The magnetic pump bearing is typically made of high-density carbon, which is known for its durability and resistance to wear. However, if the pump is turned off abruptly or if there are impurities in the fluid being pumped, the bearing can become damaged. Additionally, improper coaxial alignment between the inner and outer magnetic rotors of the cylindrical coupling can significantly reduce the bearing's lifespan and lead to mechanical failure.

First, the working principle of the magnetic pump
The n pairs of magnets (n is even) are regularly arranged on the inner and outer magnetic rotors of the magnetic actuator, so that the magnet parts form a complete magnetic system. When the inner and outer magnetic poles are opposite poles, that is, two When the displacement angle between the magnetic poles is Φ=0, the magnetic energy is the lowest; when the magnetic pole rotates to the same pole, that is, the displacement angle between the two magnetic poles is Φ=2π/n, the magnetic energy is the largest. After the external force is removed, the magnetic force will make the magnetic poles of the magnetic system mutually repel each other. The magnet returns to the state with the lowest magnetic energy. Then the magnet generates motion to drive the magnetic rotor to rotate.
Second, the magnetic pump is the maintenance method
The material used for the magnetic pump bearing is high-density carbon. If the pump is shut off or there is impurities in the pump, the bearing will be damaged. If the coaxiality between the inner and outer magnetic rotors of the cylindrical coupling is not guaranteed, Directly affect the life of the bearing.
1. Insufficient lift
The causes of such failures are: air in the conveying medium, damage to the impeller, insufficient rotation speed, excessive proportion of the conveying liquid, and excessive flow.
2, insufficient flow
The main causes of insufficient flow are: impeller damage, insufficient rotation speed, high lift, and debris in the pipe.
3, the magnetic pump can not get liquid
The magnetic pump can't produce liquid is the most common fault of the pump. There are many reasons. First, check whether the suction line of the pump has air leakage, check whether the air in the suction pipe is exhausted, and whether the amount of liquid poured in the magnetic pump is enough. If there is any debris in the suction pipe, check whether the pump is reversed (especially after changing the motor or after the power supply line is overhauled), and also pay attention to whether the suction height of the pump is too high. Still can not solve the pump can be opened to check whether the pump shaft is broken, should also check whether the pump's moving ring, static ring is intact, the entire rotor can move a small amount of axial. If the axial movement is difficult, check whether the carbon bearing is combined with the pump shaft Too close.

Http://NewsDetail294T2.htmlChina Hardware Business Network http://news.chinawj.com.cn Editor: (Hardware Business Network Information Center) http://news.chinawj.com.cn" Magnetic pumps are widely used in industrial applications due to their efficiency and reliability. They operate based on a unique magnetic coupling system that allows the motor to drive the impeller without direct mechanical contact, reducing the risk of leaks and improving safety. The core component of this system is the magnetic rotor, which consists of two sets of magnets—inner and outer—arranged in a way that ensures optimal magnetic interaction. The working principle relies on the attraction and repulsion of magnetic poles. When the inner and outer magnets are aligned correctly, they create a stable magnetic field that enables smooth operation. However, if the alignment is off, it can cause unnecessary stress on the bearings and lead to premature wear. This is why maintaining proper coaxiality between the inner and outer rotors is crucial for the long-term performance of the pump. In terms of maintenance, regular inspection of the carbon bearing is essential. High-density carbon is chosen for its low friction and high resistance to abrasion, but it can still be damaged by sudden shutdowns or contamination from foreign particles in the fluid. To avoid this, it’s important to ensure that the pump is operated under ideal conditions and that the system is properly maintained. Common issues like insufficient lift or flow often stem from problems such as air in the system, impeller damage, or incorrect rotational speed. Troubleshooting these issues usually involves checking the suction line for leaks, verifying the impeller condition, and ensuring the pump is operating at the correct speed. In cases where the pump fails to prime, it may be necessary to inspect internal components such as the shaft, sealing rings, and the carbon bearing to identify any obstructions or damage. For users looking for specialized solutions, there are various types of magnetic pumps available, including fluoroplastic models designed for corrosive environments, self-priming versions for easier operation, and high-temperature pumps suitable for extreme conditions. These options provide flexibility depending on the specific application requirements. If you're experiencing issues with your magnetic pump or want to learn more about its operation and maintenance, consulting technical manuals or reaching out to a qualified engineer can help ensure optimal performance and longevity.
