Why Can't Magnetic Pumps Convey Particulate Media ?
TIME：2024-06-04 Author：admin Views：
Many customers don’t know that magnetic pump can’t convey media with particles, which can lead to damage to the pump. So why can’t magnetic pumps convey particulate media?
First of all, we should understand the structure and principle of magnetic pump. Magnetic pump by the pump cavity parts, magnetic drive, motor three parts.
The core component of the magnetic actuator by the outer magnetic rotor, the inner magnetic rotor and not the combination of isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can pass through the isolation sleeve to make use of the principle of homopolar repulsion and heteropolar attraction to drive the inner magnetic rotor connected to the impeller to rotate in the same direction, thus realizing the zero-contact transmission of power and making the impeller rotate to realize the effect of conveying, and the dynamic seal will be changed to the static seal here.
Because the chemical pump pump shaft, internal magnetic rotor by the pump body, the isolation sleeve is completely closed, so as to effectively solve the "running, bubbling, dripping, leakage" problem, reducing the refining chemical industry, flammable, explosive, toxic, hazardous media leakage of the safety of the use of pump seals.
In fact, this is mainly due to the friction between the rotor and stator of the chemical magnetic pump, and the lubrication required for the friction is done exclusively by the delivery medium. Therefore, if the medium contains impurities, the desired lubrication and cooling effect cannot be achieved.However, in recent years, some magnetic pumps have been able to convey liquids containing small amounts of particles.
The principle is to use some modified materials and optimize the internal structure. So even if there is a magnetic pump that can transport a small amount of particles, users should not use it to pump particles containing iron. This is because the magnetic pump itself is magnetic. If it is used to adsorb particles of iron media, it will cause adsorption and demagnetization.
The combination of the above issues still does not recommend the use of chemical magnetic pumps to convey media with particles.
