Application of the principle of permanent magnet sucker is the continuity of the principle of superposition principle of flux and magnetic field design, circuit design permanent magnet sucker into a plurality of magnetic system, by the relative movement of the magnetic system, to achieve the work surface magnetic field strength of the phase add constructively or destructively, so as to achieve the purpose of holding and unloading. It works as shown in a, when the pole permanent magnet sucker in FIG. (A) status, the magnetic field lines from the magnet pole N, permanent lifting stock, through the yoke, through ferromagnetic workpieces, then back to the magnetic S pole of the magnet yoke enter. Thus, the workpiece can be firmly sucked pole permanent magnet sucker work surface. When the magnetic pole in Figure (b) state, the magnetic field lines of work less than the pole face of permanent magnet sucker, permanent magnetic chuck in the internal composition of a closed loop magnetic circuit, little magnetic field lines from the pole faces of permanent magnet sucker out of work, the permanent jack the price, so the workpiece does not produce suction, can successfully achieve unloaded. Magnetic suspension, also known as (permanent lifting), mainly used for lifting operation process, moving iron, bulk and piece cylindrical magnetic material used widely used in factories, Jilin permanent lifting, dock , warehouses and transportation industries. Press unloading way into YC1 magnetic crane, YC2 magnetic crane, YC3 magnetic suspension and magnetic crane YC4 four types, the most common is the PML's magnetic crane, high multiples of their security, is a permanent sucker magnetic suspension Usage: 1. When lifting, first lifted to the surface clean, if rust should clean the skin and spurs. Coincides with the center line of suckers best focus line, then the suction cup is placed on the workpiece surface, high-quality permanent lifting, rotating the handle from the - to the "+" sign rotation number position to limit sales, check "" Whether handle security ramp is automatically locked, and then lifting. 2. When the workpiece is lifted, non-overloading, the human body is prohibited from passing below the workpiece, the workpiece is hanging temperature and ambient temperature less than 80 degrees Celsius, no severe vibration and shock. 3. When the lifting cylinder piece, should remain in contact with the workpiece V-groove of the two lines in contact, so it's only rated lifting force by 30% -50% of gravity. 4. After lifting, pressing inward handle the button to the security and health and security of the pin from the handle. Handle the "+" to "-" direction of rotation number to limit sales. So that in the closed state of the permanent lifting sucker Spot | Xinyu lifting | Jilin permanent lifting by the Qingyuan Xinyu Lifting Limited. Qingyuan Xinyu Crane Limited (xyqz0312.1688.com) to provide "chain hoists, lever hoist, electric hoist, multi-functional electric hoist, lifting machine indoor and outdoor," other business, the company has "Shanghai Yan "brands. Focus on engineering, construction cranes and other industries, have higher visibility in Baoding, Hebei. Welcomes inquiries, contact: Fanya Qi.
