The invention discloses a novel magnetic connection structure for a peristaltic pump, and relates to the technical field of precise instruments in a fluid pump. The structure is used between a driver and a pump head, and is characterized in that the structure comprises a first magnetic drive and a second magnetic drive; the first magnetic drive and the second magnetic drive are oppositely arranged in a no-contact manner; the first magnetic drive is disposed on the main drive shaft of the driver, and the second magnetic drive is disposed on a pump head transmission shaft of the pump head. According to the invention, the direct contact-type power transmission is changed into synchronous pulling, and there is no contact and friction. The power consumption is small, and the noise is small. The structure has an effect of damping, reduces the impact on the pump head from the vibration of a motor, and reduces the impact on the motor from the vibration of the pump head and overload.
Description
technical field [0001] The invention relates to the technical field of precision machinery in fluid pumps, in particular to a novel magnetic connection structure of a peristaltic pump. Background technique [0002] Magnetic transmission is the use of magnets that can attract ferromagnetic substances and the characteristics of magnetic force between magnets or magnetic fields, while non-ferromagnetic substances do not affect or rarely affect the magnitude of the magnetic force, so they can pass through non-magnetic conductors (isolation sleeves) without contact or air) for power transmission. Arranging and assembling n pairs of magnets (n is an even number) regularly on the active and driven magnetic rotors of the magnetic connection device, so that the magnet parts form a complete coupled magnetic force system with each other. When the two magnetic poles are opposite to each other, that is, the displacement angle between the two magnetic poles Φ = 0, the magnetic energy of ...
