[0002] At present, in the use process of some marine diesel engines, the water temperature deviation of two sides of the water outlet in the front flow channel of the water pump water inlet pipe of the cooling system is high. It is found through analysis that when the large and small circulation water quantities are equal, the large circulation low-temperature cooling water almost flows to the water outlet on the side close to the large circulation low-temperature cooling water inlet, and the small circulation high-temperature cooling water almost flows to the water outlet on the other side, thereby causing the problem of large water temperature deviation of the two sides of the water outlet in the front flow channel of the water pump water inlet pipe, and further affecting the cooling effect of the diesel engine. SUMMARY

[0003] Embodiments of the present application provide a method and equipment for adjusting the water temperature of a water pump water inlet pipe assembly, to solve the problem of large water temperature deviation of the two sides of the water outlet in the front flow channel of the water pump water inlet pipe.

[0004] In a first aspect, embodiments of the present application provide a method for adjusting the water temperature of a water pump water inlet pipe assembly, the water pump water inlet pipe assembly comprising a first flow guide fin arranged on a first side plate and a second flow guide fin arranged on a second side plate opposite to the first side plate at a confluence, a projection of the first flow guide fin on the plane of the first side plate and a projection of the second flow guide fin on the plane of the first side plate being arranged in a cross manner, and a temperature sensor being arranged in each of a first water outlet pipe and a second water outlet pipe of the water pump water inlet pipe assembly, the method comprising:

[0005] determining a first temperature of the first water outlet pipe and a second temperature of the second water outlet pipe;

[0006] determining a first temperature difference between the first temperature and the second temperature;

[0007] when the first temperature difference does not satisfy a set condition, adjusting the height of the first flow guide fin and the second flow guide fin in the confluence.

[0008] Based on the above scheme, the first flow guide fin is arranged on the first side plate and the second flow guide fin is arranged on the second side plate at the confluence of the water pump water inlet pipe assembly, so as to change the water flow direction. When the temperature difference is adjusted, the difference between the water temperatures in the two water outlet pipes can be detected, and then the height of the flow guide fin relative to the side plate in the confluence is adjusted according to the difference between the water temperatures, so as to make the temperature difference between the two water outlet pipes after adjustment meet the requirements.

[0009] In a possible implementation manner, the adjusting the height of the first flow guide fin and the second flow guide fin in the confluence comprises:

[0010] When the first temperature is less than the second temperature, repeatedly performing the following operations: lowering the height of the first guide fin and the second guide fin in the confluence part by a set height respectively, and obtaining a new first temperature and a new second temperature after a first set time interval; until the temperature difference between the new first temperature and the new second temperature meets the set condition;

[0011] When the first temperature is greater than the second temperature, repeatedly performing the following operations: increasing the height of the first guide fin and the second guide fin in the confluence part by a set height respectively, and obtaining a new first temperature and a new second temperature after a first set time interval; until the temperature difference between the new first temperature and the new second temperature meets the set condition.

[0016] Based on the above scheme, when it is determined that the temperature difference meets the set condition, the new temperature difference can be determined by again obtaining the temperatures of the two water outlet pipes, and then the height of the first guide fin and the second guide fin can be adjusted again when the new temperature difference does not meet the condition.

[0019] Determining a new temperature difference according to the first temperature and the second temperature obtained at the same set time interval, so that when the new temperature difference does not meet the set condition, the height of the first guide fin and the second guide fin in the confluence part is adjusted respectively.

[0020] Based on the above scheme, when the temperature difference meets the set condition but the temperature difference changes greatly between two adjacent times, the temperature difference is obtained at a set time interval, so that the water inflow of the two water inflow pipes is different, and the water temperature of the two water outflow pipes can be adjusted in time to meet the requirements.

[0021] In a possible implementation, the set condition is that the absolute value of the temperature difference is less than a second set value.

[0022] In a possible implementation, the extension direction of the first flow guide rib is consistent with the water flow direction in the first water inflow pipe, and the extension direction of the second flow guide rib is consistent with the water flow direction in the second water inflow pipe.

