate and improves the working efficiency of the circulation system. In addition, the liquid storage device, measuring device, cylinder head and filter device can be connected in sequence to form a closed-loop circulation management system. After the volume measurement is completed, the measuring solution will be drawn into the filter device, filtered by the filter device and directly stored in the sealed liquid storage chamber, effectively blocking external dust, foreign objects, etc., avoiding the measuring fluid from being contaminated again and affecting the measurement accuracy, thus improving the reliability and measurement accuracy of the circulation system.

Detailed Implementation

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 As shown, in one embodiment, a circulation system 10 for volume measurement is provided, including a liquid storage device 100, a measuring device 200, a filter device 300, and a drive pump 400. The liquid storage device 100 has a liquid storage chamber 110; the measuring device 200 has a first inlet 210 and a first outlet 220, the first inlet 210 communicating with the liquid storage chamber 110, and the measuring device 200 is used to measure the volume of the measuring liquid added; the filter device 300 has a second inlet 310 and a second outlet 320, the second outlet 320 communicating with the liquid storage chamber 110, and the filter device 300 is used to filter the measuring liquid; the drive pump 400 is connected to the liquid storage chamber 110.

[0036] In the above embodiment, the circulation system 10 for volume measurement, when it is necessary to measure the volume of the combustion chamber 710, moves the first liquid outlet 220 above the combustion chamber 710, so that the liquid storage device 100, the measuring device 200, and the cylinder head 700 can be connected in sequence. Then, the measuring device 200 is activated, and the measuring liquid in the liquid storage device 100 is added to the combustion chamber 710 through the measuring device 200, thereby enabling the measuring device 200 to measure the volume of the measuring liquid added to the combustion chamber 710. When the combustion chamber 710 is full of measuring liquid, the value on the measuring device 200 is read, thus realizing the measurement of the volume value of the combustion chamber 710. When it is necessary to recover the measuring fluid in the combustion chamber 710, the first outlet 220 is moved out of the combustion chamber 710, and the second inlet 310 is extended into the combustion chamber 710, so that the cylinder head 700, filter element 300, and liquid storage container 100 are connected in sequence. Then, the drive pump 400 is started, which allows the drive pump 400 to draw gas from the liquid storage chamber 110, ensuring a stable negative pressure in the liquid storage chamber 110. This allows the measuring fluid in the combustion chamber 710 to be drawn into the filter element 300 for filtration, and the filtered measuring fluid can then enter the liquid storage chamber 110 for storage. When all the measuring fluid in the combustion chamber 710 has been drawn out, the drive pump 400 is turned off, and the second outlet 320 is moved out of the combustion chamber 710, realizing the recovery and reuse of the measuring fluid. Compared to current methods for recovering and processing measuring fluids, the liquid storage unit 100 in this application has the function of storing the recovered measuring fluid for later use, and the filter element 300 has the function of keeping the measuring fluid clean for recycling and reuse. Furthermore, the drive pump 400 provides a stable power source, realizing integrated recovery and filtration of the measuring fluid, which is convenient to operate and improves the working efficiency of the circulation system 10. In addition, the liquid storage unit 100, measuring element 200, cylinder head 700, and filter element 300 can be connected sequentially to form a closed-loop circulation management system. After volume measurement, the measuring solution is drawn into the filter element 300, filtered, and then directly stored in the sealed liquid storage chamber 110, effectively blocking external dust, foreign matter, etc., preventing the measuring fluid from being re-contaminated and affecting the measurement accuracy, thus improving the reliability and measurement accuracy of the circulation system 10.

[0037] The liquid storage component 100 can be a liquid storage tank, liquid storage vessel, liquid storage bottle, or other liquid storage structure. The measuring component 200 can be a flow meter, digital titrator, or other measuring structure capable of measuring the volume of the liquid being dispensed. The filter component 300 can be a filter, filter element, or other filtration structure. The drive pump 400 can be a vacuum pump, air pump, or other pump structure.

