Description

Technical Field

[0001] This utility model belongs to the technical field of pressure testing machines, and specifically relates to an oil tank structure for a pressure testing machine. Background Technology

[0002] The oil tank of the pressure testing machine is an indispensable key component of the hydraulic system. It is mainly used to hold the hydraulic oil of the hydraulic system and to combine with other components to form a pump station system.

[0003] Current hydraulic systems typically have relatively large oil tanks, primarily for cooling the hydraulic oil. During long-term operation, higher pressures cause the oil temperature to rise faster, reducing system stability and leading to poor control. Therefore, traditional hydraulic systems use relatively large oil tanks and rely on a large volume of oil for natural cooling, which not only takes up significant space but also results in ineffective cooling.

[0004] In view of the above factors, a pressure testing machine oil tank structure is provided. The cooling design of the oil tank does not increase the cooling pipeline, and it can work in a high temperature and high pressure environment for a long time, so that the system can work at a suitable temperature. Utility Model Content

[0005] The purpose of this invention is to provide a pressure testing machine oil tank structure to solve the problems mentioned in the background art.

[0006] The purpose of this utility model is achieved through the following technical solution: a pressure testing machine oil tank structure, including an oil tank and a valve group disposed on the oil tank, the oil tank being detachably connected to a mounting base, and cooling structures being detachably connected to both sides of the oil tank.

[0007] The oil tank is also detachably connected to a temperature detection structure. The cooling structure and the temperature detection structure are electrically connected to a controller, thereby enabling precise control of the oil temperature inside the oil tank.

[0008] Furthermore, the oil tank and the cooling structure are detachably connected by bolts.

[0009] Furthermore, the cooling structure includes a cooling plate and a positioning frame for fixing the cooling plate. The positioning frame is a semi-enclosed structure, and the upper / lower edges of the positioning frame engage with the upper / lower edges of the oil tank.

[0010] Furthermore, the positioning frame includes upper / lower protective frames and a positioning plate disposed between the upper / lower protective frames. The positioning plate has a frame structure and protrudes towards one side of the oil tank.

[0011] Furthermore, a cooling fan is detachably connected to the positioning frame, and the cooling fan is in contact with the end face of the cooling chip.

[0012] Furthermore, the temperature detection structure is a thermocouple structure, the temperature detection structure is detachably connected to the oil tank, and the temperature detection structure extends into the oil tank.

[0013] Furthermore, the cooling chip is a semiconductor cooling chip, and thermally conductive silicone grease is uniformly applied to the contact surface between the semiconductor cooling chip and the oil tank.

[0014] Furthermore, the temperature detection structure is electrically connected to the controller via a connecting line.

[0028] like Figure 1-6 As shown, a pressure testing machine oil tank structure includes an oil tank 1 and a valve group 7 disposed on the oil tank 1. The oil tank 1 is detachably connected to the mounting base 2, and cooling structures 3 are detachably connected to both sides of the oil tank 1.

[0029] The oil tank 1 is also detachably connected to a temperature detection structure 4. The cooling structure 3 and the temperature detection structure 4 are electrically connected to a controller 5. The oil temperature in the oil tank 1 is precisely controlled through the cooling structure 3 and the temperature detection structure 4.

[0030] Compared to traditional hydraulic system oil tanks, the oil tank 1 is one-third or one-half smaller in volume, thus reducing the footprint and facilitating installation. The cooling structure 3 and temperature detection structure 4 on the oil tank 1 enable precise control of the oil temperature inside the tank, which is more efficient than using a large-volume oil tank for natural cooling.

[0031] Among them, controller 5 is a single-chip microcomputer or PLC controller.

[0032] To facilitate disassembly and replacement during use, the oil tank 1 and the cooling structure 3 are connected in a detachable manner by bolts.

[0033] To facilitate external protection of the oil tank and cooling structure 3 during use, the cooling structure 3 includes a cooling plate 3a and a positioning frame 3b for fixing the cooling plate 3a. The positioning frame 3b has a semi-enclosed structure, and the upper / lower edges of the positioning frame 3b engage with the upper / lower edges of the oil tank 1.

[0034] The bottom of the positioning frame 3b is connected to the mounting base 2 by bolts.

[0035] The cooling chip 3a is a semiconductor cooling chip, and thermally conductive silicone grease is evenly applied to the contact surface between the semiconductor cooling chip and the oil tank 1.

[0036] The positioning frame 3b includes upper / lower protective frames 3d and a positioning plate 3e disposed between the upper / lower protective frames 3d. The positioning plate 3e is a frame structure and protrudes to one side of the oil tank 1.

[0037] The positioning frame 3b is bolted to the oil tank 1. The upper / lower protective frame 3d and the positioning plate 3e are set as an integral structure or are connected in a detachable manner, with the detachable connection being a bolted connection.

[0038] The positioning plate 3e has a groove in the middle for accommodating the cooling chip 3a. The cooling chip 3a is embedded in the groove and fixed to the oil tank 1 with bolts. A cooling fan 6 is installed on the surface of the cooling chip 3a. The cooling fan 6 is fixed to both sides of the positioning plate 3e with bolts.

[0039] In order to facilitate the removal of heat generated at the other end of the cooling chip by a cooling fan during use, a cooling fan 6 is detachably connected to the positioning frame 3b, and the cooling fan 6 is in contact with the end face of the cooling chip 3a.

[0040] To facilitate real-time monitoring of the oil temperature in the tank during use, the temperature detection structure 4 is a thermocouple structure. The temperature detection structure 4 is detachably connected to the oil tank 1 and extends into the oil tank 1.

[0041] The temperature detection structure 4 is electrically connected to the controller 5 via a connecting line.

[0042] The oil tank is assembled from welded aluminum plates. The cooling fan is fixed on the semiconductor cooling chip on the side of the oil tank. The valve assembly is installed on the oil tank. Thermocouples are used to detect the temperature of the oil in the tank, and the controller is used to control the oil temperature.

[0043] This utility model is equipped with two sets of cooling structures, which can cool the oil tank in an intermittent or simultaneous manner. It is efficient and fast. The cooling structure uses a semiconductor cooling chip to cool the hydraulic oil in the oil tank. When the hydraulic oil is working, the high-temperature oil will circulate to the oil tank. The temperature of the oil in the oil tank is reduced by the semiconductor cooling chip. At the same time, the cooling fan carries away the heat generated at the other end of the cooling chip.

[0044] This utility model's semiconductor cooling chip is a current-transfer type chip. By controlling the input current, high-precision temperature control can be achieved. Combined with temperature detection thermocouples and control methods, it is easy to achieve precise control of the oil temperature in the oil tank, reaching the optimal state for the hydraulic oil used in the components.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
