Description

Technical Field

[0001] The invention relates to a fast cooling hydraulic pump station, in particular to a fast cooling hydraulic pump station applied in the field of hydraulic technology. Background Art

[0002] During the long-term operation of the existing hydraulic pump station, the hydraulic oil continuously generates a lot of heat due to shearing and friction, causing the hydraulic oil temperature to rise continuously. If the hydraulic oil temperature is too high, its viscosity and lubrication performance will be reduced, accelerating the wear of hydraulic components. In severe cases, it will also lead to oil degradation, aging and failure of rubber seals, and other problems, ultimately affecting the reliability and service life of the hydraulic system. Therefore, it is of great significance to effectively control the hydraulic oil temperature and achieve rapid cooling of the hydraulic pump station.

[0003] Chinese invention patent CN112443519 discloses an integral sealed hydraulic pump station, which uses a temperature control valve to control the coolant and cooling gas to cool the oil tank. This design achieves the regulation of hydraulic oil temperature to a certain extent through multi-stage cooling and temperature feedback control. However, this patent mainly relies on externally supplied cooling media, such as coolant and cooling gas, to achieve the cooling function, which consumes a lot of energy. At the same time, the temperature control valve is a passive control, and the adjustment accuracy and response speed are limited.

[0004] Chinese invention patent CN114109937 discloses a mobile hydraulic pump station with fast cooling speed, focusing on the design of the mobile fixing mechanism of the hydraulic pump station.

[0009] As a further improvement of the present application, the cooling pipe and the overflow pipe are connected to each other at one end away from the diverter block, and the connected end is fixedly connected to the oil tank, and the detection tube is fixedly connected to the regulating valve at one end close to the fixed block.

[0010] As a further improvement of the present application, one end of the detection tube close to the fixed block passes through the fixed block and the bimetallic strip, and one end of the detection tube passing through the bimetallic strip is fixedly connected with a shunt tube, which is located between the bimetallic strip and the shunt block.

[0011] As another improvement of the present application, the turbine device includes a shell fixedly connected to one end of the fairing away from the fixed block, a turbine is rotatably connected inside the shell, a power shaft is fixedly connected to the turbine, a liquid inlet pipe is fixedly connected to the outer end of the shell, and the liquid inlet pipe is connected to the hydraulic pump system.

[0012] As another improvement supplement of the present application, a synchronous belt is arranged at the outer end of the power shaft in contact with the cooling fan, and the synchronous belt is arranged at one end away from the power shaft in contact with the cooling fan.

[0013] As another improved supplement of the present application, the cooling fan includes a cooling shaft arranged in contact with the synchronous belt, the cooling shaft is fixedly connected to a cooling impeller at one end away from the synchronous belt, the cooling impeller is an axial flow impeller, and a bracket is fixedly connected to the outer end of the turbine device casing, and the bracket is rotatably connected to the cooling shaft.

[0014] As another improvement of the present application, the cooling device includes a heat absorption tube fixedly connected to the outer end of the cooling tube, a heat dissipation tube is fixedly connected to the top end of the heat absorption tube, a plurality of heat sinks arranged in a circumferential array are fixedly connected to the heat dissipation tube, a heat dissipation guide tube is fixedly connected to the outer end of the heat sink, the heat dissipation guide tube is rotatably connected to the cooling impeller, the heat absorption tube and the heat dissipation tube are interconnected, and the heat absorption tube and the heat dissipation tube are both filled with easily evaporated heat transfer fluid.

[0015] The steps include:

[0016] S1, residual pressure drive;

[0017] S2, temperature sensing;

[0018] S3, automatic traffic allocation;

[0019] S4, residual pressure drives active cooling;

[0020] S5, automatic temperature feedback adjustment;

[0021] S6. Automatic temperature feedback adjustment control.

[0022] In summary, this application has the following beneficial effects:

[0023] 1. By installing a bimetallic strip in the hydraulic pump station and utilizing the bimetallic strip's automatic sensing characteristics of the hydraulic oil temperature, real-time monitoring of the hydraulic oil temperature is achieved. When the hydraulic oil temperature changes, the bimetallic strip will produce a corresponding deformation, thereby driving the diverter block to rotate and automatically adjusting the flow distribution ratio of the cooling pipe and the overflow pipe. This temperature adaptive control method based on the bimetallic strip avoids the use of electronic sensors and controllers, simplifies the system structure, and improves reliability.