[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus including a series of elements includes not only those elements, but also other elements not explicitly listed, or other elements inherent in such a process, method, article or apparatus. Without more limitations, the element defined by the statement "comprising a" does not exclude the presence of additional identical elements in the process, method, article or apparatus including the element.

[0043] At present, some marine diesel engines have the problem of high water temperature deviation of the two outlets in the flow channel before the water inlet pipe of the cooling system during use. Through analysis, it is found that when the large and small circulation water quantities are equal, the large circulation low-temperature cooling water almost flows to the outlet on the side close to the large circulation low-temperature cooling water inlet, and the small circulation high-temperature cooling water almost flows to the outlet on the other side, thereby causing the problem of large water temperature deviation of the two outlets in the flow channel before the water inlet pipe, and further affecting the cooling effect of the diesel engine.

[0044] Based on the above problem, the embodiments of the application provide a method and equipment for adjusting the outlet water temperature of a water pump water inlet pipe assembly, which are applied to a cooling system including a water pump water inlet pipe assembly. The water pump water inlet pipe assembly includes a first guide vane arranged on a first side plate and a second guide vane arranged on a second side plate opposite to the first side plate at a confluence part, the projection of the first guide vane on the plane of the first side plate and the projection of the second guide vane on the plane of the first side plate are cross arranged, and temperature sensors are arranged in the first outlet pipe and the second outlet pipe of the water pump water inlet pipe assembly respectively. By obtaining the water temperatures of the two outlet pipes, the height of the guide vane in the confluence part is adjusted according to the temperature difference of the two outlet pipes, so that the temperature difference of the two outlet pipes meets the set requirement.

[0045] Next, the structure of the water pump water inlet pipe assembly related to the embodiments of the application is described.

[0046] Reference Figures 1 to 5The water pump water inlet pipe assembly in the embodiment of the application can include a first water inlet pipe 100, a second water inlet pipe 200, a merging portion 300, a first water outlet pipe 400, a second water outlet pipe 500, a first flow guide rib 600, and a second flow guide rib 700. The merging portion 300 includes a first side plate 310, a second side plate 320, and a connecting plate 330. The first side plate 310 and the second side plate 320 are oppositely arranged, and the connecting plate 330 is connected between the first side plate 310 and the second side plate 320, so that the first side plate 310, the second side plate 320, and the connecting plate 330 surround to form an accommodation space. The first water inlet pipe 100, the second water inlet pipe 200, the first water outlet pipe 400, and the second water outlet pipe 500 are all connected to the connecting plate 330 and communicate with the accommodation space. That is, the water flow flowing into the first water inlet pipe 100 and the second water inlet pipe 200 flows to the first water outlet pipe 400 and the second water outlet pipe 500 through the merging portion 300.

[0047] As shown in Figure 1 , the water pump water inlet pipe assembly in the embodiment of the application is applied to a water pipe in front of a pump. In order to facilitate the connection of the first water outlet pipe 400 and the second water outlet pipe 500 with the water pump, the first water inlet pipe 100 and the second water inlet pipe 200 can be located on the side away from the water pump, and the first water outlet pipe 400 and the second water outlet pipe 500 can be located on the side close to the water pump. In other words, the first water inlet pipe 100 and the second water inlet pipe 200 in the embodiment are designed in a non-diagonal line position, and the first water outlet pipe 400 and the second water outlet pipe 500 are also designed in a non-diagonal line position. In addition, the first water inlet pipe 100 and the second water outlet pipe 500 can be roughly designed as a diagonal line, and the second water inlet pipe 200 and the first water outlet pipe 400 can be roughly designed as a diagonal line.

[0048] In some embodiments, the first flow guide rib 600 in the embodiment can be one first flow guide rib, or two or more first flow guide ribs, and the second flow guide rib 700 can be one second flow guide rib, or two or more second flow guide ribs. The specific number of flow guide ribs is not limited in the application. Specifically, in combination with Figure 2 、 Figure 4 and Figure 5 , the first flow guide rib 600 is arranged on the first side plate 310, at least a part of the first flow guide rib 600 protrudes from the first side plate 310 toward the side surface of the second side plate 320, the second flow guide rib 700 is arranged on the second side plate 320, and at least a part of the second flow guide rib 700 protrudes from the second side plate 320 toward the side surface of the first side plate 310.

