With the intensification of the environmental protection situation, more and more chemical companies are required to use magnetic pumps to transport various corrosive materials. It is well known that magnetic pumps cannot be idled. As long as a few minutes of idling, the shafts and shafts in it The friction of the sleeve will produce extremely high temperature, which will quickly wear out the graphite bearings and shafts, and the inner rotor will be burned out if it is heavy.
In recent years, domestic manufacturers of magnetic pumps have claimed to be able to make magnetic pumps resistant to idling. Is it true? Is the idling magnetic pump really useful? Can it really idle for a long time?
Today I will introduce you to several details, hoping to help users.
At present, there are mainly two types of idler magnetic pumps produced by some domestic manufacturers. One is to use ceramic rolling bearings to replace the original sliding bearings. When the magnetic pump is deficient in fluid, the friction coefficient of the rolling bearing is lower and the heat generated is relatively small. It can run idly without burning out the bearings and rotor. The disadvantages of this structure are that it cannot carry higher torque, the denser materials cannot be transported normally, and the ceramic bearing balls are fragile.
The other is the LHC idling fluorine-lined magnetic pump developed by Green Ring . This magnetic pump is a complete upgrade of the main shaft and sleeve based on the original tradition, and is filled with nano-carbon powder technology to achieve the function of idling and self-lubrication. Relatively speaking, the latter is more in line with the idling requirements in terms of technology and actual theory.
