Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic station technology, and in particular to a high-capacity fluid control hydraulic station. Background Technology
[0002] As industrial equipment develops towards higher efficiency, precision, and higher load capacity, hydraulic systems are widely used in many key fields, such as petrochemicals, mining machinery, and construction equipment. The core of a hydraulic system lies in the efficient transmission and control of hydraulic oil, and the temperature management of the hydraulic oil is one of the key factors for stable operation. Excessively high hydraulic oil temperatures not only lead to a decrease in oil viscosity but also accelerate oil oxidation and corrosion, reducing the system's efficiency and even causing equipment failure. Therefore, effective heat dissipation design is crucial for ensuring the long-term stable operation of hydraulic systems.
[0003] Traditional high-capacity fluid control hydraulic power units typically consist of main components such as hydraulic pumps, control valves, hydraulic cylinders, and oil tanks. Their working principle involves the hydraulic pump providing power to force fluid into the system's pipelines. Control valves then regulate the flow and pressure, transmitting hydraulic energy to actuators such as hydraulic cylinders or motors, thereby driving the mechanical device. These hydraulic power units are widely used in applications requiring high power and high-precision control, such as heavy machinery and engineering equipment. Their advantages include high energy transmission efficiency and strong load capacity, but they also require proper maintenance to prevent hydraulic oil contamination and leaks.
[0004] Existing fluid control hydraulic stations typically use natural ventilation to cool the oil tank. However, this method is ineffective when facing long-term high-load operation or extreme working environments, which can easily lead to unstable hydraulic oil temperature control and affect the long-term operation of the equipment. Utility Model Content

[0016] 1. In this utility model, the fan uses external airflow to drive air through the duct and guide plate, further delivering it to the oil tank and heat dissipation fins to dissipate heat and ensure that the oil tank and oil maintain a suitable temperature during operation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 - Figure 4The present invention provides an embodiment of a high-capacity fluid control hydraulic station, comprising a fixed base 1, a bracket 3 fixedly connected to the upper surface of the fixed base 1, an oil tank 2 fixedly connected to the upper surface of the bracket 3, heat dissipation fins 4 fixedly connected to the inner wall of the bracket 3, and an air supply assembly provided on the lower surface of the bracket 3. The air supply assembly is used to blow air to the oil tank 2 and the heat dissipation fins 4 for heat dissipation. By utilizing the principle of air cooling, the temperature of the oil tank 2 can be quickly reduced, and excess heat generated by the oil and equipment can be removed. A cooling assembly is provided on one side of the outer wall of the fixed base 1 for heat exchange between the oil tank 2 and the heat dissipation fins 4.
[0026] The air supply assembly includes a guide plate 5, the upper surface of which is fixedly connected to the lower surface of the bracket 3. A fan 6 is fixedly connected to the middle of the guide plate 5, and an air duct 7 is fixedly connected to the bottom of the guide plate 5. A filter screen 18 is fixedly connected to one end of the air duct 7. The cooling assembly includes a circulating water tank 8, one side of the outer wall of the circulating water tank 8 is fixedly connected to one side of the outer wall of the fixed base 1, and a circulating water pipe 9 is fixedly connected to the top of the circulating water tank 8. A coolant pipe 10 is fixedly connected to one end of the circulating water pipe 9.
[0027] Specifically, when the hydraulic station is running, the fan 6 is started, driving the external airflow. The air is guided to the oil tank 2 and the heat dissipation fins 4 through the air duct 7 and the guide plate 5, realizing heat exchange between the oil tank 2 and the heat dissipation fins 4. This ensures that the temperature of the oil tank 2 and the hydraulic oil is kept within the ideal range, avoiding excessive oil temperature that could affect the operating efficiency of the device. At the same time, the cooling water inside the circulating water tank 8 flows through the circulating water pipe 9 and the coolant pipe 10, exchanging heat with the oil tank 2 and the heat dissipation fins 4. In this process, the water cooling device removes heat from the oil and the surface of the oil tank 2, cooling it and ensuring that the oil temperature is always within a safe range. The combination of air cooling and water cooling makes the heat dissipation process more efficient and stable, effectively preventing the oil tank 2 and the oil temperature from becoming too high, preventing the oil from producing acidic substances and impurities due to excessive temperature, thereby reducing the failure rate of the device, extending the overall service life of the equipment, and ensuring the stability and efficiency of the hydraulic device under extreme loads.
