Specific implementation mode
Such as Fig. 1-2, a kind of plunger type magnetostrictive pump, including the pump housing 1, cylinder 3 and shell 5, cylinder 3 be located at the pump housing 1 with
Between shell 5, the pump housing 1 is fixedly connected with cylinder 3, and cylinder 3 is fixedly connected with shell 5, and the pump housing 1 is internally provided with pump chamber 102, cylinder
Cylinder chamber 302 is equipped in 3, shell 5 is internally provided with inner cavity 502, and pump chamber 102, cylinder chamber 302 and 502 three of inner cavity communicate；
Cylinder 3 is equipped with the plug 4 for cylinder to be connected to or obstruct with inner cavity 502, and one of plug 4 end face is gentle
It is equipped with the first preloading spring 9 between cylinder 3, GMM rod 7 is equipped in inner cavity 502, is connected with coil 8 in GMM rod 7, GMM rod 7 withstands on stifled
On first 4 other end；
It is equipped with plunger 2 in pump chamber 102, the second preloading spring 11 is connected between plunger 2 and the pump housing 1, the pump housing 1 is far from shell
One end of body 5 is equipped with the one-way inlet valve 101 communicated with pump chamber 102 and unidirectional outlet valve 103；
Cylinder chamber 302 is circumscribed with the air admission hole 301 for inputting high pressure gas, and inner cavity 502 is circumscribed with to be gone out with atmosphere
Stomata 501.
The pretension bolt 6 for adjusting 7 position of GMM rod is connected in GMM rod 7, pretension bolt 6 and shell 5 are threadedly coupled.
The adjusting nut 12 for adjusting its pretightning force is connected on second preloading spring 11, adjusting nut 12 and the pump housing 1 are threadedly coupled.
Sealing ring 10 is equipped between 102 side wall of plunger 2 and pump chamber.Specifically, one end of the second preloading spring 11 presses against adjusting nut 12,
The other end presses against plunger 2, and the pretightning force of the second preloading spring 11 can be adjusted by adjusting nut 12.
The course of work：
Such as Fig. 1, when magnetostrictive pump inoperative, 7 no power of GMM rod, plunger 4 is in the first preloading spring 9 and high pressure gas
Under the action of be tightly pressed on shell 5, the power for acting on the high-pressure gas pressure and the second preloading spring 11 on plunger 2 is flat
Weighing apparatus, at this point, the volume of pump chamber 102 is minimum.
Such as Fig. 2, GMM rod 7 is powered and in voltage constantly raised half of work period, GMM rod 7 starts to extend and push away
Dynamic plug 4 moves downward, and plug 4 is detached with shell 5, and gap will be generated between plug 4 and shell 5, enters from air admission hole 301
High pressure gas will be flowed out from venthole 501 by the gap, air pressure in cylinder 3 reduces, and acts on the pressure meeting on plunger 2
Reduce therewith.Under the action of the second preloading spring 11, until plunger 2 can move up to balance, therefore 102 volume of pump chamber increases
Greatly, fluid pressure reduces, and to make one-way inlet valve 101 open, unidirectional outlet valve 103 is closed, and fluid is through single admission
Valve 101 flows into.
When driving voltage commutates, i.e., in half of the work period of driving voltage from high to low, GMM rod 7 starts to shrink at, and blocks up
Until first 4 move up under the collective effect of the first preloading spring 9 and high pressure gas and push down shell 5, cylinder 3 is again at this time
Seal chamber is formed, interior pressure increases sharply, and plunger 2 moves downward under the action of gas pressure, and the volume of pump chamber 102 subtracts
Small, one-way inlet valve 101 is closed, and fluid is flowed out by unidirectional outlet valve 103；When acting on the gas pressure and second on plunger 2
When the dynamic balance of preloading spring 11, magnetostrictive pump returns to normal, and so far completes a working cycles.
It should be appreciated that specific embodiment described above is only used for explaining the utility model, it is not used to limit this reality
With novel.By the utility model the obvious changes or variations extended out of spirit still in the utility model protection
Among range.
