Constant-temperature hydraulic station

[0018] The present invention will be further described below in conjunction with accompanying drawing:

[0019] Refer to attached figure 1 And attached figure 2 , the present invention provides a constant temperature hydraulic station, including a fuel tank 11 and a cooling assembly filled with antifreeze, the cooling assembly includes a finned radiator 20, a cooling pump 31 and an air cooler 40, the finned radiator 20 is arranged in the middle of the oil tank 11, The cooling pump 31 and the air cooler 40 are provided outside the oil tank 11 .

[0020] The air cooler 40 includes an annular water chamber 41 and a fan 42. The annular water chamber 41 is arranged behind the fan 42. A water chamber water inlet 43 is arranged on one side of the annular water chamber 41, and a water chamber water outlet 44 is arranged on the other side.

[0021] The fin radiator 20 comprises a first bracket 21 and a second bracket 22 and a plurality of finned heat pipes 23, the finned heat pipes 23 are connected between the first bracket 21 and the second bracket 22, and the first bracket 21 is provided with a cooling The radiator water inlet 24, the second bracket 22 is provided with the radiator water outlet 25, the antifreeze liquid outlet pipeline 32 is arranged between the radiator water outlet 25 and the water chamber water inlet 43, the water chamber water outlet 44 and the radiator water inlet An antifreeze liquid inlet pipeline 33 is arranged between 24, and a cooling pump 31 is arranged in the antifreeze liquid outlet pipeline 32.

[0022] Antifreeze is used as the cooling circulation medium. First, the finned radiator 20 can fully exchange heat between the high-temperature hydraulic oil and the low-temperature antifreeze. The cooling pump 31 provides circulation power for the antifreeze in the heat dissipation assembly. The cooling surface area of ​​the antifreeze is large, so that the heat stays on the shell of the annular water chamber 41, and the fan 42 takes away the temperature of the annular water chamber 41, thereby reducing the temperature of the antifreeze. The low-temperature antifreeze enters through the antifreeze inlet pipeline 33 The fin radiator 20 performs heat exchange on the hydraulic oil. The cooling efficiency of this device is much higher than that of the existing conventional hydraulic station, and the temperature of the hydraulic oil is controlled between 50°C and 55°C, thereby preventing the aging of the sealing ring and reducing the cost of the host equipment. Reduce maintenance costs, stabilize power performance, prevent high-temperature emulsification of hydraulic oil, prolong the service life of hydraulic oil, and reduce the amount of hydraulic oil used.

[0023] In this embodiment, a support plate 12 is fixedly connected to the side of the fuel tank 11 , and the air cooler 40 is fixedly connected to the upper surface of the support plate 12 , thereby stabilizing the air cooler 40 .

[0024] In this embodiment, the cooling pump 31 is fixedly connected to the upper surface of the oil tank 11 to make reasonable use of the existing space.

[0025] In this embodiment, a motor 51 is fixedly connected to the top of the oil tank 11, an oil pump 52 is fixedly connected to the end of the motor 51, an oil suction pipe 53 leading to the oil tank 11 is connected below the oil pump 52, and an oil outlet pipe 54 is connected above the oil pump 52. The side is connected with an oil discharge pipe 55 leading to the oil tank 11 , and the oil discharge pipe 55 prevents hydraulic oil from accumulating in the oil pump 52 .

[0026] In this embodiment, a reversing valve 56 is connected to the oil outlet pipe 54, and the reversing valve 56 is connected to an oil return pipe 57 leading to the oil tank 11. The hydraulic oil in the oil outlet pipe 54 can be guided back to the oil tank 11 through the reversing valve 56. middle.

[0027] In this embodiment, support frames 13 are fixedly connected to both sides of the bottom of the fuel tank 11, and the support frames 13 can support the weight of the entire device.

[0028] In this embodiment, an oil level gauge 14 is provided on the side of the fuel tank 11, and an air filter 15 connected to the fuel tank 11 is provided above the fuel tank 11. The air filter 15 can filter the air in the fuel tank 11 to provide hydraulic oil. good workspace.
