Abstract
The invention discloses a magnetically-driven fluid pump. An extension chamber with springs coiled outside is utilized as a volume-variable fluid cavity, and electromagnetic force is utilized to drive magnets to be in reciprocating motion to change volume of the fluid cavity so as to realize suction and compression of fluid. A piston is omitted, and the sealing problem of the piston and a piston chamber does not need to be taken into consideration, so that manufacturing cost is lowered, and work pressure is reduced.
Description
One, technical field
The present invention relates to a kind of capacity fluid pump, relate in particular to a kind of fluid pump that utilizes suction that alternating magnetic field produces to change the swept volume of pump.
Two, background technique
At present, the kind of pressure pump is more, as the gear pump in oil hydraulic pump, vane pump, plunger pump etc., the and for example more magnetic drive pump for Korrosionsmedium.Plunger pump is to utilize doing relatively reciprocating motion of piston and cylinder body to make the airtight active chamber generation volume-variation in pump realize the suction of convection cell and the effect of pressure, but because the to-and-fro motion of plunger pump is to change by rotatablely moving, its complex structure, manufacture cost is high, energy consumption and noise ratio are larger, and magneto drive fluid pump relies on the field drives changing, and its stroke and stop can be controlled by magnetic force and program, compact structure, efficiency is higher.
The fluid pump the present invention relates to moves with magneto drive soft magnet, the volume of the active chamber that reduces to be made by elastic caoutchouc, and make swept volume reply former state by the restoring force of spring and elastic caoutchouc, thus realize the suction of convection cell and the effect of pressure.Owing to not using piston, needn't consider the wear-resisting problem of sealing problem and cylinder body, not only reduced cost but also reduced operational noise.
Below the patent of several this respects:
Patent " magnetic linear piston pump " (application number: 200320123284.0) be designed with low-pressure cavity, capacity active chamber and hyperbaric chamber, cylinder body is connected with electromagnetic coil, changes suction and pressure that three pressure in chamber are realized convection cell while moving reciprocatingly with piston.
Patent " moving-magnetic linear compressor " (application number: 200510029391.0) piston and permanent magnet are combined, utilize inside and outside yoke and electromagnetic coil that piston is moved reciprocatingly.
Three, summary of the invention
The present invention proposes a kind of magneto drive fluid pump structure and comprises: upper check valve, support, bumper, upper magnet yoke, flexible chamber, spring, lower yoke, field coil, upper fluid hose, lower fluid hose, lower safety check.The electromagnet that lower yoke and field coil form is fixed on frame bottom, is connected with the alternately electric current of break-make.Flexible top, chamber and upper magnet yoke are fixed together, and upper magnet yoke can move reciprocatingly along support, drive flexible chamber flexible.Flexible chamber is the cylinder with spiral, and outside can be coiled spring just.Spring and flexible chamber simultaneous retractable, increase the elastic force of chamber that stretches.Flexible bottom, chamber and lower yoke are fixed together.Support approaches the plane of upper end, flexible chamber most and posts one deck bumper.Upper fluid hose and lower fluid hose are separately installed with upper check valve and lower safety check.Upper magnet yoke for closely movably to coordinate, makes upper magnet yoke to do volume to-and-fro motion along support with support.Upper magnet yoke and lower yoke adopt soft magnet to make.
The working chamber volume that the present invention utilizes the elastic force of suction, spring and the flexible chamber of upper magnet yoke and below magnet to realize flexible chamber changes, and has exempted piston, avoids inner sealing schedule, has reduced manufacture cost, has reduced operating noise.
Four, accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the front section view of this device.
In figure, the position of marking is respectively: 1, upper check valve; 2, support; 3, bumper; 4, upper magnet yoke; 5, flexible chamber; 6, spring; 7, lower yoke; 8, field coil; 9, upper fluid hose; 10, lower fluid hose; 11, lower safety check.
Five, embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
The soft elastic material of upper check valve 1 and lower safety check 11 use is made, and under the effect of front and back pressure difference, can open and close.Bumper 3 materials are the material of good springiness, antifatigue.The electric current passing in the fixing field coil 8 in support below produces suction to upper magnet yoke 4, and upper magnet yoke 4 is moved down, and drives flexible chamber 5 and spring 6 to dwindle, and fluid is extruded.In field coil 8, electric current disconnects, and suction disappears, and flexible chamber 5 and spring 6 diastoles are risen upper magnet yoke, and fluid is sucked.Upper fluid hose 9 be fixed together with the upper end of flexible chamber 5 and together with move, lower fluid hose 10 is fixed with the lower end of flexible chamber 5.Upper magnet yoke 4 closely movably coordinates and needn't consider sealing requirements with support 2.
