Embodiment
Accompanying drawing is embodiment of the present utility model
Below in conjunction with accompanying drawing summary of the invention of the present utility model is described further
With reference to Fig. 1, shown in Figure 2, comprise cylinder body and piston, it is characterized in that, an end that also comprises piston/cylinder 9 is connected with changeover valve core 3, the other end is connected with plunger cylinder 11, at piston/cylinder 9, plunger cylinder 11, a connecting rod 7 is arranged in the interior air chamber of changeover valve core 3, one end of described connecting rod 7 passes the spring of installing in changeover valve core 3 inner chambers 4 and is connected with nut 5, the other end of its described connecting rod 7 is connected with plunger 10, be connected with piston 8 on the plunger 10, the both sides of piston 8 are provided with air chamber I and air chamber III, inner chamber at plunger cylinder 11 is provided with air chamber IV, simultaneously, be connected with fluid one-way valve 12 on this cylinder body and go into liquid one-way valve 13, one-way valve 12, be connected with pressure spring on 13, fluid one-way valve 12 and go into liquid one-way valve 13 successively with Drainage pipe 14, liquid-in pipe road 15 1 ends connect, air chamber is connected with changeover valve core 3 in piston/cylinder 9 right-hand members, be connected with on the external diameter of piston/cylinder 9 into tracheae 1 and outlet pipe 2, interior air chamber right-hand member is provided with air chamber II, be connected with locating stud 6 on the described changeover valve core 3, connecting pipe (16) two ends are connected on the air chamber (III) of air chamber (V) on the changeover valve core (3) and piston/cylinder (9), and the corrugated loop curve of said changeover valve core 3 outer rims and ring-shaped air chamber (V) constitute air distributing device.
Shown in Figure 3, be connected with three locating studs 6 on the changeover valve core 3, on each locating stud 6 pressure spring is installed all.
In sum, working principle of the present utility model and structure are as follows: this model utility provides a kind of industrial pump.It is made up of fluid power plunger, charged piston, control changement, gas distribution channels, dosing passage.Fluid power plunger 10 is plunger pumps, can realize high pressure.Be furnished with and suck and extrude one- way valve 13,12 formation dosing passages.The to-and-fro motion of plunger 10 air chamber in fluid cylinder makes the volume space of air chamber in the fluid cylinder ascending, and the continuous cycle of descending again formation changes, and just finishes the suction-pressure-suction-pressure work cycle of pump under the cooperation of dosing passage.Movement process is: when plunger 10 air chamber in fluid cylinder was extracted out, interior air chamber formed negative pressure gradually, and no-pressure liquid by the dosing pipeline under the atmospheric pressure effect, be drawn into the interior air chamber of fluid cylinder.And in plunger 10 inserts fluid cylinders during air chamber, gas chamber volume diminishes in the fluid cylinder, makes the interior fluid pressure of fluid cylinder increase, and when pressure reached the set pressure of discharge opeing one-way valve 12, liquid just extruded from fluid cylinder.Charged piston 8 is designs that enough power is provided for plunger 10 motions.It is made up of big piston 8, plunger 10, connecting rod 7.Piston 8 diameters depend on the output set pressure of plunger 10 diameters and plunger pump.The to-and-fro motion of piston 8 drives plunger 10 and moves reciprocatingly.
In Fig. 1 position: gas enters the right air chamber I and the air chamber II of cylinder body 9 by gas feeding pipe 1, promotes piston 8 to left movement.Gas among the piston 8 left air chamber III is discharged through outlet pipe 2 through entering the belt air chamber V on the changeover valve core 3 connecting tube 16 again.At this moment, plunger 10 is also to left movement.Because air chamber IV volume diminishes in the entering of plunger 10, plunger case, make that fluid pressure increases in the air chamber, when pressure reached set pressure greater than one-way valve 12, liquid backed down one-way valve 12 and extrudes the air chamber in plunger case.Simultaneously, in said process,, drive spring 4 to left movement by connecting rod 7 and nut 5.Because locating stud 6 locatees spool 3 for a position in the drawings, spool does not move for 3 this moments, and makes the length of spring compressed stored energy.When piston 8 moves to when making spring 4 energy stored be enough to overcome the clamping force of spring holder 6, spool 3 can be suddenly to left movement under the effect of spring force, and spring energy is released, the b position that locating stud 6 is aimed among the figure, as shown in Figure 2.At this moment, the belt air chamber V of the gas stream of gas feeding pipe 1 on spool 3 via connecting tube 16 arriving piston 8 left air chamber III, acts on the left end of piston 8, promotes piston 8 and moves right, and just realized the commutation of piston 8.At this moment, plunger 10 moves right with piston 8, makes air chamber IV volume expansion in the plunger cylinder, produces negative pressure; And go into liquid under the atmospheric pressure effect, and by opening one-way valve 13 in liquid-in pipe road 15, enter plunger cylinder air chamber IV, finish the suction process of liquid.At this moment, the gas of piston 8 back pressure air chamber I communicates with air chamber II by the slit in the middle of the changeover valve core 3, discharges by outlet pipe 2 again.When piston moved right, the boss on the connecting rod 7 promoted spring 4 and moves right, because the drag effect of locating stud 6, spool 3 is motionless during beginning, and spring 4 is compressed energy-storage just.When energy storage reaches when being enough to overcome the resistance of locating stud 6, spool 3 will overcome the location resistance suddenly and move right under the effect of spring force, the center of locating stud 6 and groove a position are aligned, and at this moment, blowhole communicates with air chamber I, gets back to state shown in Figure 1 again.This has just finished the work cycle of a pressure-suction.
As long as the gas that this device is gone in tracheae 1 and the outlet pipe 2 has pressure reduction, can realize the reciprocating type topping-up pump proper functioning that spring energy-storage commutation air pressure drives.Motor and power supply for this reason, do not adopt topping-up pump of the present utility model economical and practical, can save energy the source, reduce cost.