[0049] In some embodiments, the projection of the first guide fin on the plane of the first side plate and the projection of the second guide fin on the plane of the first side plate are arranged in a cross manner. Since the first side plate and the second side plate are arranged oppositely, it can also be understood that the projection of the first guide fin on the plane of the first side plate and the projection of the second guide fin on the plane of the first side plate are arranged in a cross manner. Figure 1 Or Figure 3 The extension direction of the orthographic projection of the first guide fin 600 on the first side plate and the extension direction of the orthographic projection of the second guide fin 700 on the first side plate are arranged in a cross manner, so that the water flow entering the converging portion 300 from the first water inlet pipe 100 flows to the first water outlet pipe 400 and the second water outlet pipe 500 under the cooperation of the first guide fin 600 and the second guide fin 700, and the water flow entering the converging portion 300 from the second water inlet pipe 200 also flows to the first water outlet pipe 400 and the second water outlet pipe 500 under the cooperation of the first guide fin 600 and the second guide fin 700.

[0050] It should be understood that the water pump water inlet pipe assembly in the embodiment can be applied to the cooling system of an engine. When the water inlet temperatures of the first water inlet pipe 100 and the second water inlet pipe 200 are different, assuming that the first water inlet pipe 100 contains high-temperature water and the second water inlet pipe 200 contains low-temperature water, without the first guide fin 600 and the second guide fin 700, the water in the first water inlet pipe 100 flows to the first water outlet pipe 400, and the water in the second water inlet pipe 200 flows to the second water outlet pipe 500, thereby causing the water outlet temperature of the first water outlet pipe 400 to be high and the water outlet temperature of the second water outlet pipe 500 to be low. With the first guide fin 600 and the second guide fin 700, part of the high-temperature water in the first water inlet pipe 100 flows to the second water outlet pipe 500, and part of the low-temperature water in the second water inlet pipe 200 flows to the first water outlet pipe 400, so that the first water outlet pipe 400 and the second water outlet pipe 500 respectively have high-temperature water and low-temperature water mixed with each other, thereby reducing the water outlet temperature difference between the first water outlet pipe 400 and the second water outlet pipe 500, and making the water outlet temperatures of the first water outlet pipe 400 and the second water outlet pipe 500 substantially consistent.

[0051] As mentioned above, the first and second flow guides 600 and 700 can be one, two, three, etc. When the first flow guide 600 is one, it can be located at the center of the first side plate 310, and when the second flow guide 700 is one, it can also be located at the center of the second side plate 320. When the first flow guide 600 is two, the two first flow guides 600 can be symmetrically arranged with the center line of the first side plate 310 as the axis of symmetry, and when the second flow guide 700 is two, the two second flow guides 700 can be symmetrically arranged with the center line of the second side plate 320 as the axis of symmetry. In addition, when the first flow guide 600 is two or more, each first flow guide 600 is parallel to the adjacent first flow guide 600. When the second flow guide 700 is two or more, each second flow guide 700 is parallel to the adjacent second flow guide 700.

[0052] In combination Figure 1 and Figure 3 Taking the first and second flow guides 600 and 700 as two examples, the extension direction of the first flow guide 600 is consistent with the water flow direction in the first water inlet pipe 100, and the extension direction of the second flow guide 700 is consistent with the water flow direction in the second water inlet pipe 200. The two first flow guides 600 form a channel a extending in the same direction as the first flow guide 600, which can be used to guide the water in the first water inlet pipe 100 to the second water outlet pipe 500, and the two second flow guides 700 form a channel b extending in the same direction as the second flow guide 700, which can be used to guide the water in the second water inlet pipe 200 to the first water outlet pipe 400, thereby increasing the mixed water flow in the first and second water outlet pipes 400 and 500 and reducing the water temperature difference between the first and second water outlet pipes 400 and 500.