[0024] 2. The present invention cleverly utilizes the unused pressure energy during the operation of the hydraulic pump station. By setting up a turbine device and a liquid inlet pipe, the residual pressure of the hydraulic oil is introduced into the turbine device to drive the turbine to rotate, thereby driving the cooling fan to rotate at high speed, forming a forced airflow around the cooling device, and significantly accelerating the heat dissipation process. This method of heat dissipation driven by residual pressure does not require an additional power source, fully utilizes the system's own energy, and improves energy utilization efficiency.

[0025] 3. The cooling device adopts a design combining a heat absorbing tube and a heat dissipating tube, which are filled with easily evaporable heat transfer fluid. When the high-temperature hydraulic oil flows through the cooling tube, the heat transfer fluid absorbs the heat of the hydraulic oil and evaporates quickly, carrying a large amount of heat to the heat dissipating tube. On the surface of the heat dissipating tube, the heat transfer fluid condenses and releases heat, efficiently releasing the heat to the surrounding environment. At the same time, the rotating cooling impeller accelerates the air flow around the heat dissipating tube, further enhancing the heat dissipation effect. This composite heat dissipation method of phase change heat transfer combined with forced convection has high heat transfer efficiency and fast heat dissipation speed.

[0026] 4. The present invention has designed a unique automatic temperature feedback regulation loop. Part of the hydraulic oil cooled by the cooling device is introduced into the bimetallic strip through the detection tube, so that the temperature of the bimetallic strip is consistent with the temperature of the cooled hydraulic oil. When the temperature of the hydraulic oil is too high, the bimetallic strip senses the high temperature and deforms, driving the diverter block to increase the opening of the cooling tube, allowing more high-temperature hydraulic oil to flow through the cooling device for cooling; when the temperature of the hydraulic oil is too low, the bimetallic strip senses the low temperature and resets, driving the diverter block to reduce the opening of the cooling tube, reducing the flow of hydraulic oil flowing through the cooling device, and avoiding the hydraulic oil temperature being too low to affect its fluidity. This temperature feedback regulation mechanism realizes the automatic optimization control of the hydraulic oil temperature, which not only ensures rapid cooling, but also prevents overcooling, and maintains the stable operation of the system.

[0027] 5. By setting a manual regulating valve on the detection tube, the flow of cooled hydraulic oil introduced into the bimetallic strip can be flexibly adjusted. When the regulating valve is opened, more cooled hydraulic oil enters the bimetallic strip, making the temperature feedback control more sensitive; when the regulating valve is opened, the amount of cooled hydraulic oil introduced into the bimetallic strip is reduced, and the sensitivity of the temperature feedback control is reduced. This manually intervened temperature feedback control method provides greater flexibility for the operation adjustment of the system, and can optimize the temperature control strategy according to the actual working conditions.

[0028] 6. The present invention adopts a modular and compact structural layout. It integrates multiple functions such as temperature sensing, flow distribution, residual pressure utilization, forced air cooling, phase change heat transfer, etc. into a compact device, reducing the volume and complexity of the system. Key components such as adjustment plates, fixing blocks, diverter boxes, turbine devices, cooling devices, etc. all adopt optimized structural designs to ensure good sealing, strength and heat transfer performance. The modular design also facilitates the processing, manufacturing, assembly, maintenance, replacement and upgrading of components.

[0029] 7. The present invention mostly adopts pure mechanical design, such as bimetallic temperature sensing, flow distribution of shunt block, and utilization of residual pressure of turbine device, etc., avoiding complex electronic control systems and sensors, and improving the reliability and environmental adaptability of the system. Only a simple manual valve is used in the temperature feedback control loop, which is convenient for manual adjustment according to needs, taking into account the degree of automation and manual control flexibility. Compared with the traditional hydraulic station heat dissipation solution, the present invention has the advantages of high heat dissipation efficiency, precise temperature control, good system reliability, high energy utilization, etc. In practical applications, it can significantly improve the thermal management level and operation stability of the hydraulic system, and has broad prospects for promotion and application.

[0042] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0043] The first implementation method:

[0044] Figure 1-Figure 10 Shown.