[0038] In this specific embodiment, the liquid storage device 100 is a large-capacity liquid storage bottle, and the measuring device 200 is a digital titrator. The large-capacity liquid storage bottle can replace the liquid storage bottle of the digital titrator itself. The digital titrator has a built-in driver to drive the measuring liquid in the liquid storage chamber 110 to the first outlet 220. The filter element 300 is a high-precision filter element, and the driving pump 400 is a miniature vacuum pump. In this way, rapid recovery of the measuring liquid and high-precision filtration are integrated, making operation more convenient, shortening the measurement time of the combustion chamber 710 volume of the cylinder head 700, and improving the working efficiency of the circulation system 10.

[0039] The capacity of the large-capacity storage bottle is selected based on three times the volume of the measuring liquid consumed by the tested part in one operation. The top 1 / 3 of the storage chamber 110 is reserved as a vacuum zone. The accuracy grade and flow rate of the filter element are selected based on the highest accuracy grade and flow rate of the filter paper. All filtration actions are completed directly during the liquid aspiration process. At the same time, the purity of the measuring liquid after one filtration meets the standard for reuse.

[0040] The part being measured can be a cylinder head 700, a bottle, a box, a can, or other containers whose volume is not convenient to measure directly. This application uses a cylinder head 700 as an example of the part being measured, and should not be construed as a limitation of this application.

[0041] like Figure 1 As shown, the circulation system 10 for volume measurement further includes a first connecting pipe 510 and a second connecting pipe 520. One end of the first connecting pipe 510 is connected to the first liquid outlet 220, and one end of the second connecting pipe 520 is connected to the second liquid inlet 310. Thus, by moving the end of the first connecting pipe 510 away from the first liquid outlet 220 to above the combustion chamber 710, the first liquid storage port 220 can be connected to the combustion chamber 710 through the first connecting pipe 510. Furthermore, by extending the end of the second connecting pipe 520 away from the second liquid inlet 310 into the combustion chamber 710, the combustion chamber 710 can be connected to the second liquid inlet 310 through the second connecting pipe 520. This improves the convenience and practicality of the circulation system 10.

[0042] In this embodiment, both the first connecting pipe 510 and the second connecting pipe 520 are flexible hoses with small orifice diameters that are resistant to bending. This improves the practicality and service life of the circulation system 10.

[0043] like Figure 1Optionally, the circulation system 10 for volume measurement further includes a cover plate 600, which covers the combustion chamber 710 of the cylinder head 700. The cover plate 600 has a first mounting hole 610 and a second mounting hole 620 communicating with the combustion chamber 710. One end of the first connecting pipe 510 away from the first liquid outlet 220 extends into the first mounting hole 610 to allow the addition of measuring fluid into the combustion chamber 710. The other end of the second connecting pipe 520 away from the second liquid inlet 310 passes through the second mounting hole 620 to allow it to extend into the combustion chamber 710. In this way, the cover plate 600 can prevent external dust and other foreign objects from entering the combustion chamber 710 and contaminating the measuring fluid in the combustion chamber 710, thereby increasing the cleanliness of the measuring fluid in the combustion chamber 710 and improving the measurement accuracy of the circulation system 10.

[0044] The cover plate 600 can be a transparent plate. Specifically, the cover plate 600 can be a glass plate or a transparent plastic plate, etc. This makes it convenient for the measuring personnel to observe the condition of the measuring fluid inside the combustion chamber 710.

[0045] like Figure 1 As shown, in one embodiment, a first inlet portion 630 is provided on the side of the cover plate 600 away from the cylinder head 700. The first inlet portion 630 is located at the end of the first mounting hole 610 away from the combustion chamber 710, so that the end of the first connecting pipe 510 away from the first liquid outlet 220 can be guided into the first mounting hole 610. In this way, the first connecting pipe 510 can move smoothly and quickly above the combustion chamber 710 under the guidance of the first inlet portion 630, improving the convenience of the circulation system 10.

[0046] The first inlet section 630 can be an inlet block, an inlet tube, an inlet groove, or other inlet structures.

