Embodiment Construction
[0014] The invention provides a special oil injection device for deep-sea oil pressure compensation equipment, which has a simple structure and an ingenious design. The combined use of a pneumatic check valve and a hydraulic check valve can realize simultaneous vacuuming and oil injection during oil injection, preventing The step-by-step process causes the propeller to leak air. At the same time, the oil storage tank with a special structure can recover the excess oil, which is convenient to use and avoids waste.
[0015] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0016] like figure 1 As shown, a special oil injection device for deep-sea oil pressure compensation equipment includes a propeller 1, an oil injection port 2, a vacuum pump 7, an oil storage barrel 9 and an oil pipe 16, and is charact...

The invention provides an oiling device special for a deep-sea oil pressure compensation device and belongs to the technical field of underwater propeller devices. The oiling device special for the deep-sea oil pressure compensation device comprises a propeller, an oiling port, a vacuum pump, an oil storage barrel and oil pipes and further comprises a first liquid-operated one-way valve, a three-way valve, a second liquid-operated one-way valve, an air-operated one-way valve and a stop valve. One end of the first liquid-operated one-way valve is connected with the oiling port of the propeller through one oil pipe, and the other end of the first liquid-operated one-way valve is connected with one end of the three-way valve. Another one end of the three-way valve is connected with the oil storage barrel through one oil pipe, and another one end of the three-way valve is connected with the second liquid-operated one-way valve through one oil pipe. The other end of the second liquid-operated one-way valve is connected with the air-operated one-way valve. The other end of the air-operated one-way valve is connected with the vacuum pump. The vacuum pump is provided with a pressure gage. The oiling device special for the deep-sea oil pressure compensation device has the beneficial effects that the structure is simple, and the design is ingenious; because the air-operated one-way valve and the liquid-operated one-way valves are cooperatively used, creation of vacuum and oiling can be simultaneously conducted during oiling, and the phenomenon that air leakage happens to the propeller because creation of vacuum and oiling are conducted step by step is avoided; and meanwhile, the oil storage barrel of a special structure is adopted, redundant oil can be recycled, and therefore waste is avoided.
Description
technical field [0001] The invention relates to the technical field of underwater thruster devices, in particular to a special oil injection device for deep sea oil pressure compensation equipment. Background technique [0002] The oil-sealed propeller is a statically sealed propeller, but due to the action of lubricating oil, the friction between the motor shaft and the sealing ring is greatly reduced, and the service life of the propeller is improved. Compared with magnetic coupling and other sealing forms The propeller has the advantages of high transmission efficiency and stable performance. At the same time, because the inside of the shell is filled with liquid, it is not necessary to make the shell very thick, which can offset the extrusion of the shell by the external waters, and is especially suitable for use in deep sea environments. , and the weight is greatly reduced. But for the assembling of oil-seal propeller, lack a kind of simple and effective device at pres...