[0045] A hydraulic pump station with rapid cooling comprises a symmetrically arranged adjusting plate 1, a fixed block 2 is clamped between one end of the symmetrically arranged adjusting plate 1, a diverter box 3 is fixedly connected to the end of the symmetrically arranged adjusting plate 1 away from the fixed block 2, a bimetallic strip 4 is fixedly connected to the end of the fixed block 2 close to the diverter box 3, a diverter block 5 is fixedly connected to the end of the bimetallic strip 4 away from the diverter box 3, a cooling pipe 6 and an overflow pipe 7 are fixedly connected to the end of the diverter box 3 away from the bimetallic strip 4, a cooling device 8 is fixedly connected to the outer end of the cooling pipe 6, a guide cover 9 is fixedly connected to the end of the symmetrically arranged adjusting plate 1 away from the diverter block 5, a detection tube 10 is fixedly connected between the cooling pipe 6 and the fixed block 2, a turbine device 11 is fixedly connected to the end of the guide cover 9 away from the adjusting plate 1, and a cooling fan 12 is provided between the turbine device 11 and the cooling device 8.

[0046] The symmetrically arranged adjustment plate 1 plays a supporting and fixing role and provides an installation basis for other components. The symmetrical design of the adjustment plate 1 can improve the stability and balance of the entire device and facilitate modular installation and maintenance.

[0047] The fixing block 2 is clamped between the adjusting plates 1 and is used to connect and fix the bimetallic strip 4 and other components, so as to realize a reliable connection between the bimetallic strip 4 and the adjusting plate 1 and ensure the stability and sensitivity of the bimetallic strip 4 .

[0048] The diverter box 3 is fixedly connected to the end of the regulating plate 1 away from the fixed block 2, and an oil return chamber is formed inside the diverter box for oil diversion. The return oil can be divided into two paths: cooling and overflow. The high-temperature oil first enters the cooling pipe 6 for cooling, and the low-temperature oil flows out directly through the overflow pipe 7, reducing the load of the cooling device 8 and improving the heat dissipation efficiency.

[0049] The bimetallic strip 4 is fixedly connected to one end of the fixed block 2 close to the shunt box 3. It is made of two metal materials with different thermal expansion coefficients and is sensitive to temperature changes. It can drive the shunt block 5 to rotate and sense the return oil temperature changes. No electronic sensor is required, which simplifies the system structure. The bimetallic strip 4 controls the rotation angle of the shunt block 5 to achieve adaptive oil temperature adjustment and improve temperature control accuracy.

[0050] The shunt block 5 is fixedly connected to the end of the bimetallic strip 4 away from the shunt box 3, and can rotate around the axis driven by the bimetallic strip 4 to adjust the opening area ratio of the cooling pipe 6 and the overflow pipe 7. The flow ratio of the cooling pipe 6 and the overflow pipe 7 can be automatically adjusted according to the oil temperature signal fed back by the bimetallic strip 4, so as to realize adaptive temperature control with more cooling at high temperature and less cooling at low temperature.

[0051] The cooling pipe 6 is fixedly connected to one end of the shunt box 3 away from the bimetallic strip 4, and communicates with the return oil chamber in the shunt box 3, so as to introduce the high-temperature return oil into the cooling device 8 for heat dissipation and cooling. The high-temperature return oil can be preferentially guided into the cooling device 8 to improve the heat dissipation efficiency and reduce the system temperature.

[0052] The overflow pipe 7 is fixedly connected to one end of the diverter box 3 away from the bimetallic strip 4, and is communicated with the return oil chamber in the diverter box 3, so as to directly discharge the return oil with a lower temperature. The return oil with a lower temperature can be directly led out, thereby reducing the amount of oil entering the cooling device 8, reducing the load on the cooling system, and saving energy consumption.

[0053] The cooling device 8 is fixedly connected to the outer end of the cooling pipe 6, and adopts a heat absorption pipe-heat dissipation pipe phase change heat transfer structure, with a built-in easily evaporable thermal conductive liquid, which can efficiently absorb the return oil heat and dissipate it into the environment. It utilizes the phase change heat transfer principle, has high heat transfer efficiency, and cooperates with forced air cooling to achieve fast and efficient heat dissipation and cooling.

