A kind of specific work process of fully automatic liquid pressurized cylinder of the utility model is as follows：Low-pressure intake 25 is opened,
As shown in Fig. 1, low pressure water is flowed by the ends switch valve with two-position and five-pass P, is only flowed into low pressure water inlet pipe 17 by the ends A, such as attached
Shown in Fig. 3, side is flowed by the high-pressure water pipe interface 13 in left side low pressure chamber 101 in the low pressure chamber 101 of left side, and the other side is successively
Pass through low pressure water supply connector 191, low pressure check valve a20, low pressure check valve b21 and the low pressure water supply connector in six check valves 19
191, low pressure water inlet pipe, high-pressure water pipe interface 13 flow into left side high pressure chest 102 and right side high pressure chest 202, complete first at this time
The injection of secondary low pressure water, due to being each filled with low pressure water in left side low pressure chamber 101, left side high pressure chest 102, right side high pressure chest 202, and
There is no low pressure water in right side low pressure chamber 201, by force analysis it is found that at this time in left side low pressure chamber 101 and left side on left piston 3
The low pressure water effect lower stress balance of high pressure chest 102, and then made by 202 mesolow waterpower of right side high pressure chest in right piston 4
With, it cannot keep balancing, can be gradually mobile to the right, while driving left piston 3 gradually mobile to the right by piston rod 5, then left side
The volume of high pressure chest 102 can be gradually reduced, and due to the length very little of low pressure water inlet pipe 17, and by low pressure check valve b21's
Restriction effect, the volume of water is kept approximately constant in left side high pressure chest 102, therefore the pressure of wherein water constantly increases, when right piston 4
When being moved to contact reversing bar 11, it can start that reversing bar 10 is pushed slowly to move right, and compression reseting spring 12 simultaneously, work as a left side
When fluid pressure in side high pressure chest 102 is more than the setting pressure of high pressure check valve c22, high pressure water passes sequentially through low pressure water inlet pipe
17, high pressure check valve c22, high-pressure outlet 18 flow into energy storage canister 23, and at the same time, right piston 4 is so that reversing bar 10 drives
It is moved right with the switch valve with two-position and five-pass motion bar 30 of its firm welding, to the control on switch valve with two-position and five-pass motion bar 30
Plunger 28 processed moves so that A mouthfuls are sealed, and the low pressure water flowed out by B mouthfuls enters in low pressure water inlet pipe 17, and side passes through right side
High-pressure water pipe interface 13 in low pressure chamber 201 flows into the low pressure chamber 201 of right side, and the other side passes sequentially through in six check valves 19
Low pressure water supply connector 191, low pressure check valve a20, low pressure check valve b21 and low pressure water supply connector 191, low pressure water inlet pipe, high pressure
Waterpipe jointing 13 flows into left side high pressure chest 102 and right side high pressure chest 202, completes the injection of second of low pressure water at this time, due to
It is each filled with low pressure water in right side low pressure chamber 201, right side high pressure chest 202, left side high pressure chest 102, and is not had in a right side low pressure chamber left side 101
There is low pressure water, by force analysis it is found that at this time in the low pressure water of right side low pressure chamber 201 and right side high pressure chest 202 in right piston 4
Lower stress balance is acted on, and is then acted on by 102 mesolow waterpower of left side high pressure chest on left piston 3, cannot keep balancing, meeting
Gradually mobile to the left, while driving right piston 4 gradually mobile to the left by piston rod 5, then the volume of right side high pressure chest 202 can be by
It is decrescence small, and due to the length very little of low pressure water inlet pipe 17, and by the restriction effect of low pressure check valve b21, right side high pressure chest
The volume of water is kept approximately constant in 202, therefore the pressure of wherein water constantly increases, when left piston 3 is moved to contact reversing bar 11
When, it can start that reversing bar 10 is pushed slowly to be moved to the left, and compression reseting spring 12 simultaneously, the liquid in right side high pressure chest 202
When body pressure is more than the setting pressure of high pressure check valve c22, high pressure water pass sequentially through low pressure water inlet pipe 17, high pressure check valve c22,
High-pressure outlet 18 flows into energy storage canister 23, and at the same time, left piston 3 is so that reversing bar 10 drives two with its firm welding
5 way valve motion bar 30 moves downward, to which the control plunger 28 on switch valve with two-position and five-pass motion bar 30 moves,
By recycling above-mentioned two process successively, you can realize the effect of low pressure liquid supercharging.Energy storage is can observe by pressure gauge 24
Fluid pressure in tank 23 can obtain high pressure water by the way that the equipment of high pressure water will be needed to connect high-pressure outlet 26.
It should be noted last that the above specific implementation mode is only to illustrate the technical solution of the utility model rather than limit
System, although the utility model is described in detail with reference to preferred embodiment, it will be understood by those of ordinary skill in the art that,
The technical solution of the utility model can be modified or replaced equivalently, without departing from the essence of technical solutions of the utility model
God and range, should all cover in the right of the utility model.
