Technical field
The utility model relates to electric motors, is specifically related to the axle that can ensure that motor works under deepwater environment
sealing load bascule.
Background technology
after motor is dived into the deep water (as 2000 meters), extraneous hydraulic pressure forms immense pressure in shaft seal place, and compressing shaft seal, makes it to motor internal generation compressional deformation, until motor internal lubricating oil pressure and extraneous hydraulic balance.If deformation is excessive, then shaft seal damages, and motor cannot operate.When motor runs under water, internal lubrication oil is caused to expand owing to producing amount of heat, and then cause motor internal lubricating oil pressure to be greater than extraneous hydraulic pressure, compressing shaft seal, make it to outside motor generation compressional deformation, and then start shaft seal decompression function, by partial interior lubricating oil discharge motor straight to extraneous hydraulic balance, cause leakage of oil, after motor is out of service, thermal expansion effects disappears, the lubricating oil of having discharged cannot timely supply in deep water situation, then can aggravate the imbalance of extraneous hydraulic pressure and internal pressure, shaft seal is caused to damage, motor cannot operate.Therefore deep-water motor is in the urgent need to a kind of device that bidirection press can be provided to balance.
Summary of the invention
The utility model object is to provide a kind of
deep-water motor shaft seal pressure equaliser, after motor is dived into the deep water, injects lubricating oil by bascule to motor internal, reaches motor shaft sealing place inside and outside pressure balance; After motor runs, bascule noted back by the lubricating oil of thermal expansion, solves Leakage, and then ensures that motor normally runs at deep water.
The purpose of this utility model is achieved through the following technical solutions:
There is provided a kind of
deep-water motor shaft seal pressure equaliser, comprise
motor shaft seals, breathing apparatus guard shield, breathing apparatus regulate capsule, breathing apparatus seal cover, breathing apparatus adjustable cap, breathing apparatus cover plate, external respirator guard shield, external respirator to regulate capsule, external respirator seal cover, external respirator adjustable cap, connecting line etc.
wherein, willbreathing apparatus guard shield, breathing apparatus regulate the assembling of capsule, breathing apparatus seal cover, breathing apparatus adjustable cap, breathing apparatus cover plate and and connecting line
connect, and carry out corresponding static seal.
wherein, willexternal respirator guard shield, external respirator regulate the assembling of capsule, external respirator seal cover, external respirator adjustable cap and and connecting line
connect, and carry out corresponding static seal.
Wherein
,breathing apparatus guard shield, breathing apparatus cover plate, breathing apparatus regulate capsule, breathing apparatus seal cover
between form enclosure space, and carry out two-way liquid communication by connecting line and motor internal.
wherein,breathing apparatus regulates between capsule, breathing apparatus seal cover, breathing apparatus adjustable cap and forms hemi-closure space, by breathing apparatus adjustable cap with extraneous
carry out two-way liquid communication.
Wherein
,external respirator regulates capsule, external respirator seal cover, external respirator adjustable cap
between form enclosure space, and carry out two-way liquid communication by connecting line and motor internal.
wherein,external respirator guard shield, external respirator regulate between capsule, external respirator seal cover and form hemi-closure space, by the gap between external respirator guard shield, external respirator seal cover with extraneous
carry out two-way liquid communication.
the beneficial effects of the utility model are after motor is dived into the deep water, and extraneous water is mainentered by the gap between external respirator guard shield, external respirator seal cover and regulate by external respirator guard shield, external respirator the hemi-closure space formed between capsule, external respirator seal cover, inside extruding external respirator regulates capsule, external respirator is regulated capsule, external respirator seal cover, external respirator adjustable cap
between liquid be pressed into motor internal through connecting line, make the interior ambient pressure of motor shaft sealing place keep balance, avoid shaft seal that deformation breakage occurs due to imbalance of pressure.After motor runs, due to thermal expansion effects, motor internal liquid volume increases, unnecessary liquid can mainly through connecting line press-in bybreathing apparatus guard shield, breathing apparatus cover plate, breathing apparatus regulate capsule, breathing apparatus seal cover
between form enclosure space,inside extruding breathing apparatus regulates capsule, increases space and produces unnecessary liquid to hold because of thermal effect,
make the interior ambient pressure of motor shaft sealing place keep balance, avoid motor internal liquid to discharge through shaft seal.