[0047] like Figure 1 As shown, further, a second inlet 640 is provided on the side of the cover plate 600 away from the cylinder head 700. The second inlet 640 is located at the end of the second mounting hole 620 away from the combustion chamber 710, so that the end of the second connecting pipe 520 away from the second liquid inlet 310 can be guided into the second mounting hole 620. In this way, the second connecting pipe 520 can move smoothly and quickly above the combustion chamber 710 under the guidance of the second inlet 640, improving the convenience of the circulation system 10.

[0048] The second inlet 640 can be an inlet block, an inlet tube, an inlet groove, or other inlet structures.

[0049] To facilitate understanding of the working principle of the circulation system 10, this application uses the example of the first mounting hole 610 and the second mounting hole 620 having the same shape and structure, the first inlet portion 630 and the second inlet portion 640 having the same shape and structure, and the first connecting pipe 510 and the second connecting pipe 520 having the same shape and structure for detailed explanation. In other embodiments, the shape and structure of the first mounting hole 610 and the second mounting hole 620 may be different, the shape and structure of the first inlet portion 630 and the second inlet portion 640 may be different, and the shape and structure of the first connecting pipe 510 and the second connecting pipe 520 may be different.

[0050] Optionally, the first inlet portion 630 is configured as an inlet groove, which communicates with one end of the first mounting hole 610. The inner diameter of the end of the inlet groove near the first mounting hole 610 is the same as the inner diameter of the first mounting hole 610, and the inner diameter of the inlet groove tends to increase in the direction away from the first mounting hole 610. In this way, the first connecting pipe 510 first extends into the inlet groove with the larger inner diameter, so that the inner sidewall of the inlet groove can guide the first connecting pipe 510, ensuring that the first connecting pipe 510 can pass through the first mounting hole 610 smoothly and quickly, thereby improving the working efficiency of the circulation system 10. Specifically, in this embodiment, the chamfer of the inlet groove is 45°.

[0051] The inner diameter of the guide groove tends to increase in the direction away from the first mounting hole 610. This can be a linear increase in the inner diameter of the guide groove in the direction away from the first mounting hole 610, for example, the inner wall of the guide groove is a plane. Alternatively, the inner diameter of the guide groove can increase non-linearly in the direction away from the first mounting hole 610, for example, the inner wall of the guide groove is an arc surface.

[0052] In one embodiment, the inner diameter of the first mounting hole 610 tends to decrease towards the combustion chamber 710, and the inner diameter of the end of the first mounting hole 610 near the combustion chamber 710 is adapted to the outer diameter of the first connecting pipe 510. Thus, when the first connecting pipe 510 extends into the first mounting hole 610, due to the guiding and sealing effect of the inner wall of the first mounting hole 610, the first connecting pipe 510 is quickly and accurately installed above the combustion chamber 710. This allows for the addition of measuring fluid to the combustion chamber 710 while the inner wall of the first mounting hole 610 seals against the outer wall of the first connecting pipe 510, preventing external dust and other foreign matter from entering the combustion chamber 710 through the first mounting hole 610. This ensures the measuring fluid inside the combustion chamber 710 remains clean, improving the measurement accuracy and convenience of the circulation system 10. Specifically, in this embodiment, the first mounting hole 610 has a certain guiding taper. When it is necessary to add measuring fluid to the combustion chamber 710, the inner wall of the first mounting hole 610 is sealed to the outer wall of the first connecting pipe 510, and the second mounting hole 620 is in the open state so that the gas in the combustion chamber 710 can be discharged.

[0053] Optionally, the circulation system 10 for volume measurement also includes a first seal (not shown), which is disposed between the cover plate 600 and the cylinder head 700. In this way, the first seal can prevent external dust and other foreign matter from entering the combustion chamber 710 through the gap between the cover plate 600 and the cylinder head 700, thereby contaminating the measuring fluid in the combustion chamber 710, increasing the cleanliness of the measuring fluid in the combustion chamber 710, and improving the measurement accuracy of the circulation system 10.

