Further, as shown in Figure 2,3, the layering regulator be piston, piston include cylinder 2, piston rod 1,
Connecting hole 3；Piston rod moves back and forth in cylinder, and piston is connected to by the space between connecting hole and adjacent two layers spherical shell, living
The cavity 4 and connecting hole 3 that the first end and cylinder of stopper rod surround are connected, the second end and contact with sea water of piston rod, according to seawater
Depth adjusts the pressure in the space between adjacent two layers spherical shell.Weight in this way without additionaling power equipment without increasing submersible
Amount, can pressure between self-control adjacent two layers spherical shell, save time cost and human cost, reliability be higher.
Further, the hydraulic oil is L-HV46 hydraulic oil.
The classification of hydraulic oil is given below.
Hydraulic oil in hydraulic gear primarily serves the effect of transmitting pressure, and the key property of hydraulic oil is by relatively close
Degree, viscosity and its viscosity index (VI), cryogenic property, etc.,
A. the standard criterion of hydraulic oil:
GB 11118.1-2011Hydraulic fluids of L-HL,L-HM,L-HV,L-HS and L-HG type
Hydraulic oil label are as follows:
B. pressing force and temperature classifications:
The working range of hydraulic oil
C. composition or function classification are pressed
| ISO classification | Function | Oily name |
| HH | Mineral lubricating oil without additive | Machinery oil, neutral oil |
| HL | The mineral lubricating oil of antirust antioxygenic property | Universal machine tool lubrication oil |
| HM | The wear-resistant mineral lubricating oil of antirust antioxygen | Antiwear hydraulic oil |

| HS | Antirust antioxygen is wear-resistant, adds tackifier synthetic hydrocarbon oil | Synthesize hydrocarbon low temperature hydraulic oil |
| It is other | The different emulsion of water content |
Divide according to ISO6743/4, hydraulic oil is divided into two major classes: one kind is that the mineral oil origin of fire-resistant (or fire retardant) is hydraulic
Oil, such as HH, HL, HM, HR, HV, HG.Another kind of is inflammable hydro carbons hydraulic oil (mineral oils and synthesis hydrocarbon type).
Further, the low temperature hydraulic oil controls its pressure by hydraulic device, and the hydraulic device includes hydraulic
Motor, throttle valve.The flow of hydraulic oil is controlled by hydraulic motor, throttle valve, to control its pressure.
Further comprising off gas system, water scavenging system, injection system；Hydraulic oil goes degasification by off gas system
Bubble separates water by water scavenging system, and hydraulic oil is injected to the space between shell and inner casing by injection system.
Further, the off gas system is vacuum oil-filter.Vacuum oil-filter oil conditioner, which at home and abroad has, to be compared
Mature product, such as lube purification equipment of great Sheng company of Japan, and the vacuum oil filtering equipment of Dong Zhu company of the country, is suitable for
Power industry and electric appliances plant, paper mill, electrochemical factory, industrial and mining enterprises transformer oil, steam turbine oil (turbine oil), lubrication
Oil, demulsification, degasification, removal of impurities, drainage purification and the waste oil regeneration of the iundustrial oils such as hydraulic oil.One vacuum oil-filter mainly by
Oil inlet filtration system, vacuum-pumping system go out oil filtration system composition.Oil liquid is carried out earlier filtering by oil inlet filtration system；
Vacuum-pumping system will be evacuated negative pressure (generally or lower) in vacuum tank, enable in oil liquid moisture compared under low-temperature condition
Volatilization, the water vapour of extraction is through cooler and water segregator condensation, precipitation；Oil filtration system major function is by oil liquid from vacuum out
It extracts out in tank, then is returned in work box (tank) after multiple fine filters.
Further, the water scavenging system is vaccum dewatering device.This technology original different from oily boiling point using water
Reason, can remove effectively stateful water.The temperature that vaccum dewatering equipment is increased to by oil temperature, and generate about true
Sky, while oil being spread and generates very big surface area effectively to make the water boiling in oil and be evaporated.This device exists
It also can remove some other pollutants easily to gasify while removing water, while there is also the risk of additive gasification loss,
Therefore the denaturation for wanting strict temperature control that base oil and addition is avoided to carve.
Further, the injection system includes vacuum oil unit and high-pressure injection unit；Vacuum oil unit is first
Space between shell and inner casing is vacuumized, air residual therein is reduced, then in the space between shell and inner casing
Fluid pressure line between the two is connected after portion's vacuum degree is identical as vacuum degree in vacuum tank, then to the space between shell and inner casing
Continue to vacuumize, purified hydraulic oil is slowly slowly injected into shell from the lower end to oiling hydraulic device using pressure difference
(process can control hydraulic oil and in oiling hydraulic device to avoid the disturbance of hydraulic oil to space interior between inner casing
The contact area of residual air, effectively reduces secondary pollution)；High-pressure injection unit carries out the space between shell and inner casing high
Pressure injection oil, so that internal pressure is greater than an extraneous atmospheric pressure, (by taking holmium diaphragm pressure compensator as an example, high-pressure injection can be further
Reduce the stereomutation amount of deep-sea hydraulic device hydraulic oil when in use, guarantee pressure compensator deep-sea using when have it is enough
Amount of redundancy).
The above is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form, it is all according to
According to technical spirit any simple modification, equivalent change and modification to the above embodiments of the invention, still belong to the present invention
The protection scope of technical solution.
