Problems solved by technology

[0003] Therefore, the technical problem to be solved by the present invention is that in the prior art, since the oil suction cavity of the oil pump and the test box are all in a certain degree of vacuum, it is difficult for the oil return pump to withdraw the oil from the current oil frame, resulting in the difference between the amount of oil supplied and the oil returned. The unbalanced quantity leads to the defect that it is difficult for the oil to circulate continuously and stably in a vacuum environment

Embodiment 1

[0047] This embodiment provides an oil source system suitable for a vibration test device in a vacuum environment, such as figure 1 , Figure 3 to Figure 5 As shown, it includes: oil pool part 1, oil storage part 2 and circulation mechanism, oil pool part 1 is set in the sealed cavity of test box 4, the sealed cavity of test box 4 is a vacuum environment, and oil storage part 2 is set in the oil pool Under the part 1, the oil storage part 2 is also arranged in the sealed chamber of the test box 4. The oil pool part 1 has gravitational potential energy relative to the oil storage part 2, and the oil pool part 1 communicates with the oil storage part 2, and the oil pool part 1 The oil can be delivered to the oil storage part 2 under the action of gravity; the circulation mechanism includes an oil tank 31, an air circuit assembly, an oil supply assembly and an oil return assembly. The air circuit assembly is arranged on the oil storage part 2, and the air circuit assembly makes t...

Embodiment 2

[0061] Compared with the oil source system provided in the embodiment 1, the oil source system suitable for the vibration test device provided in this embodiment is that the oil storage part 2 is arranged outside the test box 4, and the air circuit assembly Set on the oil storage part 2, one end of the first air pipe 321 communicates with the sealed chamber of the test box 4, the other end of the first air pipe 321 communicates with the oil storage part 2, one end of the second air pipe 323 communicates with the oil storage part 2, and the second air pipe 323 communicates with the oil storage part 2. The other end of the air pipe 323 communicates with the outside air. As an alternative embodiment, the second connecting pipe 332 can communicate with the air supply part 322. The air supply part 322 is an air pump. One end of the air supply part 322 communicates with the second air pipe 323. The other end of the gas element 322 communicates with a nitrogen source.

Embodiment 3

[0064]This embodiment provides an oil source system suitable for a vibration test device in a vacuum environment. Compared with the one provided in Embodiment 1 or Embodiment 2, the difference exists in that the oil pool part 1 directly passes through the oil return assembly. It communicates with the fuel tank 31, and the gas circuit assembly is arranged outside the fuel tank 31.

[0065] The present embodiment provides an oil source system suitable for a vibration test device in a vacuum environment, which reduces the use of oil storage parts 2, correspondingly reduces costs, and saves materials.

Abstract

The invention discloses an oil source system of a vibration test device suitable for a vacuum environment, the interior of a test box is a vacuum environment, an oil pool piece is located in the test box, the pressure in the oil pool piece is smaller than the external atmospheric pressure, and oil in an oil tank enters the oil pool piece under the action of an oil supply assembly; the gas circuit assembly has a state that the test box is communicated with the oil storage part, that is, when the test box is communicated with the oil storage part, the gas pressure in the oil storage part and the gas pressure in the test box slowly tend to be consistent, and oil in the oil pool part enters the oil storage part under the action of gravity; when the gas path assembly conveys gas into the oil storage piece, the gas pressure in the oil storage piece is increased until the oil return assembly can work normally, oil in the oil storage piece returns to the oil tank through the oil return assembly, and circulation is completed.

Description

technical field [0001] The invention relates to the technical field of hydraulic control, in particular to an oil source system suitable for a vibration test device in a vacuum environment. Background technique [0002] The horizontal vibrating table is a widely used test equipment. In order to improve the effective thrust of the equipment, it is necessary to input high-pressure oil through the oil inlet pipeline between the horizontal platform and the guide rail to meet the best working condition of the guide rail. The input oil will temporarily Stay in the oil retaining frame around the guide rail, and then return to the oil tank through the oil return line. Both the oil inlet line and the oil return line are powered by the oil pump and the motor. Under normal temperature and pressure, the hydraulic circuit formed by the oil supply pump and the oil return pump can meet the working requirements of the general horizontal vibrating table, but the test chamber of the four-comp...