[0053] In this embodiment, the amount of water diverted in the first and second water inlet pipes 100 and 200 can be adjusted by adjusting the height of the channels a and b. It can be understood that when the height of the channel a is higher, more water in the first water inlet pipe 100 can enter the second water outlet pipe 500 through the channel a, and when the height of the channel b is higher, more water in the second water inlet pipe 200 can enter the first water outlet pipe 400 through the channel b.

[0054] Specifically, as an optional embodiment, as Figure 2 and Figure 4As shown, the first side plate 310 can be provided with a first fixing slot 311 corresponding to each first flow guide rib 600, each first flow guide rib 600 is installed in the corresponding first fixing slot 311, and at least a part of the first flow guide rib 600 protrudes from the side surface of the first side plate 310 away from the second side plate 320. The second side plate 320 can be provided with a second fixing slot 321 corresponding to each second flow guide rib 700, each second flow guide rib 700 is installed in the corresponding second fixing slot 321, and at least a part of the second flow guide rib 700 protrudes from the side surface of the second side plate 320 away from the first side plate 310.

[0055] The first flow guide rib 600 can move relative to the first fixing slot 311 along the arrangement direction of the first side plate 310 and the second side plate 320 to change the height of the first flow guide rib 600 protruding from the first side plate 310 toward the side surface of the second side plate 320, so as to change the volume of the channel a, and further change the temperature of the mixed water in the first water outlet pipe 400 and the second water outlet pipe 500. Similarly, the second flow guide rib 700 can move relative to the second fixing slot 321 along the arrangement direction of the first side plate 310 and the second side plate 320 to change the height of the second flow guide rib 700 protruding from the second side plate 320 toward the side surface of the first side plate 310, so as to change the volume of the channel b, and further change the temperature of the mixed water in the first water outlet pipe 400 and the second water outlet pipe 500.

[0056] When adjusting the relative position between the first flow guide rib 600 and the first fixing slot 311, it can be achieved by contacting the part of the first flow guide rib 600 outside the confluence part 300 (i.e. the part of the first flow guide rib 600 protruding from the side surface of the first side plate 310 away from the second side plate 320), for example, it can be manually adjusted or driven by using a driving device. Similarly, when adjusting the relative position between the second flow guide rib 700 and the first fixing slot 311, it can be achieved by contacting the part of the second flow guide rib 700 protruding from the side surface of the second side plate 320 away from the first side plate 310.

[0057] In addition, the first guide ribs 600 are in interference fit with the first fixing grooves 311, and the second guide ribs 700 are in interference fit with the second fixing grooves 321. It should be noted that, taking the first guide ribs 600 and the first fixing grooves 311 as an example, the interference fit between the first guide ribs 600 and the first fixing grooves 311 can be understood as follows: when a part of the first guide ribs 600 is located in the first fixing grooves 311, the first guide ribs 600 and the first fixing grooves 311 can be kept relatively fixed without external force driving the first guide ribs 600 along the arrangement direction of the first side plate 310 and the second side plate 320, and the first guide ribs 600 can move relative to the first fixing grooves 311 when intervened by external force. In this way, the height of the first guide ribs 600 or the second guide ribs 700 can be kept fixed after the height adjustment is completed, so as to ensure the stability of the water temperature of the first water outlet pipe 400 and the second water outlet pipe 500.

[0058] As an optional embodiment, the water pump water inlet pipe assembly in the embodiment further includes a first driving device (not shown in the figure) and a second driving device (not shown in the figure), the first driving device is used to drive the first guide ribs 600 to move synchronously along the arrangement direction of the first side plate 310 and the second side plate 320, and the second driving device is used to drive the second guide ribs 700 to move synchronously along the arrangement direction of the first side plate 310 and the second side plate 320. In this way, the heights of the first guide ribs 600 protruding from the first side plate 310 towards one side surface of the second side plate 320 can be the same, and the heights of the second guide ribs 700 protruding from the second side plate 320 towards one side surface of the first side plate 310 can be the same.

