Description

Technical Field

[0001] The utility model relates to the technical field of vacuum oiling machines, and more specifically to a vacuum oiling machine. Background Art

[0002] For hydraulic dampers, automobile shock absorbers, brake systems, transformers, and other parts working in a pressure difference environment, if there is air in the internal oil, it will affect the performance of the oil. Therefore, it is necessary to inject oil in an airless and closed environment, and a vacuum oil injection machine is required for oil injection.

[0003] After checking, the disclosure (announcement) number: CN203868655U discloses a vacuum oil injection machine. This technology discloses "including an oil inlet, an oil outlet and a circulation port, a coarse filter is provided on the circulation port, the solenoid valve and the coarse filter are connected to the electric control box, a vacuum gauge and a pressure gauge are installed on the upper part of the electric control box, and a vacuum pump is connected between the vacuum gauge and the oil storage tank" and other technical solutions; it has "a pressure relay is connected to the side of the electric control box, and the vacuum gauge and the pressure gauge are both connected to the oil storage tank. The vacuum oil injection machine has high control accuracy and can achieve layer-by-layer protection during the control process. It also has the advantages of compact structure, small size, and flexibility. The invention has the technical effects of "extremely strong resistance"; although the accuracy of the existing vacuum oiling machine has been improved, the existing vacuum oiling machine is not convenient to operate, and it takes a long time to eliminate the bubbles in the oil, which is inefficient and inconvenient for users to use. The existing patent is a fully automatic vacuum oiling machine, and the patent authorization number is CN219750632U. The vacuum pump evacuates the oil storage tank through a T-tube, which can separate the air dissolved in the oil in the oil storage tank. When the air in the oil is separated to form bubbles, the defoaming valve is started, and the defoaming valve works intermittently to generate intermittent bubbles. The bubbles bring the bubbles generated in the oil to the surface of the oil, which improves the defoaming efficiency and can eliminate the gas in the oil more quickly.

[0004] However, the vacuum pump in patent authorization number CN219750632U gradually extracts the air in the oil storage tank. The user can know the vacuum degree in the oil storage tank through the electronic vacuum meter, and can control the time the oil storage tank maintains a vacuum state and the maximum vacuum value in the oil storage tank by controlling the degree, so that the vacuum state of the utility model can be automatically controlled. After the oil storage tank is in a vacuum state, it is left to stand for a period of time to allow the air in the oil to be discharged, and then it is prepared for oil filling. Since the equipment cost of vacuum oil filling is very high, in order to reduce the cost and realize simple vacuum oil filling, we have proposed a vacuum oil filling machine to solve the above-mentioned problems.