[0054] The first sealing element can be a sealing ring, sealing ring, sealing gasket, or other sealing structure. Specifically, in this embodiment, the first sealing element can be a sealing film layer. For example, after uniformly applying silicone oil or medical petroleum jelly to the side of the cover plate 600 near the cylinder head 700, the cover plate 600 is placed on the cylinder head 700 and pressed down with a certain weight pressure to finally form a sealing film layer. Thus, the sealing condition between the cover plate 600 and the cylinder head 700 can be judged by observing bubbles in the film layer on the surface of the cover plate 600. The absence of bubbles indicates a complete seal, preventing leakage when the measuring fluid is injected into the combustion chamber 710.

[0055] In other embodiments, the circulation system 10 for volume measurement further includes a second seal (not shown), which is disposed within the first mounting hole 610 to seal the inner wall of the first mounting hole 610 with the outer wall of the first connecting pipe 510. Thus, the second seal prevents external dust and other foreign matter from entering the combustion chamber 710 through the first mounting hole 610, thereby contaminating the measuring fluid within the combustion chamber 710 and increasing the cleanliness of the measuring fluid, thus improving the measurement accuracy of the circulation system 10.

[0056] Optionally, the circulation system 10 for volume measurement also includes a third seal (not shown), which is disposed within the second mounting hole 620 to seal the inner wall of the second mounting hole 620 with the outer wall of the second connecting pipe 520. In this way, the third seal prevents external dust and other foreign matter from entering the combustion chamber 710 through the second mounting hole 620, thus preventing contamination of the measuring fluid within the combustion chamber 710. This increases the cleanliness of the measuring fluid within the combustion chamber 710 and improves the measurement accuracy of the circulation system 10.

[0057] The second and third sealing elements can be sealing rings, sealing sleeves, or other sealing structures.

[0058] In one embodiment, the circulation system 10 for volume measurement further includes a suction nozzle (not shown), which is connected to the end of the second connecting pipe 520 away from the second liquid inlet 310. The suction nozzle is used to pass through the second mounting hole 620 and extend into the combustion chamber 710. In this way, the measuring liquid in the combustion chamber 710 can sequentially pass through the suction nozzle and the second connecting pipe 520 into the filter element 300 for filtration, improving the convenience of the circulation system 10.

[0059] Specifically, in this embodiment, the suction nozzle is set as a fine suction nozzle, and the outer diameter of the fine suction nozzle is selected according to the inner diameter of the second mounting hole 620 of the cover plate 600. That is, the fine suction nozzle can be inserted into the combustion chamber 710 through the second mounting hole 620 to suck up liquid.

[0060] Optionally, the circulation system 10 for volume measurement also includes an adapter (not shown) for connecting the suction nozzle to the end of the second connecting tube 520 away from the second inlet 310. This improves the convenience of the circulation system 10. Specifically, in this embodiment, the adapter is a double-port large-to-small conversion adapter.

[0061] like Figure 1 As shown, in one embodiment, the liquid storage component 100 is provided with a third mounting hole, a fourth mounting hole, and a fifth mounting hole communicating with the liquid storage chamber 110. The circulation system 10 for volume measurement also includes a third connecting pipe 530, a fourth connecting pipe 540, and a fifth connecting pipe 550. One end of the third connecting pipe 530 is connected to the first liquid inlet 210, and the other end of the third connecting pipe 530 passes through the third mounting hole and extends to the bottom of the liquid storage chamber 110. One end of the fourth connecting pipe 540 is connected to the second liquid outlet 320, and the other end of the fourth connecting pipe 540 passes through the fourth mounting hole and extends to the top of the liquid storage chamber 110. One end of the fifth connecting pipe 550 is connected to the drive pump 400, and the other end of the fifth connecting pipe 550 passes through the fifth mounting hole and extends to the top of the liquid storage chamber 110. In this way, the relative positions of the measuring component 200, the filter component 300, and the drive pump 400 can be flexibly adjusted according to the actual needs of use, improving the convenience and applicability of the circulation system 10.

[0062] Specifically, in this embodiment, the third connecting pipe 530, the fourth connecting pipe 540, and the fifth connecting pipe 550 are all flexible, small-diameter tubes that are resistant to bending. The third mounting hole, the fourth mounting hole, and the fifth mounting hole are all located on the top of the liquid storage component 100.

