Introduce working principle of the present invention below:
Right side air pump for opposed type permanent-magnett electromagnetic air pump:
Just in the middle of electromagnetic core 9, magnetic field is produced when the electromagnetic wire bag 10 of magnet assembly has electric current to flow through, this magnetic field creates push-pull Driving force to permanent magnet 6, make the magnet slide block 5 being assembled into one, permanent magnet 6, magnet mobile position sensor 8 and tappet 2 move to the right along slide rail 4, also drive spherical piston 13 to move right simultaneously, air pressurized in right cylinder is discharged by the second gas outlet valve 17, simultaneously because the air pressure in right cylinder forces the second suction valve 16 automatically to be closed, when the magnet mobile position sensor 8 on dynamic magnet slide block 5 move to right to drive controller during desired location 22 automatic control power supply export back current electromagnetic wire bag 10 is oppositely powered, make the magnetic overturn on electromagnetic core 9, because dynamic magnet 6 is that strong permanent magnet polarity is constant, force magnet slide block 5, permanent magnet 6, magnet mobile position sensor 8 and tappet 2 drive spherical piston opposite direction to move, the second suction valve 16 of right cylinder is made automatically to open air inlet, second gas outlet valve 17 cuts out automatically.Left cylinder 11 inner air pressure increases to be made the first gas outlet valve 24 open to be vented to steam outlet pipe 21, and the first suction valve 23 cuts out simultaneously.In like manner, when moving to left to described action above repeating during sensor settings position, make suction valve, gas outlet valve constantly opens and closes operation, force air endlessly from inlet end through air pump to outlet side, formed force blast complete air purification or air conveying function.
Left side air pump is completely equal with right side air pump structure parameter, and just control left and right by drive controller 22 during work and start simultaneously, the moving direction of left side air pump and right side air pump is contrary; Because parameter is basically identical, the shaking force of generation is equal, and direction is contrary, and shaking force cancels each other, and achieves air pump and to operate steadily noiseless and vibrations.
The present invention is owing to have employed Electromechanical Design, employ high strength permanent magnet energy block, power saving about 40%, use opposed type working method friction noise, four cylinder workings and new motive sealing mode blast huge discharge foot, without gas leakage loss, have broad application prospects as air cleaner and the long pipeline equipment of supplying gas.