[0054] The guide cover 9 is fixedly connected to the end of the regulating plate 1 away from the diverter block 5, and the return oil is introduced into the diverter box 3 in an orderly manner, which can optimize the return oil flow path, reduce flow resistance, prevent return oil leakage, and improve diversion efficiency.

[0055] The detection tube 10 is fixedly connected between the cooling tube 6 and the fixed block 2, and part of the cooled return oil is introduced into the bimetallic strip 4 for temperature feedback. A temperature feedback loop can be constructed to feed back the cooling effect to the bimetallic strip 4 in real time, thereby realizing closed-loop temperature control, improving system stability, and avoiding temperature fluctuations.

[0056] The turbine device 11 is fixedly connected to the end of the air deflector 9 away from the adjustment plate 1. The residual pressure of the return oil is used to drive the internal turbine to rotate, thereby converting the pressure energy into mechanical energy to drive the cooling fan 12. The residual energy of the hydraulic system can be fully utilized, and no external power is required, thus saving energy consumption. The high-speed rotation of the turbine drives the cooling fan 12 to rotate, which can significantly enhance the heat dissipation performance of the cooling device 8.

[0057] The cooling fan 12 is arranged between the turbine device 11 and the cooling device 8, and is coaxially connected to the turbine shaft. It can rotate at high speed under the drive of the turbine to accelerate the air flow around the cooling device 8, generate forced convection, speed up the heat exchange between the cooling device 8 and the environment, improve the heat dissipation efficiency, and quickly cool down the system.

[0058] The bimetallic strip 4 senses temperature for feedback, the shunt block 5 adaptively adjusts the oil circuit, the cooling device 8 efficiently transfers heat through phase change, the turbine device 11 and the cooling fan 12 drive forced air cooling with surplus energy, and a variety of heat dissipation and temperature control technologies are highly integrated and optimized. The overall structure is compact and reasonable, which achieves a significant improvement in heat dissipation performance and temperature control accuracy, can greatly improve the thermal management level and operational reliability of the hydraulic system, and has broad prospects in engineering applications.

[0059] The second implementation method:

[0060] Figure 1-Figure 10 Shown.

[0062] The cooling pipe 6 and the overflow pipe 7 are connected to each other at one end away from the diverter block 5 , and the connected end is fixedly connected to the oil tank. The detection pipe 10 is fixedly connected to the regulating valve 13 at one end close to the fixed block 2 .

[0063] One end of the detection tube 10 close to the fixed block 2 passes through the fixed block 2 and the bimetallic strip 4 , and one end of the detection tube 10 passing through the bimetallic strip 4 is fixedly connected with a shunt tube, which is located between the bimetallic strip 4 and the shunt block 5 .

[0064] The turbine device 11 includes a shell fixedly connected to the end of the deflector 9 away from the fixed block 2, a turbine is rotatably connected in the shell, a power shaft 14 is fixedly connected to the turbine, and a liquid inlet pipe 17 is fixedly connected to the outer end of the shell, and the liquid inlet pipe 17 is connected to the hydraulic pump system.

[0065] The outer end of the power shaft 14 is provided with a synchronous belt in contact with it, and the end of the synchronous belt away from the power shaft 14 is provided with a synchronous belt in contact with the cooling fan 12 .

[0066] The cooling fan 12 includes a cooling shaft 15 that is arranged in contact with the synchronous belt, and a cooling impeller 16 is fixedly connected to one end of the cooling shaft 15 away from the synchronous belt.

[0067] The cooling impeller 16 is an axial flow impeller. A bracket is fixedly connected to the outer end of the turbine device 11 shell, and the bracket is rotatably connected to the cooling shaft 15.

[0068] The cooling device 8 includes a heat absorption tube fixedly connected to the outer end of the cooling tube 6, a heat dissipation tube fixedly connected to the top of the heat absorption tube, a plurality of heat dissipation fins arranged in a circumferential array fixedly connected to the heat dissipation tube, a heat dissipation guide tube fixedly connected to the outer end of the heat dissipation fin, the heat dissipation guide tube is rotatably connected to the cooling impeller 16, the heat absorption tube and the heat dissipation tube are interconnected, and the heat absorption tube and the heat dissipation tube are both filled with easily evaporated heat transfer fluid.