[0063] Optionally, the outer wall of the third connecting pipe 530 is sealed to the inner wall of the third mounting hole, the outer wall of the fourth connecting pipe 540 is sealed to the inner wall of the fourth mounting hole, and the outer wall of the fifth connecting pipe 550 is sealed to the inner wall of the fifth mounting hole. This ensures a sealed environment within the liquid storage chamber 110, preventing external dust and other foreign matter from contaminating the measuring liquid and improving the measurement accuracy of the circulation system 10.

[0064] like Figure 2 As shown, in one embodiment, a volume measurement method is provided, applied to the cyclic system 10 for volume measurement in any of the above embodiments, comprising at least the following steps:

[0065] S100: Move the first liquid outlet 220 above the combustion chamber 710 to allow the measuring fluid to be added into the combustion chamber 710. Specifically, in this embodiment, the first liquid outlet 220 is moved to a position flush with the bottom surface of the cover plate 600. This facilitates the addition of the measuring fluid from the liquid storage chamber 110 into the combustion chamber 710.

[0066] S200: The measuring element 200 is activated, and the measuring fluid in the reservoir 100 is injected into the combustion chamber 710 through the measuring element 200. In this way, the measuring element 200 can measure the volume of the measuring fluid injected into the combustion chamber 710 in real time, so as to measure the volume of the combustion chamber 710, which is composed of an irregular curved surface.

[0067] S300: When the combustion chamber 710 is filled with measuring fluid, the value on the measuring element 200 is read. In this way, by using the fact that the volume of the measuring fluid added to the combustion chamber 710 is the same as the volume of the combustion chamber 710, the volume value of the combustion chamber 710 is measured.

[0068] S400: Move the first liquid outlet 220 out of the combustion chamber 710 and extend the second liquid inlet 310 into the combustion chamber 710. In this way, the cylinder head 700, filter element 300 and liquid storage element 100 are connected in sequence to facilitate the recycling of the measuring liquid.

[0069] S500 and the drive pump 400 start, allowing the measuring liquid in the combustion chamber 710 to be drawn into the filter element 300 for filtration. The filtered measuring liquid then enters the storage chamber 110 for storage. In this way, the drive pump 400 can extract gas from the storage chamber 110, creating a stable negative pressure within it. This allows the measuring liquid in the combustion chamber 710 to be drawn into the filter element 300 for filtration, and the filtered liquid to enter the storage chamber 110 for storage, achieving the recycling of the measuring liquid. Furthermore, after filtration by the filter element 300, the liquid is directly stored in the sealed storage chamber 110, effectively blocking external dust and foreign matter, preventing recontamination of the measuring liquid and ensuring measurement accuracy, thus improving the reliability and accuracy of the circulation system 10.

[0070] S600: When all the measuring fluid in the combustion chamber 710 is drawn out, the drive pump 400 is turned off, and the second outlet 320 is moved out of the combustion chamber 710. In this way, the measuring fluid can flow back into the storage chamber 110 to facilitate volume measurement of the next part being measured.

[0071] The circulation system 10 and volume measurement method used for volume measurement feature rapid recovery, automatic filtration, and convenient operation. Furthermore, after actual measurement and verification of the circulation system 10 for volume measurement, it was found to have at least the following advantages: 1. Low investment: the design and implementation of the system are independent, with a production cost of only 560 yuan. 2. Simplified operation: the liquid aspiration and filtration are fully automated and integrated, making operation simple and quick. 3. Increased efficiency: the volume measurement time is reduced to the preset target time, improving work efficiency. 4. Reduced workload: manual liquid aspiration is eliminated, reducing the labor intensity of measurement personnel. 5. Significant benefits: 7684 minutes of working time are saved annually, resulting in savings of 21770 yuan / year in overtime costs, 1500 yuan / year in filter paper consumption, and 200 yuan / year in filter cartridges, totaling savings of 23070 yuan / year.

[0072] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0073] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0074] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0075] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0076] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0077] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
