Embodiment 1:
As shown in Figure 1, Fig. 1 is a structural representation of the present utility model.
The utility model shaft type three cylinder auto-controlled gas-liquid pumps of connecting promptly are the pneumatic automatic control reciprocating hydraulic pumps of shaft type double-component multi-cylinder footpath control with changed scale.It is mainly by connecting in the interior center axis 31, periphery connects into the middle gas drive automatic control power cylinder 3 of series connection and two ends double-component outward by sealing or semiclosed concentric flange bolt and carries feed liquid cylinder 1 and 2 and form, and it comprises left feed liquid cylinder 1, right feed liquid cylinder 2, middle gas drive automatic control power cylinder 3, axis 31, left joiner 4, a left side is flange 41 with one heart, right joiner 5, right flange 51 with one heart, and the automatic control standard air valve group 6 on the ram, main reversing valve core 61.Automatic control standard air valve group is to cooperate the Xin Te system that is made up of standard air valve spare that finishes voluntarily the control commutation with ram.
Specifically be to be connected by interior center axis 31, periphery is joined the middle gas drive automatic control power cylinder 3 that bolt connects into series connection by concentric flange 41 in a left side and right flange 51 with one heart; Axis 31 left ends of middle gas drive automatic control power cylinder 3 link to each other with left feed liquid cylinder 1 by left joiner 4; Axis 31 right-hand members of middle gas drive automatic control power cylinder 3 link to each other with right feed liquid cylinder 2 by right joiner 5; Middle gas drive automatic control power cylinder 3 is connected with automatic control standard air valve group 6 with plate circuit by connecting pipeline.
Gas-liquid pump described in the utility model does not need power supply, do not need other attached machine electric control yet, as long as connect the source of the gas of enough pressure, the automatic control standard air valve group 6 that gas drive automatic control power cylinder 3 and single channel air inlet are controlled in the middle of just making is reciprocating operation voluntarily, thereby drives left feed liquid cylinder 1 and the left and right directions equivalent output operation separately of right feed liquid cylinder 2.Because axis 31, a left side is flange 41 with one heart, right flange 51 with one heart, left joiner 4 and the operation of right joiner 5 series connection three cylinders, make entire pump remain left and right sides to-and-fro motion stress equalization, load without acceptance of persons, seal ring is difficult for revealing, and is free from environmental pollution, energy-saving and emission-reduction, anti-explosion safety, long service life.In addition, left side feed liquid cylinder 1 and right feed liquid cylinder 2 output flow ratios are accurately adjustable, method is by changing the different cylinder diameter of left feed liquid cylinder 1 and right feed liquid cylinder 2, produce double-component control with changed scale output prescription, for example: left cylinder piston area: right cylinder piston area=5:1 to 1:5 has grade proportion or more.Becoming under the cylinder diameter acquisition different proportion situation, this pump still can be with axis about the 31 two power output terminal bars of middle gas drive ram, drive two material cylinder left side feed liquid cylinders 1 and right feed liquid cylinder 2 maintenance entire pump stress equalizations, operate steadily, thereby reach the output of accurate metering control with changed scale, and can be when left feed liquid cylinder 1 and right feed liquid cylinder 2 delivery outlets turn down or close, promptly at full capacity or during overburdening, this pump still can keep gas-liquid equilibrium of forces load force, the pressurize standby of non-overloading nonoverload ground.
Working principle of the present utility model is as follows:
Principle 1: automatic control selector valve group matches with the intermediate power cylinder, realizes the automatic reverse to-and-fro motion.
