Description
Technical field
The utility model relates to a kind of series-parallel module-type flexible hydraulic cylinders.
Background technique
Hydraulic cylinder is to apply extremely wide industrial power element in the world, key zero as powered actuation mechanism
Part, play the role of in hydraulic system it is very big, it is small arrive microelectronic field, greatly to ten thousand tons of press machines, on land, in ocean
Etc. every field have its application.Since hydraulic oil is applied to Hydraulic Field by the U.S. at the beginning of last century, the work of hydraulic cylinder
Medium is mineral hydraulic oil always, and hydraulic oil has lubrication left and right well, this plays very well the hydraulic cylinder of reciprocating motion
Reduction abrasion effect.The characteristics of comprehensive current hydraulic cylinder, has a problem in that 1) using hydraulic oil as medium, hydraulic
Oil has certain pollution, after especially leaking, can contaminated land and water source, the remaining for causing decades even upper century-old is dirty
Dye.Each hydraulic cylinder is a pollution risk source.2) for high-pressure hydraulic cylinder, sealing ring is the key that seal cavity reality high pressure
Original part.The flexible dynamic friction generated of hydraulic stem often damages sealing ring, causes oil liquid leakage, and cylinder pressure, which occurs, to be reduced and not
Workable failure.High hydraulic pressure is also required to that more sealing rings are arranged to ensure that hydraulic oil is sealed in wall, and one
Some sealing ring of denier damages it is necessary to replace, and in addition the service life of sealing ring, causes maintenance period short, safeguards more troublesome.3) hydraulic
The machining accuracy of each components of cylinder is high, especially installs axis outer diameter, hole internal diameter and the groove of sealing ring, surface roughness requirements
Height, or even need grinding machine processing and chromium plating etc., the inner wall of cylinder barrel needs depth Boring machine processing, and concentricity requires height, these height are wanted
It asks and just needs high-precision machining tool and the machine operation person with certain operational capacity, improve processing cost, according to statistics,
It being only machined to originally account for 60% or more of hydraulic cylinder cost, for the hydraulic cylinder bigger for diameter, difficulty of processing is bigger,
Cost is higher.4) hydraulic cylinder is very extensive in land application, but seldom using the application of especially deepwater regions under water, mainly
Or the problem of between the pressure and hydraulic cylinder internal oil sealed pressure generated due to extraneous hydraulic pressure, this is flat in deep sea drilling
The oily development field in the sea such as platform, sub-aqua diving device etc. receive limitation, even if there is application, it is also desirable to which additional pressure related with the depth of water is mended
Device is repaid, the function and benefit of hydraulic cylinder are greatly lowered, but expense increases substantially.5) for the hydraulic cylinder of major diameter, due to
Components are more, and weight is very heavy after assembling, cause the inconvenient type using lifting, installation, maintenance；6) some hydraulic cylinders are using emulsification
As medium, this medium is also based on water and oily and mixes liquid, and easy to oxidize rotten in use, service life is short, and
And price is high, use condition and range receive limitation.7) all hydraulic cylinder is dismantled component process in maintenance and is often resulted in
Oil liquid is omitted, and environment is polluted.
