The operation principle of the present invention is described below：
By taking the right side air pump of opposed type permanent-magnetism electromagnetic air pump as an example：
Magnetic field, this magnetic field are just produced in the middle of electromagnetic core 9 when the electromagnetic wire bag 10 of magnet assembly has electric current to flow through
Push-pull motive force is generated to permanent magnet 6, makes to be assembled into integral magnet sliding block 5, permanent magnet 6, magnet shift position
Sensor 8 and tappet 2 are moved to the right along slide rail 4, while also driving spherical piston 13 to move right, make the sky in right cylinder
Gas is pressurized and discharged by the second air outlet valve 17, simultaneously because the air pressure in right cylinder forces the second intake valve 16 to be closed automatically,
The automatic control power supply of drive control device 22 when the magnet shift position sensor 8 on dynamic magnet sliding block 5 is moved to right to setting position
Reverse current is exported to the reverse power supply of electromagnetic wire bag 10, the magnetic on electromagnetic core 9 is overturn, because dynamic magnet 6 is strong permanent magnetic
Body polarity is constant, forces dynamic magnet sliding block 5, permanent magnet 6, magnet shift position sensor 8 to drive spherical piston opposite with tappet 2
Direction is moved, and the second intake valve 16 of right cylinder is automatically opened up air inlet, the second air outlet valve 17 is closed automatically.It is empty in left cylinder 11
Atmospheric pressure increase opens the first air outlet valve 24 to be vented to escape pipe 21, and the first intake valve 23 is simultaneously closed off.Similarly, when move to left to
Action described above is repeated during sensor settings position, makes intake valve, air outlet valve constantly opens and closes operation, forces air
Endlessly from inlet end by air pump to outlet side, formed and force blast to complete air cleaning or air conveying function.
Left side air pump and right side air pump structure parameter are essentially equal, and left and right is controlled by drive control device 22 when simply working
Start simultaneously, the direction of motion of left side air pump and right side air pump is opposite；Because parameter is basically identical, the shaking force of generation is equal,
In the opposite direction, shaking force cancels each other, and realizes air pump and operates steadily noiseless with shaking.
The present invention has used high strength permanent magnet energy block as a result of Electromechanical Design, power saving about 40%, using pair
Put formula working method noise without friction, four cylinder workings and new dynamic sealing mode blast huge discharge foot, no gas leakage loss, as sky
Gas clearing machine and long pipeline equipment of supplying gas have broad application prospects.
The air cleaner made with this air pump is examined through Shaanxi Province measurement instrument product quality supervision and inspection station, and purification is empty
Gas ability reaches（GMP standards）100 grades.（Both when air pump output end can't check more than PM0.5 dust particle noise low air quantity
43.9dB during 35.5dB high air quantity）.
The present invention slightly changes the acting that can move along a straight line over long distances, substitutes long stroke motor acting such as elevator, and oil carries oil
Machine etc..
