Fluorine plastic magnetic pump is the application of modern magnetism principle, the use of permanent magnets to achieve non-contact indirect transmission of a chemical process pump. When the motor drives the outer rotor (ie outer magnet) assembly to rotate, the magnetic field lines move the inner rotor (ie inner magnet) assembly and the impeller synchronously through the action of the magnetic field, and the medium is completely enclosed in the stationary isolation sleeve , So as to achieve the purpose of non-leaking pumping media and thoroughly solve the shaft seal leakage of the mechanical transmission pump. The utility model is a completely sealed, leak-proof and non-polluting new industrial pump. Fluorine plastic magnetic pump is a chemical process to eliminate running, run, drip, leakage phenomenon, eliminate environmental pollution, and create a "leak-proof workshop", "leak-free factory" to achieve safe and civilized production ideal pump. How it works: Fluorine plastic magnetic pump from the pump, magnetic clutch, motor consists of three parts. The key components of the magnetic actuator consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation cover. When the motor drives the outer magnet rotor to rotate, the magnetic field can penetrate the air gap and the non-magnetic substance to drive the inner magnet rotor connected with the impeller to rotate synchronously to realize the powerless contact transmission and transform the dynamic seal into the static seal. As the pump shaft, the inner rotor is completely closed by the pump body and the isolation sleeve, thus completely solving the problems of running, running, dripping and leakage, and eliminating the leakage of flammable, explosive, toxic and harmful media through the pump seal in the refining and chemical industry Of the security risks, effectively guarantee the physical and mental health and safety of workers. Features: Fluorine plastic magnetic pump design not only has the general structure of a compact magnetic pump, good looks, small size, low noise, reliable operation, etc., and all of its current components used in the current corrosion resistance of the best in the world " Plastic King "(Fluoroplastics), the isolation sleeve made of special materials, with high mechanical strength, eliminating the magnetic eddy current phenomenon of the ordinary magnetic pump. Therefore, fluorine plastic magnetic pump can deliver any concentration (strong) acid, alkali, oxidants and other corrosive media without any damage. What if the magnetic pump encounters a problem? The following is the solution. (1) Magnetic pump shaft break. CQB-type magnetic pump shaft material used is 99% of alumina ceramic, the main reason for the shaft is broken, because the pump runs dry, the shaft bearing dry wear and tear. Open the pump inspection can be seen when the bearing has been seriously damaged to prevent the pump broken off the main method is to avoid the air pump running. (2) magnetic pump bearing damage. CQB magnetic pump bearings are made of high-density carbon material, in case of pump water or pump impurities, it will cause the bearing damage. Cylindrical coupling inside and outside the rotor between the coaxial requirements if not guaranteed, it will directly affect the bearing life. (3) magnetic pump can not play the liquid. Magnetic pump can not play the liquid pump is the most prone to failure, its reasons are more. First of all, check whether the pump suction pipe leaks, check the suction pipe air is exhausted, the amount of liquid filled in the magnetic pump is sufficient, inhalation tube whether there is debris clogging, check whether the pump is reversed (Especially after changing the motor or overhauling the power supply line), you should also pay attention to whether the suction height of the pump is too high. If the above inspection still can not be solved, the pump can be disassembled and checked to see if the pump shaft is broken. Check whether the moving ring and the static ring of the pump are intact, and whether the entire rotor can move in a small amount. If the axial movement difficulties, can check whether the carbon bearing with the pump shaft is too close. It is noteworthy that the magnetic pump repair several times to check the problem, should pay attention to the work of the magnetic coupling is normal. Bearings, inner magnetic rotors and spacers generate heat during operation, which increases the operating temperature and on the one hand reduces the power delivered and on the other hand gives rise to a great deal of hassle for the magnetic pumps that convey easily vaporized liquids. Magnetically transmitted power with temperature increases is a continuous decline in the curve, usually below the working temperature limit of the magnet, the decline of its transmission capacity is reversible, but above the limit temperature is irreversible, that is, the magnet cooling After losing the ability to pass the transfer can no longer be restored. Under special circumstances, when the magnetic coupling slips (out of step), the eddy current heat in the spacer increases rapidly and the temperature rises sharply. If it is not processed in time, the magnet will demagnetize and make the magnetic coupling fail. Therefore, the magnetic pump should design a reliable cooling system. The medium is not easy to vaporize, the cooling system is generally circulated by the impeller outlet or pump outlet leads to the liquid flow through the bearing and magnetic drive back to the suction port, the vaporization of the medium, the heat exchanger should be added or the liquid flow to the pump Of the tank, to avoid heat back to the suction port, for solid impurities or ferromagnetic impurities in the media, should consider filtering, high temperature medium, you should consider cooling to ensure that the magnetic coupling does not exceed the working temperature limit. In considering whether the speed is enough, we must first check the motor speed is normal, tachometer available for measurement, the motor speed is normal, you can consider whether there will be magnetic coupling slippage. (4) lack of lift. The reasons for this failure are: transmission medium air, impeller damage, speed is not enough, the proportion of liquid transport is too large, the flow is too large. (5) lack of traffic. The main reasons for the lack of flow are: impeller damage, speed is not enough, the lift is too high, the tube is clogged with debris and so on.
