Description
Technical field
The present invention relates to a kind of booster, a kind of especially Double-action reciprocating formula liquid that reliably can be automatically continuously pressurized
Pressure 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.
Notification number is that the hydraulic intensifier patent of invention of CN101666339A proposes a kind of utilization Stroke Control reversal valve
The scheme continuously moved with main reversing valve control pressurized cylinder, the program are commutated compared with domestic traditional using solenoid directional control valve control
Double-acting supercharger there is 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) complicated integral structure, high processing costs.

Damping hole 8.1, right cavity 7.2 is interior to have the right damping hole 8.2 for being connected to right cavity 7.2 and right control chamber 6b.
The work that following is a brief introduction of a kind of Double-effect reciprocating hydraulic pressure booster according to the ... of the embodiment of the present invention is former
Reason:
Oil inlet P can be connected with hydraulic pump outlet when practical application, oil return inlet T is connected with fuel tank, high-pressure oil outlet H
It is connected with operating cylinder or other executive components.
Reversing valve core 7, left spring 9.1, right spring 9.2 have collectively constituted automatic reverse valve module.This automatic reverse valve group
Part can according between oil inlet P and the second actuator port B pressure difference and the second actuator port B and oil return inlet T between pressure
Difference carries out left and right sliding switching oil circuit, and then controls piston 2 and drive left plunger 3.1,3.2 bilateral reciprocation of right plunger to carry out
Supercharging.
Before oil inlet P oil inlet, spool 7 is set to be in as shown in Figure 1 by the active force of left spring 9.1, right spring 9.2
Initial position, the second through flow hole 7b are communicated with oil inlet P, and third through flow hole 7C is communicated with oil return inlet T.
When oil inlet P oil inlet, fluid enters right control chamber 6b, left control chamber through the second through flow hole 7b, right damping hole 8.2
The fluid of 6a flows into the second actuator port B by the first damping hole 8.1, the first through flow hole 7a, reversing valve core 7 in oil inlet P and
Start to be moved to the left (at this point, left spring 9.1 is compressed, right spring 9.2 is stretched), third under the pressure difference of second actuator port B
Through flow hole 7c gradually separates with oil return inlet T and the second through flow hole 7b is connected to oil inlet P, causes the pressure of right control chamber 6b more next
Higher final and oil inlet P pressure is equal, oil inlet P and the second actuator port B phases when reversing valve core 7 moves to left position
Logical, the first actuator port A is communicated with oil return inlet T, and fluid enters right piston chamber 2b, piston by oil inlet P through the second actuator port B
2 start to be moved to the left, and the fluid of left piston chamber 2a flows back to fuel tank through the first actuator port A, oil return inlet T.The oil of oil inlet P simultaneously
High pressure is discharged to by third check valve 5.1 after fluid supercharging of the liquid through the second check valve 4.2 entrance right plunger chamber 6d, left plunger cavity 6c
Oil outlet H.
After piston 2 moves downward to the end, fluid no longer flows.Pressure difference between oil inlet P and the second actuator port B disappears
Lose, reversing valve core 7 left spring 9.1 (left spring 9.1 push away to the right to restore), right spring 9.2 (spring 9.2 draw to the right with
Restore) active force start to move right, and during moving right, third through flow hole 7c is connected to oil return inlet T to be made
The pressure of right control chamber 6b is less than the pressure of left control chamber 6a, and reversing valve core 7 continues to be shifted to the right to right end position, and second is through-flow at this time
Hole 7b separates with oil inlet P and third through flow hole 7c is connected to oil return inlet T, and right control chamber 6b is equal with oil return inlet T pressure, oil inlet
P is communicated mouth with the first actuator port A, the second actuator port B is communicated with oil return inlet T, between the second actuator port B and oil return inlet T
Pressure difference so that reversing valve core 7 is maintained at right end position, fluid enters left piston chamber 2a by oil inlet P through the first actuator port A, living
Plug 2 starts to move right, and the fluid of right piston chamber 2b flows back to fuel tank through the second actuator port B, oil return inlet T, while oil inlet P
Fluid enters left plunger cavity 6c through the first check valve 4.1, and height is discharged to by the 4th check valve 5.2 after the fluid supercharging of right plunger chamber 6d
Extrude hydraulic fluid port H.
After piston 2 moves right to the end, the pressure difference that fluid no longer flows between the second actuator port B and oil return inlet T disappears
It loses, reversing valve core 7 starts to be moved to the left to initial position above-mentioned in the active force of left spring 9.1, right spring 9.2, so far shape
At cycle, piston 2 automatically moves back and forth supercharging back and forth under the control of the present invention, without automatically controlled control.
A kind of Double-effect reciprocating hydraulic pressure booster according to the ... of the embodiment of the present invention, simple in structure, volume compact are processed into
This is low, automatic reciprocating can be pressurized, and is not necessarily to automatically controlled control.
