Fluorine plastic magnetic pump working principle: Fluorine plastic magnetic pump consists of pump, magnetic drive, motor three parts. The key components of the magnetic actuator consist of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetically conductive isolation cover. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and the non-magnetic material, drive the inner magnetic rotor connected with the impeller to rotate synchronously, complete the non-contact transmission of the power, and convert the dynamic seal into a static seal. Because the pump shaft and the magnetic rotor are completely filled with the pump body and the isolation sleeve, the problem of “running, running, dripping, and leaking†is completely dealt with, eliminating the flammable, explosive, toxic, and harmful medium leakage through the pump seal in the refining and chemical industry. Peaceful hidden dangers have effectively ensured the physical and mental well-being and safe consumption of employees.
Product features: The design of fluorine plastic magnetic pump not only has the advantages of compact structure, beautiful appearance, small size, low hum and reliable operation, but also adopts the best corrosion resistance in the world. Manufactured by plastic king (fluorine plastics), the spacers are made of special materials and have high-strength mechanical properties, eliminating the magnetic eddy current phenomenon existing in common magnetic pumps. Therefore, the fluoroplastic magnetic pump can protect corrosive media such as acids, alkalis, and oxidizers without any damage.
Magnetic pump problems encountered in use:
(1) The magnetic pump shaft breaks.
The data used for the pump shaft of the CQB magnetic pump is 99% alumina ceramic. The main reason for the breakage of the pump shaft is that the shaft is twisted off due to the dry running of the pump due to the pump running. When the pump is disassembled, it can be seen that the bearing is worn. The main method of preventing the breakage of the pump is to prevent the pump from running dry.
(2) The magnetic pump bearing is damaged.
CQB magnetic pump bearings use high-density carbon materials. In the event of a water pump break or impurities in the pump, the bearings will be damaged. If the coaxiality request between the magnetic rotor inside and outside the cylindrical coupling is not guaranteed, it will directly affect the bearing life.
(3) The magnetic pump will not produce liquid.
The magnetic pump can not play the liquid is the pump most likely to show problems, its causes are also more. First of all, check whether the suction pipe of the pump is leaking at the center, check whether the air in the suction pipe can be discharged, whether the amount of liquid poured in the magnetic pump is enough, whether there is an impurity in the suction pipe, and whether there is an impurity in the pipe. Whether the pump can be reversed (especially after changing the motor or after the power line has been overhauled) should also pay attention to whether the suction height of the pump is too high. After the above checks, if it still cannot be handled, the pump can be disassembled and checked to see if the pump shaft can be broken. Also check whether the pump ring and the static ring are intact and whether the whole rotor can move in a small amount. If the axial movement is difficult, it can be checked whether the carbon bearing can be separated from the pump shaft too tightly.
It is worth noting that there are no problems with the magnetic pump after several repairs. It should be noted whether the work of the magnetic coupling can be normal. Bearings, inner magnetic rotors and spacers all generate heat during operation, which will increase the operating temperature. On the one hand, the transmitted power will drop. On the other hand, the magnetic pump that holds the easily vaporized liquid will cause a lot of trouble. The power transmitted by the magnet with temperature is a continuous drop curve. Generally, below the working temperature limit of the magnetic steel, the drop of its transmission ability is reversible, and above the limit temperature, it is irreversible, ie, the magnetic steel cooling. After that, lost transmissions can no longer be restored.
When the magnetic coupling exhibits slipping (out of step) under special conditions, the eddy heat in the spacer will increase sharply and the temperature will rise sharply. If it is not disposed of in time, it will cause the demagnetization of the magnet and cause the magnetic coupling to fail. Therefore, the magnetic pump should be designed with a solid cooling system. For a medium that is not easily vaporized, the cooling circulatory system generally draws fluid from the impeller outlet or the pump outlet, and returns to the population through bearings and magnetic transmission. For a medium that is easy to evaporate, heat exchangers should be added or the fluid should be introduced outside the pump. Storage tanks, to prevent the heat back to the suction population, should be considered on the medium with solid impurities or ferromagnetic impurities. For high temperature mediums, cooling should be considered to ensure that the magnetic coupling does not exceed the working temperature limit. When considering whether the speed can be enough, it is necessary to check whether the speed of the motor itself is normal, and the tachometer can be used to stop the measurement. Under the condition that the motor speed is normal, it can be considered whether the magnetic coupling can be slipped.
(4) The lack of lift. The causes of this problem are: there is air in the delivery medium, the impeller is damaged, the rotation speed is not enough, the specific gravity of the liquid is too large, and the flow rate is too large.
(5) lack of traffic. The main reasons for the lack of flow include: impeller damage, insufficient rotational speed, excessive lift, and debris in the tube.

Fluorine plastic magnetic pump is a kind of chemical process pump applying the principle of modern magnetism and applying permanent magnet to complete the contactless indirect drive. When the motor drives the outer rotor (ie, the outer magnet) assembly rotates, the magnetic field lines through the isolation sleeve drive the inner rotor (ie, the inner magnet) assembly and the impeller to rotate synchronously, and the medium is completely contained in the stationary isolation sleeve. In order to achieve the purpose of no leaking pumping medium, the shaft seal leakage of the mechanical transmission pump is completely dealt with. It is a new type of industrial pump with full sealing, no leakage and no pollution. Fluorine plastic magnetic pump is the ideal running pump in the process of chemical industry. It eliminates environmental pollution, invents "no leakage workshop", "no leaking factory", and completes peace and cultural consumption.
