Magnetic pump is the abbreviation of magnetic drive pump. Simply put, the working principle of magnetic drive pump is based on the working principle of permanent magnet coupling. Magnetic pumps are mainly used in computer supercooling systems, water dispensers, water heater pressurization, automobile cooling circulation systems, humidifiers, and other sanitary products.
Before understanding the working principle of magnetic pump, let's take a look at the composition of magnetic pump. The magnetic pump is composed of three parts: pump, magnetic drive and motor. The key component of the magnetic drive consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, drive the inner magnetic rotor connected to the impeller to rotate synchronously, realize the contactless transmission of power, and convert the dynamic seal into a static seal. Because the pump shaft and inner magnetic rotor are completely enclosed by the pump body and the isolation sleeve, the problem of "running, emitting, dripping and leakage" is completely solved, and the leakage of flammable, explosive, toxic and harmful media in the refining and chemical industry through the pump seal is eliminated. The potential safety hazards effectively ensure the physical and mental health and safe production of employees.
N pairs of magnets (n is an even number) are assembled on the inner and outer magnetic rotors of the magnetic actuator in a regular arrangement, so that the magnet parts form a complete coupling magnetic system. When the inner and outer magnetic poles are opposite each other, that is, the displacement angle between the two magnetic poles is Φ=0, the magnetic energy of the magnetic system is the lowest at this time; when the magnetic poles rotate to the same pole, the displacement angle between the two magnetic poles is Φ=2π /n, the magnetic energy of the magnetic system is maximum at this time. After removing the external force, since the magnetic poles of the magnetic system repel each other, the magnetic force will restore the magnet to the lowest magnetic energy state. Then the magnet moves and drives the magnetic rotor to rotate.
Above we have understood the working principle of magnetic pump. There are many types of magnetic pumps, so we should pay attention to whether it meets the requirements of the device flow, head, pressure, temperature and other parameters when purchasing. The magnetic pump should be maintained regularly during use to keep it clean.
