| With the increasing environmental protection situation, more and more chemical enterprises are required to use magnetic pumps to transport various corrosive materials. As is well known, magnetic pumps cannot idle. As long as they idle for a few minutes, the friction between the shaft and the sleeve inside them will generate extremely high temperatures, quickly wear out graphite bearings and shafts, and even burn out the inner rotor.
In recent years, domestic magnetic pump manufacturers have claimed to be able to produce magnetic pumps that are resistant to idling. Is this true? Is the idle magnetic pump really useful? Can it really idle for a long time?
Today, I will introduce several details to you, hoping to be helpful to users.
At present, there are two main types of idle magnetic pumps produced by some domestic manufacturers. One is to use ceramic rolling bearings to replace the original sliding bearings. When there is a lack of liquid inside the magnetic pump, the friction coefficient of the rolling bearings is lower, and the heat generated is relatively less. Therefore, it can idle without burning the bearings and rotors. The disadvantages of this structure are that it cannot bear high torque, materials with slightly higher density cannot be transported normally, and ceramic bearing balls are fragile.
Another type is the LHC idling fluorine lined magnetic pump developed by Green Ring. This type of magnetic pump is a complete upgrade of the main shaft and shaft sleeve on the basis of the original tradition, and is filled with nano carbon powder technology to achieve the function of idling self lubrication. Relatively speaking, the latter is more technically and theoretically in line with the requirements of idling.