[0069] The outer end of the diverter block 5 is an arc-shaped structure, which can rotate in the diverter box 3 under the drive of the bimetallic strip 4 to adjust the opening area ratio of the cooling pipe 6 and the overflow pipe 7. The diverter block 5 adopts an arc-shaped structure and forms a sealing fit with the inner wall of the diverter box 3, which can achieve smooth and accurate flow regulation and reduce oil leakage.

[0070] An oil return chamber is formed inside the diverter box 3, and its end close to the diverter block 5 cooperates with the outer end to form a sealed rotating structure. The matching design of the inner and outer ends of the diverter box 3 can provide stable rotation support for the diverter block 5, ensuring the adjustment accuracy and reliability.

[0071] The bimetallic strip 4 is located between the cooling pipe 6 and the overflow pipe 7, senses the change in the return oil temperature, and drives the diverter block 5 to rotate. The bimetallic strip 4 is located between the cooling pipe 6 and the overflow pipe 7, and can directly sense the comprehensive temperature of the oil passing through the two pipelines, reflecting the overall thermal state of the system, and the control is more accurate.

[0072] The cooling pipe 6 and the overflow pipe 7 are connected to each other at one end away from the diverter block 5, and an oil tank is fixed to the connecting end to realize the confluence of the cooling circuit and the bypass circuit. The cooled oil and the bypass oil can be mixed to balance the system temperature and avoid local overcooling or overheating.

[0073] The regulating valve 13 is fixedly connected to one end of the detection tube 10 near the fixed block 2, and is used to manually adjust the flow of cooling oil introduced into the bimetallic strip 4. The temperature feedback amount can be conveniently adjusted, and the response sensitivity of the bimetallic strip 4 can be flexibly controlled to meet the requirements of different working conditions.

[0074] The end of the detection tube 10 close to the fixed block 2 passes through the fixed block 2 and the bimetallic strip 4, and is connected to a shunt tube at the end passing through the bimetallic strip 4. The shunt tube is located between the bimetallic strip 4 and the shunt block 5, and introduces part of the cooled oil into the bimetallic strip 4. The cooling effect can be fed back to the bimetallic strip 4 in real time to form a closed-loop temperature control system. At the same time, the shunt tube directly introduces the cooling oil into the bimetallic strip 4, thereby improving the heat exchange efficiency and accelerating the response speed of the bimetallic strip 4.

[0075] The turbine device 11 includes a shell connected to the end of the deflector 9 away from the fixed block 2, a turbine is rotatably connected in the shell, a power shaft 14 is fixedly connected to the turbine, and the outer end of the shell is fixedly connected to the liquid inlet pipe 17, which is connected to the hydraulic pump system, and the turbine is driven to rotate by the residual pressure of the return oil.

At the same time, the reasonable design of the shell and the turbine can realize the efficient conversion of pressure energy into mechanical energy.

[0076] The outer end of the power shaft 14 is connected to the cooling fan 12 through a synchronous belt to transmit the mechanical energy of the turbine to the cooling fan 12. The transmission method of the power shaft 14 and the synchronous belt has high precision and good synchronization, which can effectively reduce energy loss and improve transmission efficiency.

[0077] The cooling fan 12 includes a cooling shaft 15 connected to a synchronous belt. The cooling shaft 15 is fixedly connected to a cooling impeller 16 at one end away from the synchronous belt. The cooling fan 15 rotates at high speed under the drive of the turbine to accelerate the air flow around the cooling device 8. The axial flow design of the cooling fan 12 can generate high-speed straight airflow, enhance the convective heat exchange on the surface of the cooling device 8, and significantly improve the heat dissipation efficiency.

[0078] The cooling impeller 16 adopts an axial flow design and is fixedly connected to the casing of the turbine device 11 through a bracket. The bracket is rotatably connected to the cooling shaft 15 to provide stable support for the cooling fan 12. The blades are aerodynamically optimized to maintain good aerodynamic performance and structural strength at high speeds. The fixed connection between the bracket and the casing ensures the coaxiality and stability of the cooling fan 12.