As shown in Figure 1, when there is air pressure in middle gas drive automatic control power cylinder 3 left chambeies, it is the P mouth air inlet of automatic control standard air valve group 6, the A mouth is given vent to anger, to middle gas drive automatic control power cylinder 3 left piston chamber air feed, simultaneously also to automatic control standard air valve group 6 left end gas control mouth PA air feed, at this moment, power piston runs to right side buffering pressurizing area to the right always, be that small piston horizontal line face enters the right chamber of right cylinder body, make between the big piston right side and the right cylinder body and form closed airbag, the pit zone promptly is among the figure, boost and buffer deceleration to the right, when being pulse signal, the pressure of big piston right side pressurization gas drives air pressure 30% when above greater than the piston left side, the PB end that has promptly promoted the main reversing valve core 61 of automatic control standard air valve group 6 is shifted to the PA end, like this, the function transposition of the main reversing valve core 61 of automatic control standard air valve group 6, making the main gas of P mouth enter the B mouth gives vent to anger, gas drive automatic control power cylinder 3 piston right sides inflation in the middle of making, finishing commutates left fast moves, the main gas of B mouth is also opened one-way valve to the outspoken speed inflation of the PB of buffering booster cavity and main reversing valve core 61 control simultaneously, finishes overcommutation and moves to left.When middle gas drive automatic control power cylinder 3 pistons run to left end, just repeat right-hand member buffering-supercharging-commutation process, thereby finished the commutation operation that moves in circles.Do not need outer attached other electromechanical control element, and finish the motion that goes round and begins again voluntarily.
Principle 2: about the material cylinder diameter equate under the condition, when pump moves to the left or to the right, two cylinders output equal feed liquid 1:1, and keep exporting reduction of feed volume separately in each cylinder running at any time and stablize constant.
As shown in Figure 1, when left feed liquid cylinder 1 moves to the right, as seen the left end feed check valve is opened by suction, rodless cavity is filled feed liquid, and the feed liquid in the rod chamber is by constantly being pushed away, and the one-way valve of left end discharging is at this moment compressed closure by rod chamber high pressure feed liquid, and this process is exactly that left feed liquid cylinder 1 piston is when moving right a unit distance, piston left side rodless cavity is inhaled into two unit feed liquids, and piston right side rod chamber is extruded a unit feed liquid; Meanwhile, when right feed liquid cylinder 2 moves right, also can regard the return motion left of left feed liquid cylinder 1 as, two unit feed liquids of right feed liquid cylinder 2 piston right side rodless cavities are extruded, simultaneously, compress closed right-hand member feed check valve, open right-hand member discharging one-way valve, unit feed liquid in the rod chamber of right feed liquid cylinder 2 pistons left side is advanced in the high pressure backfill, also outwards exports a unit feed liquid simultaneously.I.e. no matter two material cylinder left lateral or right lateral can both keep the condition of any time and position output equal feed liquid to be: each material cylinder rodless cavity piston area is the twice of rod chamber ring taps area or two rod feed liquid cylinders of using left and right sides ring taps cavity area shown in Figure 3 to equate.
Principle 3: the cylinder diameter that more reloads is regulated output reduction of feed volume ratio, reaches the no-load voltage ratio requirement; And no matter under any ratio situation, all keep material cylinder stress equalization.
Be that left feed liquid cylinder 1 and right feed liquid cylinder 2 cylinder diameters are when unequal, when being the twice of right feed liquid cylinder 2 piston areas as the piston area of left feed liquid cylinder 1, when promptly moving to the right as Fig. 1 pump, left side feed liquid cylinder 1 load is the twice of right feed liquid cylinder 2 loads, be export ratio=left cylinder piston area: right cylinder piston area=2:1, also interchangeable certainly cylinder is transferred than for 5:1 to 1:5 grade proportion or more being arranged more.And this moment is if the loaded work piece pressure of output feed liquid is equal, then left feed liquid cylinder 1 load force is 2, and right feed liquid cylinder 2 load force are 1, at this moment, middle gas drive automatic control power cylinder 3 will automatically pass through power piston axis 31 both sides strut and tie balanced loads, promptly as Fig. 1, when pump moves to the right, load force of axis 31 right-hand member power lever pressurizeds forms two and defeats bar, two load force of axis 31 left end power lever tensions form two power pull bars, but they all can be two power bars with the Pneumatic balancing on the power piston, and level is horizontal does not in addition have the attached power of gravity to influence, so middle gas drive automatic control power cylinder 3 and axis bar 31 do not have the beat operation for the even beaer of full balance always.