[0059] Further, the water pump water inlet pipe assembly in the embodiment can further include temperature sensors respectively arranged in the first water outlet pipe 400 and the second water outlet pipe 500, and each temperature sensor can be used to detect the water temperature in the first water outlet pipe 400 and the second water outlet pipe 500. On this basis, a control unit can be further arranged, and a control strategy can be formulated, for example, the control unit can control the first driving device and the second driving device to work according to the temperature in the first water outlet pipe 400 and the second water outlet pipe 500, so as to adjust the height of the first guide ribs 600 and the second guide ribs 700 in the confluence part 300, so that the water temperature when flowing out of the first water outlet pipe 400 and the second water outlet pipe 500 is consistent when the water flow and the temperature in the first water inlet pipe 100 and the second water inlet pipe 200 are different.

[0060] In the embodiment, the interval between the first side plate 310 and the second side plate 320 is H, when adjusting the height H1 of the first flow guide rib 600 protruding from the first side plate 310 to the side surface of the second side plate 320, H1 needs to satisfy: 0 < H1 < 0.5H. When adjusting the height H2 of the second flow guide rib 700 protruding from the second side plate 320 to the side surface of the first side plate 310, H2 needs to satisfy: 0 < H2 < 0.5H. Through the above design, on the one hand, the interference between the first flow guide rib 600 and the second flow guide rib 700 can be avoided when the protruding height of the first flow guide rib 600 or the second flow guide rib 700 is too high, on the other hand, the influence of the pressure drop caused by the protruding height of the first flow guide rib 600 or the second flow guide rib 700 being too high can also be avoided.

[0061] The embodiment of the present application provides a method for adjusting the outlet water temperature of a water pump inlet pipe assembly. Referring to FIG. 6, the specific process of the method is as follows: Figure 6

[0062] 601, determining a first temperature of a first outlet pipe and a second temperature of a second outlet pipe.

[0063] In the embodiment of the present application, the first outlet pipe is the outlet pipe on the same side of the high-temperature inlet pipe and approximately diagonal to the low-temperature inlet pipe, and the second outlet pipe is the outlet pipe on the same side of the low-temperature inlet pipe and approximately diagonal to the high-temperature inlet pipe. The first temperature T1 of the first outlet pipe and the second temperature T2 of the second outlet pipe can be determined by a temperature sensor.

[0064] 602, determining a first temperature difference between the first temperature and the second temperature.

[0065] In some embodiments, the first temperature difference is the absolute value of the temperature difference between the first temperature and the second temperature. Then, according to the above example, the first temperature difference can be represented as |T1-T2|.

[0066] 603, when the first temperature difference does not satisfy a set condition, adjusting the height of the first flow guide rib and the second flow guide rib in the convergence part, respectively.

[0067] The set condition can be that the absolute value of the temperature difference is less than a second set value. For example, the water temperature in the first outlet pipe, i.e., the first temperature, is T1, and the water temperature in the second outlet pipe, i.e., the first temperature, is T2, and the set condition can be |T1-T2|<1.

[0068] In some embodiments, when the first temperature is less than the second temperature, the following operations are repeatedly performed: respectively lowering the height of the first flow guide rib and the second flow guide rib in the convergence part by a set height. And, after a first set time interval, new first temperature and new second temperature are obtained, until the temperature difference between the new first temperature and the new second temperature satisfies the set condition.

[0069] ​Next, the above example is taken as an example, the first water inlet pipe is a high-temperature water inlet pipe, and the second water inlet pipe is a low-temperature water inlet pipe. When the first temperature in the first water outlet pipe is less than the second temperature in the second water outlet pipe, that is, T1 < T2, it indicates that the height of the first guide fin and the second guide fin in the merging portion is too high, resulting in that more high-temperature water in the high-temperature water inlet pipe enters the channel a, and more low-temperature water in the low-temperature water inlet pipe enters the channel b. Therefore, the height of the first guide fin and the second guide fin in the merging portion can be reduced to a set height. In some scenarios, the height of the first guide fin and the second guide fin in the merging portion can be adjusted by a driving device in the cooling system. Further, when T1 < T2, the height of the first guide fin and the second guide fin can be reduced by (T2-T1) millimeters.