[0079] The cooling device 8 includes a heat absorption tube and a heat dissipation tube connected to the cooling tube 6, a heat sink in a circular array is fixedly connected to the heat dissipation tube, and a heat dissipation guide tube is arranged on the periphery of the heat dissipation fin to cooperate with the cooling impeller 16. The heat absorption tube and the heat dissipation tube are filled with easily evaporable heat transfer fluid, and the phase change heat transfer principle is utilized to quickly absorb and release heat. The phase change heat transfer design of the cooling device 8 has a high heat transfer coefficient and good heat dissipation efficiency. The heat sink array increases the heat dissipation area. The heat dissipation guide tube cooperates with the cooling fan 12 to further enhance the heat dissipation effect. The overall structure is compact and the heat dissipation capacity is strong, which can significantly improve the cooling speed of the hydraulic system.

[0080] The third implementation method:

[0081] Figure 1-Figure 10 Shown.

[0082] The steps include:

[0083] S1, residual pressure drive;

[0084] During the operation of the hydraulic pump station, there is unused hydraulic oil under pressure, which flows into the turbine device 11 through the liquid inlet pipe 17 to drive the turbine to rotate, and the rotation of the turbine drives the power shaft 14 connected thereto to rotate;

[0085] S2, temperature sensing;

[0086] The hydraulic oil flows from the turbine device 11 into the deflector 9 and then flows from the deflector 9 into between the adjustment plate 1 and the shunt box 3. At this time, the bimetallic strip 4 begins to deform under the influence of the hydraulic temperature. The deformation of the bimetallic strip 4 drives the shunt block 5 connected thereto to rotate. The shunt block 5 distributes and adjusts the flow in the cooling pipe 6 and the overflow pipe 7 during the rotation process.

[0087] S3, automatic traffic allocation;

[0088] When the temperature of the hydraulic oil is high, the bimetallic strip 4 bends and drives the shunt block 5 to rotate in the direction close to the overflow pipe 7. During the rotation of the shunt block 5, the overflow pipe 7 is gradually blocked by the shunt block 5. At this time, the high-temperature hydraulic oil mainly flows out through the cooling pipe 6. When the temperature of the hydraulic oil is relatively low, the bimetallic strip 4 bends and drives the shunt block 5 to rotate in the direction close to the cooling pipe 6. During the rotation of the shunt block 5, the cooling pipe 6 is gradually blocked by the shunt block 5. At this time, the hydraulic oil with a lower temperature mainly flows out through the overflow pipe 7.

[0089] S4, residual pressure drives active cooling;

[0090] When the hydraulic oil flows through the cooling pipe 6, the heat of the hydraulic oil causes the heat transfer fluid in the heat absorption pipe on the cooling device 8 to evaporate, and the evaporated heat transfer fluid brings the heat to the heat dissipation pipe, and then dissipates the heat from the heat dissipation pipe to the surrounding environment. At this time, the power shaft 14 drives the cooling shaft 15 and the cooling impeller 16 to rotate through the synchronous belt. When the cooling impeller 16 rotates, it pushes the air flow in the guide tube to flow, thereby accelerating the heat dissipation.

[0091] S5, automatic temperature feedback adjustment;

[0092] When the hydraulic oil flowing through the cooling pipe 6 is cooled by the cooling device 8, part of the hydraulic oil flows back into the bimetallic strip 4 through the detection tube 10. At this time, the hydraulic oil flows through the middle of the bimetallic strip 4, and the temperature of the hydraulic oil causes the temperature of the bimetallic strip 4 to change accordingly. If the temperature of the hydraulic oil returning from the cooling pipe 6 is high, the bimetallic strip 4 increases the opening of the cooling pipe 6, thereby increasing the flow of hydraulic oil flowing through the cooling pipe 6 and cooling more hydraulic oil. If the temperature of the hydraulic oil returning from the cooling pipe 6 is low, the bimetallic strip 4 reduces the opening of the cooling pipe 6, thereby reducing the flow of hydraulic oil flowing through the cooling pipe 6, thereby making it less likely for the hydraulic oil to be overheated or overcooled to affect its fluidity and increase the burden on the hydraulic pump.