[0028] Reference Figure 1 and Figure 2A hydraulic pump 11 is fixedly connected to one end of the oil tank 2. A valve 12 is installed at the output end of the hydraulic pump 11. An oil delivery pipe 13 is fixedly connected to the output end of the valve 12. A filter 14 is installed in the middle of the oil delivery pipe 13 to remove impurities, particles, and contaminants from the oil, ensuring that the oil entering the hydraulic device is clean and free of any particles that may affect the normal operation of the equipment. This helps to extend the service life of key components in the hydraulic device and reduce the occurrence of failures. After the oil passes through the filter 14, a pressure control valve assembly 15 is fixedly connected to one end of the oil delivery pipe 13. The internal fixed connection of the 15 is a connecting pipe 16, one end of which is equipped with a frequency converter 17. The outer wall of the coolant pipe 10 is set on the outer wall of the oil tank 2 and inside the heat dissipation fins 4. The lower surface of the filter 14 is fixedly connected to the upper surface of the fixed base 1. The filter 14 is used to filter the oil. The lower surface of the pressure control valve group 15 is fixedly connected to the upper surface of the fixed base 1. The frequency converter 17 is fixedly connected to the top of the fixed base 1. The bottom of the frequency converter 17 is equipped with an output pipe. The outer wall of the heat dissipation fins 4 is attached to the outer wall of the oil tank 2. The heat dissipation fins 4 are used to dissipate heat from the oil tank 2.
[0029] Specifically, hydraulic pump 11 first draws hydraulic oil from oil tank 2 and delivers it, ensuring smooth oil flow. Valve 12 controls the oil delivery pipe 13 to open when needed and close as required, preventing oil waste or flow to the wrong parts. Next, the oil flows through filter 14 and then through pressure control valve group 15, where the oil pressure is adjusted according to the device's needs to ensure each component receives appropriate oil pressure, thus guaranteeing the device's stability and efficiency. Afterward, the oil is delivered to frequency converter 17 via connecting pipe 16, where the speed is adjusted for further control. The flow rate of the hydraulic fluid ensures that the hydraulic unit can respond flexibly under different working conditions. In addition, the hydraulic station is equipped with two oil tanks 2, which effectively avoids the shutdown of the entire unit due to the failure of a single oil tank 2. When the oil in one oil tank 2 becomes contaminated or the filter 14 is blocked, the unit can automatically switch to the other oil tank 2 to replace or maintain the oil, ensuring that the hydraulic unit can always operate smoothly. At the same time, the design of two oil tanks 2 also effectively reduces the risk of the temperature of a single oil tank 2 being too high, preventing the equipment from being damaged due to the expansion of the oil at high temperature, and maintaining the long-term stability of the hydraulic unit.
[0030] Working principle: When a high-capacity fluid control hydraulic station is required, the hydraulic pump 11 is first started to draw hydraulic oil from the oil tank 2 and pressurize and deliver it. During this process, the oil delivery pipe 13 is opened and closed through the valve 12. Then, the filter 14 removes impurities, particles and contaminants from the oil to ensure the cleanliness of the hydraulic oil. Finally, the oil is delivered to the frequency converter 17 through the pressure control valve group 15 and the connecting pipe 16. During this process, since there are two oil tanks 2 above the fixed base 1, it can avoid the machine from being shut down due to the damage of a single oil tank 2. It can also be used for maintenance when the filter 14 is clogged. It can also effectively prevent the temperature of a single oil tank 2 from getting too high, reducing the thermal expansion and deterioration of the oil.
[0031] In addition, the start-up fan 6 drives external air through the air duct 7 and the guide plate 5 to the oil tank 2 and the heat dissipation fins 4, thereby dissipating heat from the oil tank 2 and the heat dissipation fins 4. At the same time, the cooling water inside the circulating water tank 8 is circulated through the circulating water pipe 9 and transported inside the coolant pipe 10. While the cooling water is circulating, it will exchange heat with the heat dissipation fins 4 and the oil tank 2. Combined with the air cooling of the fan 6, efficient and stable heat dissipation is achieved, avoiding excessively high temperatures in the oil tank 2 and the internal oil, which can easily form acidic substances and impurities.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
