Description

Technical Field

[0001] This utility model relates to the field of hydraulic pump stations, and in particular to low-energy hydraulic pump stations. Background Technology

[0002] The main function of a hydraulic pump station is to provide hydraulic power. It converts mechanical energy into hydraulic energy to drive various hydraulic equipment and systems. Hydraulic pump stations are widely used in industry, construction, agriculture, and various mechanical equipment to provide these devices with a stable and efficient hydraulic power source.

[0003] A Chinese patent document (CN201822019775.X) describes a portable hydraulic pump station. The pump station includes a main body with a variable displacement pump inside. An electric motor is located on one upper side of the main body, and an accumulator is located on the other upper side. An air filter is located on one side of the electric motor, and a check valve is located on one side of the variable displacement pump. A manual directional valve is located below the accumulator, and an integrated block is fixedly connected below the manual directional valve. This invention provides a portable hydraulic pump station. The pump station utilizes a combination of a variable displacement pump, an electric motor, an air filter, an accumulator, an integrated block, and valves. The electric motor and variable displacement pump are the power sources, converting mechanical energy into the kinetic energy of hydraulic oil. The integrated block allows for the adjustment of the direction, pressure, and flow rate of the hydraulic oil. Casters are installed at the bottom of the main body, allowing the pump station to be moved to a designated location, thus avoiding wasted manpower and resources.

[0004] However, the above-mentioned patent has certain defects in use. Because the oil level in the oil tank fluctuates greatly during use, the hydraulic pump is prone to sucking in air, which makes the hydraulic pump unable to work stably. When the hydraulic pump cannot work stably, the system pressure fluctuates violently, which in turn affects the energy consumption and stability of the entire hydraulic system.

[0005] To address these issues, a low-energy hydraulic pump station is proposed. Utility Model Content

A second connecting pipe 15 is provided on the end of the solenoid valve 13 away from the hydraulic sensing device 10.

[0030] In this embodiment, the hydraulic station body 1 is equipped with an oil tank 2 for storing hydraulic oil. An inclined plate 3 is located at the bottom of the oil tank 2 to allow the hydraulic oil to flow naturally into an oil storage tank 4. An oil delivery pipe 5 is located within the oil storage tank 4, and two fixing buckles 6 are provided on the oil delivery pipe 5 to secure it to the side wall of the oil tank 2. The oil delivery pipe 5 is positioned above the oil storage tank 4 to ensure smooth hydraulic oil flow. A hydraulic pump 7 is connected to the other end of the oil delivery pipe 5. The hydraulic pump 7 is located at the top of the hydraulic station body 1 and is driven by a motor 8. The top of the hydraulic pump 7 is equipped with an overflow valve 11, and the overflow pipe 12 on one side of the overflow valve 11 extends into the oil tank 2. The output end of the hydraulic pump 7 is connected to the first connecting pipe 9, which extends to the hydraulic sensing device 10. The hydraulic sensing device 10 is equipped with a solenoid valve 13 on one side, and the solenoid valve 13 is located at the bottom of the hydraulic station body 1. When the oil enters the solenoid valve 13 through the hydraulic sensing device 10, the hydraulic sensing device 10 detects the oil pressure. When the pressure exceeds the set value, the overflow valve 11 automatically opens, and the oil flows back to the oil tank 2 through the overflow pipe 12.

[0031] Specifically, a cooling device 16 is provided on one side of the main body of the hydraulic pump 7, and a plurality of connecting brackets 23 are provided on one side of the cooling device 16. The cooling device 16 is connected to the main body of the hydraulic pump 7 through the plurality of connecting brackets 23.

[0032] In this embodiment, a cooling device 16 is fixed on one side of the hydraulic station body 1 by multiple connecting frames 23, so that the hydraulic oil entering the oil tank 2 operates at a constant temperature, further reducing energy consumption and extending the service life of the equipment.

[0033] Specifically, the hydraulic station body 1 has a return oil filter 18 on the top side away from the motor 8, and a return oil pipe 19 is provided at the bottom of the return oil filter 18. The return oil pipe 19 is movably installed in the oil tank 2.

[0034] In this embodiment, the oil return filter 18 is provided with an oil return pipe 19 at the bottom. The oil return pipe 19 extends into the oil tank 2 through a movable connection to ensure that impurities are effectively filtered during the oil return process.

[0035] Specifically, the other end of the second connecting pipe 15 is connected to the top of the cooling device 16, and a third connecting pipe 17 is provided on the side of the top of the cooling device 16 away from the second connecting pipe 15. The third connecting pipe 17 is connected to the oil return filter 18.

[0040] In this embodiment, the oil level gauge displays the oil level in the oil tank 2 in real time, which facilitates operators to monitor the oil level and replenish the oil in a timely manner.

[0041] The principle of this utility model is as follows: First, hydraulic oil is injected into the oil tank 2 through the filling port 20. When the oil level in the oil tank 2 reaches the preset level, the bottom of the oil tank 2 is equipped with an inclined plate 3, which allows the hydraulic oil to flow naturally to the oil storage tank 4. The motor 8 is started to drive the hydraulic pump 7. When the hydraulic pump 7 draws oil from the oil supply pipe 5, the oil is always kept in the oil storage tank 4 to avoid cavitation. Under the action of the hydraulic pump 7, the oil enters the hydraulic sensing device 10 through the first oil supply pipe 5. When the oil enters the solenoid valve 13 through the hydraulic sensing device 10, the hydraulic sensing device 10 detects the oil pressure. When the pressure exceeds the set value, the overflow valve 11 automatically opens, and the oil flows back to the oil tank 2 through the overflow pipe 12. Under the action of the solenoid valve 13, the oil is connected to the external equipment through the connection port 14. The solenoid valve 13 delivers the returned oil to the cooling device 16 through the second connection pipe 15. The cooled oil enters the return oil filter 18 through the third connection pipe 17.