[0093] S6, automatic temperature feedback adjustment control;

[0094] During use, the response degree of step S5 can be manually adjusted through the regulating valve 13 as needed. When the temperature automatic feedback regulation needs to be more sensitive, the opening of the regulating valve 13 is increased to allow more hydraulic oil to flow back into the bimetallic strip 4 after being cooled by the cooling device 8. When the temperature automatic feedback regulation sensitivity needs to be reduced, the opening of the regulating valve 13 is reduced to allow less hydraulic oil to flow back into the bimetallic strip 4 after being cooled by the cooling device 8. Automatic temperature feedback regulation control can be achieved by manually adjusting the flow rate of the hydraulic oil flowing back into the bimetallic strip 4 after cooling.

[0095] The unused pressure energy during the operation of the hydraulic pump station can be used to drive the turbine device 11 and the power shaft 14 through the liquid inlet pipe 17, without the need for an additional drive device, thus making full use of the system's own residual pressure energy, saving energy and improving system efficiency.

[0096] The bimetallic strip 4 can directly sense the change of hydraulic oil temperature, and drive the diverter block 5 to rotate through deformation, thereby adjusting the flow distribution of the cooling pipe 6 and the overflow pipe 7. This temperature sensing method is simple and reliable, does not require electronic sensors and controllers, and reduces system complexity and cost.

[0097] According to the temperature of the hydraulic oil, the bimetallic strip 4 and the diverter block 5 can automatically adjust the flow ratio of the cooling pipe 6 and the overflow pipe 7. When the oil temperature is high, more oil flows through the cooling pipe 6 for cooling; when the oil temperature is low, more oil flows directly out through the overflow pipe 7. This automatic flow distribution mechanism can accurately control the cooling amount, avoid overcooling or undercooling, and ensure that the hydraulic oil temperature is within the optimal range.

[0098] When the hydraulic oil flows through the cooling pipe 6, its heat can be efficiently transferred and dissipated through the heat absorbing pipe and the heat dissipating pipe in the cooling device 8. At the same time, the power shaft 14 drives the cooling shaft 15 and the cooling impeller 16 to rotate at high speed through the synchronous belt, accelerating the air flow in the heat dissipation guide tube and enhancing the heat dissipation effect. This active cooling method driven by residual pressure has high heat dissipation efficiency and fast cooling speed.

[0099] After being cooled by the cooling device 8, part of the hydraulic oil flows back into the bimetallic strip 4 through the detection tube 10, so that the temperature of the bimetallic strip 4 is synchronized with the temperature of the cooled oil in real time. When the return oil temperature is high, the bimetallic strip 4 will automatically increase the opening of the cooling tube 6 to increase the cooling flow; when the return oil temperature is low, the bimetallic strip 4 will automatically reduce the opening of the cooling tube 6 to reduce the cooling flow. This automatic temperature feedback adjustment mechanism realizes closed-loop temperature control and can dynamically optimize the cooling amount according to the actual heat dissipation effect, which not only avoids the hydraulic oil temperature from being too high, but also prevents excessive cooling from affecting the fluidity of the oil, and reduces the burden on the hydraulic pump.

[0100] By setting a manual regulating valve 13 on the detection tube 10, the oil flow rate of the temperature feedback loop can be flexibly controlled. When the temperature feedback sensitivity needs to be improved, the opening of the regulating valve 13 is increased to allow more cooled oil to enter the bimetal 4; when the temperature feedback sensitivity needs to be reduced, the opening of the regulating valve 13 is reduced to allow less cooled oil to enter the bimetal 4. This manual intervention feedback regulation control method provides a flexible tuning method for the system, and can conveniently optimize the temperature control strategy according to different working conditions.

[0101] In summary, this rapid cooling hydraulic pump station uses a variety of technologies such as residual pressure drive, temperature sensing, automatic flow distribution, active cooling, temperature feedback adjustment, etc. to build a highly adaptive, efficient and accurate hydraulic oil temperature control system. The various components cooperate with each other to form a closed-loop control mechanism of perception-regulation-heat dissipation-feedback-optimization. It can dynamically adjust the cooling strategy according to oil temperature changes and heat dissipation requirements to maximize the effectiveness of the heat dissipation system. Compared with traditional hydraulic station heat dissipation solutions, this system has the advantages of fast response speed, high temperature control accuracy, low energy consumption, and good reliability. It can improve the thermal management level and operating stability of the hydraulic system, extend the service life of the system, and has broad application prospects in the field of high-end equipment.

[0102] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