[0070] In some scenarios, after the height of the first guide fin and the second guide fin is reduced, new first and second temperatures can be obtained after a set time interval. The set time interval can be set to 3 minutes to avoid unstable water temperature caused by unstable water flow after the height of the guide fin is adjusted.

[0071] When the first temperature is greater than the second temperature, the following operations are repeatedly performed: the height of the first guide fin and the second guide fin in the merging portion is increased by a set height, respectively, and new first and second temperatures are obtained after a first set time interval; and the temperature difference between the new first and second temperatures satisfies a set condition.

[0072] Next, the above example is taken as an example, the first water inlet pipe is a high-temperature water inlet pipe, and the second water inlet pipe is a low-temperature water inlet pipe. When the first temperature in the first water outlet pipe is less than the second temperature in the second water outlet pipe, that is, T1 < T2, it indicates that the height of the first guide fin and the second guide fin in the merging portion is too high, resulting in that more high-temperature water in the high-temperature water inlet pipe enters the channel a, and more low-temperature water in the low-temperature water inlet pipe enters the channel b. Therefore, the height of the first guide fin and the second guide fin in the merging portion can be reduced to a set height. In some scenarios, the height of the first guide fin and the second guide fin in the merging portion can be adjusted by a driving device in the cooling system. Further, when T1 < T2, the height of the first guide fin and the second guide fin can be reduced by (T2-T1) millimeters.

[0073] In some embodiments, when the first temperature difference satisfies the set condition, new first and second temperatures are obtained after a set time interval, and a second temperature difference between the new first and second temperatures is determined. When the second temperature difference does not satisfy the set condition, the height of the first guide fin and the second guide fin in the merging portion is adjusted according to the second temperature difference.

[0074] In some scenarios, when the second temperature difference meets the set conditions and the difference between the second temperature difference and the first temperature difference is greater than the first set value, at least one first temperature and at least one second temperature are obtained at a set time interval; a new temperature difference is determined based on the first temperature and the second temperature obtained at the same set time interval, so that when the new temperature difference does not meet the set conditions, the heights of the first guide rib and the second guide rib in the confluence are adjusted respectively.

[0075] As an example, when the second temperature difference is determined to be 0.9 degrees and the first temperature difference is 0.4 degrees, and the first set value is 0.3, the difference between the second temperature difference and the first temperature difference is 0.5, which is greater than the first set value. At this time, it can be determined that there is a change in the temperature and / or flow rate of the water in the two inlet pipes. Further monitoring is then carried out so that when the temperature difference does not meet the set conditions, the height of the first guide rib and the second guide rib in the confluence is adjusted.

[0076] In some embodiments, taking a first inlet pipe as a high-temperature inlet pipe, a second inlet pipe as a low-temperature inlet pipe, a first outlet pipe as an outlet pipe on the same side as the high-temperature inlet pipe and roughly diagonally opposite to the low-temperature inlet pipe, and a second outlet pipe as an outlet pipe on the same side as the low-temperature inlet pipe and roughly diagonally opposite to the high-temperature inlet pipe as an example, the temperature of the first outlet pipe, T1, and the temperature of the second outlet pipe, T2, are determined. Further, it can be determined whether the absolute value of the temperature difference between the first and second temperatures, i.e., |T1-T2|, is less than 1. When the absolute value of the temperature difference is less than 1, there is no need to adjust the height of the guide rib. When the absolute value of the temperature difference is greater than or equal to 1, the magnitude of the first and second temperatures is further determined. When T1 < T2, the height of the guide rib is reduced by (T2-T1) millimeters; otherwise, the height of the guide rib is increased by (T1-T2) millimeters. Further, new temperatures of the first and second outlet pipes, T1 and T2, are obtained until the absolute value of the temperature difference is less than 1. Figure 7 As shown.
