AI Technical Summary
In the existing technology, the oil filling process of the high-pressure generator oil tank is not continuous, there is a problem of oil sedimentation, and the oil is easily exposed to the outside air, which makes the oil filling process complicated and the oil quality deteriorates.
Design a vacuum oil injection fixture, including a positioning frame, first and second sealing components, and a connector assembly, to form an internal connection between the oil tank and the vacuum oil filter, realize vacuum internal circulation oil injection, ensure that the oil level in the oil storage tank is higher than the oil inlet and outlet of the oil tank, avoid secondary filling and vacuuming, and isolate the oil from contact with the outside air.
Simplify the oil injection process, improve efficiency, reduce costs, ensure oil quality, and achieve an efficient, fast, and stable oil injection process.
