Higher pressure is exported, and its specific internal structure does not illustrate here.
As shown in figure 1, the variable pump 2 is the power source of whole device, hydraulic oil is endlessly provided to the device,
It is set to complete necessary operation, the variable pump 2 can select plunger pump, or two-way variable displacement pump, not limit here.It is described
The oil inlet of variable pump 2 is connected with oil groove 1, and the oil inlet of the variable pump 2 can also set filter 16, pass through filter 16
It can be filtered to entering the hydraulic oil in device, so as to protect each equipment in system, extend equipment uses the longevity
Life.
The P mouths and storage of the oil-out of the variable pump 2 oil inlet with the first overflow valve 3, three position four-way directional control valve 4 respectively
The import connection of energy device 5, by setting accumulator 5 to reduce impact of the high-voltage oil liquid to equipment, while the energy stored, makes
Hydraulic fluid pressure is more steady.The oil-out of first overflow valve 3 is connected with oil groove 1, i.e. the first overflow valve 3 its safety valve
Effect, for controlling the output pressure of variable pump 2, compression shock is reduced, ensures the normal operation of the present apparatus.
The T mouths of the three position four-way directional control valve 4 are connected with oil groove 1, A mouths and the hydraulic lock 6 of the three position four-way directional control valve 4
The connection of E mouths, the B mouths of the three position four-way directional control valve 4 be connecteds with the F mouths of hydraulic lock 6, the E1 mouths of the hydraulic lock 6 and are pressurized
The low pressure chamber connection of device 7, the F1 mouths of the hydraulic lock 6 are connected with the rod chamber of booster 7.The hydraulic lock 6 includes two
Hydraulic control one-way valve, it act as interlocking, so as to ensure that the piston rod in booster 7 is in stable state, the hydraulic lock 6 all the time
For the known technology of those skilled in the art, simple elaboration only is done to its structure here.
Because during experiment, experiment inherently causes certain leakage with medium, so the present apparatus is additionally provided with moisturizing
Pump 9, the import of the small pump 9 are connected with tank 8, and the import exported all the way with the second overflow valve 11 of the small pump 9 connects
Connecing, another way is connected with the import of check valve 10, and the outlet of second overflow valve 11 is connected with tank 8, and similarly described second
Overflow valve 11 also does safety valve use, and its pressure set points is decided in its sole discretion according to test situation.

Operation principle of the present invention is：Pressure test process is divided into pressurization stages, packing stage and pressure release stage, on-test
When, manual relief valve 12 is first shut off, the high pressure chest of booster 7 and tested gas cylinder 14 is full of water by small pump 9.Again
Start variable pump 2, in pressurization stages, three position four-way directional control valve 4 is in left station, the hydraulic oil that now variable pump 2 exports
Piston rod is promoted to move right into the low pressure chamber of booster 7, while the hydraulic oil in the rod chamber of booster 7 passes through hydraulic pressure
Returned to after lock 6 and three position four-way directional control valve 4 in oil groove 1, due to being provided with check valve 10, now in the high pressure chest of booster 7
Water will be entered in multiple tested gas cylinders 14, completed to being pressurized while multiple tested gas cylinder 14, when pressure reaches
During to test value, three position four-way directional control valve 4 is located at intermediate stations, so as to which tested gas cylinder 14 is in packing state, due to
Hydraulic lock 6 is provided with, piston rod in booster 7 can be made to remain static, so that the pressure in tested gas cylinder 14 begins
Stable state is in eventually, bust will not occur or the situation that jumps, packing stage are the voltage-withstand test of tested gas cylinder, work as guarantor
After pressing time arrival, three position four-way directional control valve 4 is in right working position, and the hydraulic oil that now variable pump 2 exports enters booster 7
Promote piston rod to be moved to the left in rod chamber, complete pressure release so as to the high pressure chest of booster 7, so complete to being tested high pressure
The pressure test of gas cylinder 14.After the completion of experiment, by opening the manual pressure release of relief valve 12, tested gas cylinder 14 is removed i.e.
Can, simple operation is simple in construction.
