The working principle of electromagnetism a powerful person

Chase after the phylogeny of a powerful person of new moon electromagnetism, so far, domestic and international electromagnetism a powerful person is 3 kinds big from the cent on the principle (namely: Move the type, Tong Xian that divide a pace to guide continuously type) , and the differs to go up with the principle distinction from structure of valve of a powerful person and material is divided again it is 6 branch group (move pace of diaphragm structure, cent to weigh mood of film of a structure, forerunner continuously structure, straight move a piston pace of structure, cent moves piston of piston structure, forerunner continuously. Use principle of type electromagnetism a powerful person continuously: When electrify, force of electromagnetism of electromagnetism coil generation guards a pass shut mention from valve base, valve is opened; When cutting off the power, electromagnetism force disappears, bedspring guards a pass shut press on valve base, valve is shut. Characteristic: In vacuum, negative pressure, 0 when pressing, can work normally, but connect diameter not to exceed 25mm commonly. Distributing to use principle of type electromagnetism a powerful person continuously: It is the principle that one kind is moved continuously and forerunner type photograph integrates, when the entrance and exit did not press difference, after electrify, electromagnetism force mixes forerunner young a powerful person directly advocate a powerful person is shut ordinal mention up, valve is opened. Achieve when the entrance and exit when opening dynamic pressure to differ, after electrify, young a powerful person of electromagnetism force forerunner, advocate pressure of the antrum below a powerful person rises, antrum pressure drops on, use thereby press difference advocate a powerful person is pushed up; When cutting off the power, priority valve uses bedspring power or medium pressure is driven shut, move downward, make valve is shut. Characteristic: Be in 0 when controlling difference or vacuum, maximum pressure can credible action, but power is greater, requirement must horizontal installation. Principle of a powerful person of forerunner type electromagnetism: When electrify, electromagnetism force opens forerunner hole, on antrum room pressure drops quickly, in shut all round form on low press difference high, fluid pressure is driven shut move up, valve is opened; When cutting off the power, bedspring force shuts forerunner aperture, entrance pressure passes bypass aperture rapid antrum room is involving a powerful person all round form below low on tall pressing is poor, fluid pressure is driven shut move downward, close valve. Characteristic: Upper limit of fluid pressure limits is taller, can install arbitrarily (need custom-built) but must satisfy a fluid to press poor condition. CNC Milling
