Samarium cobalt magnets are needed in magnetic pumps, mainly because they have many characteristics suitable for the working environment and performance requirements of magnetic pumps:
High magnetism
Samarium cobalt magnets have extremely high magnetic energy product and can generate a strong magnetic field. This feature allows sufficient attraction between the driving magnet and the driven magnet of the magnetic pump to ensure reliable non-contact transmission between the driving shaft and the pump shaft. The strong magnetic field can effectively drive the impeller to rotate, ensuring the normal operation of the pump and stable flow and head output.
Good temperature stability
In high temperature environments, samarium cobalt magnets can maintain the stability of their magnetic and physical properties. In industrial applications, magnetic pumps may transport high-temperature media, such as in some chemical, energy and other fields, where the medium temperature may be high. This characteristic of samarium cobalt magnets can ensure that the magnetic transmission system of the magnetic pump can still work normally under high temperature conditions, and the magnetism will not be weakened due to temperature increase, affecting the performance of the pump.
Corrosion resistance
Samarium cobalt magnets have strong corrosion resistance and can remain stable in harsh chemical environments. Magnetic pumps are often used to transport various corrosive media, such as acid, alkali and other chemical liquids. In this environment, samarium cobalt magnets can effectively resist the corrosion of the medium, extend the service life of the magnetic pump, and reduce failures and maintenance costs caused by corrosion.
High mechanical strength
Samarium cobalt magnets have high mechanical strength and hardness and can withstand a certain degree of impact and vibration. During operation, the magnetic pump may be affected by external forces such as pipeline vibration and medium flow impact. The high mechanical strength of samarium cobalt magnets can ensure that they will not easily break or be damaged under these external forces, thereby ensuring the stable operation of the magnetic pump.
