Liquid in second rodless cavity enters the second rod chamber through feed pathway 25 again, by second piston 9 reciprocating motion process
Middle to be pressurized to the liquid in the second rod chamber, to generate high pressure, the liquid after generating high pressure is again through 23 row of liquid outlet
Out, second one-way valve 24 is provided at liquid outlet 23, second one-way valve 24 includes the second steel ball 33, the second positioning sleeve 34, third
Spring 35 and the 4th spring 36,35 one end of third spring, which is supported, is set to end cap, and 35 other end of third spring, which supports, is set to the second positioning sleeve
34,36 one end of the 4th spring, which is supported, is set to the second positioning sleeve 34, and 36 other end of the 4th spring, which supports, is set to the second steel ball 33, the second steel ball
33 offset under the action of the 4th spring 36 with liquid outlet 23 to block liquid outlet 23, liquid through liquid outlet 23 be discharged when,
First push the second steel ball 33 compression third spring 35 mobile, so that liquid outlet 23 is opened, so that liquid is discharged through liquid outlet 23 again,
By the way that the 4th spring 36 is arranged, so that abutting even closer between the second steel ball and liquid outlet 23, liquid reflux, Er Qietong are avoided
Setting pressurization lid 26, supercharging base 27 and pressurized spring 28 are crossed, so that when being pressurized to the liquid in the second rod chamber, second
Liquid in rod chamber may not flow into the second rodless cavity.
As the fluid pressure in the second rod chamber increases, the reciprocating motion speed of first piston 7 also slows down therewith, when the
When active force suffered by fluid pressure and first piston 7 in two rod chambers balances each other, 7 stop motion of first piston, when second
When no matter which kind of reason causes decline, first piston 7 can act again, until in the second rod chamber for fluid pressure in rod chamber
Fluid pressure balance each other with active force suffered by first piston 7, to ensure that the output pressure of liquid outlet 23 is constant, work as pressure
After dynamic balance is established, booster pump is automatically stopped, and without noise, does not consume the energy, more environmentally friendly.
Gas-liquid booster pump in the present invention is filled on tank machine for refrigerant, and liquid is refrigerant in the present embodiment, therefore the
One cylinder barrel 1 and the second cylinder barrel 2 all select to be manufactured with stainless steel and aluminum alloy materials, make product will not be because of humidity and cold media gas
And phenomena such as getting rusty, chemically reacting, and select to make cylinder sealing element at work with wear-resisting, cold-resistant, oil resistant sealing element
Will not be cold because of high-frequency, chemical reaction etc. deforms, is damaged, to guarantee the service life of booster pump.
By adjusting input air pressure, output fluid pressure can accordingly be adjusted the present invention, accomplish variable speed, pass through by
Reversal valve 11 is set in rear cover 4, avoids the placement of external reversal valve 11, so that gas circuit be made directly to carry out work in rear cover 4
Make, works quick stable, and air inlet unidirectionally carries out, and first piston 7 and second piston 9 can be made to move back and forth, behaviour
Facilitate, gas-powered first piston 7 moves, and is not required to additional online lubricating pipe, has saved operating cost, and avoid
Furthermore pollution of the mist of oil to ambient enviroment and the injury to human body are thought by being set at inlet 21 and liquid outlet 23
Method ensure that safety when use so that liquid will not flow back because of high pressure.
The above description is only a preferred embodiment of the present invention, thus it is all according to the configuration described in the scope of the patent application of the present invention,
The equivalent change or modification that feature and principle are done, is included in the scope of the patent application of the present invention.
