The structure of above-mentioned pressure compensator 200 as shown in figure 3,
The pressure compensator 200 includes：It inside sets the cylinder of compensation cavity and is placed in the piston 203 of inner barrel.Wherein mend
It repays cavity and two parts is divided by piston：Inner cavity 201 and exocoel 202.Filled with insulation hydraulic oil, exocoel 202 wherein in inner cavity 201
Full of seawater.
Logical hydraulic fluid port 204 is provided on pressure compensator 200；Logical 204 one end of hydraulic fluid port is communicated with inner cavity 201, the other end and
The cylinder barrel of servo electric jar, spring bearing, the gear-box of the retarder of servomotor and power train communicate, so that insulation hydraulic oil
At these positions.Petroleum pipeline can also be fixed at logical 204 position of hydraulic fluid port makes the inner cavity 201 of pressure compensator and servo electricity
The inner cavity of cylinder of dynamic cylinder 100, spring bearing, servomotor retarder with and the gear-box of power train be connected.
With the work of servo electric jar, the liquid dielectric that is full of inside the cylinder barrel and gear-box of servo electric jar 100
Fluid can gradually decrease, so the oil pressure of servo electric jar 100 can be reduced at leisure.Pressure in pressure compensator inner cavity 201
The pressure of pressure compensator exocoel 202, the movement of the piston of pressure compensator under seawater pressure effect, until pressure can be less than
The oil pressure of compensator inner cavity 201 reaches balance with the hydraulic pressure of exocoel 202.

With unloading port 206.Repairing mouth 205 is located at the top of inner cavity 201, and is communicated with inner cavity 201.Unloading port 206 is located at inner cavity 201
Bottom, and communicated with inner cavity 201.Blocking is both provided in repairing mouth 205 and unloading port 206.In installation and transportation pressure compensator
It is not oil-filled when 200, in the filling and sealing into progress fluid before the work of seabed.
When the servo electric jar of the utility model works at deep-sea, cylinder barrel outside and push-rod assembly are in servo electric jar
The part contacted directly with seawater.Since seawater has certain corrosivity, it is necessary to carry out a series of anti-corrosion to these places
Measure.Specifically use following measure：
The cylinder barrel 3 and push rod housing 9 of above-mentioned servo electric jar are made of aluminum alloy materials.
In the outside of the cylinder barrel 3 of servo electric jar and the surface protective mulch of push rod housing 9, can also protect herein
Cathodic protection is further used on the basis of layer.The anticorrosion with painting coating such as on the push rod of the outside of cylinder barrel and push-rod assembly
(the new 3LPE anticorrosion coating on pipeline of 3LPP corrosion-inhibiting coatings, Tao Shi, high-performance composite coating (HPCC) etc.).For push rod housing 9,
Since it is prolonged in movement and Frotteurism, it is highly preferred that the corrosion-inhibiting coating sprayed on push rod housing 9 selects wearability
Anti-corrosion material, such as epoxies anti-corrosion material.
For the sealing problem at deep-sea, as a result of pressure compensator, servo electric jar is balanced to a certain extent
The pressure of structure inside and outside largely reduces the sealing difficulty of structure.However, it is needed due to existing in pressure compensator
Push rod housing 9 when being acted with the piston 203 of seawater pressure change location and servo electric jar execution.Piston 203 need with
Seawater and pressure compensator inner barrel contact back and forth；And push rod housing 9 needs the cylinder barrel 3 with seawater and servo electric jar
Inside is contacted back and forth.Especially push rod housing 9, almost all and contact with sea water when stretching out, again can be complete when shrinking
Inside cylinder barrel 3 in servo electric jar.This is a very big challenge for sealing, is a kind of Deep Sea Dynamic Sealing.This reality
Outside 10 inside of cylinder barrel Supporting cover and piston 203 sealing element is set to be sealed with new, which uses high-performance
The O-shaped rubber ring of rubber compression molding, this kind of rubber have good wear-resisting and dynamic sealing performance.
From the above, it is seen that the utility model realizes the high-precision control of power, position, speed using servomotor driving
System, is balanced seawater pressure using pressure compensator, and deep-sea anti-corrosion and sealing etc. are realized by a series of technological means
Wen Di, to meet its deep-sea operating condition.The servo electric jar can be used for the special linear drives occasion such as deep-sea, have very high
Output accuracy and efficiency, can to movement accurately control.
Although the utility model has been described by way of example and in terms of the preferred embodiments, embodiment does not limit the utility model.Not
In the spirit and scope for departing from the utility model, any equivalence changes done or retouching also belong to the guarantor of the utility model
Protect scope.Therefore the scope of protection of the utility model should be using the content that claims hereof is defined as standard.
