Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic pump stations, specifically, it relates to an energy-saving hydraulic pump station. Background Technology

[0002] A hydraulic power unit is a hydraulic device that supplies oil according to the required flow direction, pressure and flow rate. Existing traditional hydraulic power units consist of an oil tank, motor, vane pump, radiator, solenoid valve and energy storage tank. Its working principle is that the motor is energized and rotates to drive the vane pump to output hydraulic pressure. That is, the vane pump works to pump the liquid out of the oil tank. When the pressure reaches the set value, the pressure relief valve opens and the excess liquid flows back to the oil tank.

[0003] CN221591422U discloses an energy-saving hydraulic power unit. By setting up a water pump, a cooling mechanism, and a temperature sensor, the water pump and cooling mechanism can gradually cool the water inside the water tank, and the temperature sensor can monitor the water temperature to ensure that the water temperature is within a suitable range, thereby cooling the hydraulic oil. The unit also includes a servo motor, a hydraulic pump, and a solenoid valve. The servo motor drives the hydraulic pump, which in turn controls the hydraulic equipment, and the solenoid valve controls the flow rate of the hydraulic oil.

[0004] In existing technologies, components such as pumps, valves, and cylinders in hydraulic systems will wear out during long-term operation. The metal particles or fragments generated by this wear will enter the hydraulic oil and become part of the impurities. These impurities will affect the normal operation of the equipment and limit the practicality of the device to a certain extent.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

The upper sealing cover 20 is sealed to the inner wall of the filter box 7. The filter screens 25 are sealed together. A collection chamber 23 is provided at the bottom of the filter box 7. A drain port 24 is provided at the bottom of the collection chamber 23. A cooling mechanism 9, a protection box 10 and a temperature control box 13 are provided inside the installation box 2. A temperature control pipe 16 is provided inside the temperature control box 13. The temperature control pipe 16 has an S-shaped bend structure. A heating chamber 14 is provided at the bottom of the temperature control box 13. An electric heating component is provided inside the heating chamber 14. A sealing partition 15 is provided at the top of the heating chamber 14. The sealing partition 15 is made of thermally conductive material and is used to effectively heat the liquid inside the temperature control box 13.

[0021] The base is equipped with a hydraulic pump 4 and a fixed box 3 on the side of the oil tank 5. The oil outlet of the hydraulic pump 4 is connected to a temperature-regulating oil inlet pipe 11, which is connected to the inlet of the temperature-regulating pipe 16 to supply oil into the temperature-regulating pipe 16.

[0022] The outlet end of the temperature regulating pipe 16 is connected to the oil outlet pipe 8. Both ends of the temperature regulating pipe 16 are equipped with pipe joints 27. The connection positions of the temperature regulating oil inlet connecting pipe 11, the oil outlet pipe 8 and the pipe joints 27 are equipped with connecting caps 12 and sealing rings 28 respectively. The connecting caps 12 and the pipe joints 27 are connected by threads to achieve a quick and sealed connection between the temperature regulating pipe 16 and the temperature regulating oil inlet connecting pipe 11 and the oil outlet pipe 8.

[0023] A water pump is installed inside the protection box 10. The water pump is connected to the temperature control box 13 through a second connecting pipe 19. The cooling mechanism 9 is connected to the temperature control box 13 through a first connecting pipe 18. The first connecting pipe 18 is located at the upper part of the temperature control box 13, and the second connecting pipe 19 is located at the lower part of the temperature control box 13. It is used to cool down the liquid inside the temperature control box 13.

[0024] The connection points of connecting pipe 18 and connecting pipe 2 19 to the temperature control box 13 are set diagonally on the temperature control box 13 to ensure effective circulation of the liquid inside the temperature control box 13.

[0025] The fixed box 3 is equipped with a servo motor and hydraulic components. The fixed box 3 is connected to the hydraulic pump 4 through a pipe. The filter box 7 and the return oil pipe 6 are connected through a pipe connector cap 12 to facilitate quick assembly and disassembly of the filter box 7 and the return oil pipe 6.

[0026] The working principle of this utility model is as follows: Example 1: During the operation of the hydraulic station, the temperature sensor 17 can effectively detect the temperature. When the ambient temperature of the hydraulic pump station is low, the hydraulic oil is more viscous. The device is equipped with a control unit, a microcontroller, and a control circuit to control the heating components in the heating chamber 14 to turn on, effectively heating the liquid in the temperature control box 13. Through heat transfer, the oil in the temperature control pipe 16 is heated to prevent the hydraulic oil from condensing, further ensuring the normal operation of the equipment. The control unit, microcontroller, control circuit, and temperature sensor 17 all adopt existing technologies. Example 2: As the hydraulic station continues to operate, the temperature of the hydraulic oil will continuously rise. The water pump in the protection tank 10 draws water from the temperature control tank 13 through the connecting pipe 2 19 and supplies it to the cooling mechanism 9. The cooling mechanism 9 cools the water. The cooled water flows back into the temperature control tank 13 through the connecting pipe 1 18. The connection positions of the connecting pipe 1 18, the connecting pipe 2 19 and the temperature control tank 13 are diagonally arranged on the temperature control tank 13 to ensure that the water in the temperature control tank 13 can circulate fully and effectively during the cooling process. The water temperature inside the temperature control tank 13 can then gradually decrease, thereby cooling the hydraulic oil in the temperature control pipeline 16. The temperature sensor 17 monitors the water temperature and controls the water pump and cooling mechanism 9 to maintain the water temperature within a suitable range, thereby controlling the hydraulic oil temperature within a suitable range. The cooling mechanism 9 adopts existing technology. Example 3: The hydraulic pump 4 of the hydraulic station supplies hydraulic oil from the oil tank 5 to the hydraulic equipment through the oil outlet pipe 8, and then flows back to the inside of the oil tank 5 through the oil return pipe 6. A filter box 7 is installed on the oil return pipe 6, and a filter screen 25 is inserted into the filter box 7 to effectively filter the circulating hydraulic oil. The filter screen 25 is installed at an angle to facilitate the falling of filtered impurities into the collection chamber 23. The filtered impurities can be discharged from the drain port 24. The filter screen 25 is installed by plugging in, which is convenient for cleaning and replacement. This utility model features a filter box 7 installed on the return oil pipe 6 to filter the oil circulating back to the oil tank 5, removing impurities from the circulating oil. A filter screen 25 is inserted into the filter box 7 for easy disassembly, cleaning, and replacement. A collection chamber 23 and a drain port 24 are located below the filter box 7 to facilitate the discharge of filtered impurities. A temperature control box 13 is installed inside the installation box 2, and an S-shaped bending temperature control pipe 16 is installed inside the temperature control box 13. A heating chamber 14 is located at the bottom of the temperature control box 13, and a cooling mechanism 9 is installed inside the installation box 2 to regulate the temperature of the liquid in the temperature control box 13, thereby meeting the temperature control requirements under different environments. The bending structure of the temperature control pipe 16 can extend the circulation time of the oil in the temperature control pipe 16, making the temperature control more thorough.
