Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, high pressure resistant moving-magnetic type proportion electro-magnet of the present invention, comprises push rod 1, drive end bearing bracket 2, housing 3, banking stop 4,9, spring 5, control coil 6, moving permanent magnet 7, flux sleeve 8, quiet permanent magnet 10, magnetism-isolating loop 11, rear end cap 12. Drive end bearing bracket 2, housing 3, flux sleeve 8, rear end cap 12 is made by permeability magnetic material.
Housing 3 is hollow housing, and two ends are connected with drive end bearing bracket 2 and rear end cap 12 respectively, and flux sleeve 8 is connected with the inner side of drive end bearing bracket 2 and the inner side of housing 3, and control coil 6 is set in the cavity of formation, and very high oil liquid pressure can be born in inside. The outer ring surface of quiet permanent magnet 10 directly contacts with the inner ring surface of flux sleeve 8, and the rear end of quiet permanent magnet 10 is fixedly connected with rear end cap 12, between flux sleeve 8 and rear end cap 12, magnetism-isolating loop 11 is set. Moving permanent magnet 7 can freely-movable in the endoporus of flux sleeve 8, contrary with the polarity of quiet permanent magnet 10. One end of push rod 1 is supported in drive end bearing bracket 2, and the other end is fixedly connected with moving permanent magnet 7.
Suck on the end face of drive end bearing bracket 2 or quiet permanent magnet 10 for fear of moving permanent magnet 7, between drive end bearing bracket 2 and moving permanent magnet 7, spring 5 is set, on the end face of drive end bearing bracket 2 and quiet permanent magnet 10, the banking stop that non-magnet material is made is set, thickness is 0.3～0.5mm.
In the time of control coil 6 no power, between moving permanent magnet 7 and quiet permanent magnet 10, because polarity produces repulsion effect relatively, and balance each other with spring force.
As shown in Figures 2 and 3, when control coil 6 passes into after electric current, inwards, control coil 6 produces excitation field to the vertical paper of current direction. Under control coil 6 and moving permanent magnet 7,10 effects of quiet permanent magnet, main magnetic circuit distributes as shown in Figure 2. Φ1And Φ2For the controlling magnetic field of control coil 6 and the 7 actings in conjunction generations of moving permanent magnet, Φ1Form closure along housing 3, flux sleeve 8, moving permanent magnet 7, drive end bearing bracket 2, produce directed force F1；Φ2Leading portion 81, drive end bearing bracket 2 along housing 3, flux sleeve 8, moving permanent magnet 7, flux sleeve 8 form closure, produce directed force F2; The magnetic circuit Φ that quiet permanent magnet 10 produces3Form closure along rear end cap 12, housing 3, fairlead 8, produce directed force F3. Directed force F1、F2And F3With make a concerted effort F action characteristic as shown in Figure 3, F1And F2Be suction, drive moving permanent magnet 7 to left movement, directed force F3For repulsion effect, drive moving permanent magnet 7 to left movement, therefore the power output of electromagnet and proportion control characteristic are all significantly improved.
