Description
Technical field
The invention belongs to a kind of hydraulic intensifiers, and in particular to a kind of compact single-acting hydraulic booster.
Background technology
Hydraulic intensifier is different using piston both ends active area and the identical principle of stress size, and hydraulic pressure is put
Low pressure can be increased to 200MPa or more by a kind of big ultrahigh-pressure hydraulic element, hydraulic intensifier.Hydraulic intensifier
Three kinds of single-acting one-stroke booster, single-action reciprocating booster and Double-action reciprocating formula booster can be divided into.Single-acting
For one-stroke booster due to can only be moved to a direction, by travel limit, output flow is limited, can not reach continuous increasing
Pressure, the scope of application are narrow.Single-action reciprocating booster may be implemented continuously to be pressurized, but can only one way supercharging, oil sources utilize
Rate only has half, output flow also limited.Two-way continuous supercharging may be implemented, no in Double-effect reciprocating hydraulic pressure booster
By travel limit, output flow is big, is ideal pressurizing elements.But traditional Double-action reciprocating formula that the country uses at present
Hydraulic intensifier is the continuous commutation by solenoid directional control valve, and control pressurized cylinder moves back and forth continuous output high pressure, complicated,
Volume and weight is huge, it has not been convenient to carry, be difficult to use in terms of inflammable and explosive occasion and portable mechanism.
The Chinese invention patent of Publication No. CN101666339A proposes a kind of hydraulic intensifier, is changed using Stroke Control
The scheme continuously moved to valve and main reversing valve control pressurized cylinder, the program are controlled compared with domestic traditional using solenoid directional control valve
The double-acting supercharger of commutation has innovation, but there is also following disadvantages：
(1) since its return of stroke valve is maintained at two positions using steel ball positioning and chain, pressurized cylinder is controlled to difference
Direction movement, it is complicated, difficulty of processing is big.And steel ball positioning is easy to fail, chain is pulled off, and Stroke Control reversal valve will
In floating position, i.e. pressurized cylinder stop motion, therefore this control mode is unreliable；
(2) after its piston moves to the end in one direction, piston can generate shock with the end cap of respective direction, continue
The continuous noise generated that hits of piston and end cap is very big in high frequency motion, and produces adverse effect to service life.
In conclusion existing hydraulic intensifier can be further improved.
