Fluorine plastic magnetic pump principle and characteristics and the common troubleshooting

fluorine plastic magnetic pump is modern magnetics principles, use of permanent magnets indirect transmission of a kind of non-contacting chemical process pump. When the motor drives the outer rotor ( The outer magnetic steel) Assembly rotates, through the role of magnetic lines of force through the drive of sleeve inside the rotor, The magnet steel) Assembly and synchronous rotating impeller, completely closed in the stillness of the isolation medium set inside, so as to achieve the aim of leakfree pumping medium, thoroughly solved the mechanical transmission shaft seal of pump leaks, is the whole sealing, no leakage, no pollution of new industrial pump. Fluorine plastic magnetic pump is a chemical process to put an end to run, run, drip, leak phenomenon, eliminate the pollution of the environment, create 'no leakage workshop', 'no leak factory', to achieve an ideal pump for safety and civilized production.
how it works: fluorine plastic magnetic pump by the pump, magnetic transmission device, motor of three parts. Key components magnetic actuator by the outer magnetic rotor and inner magnetic rotor and not of permeability of sleeve. When the motor drives the outer magnetic rotor rotating magnetic field can penetrate air gap and the magnetic materials, magnetic drive is connected with the impeller in the rotor synchronous rotation, realize the power out of contact, the dynamic seal into static seal. Because of the pump body, pump shaft, the magnetic rotor of sleeve completely closed, so as to thoroughly solve the 'run, run, drip, leak problem, eliminates the oil refining chemical industry flammable, explosive, toxic and harmful medium by pump seal leakage of safe hidden trouble, effectively guarantee the staff's physical and mental health and safety in production.
product features: fluorine plastic magnetic pump design not only has ordinary magnetic pump compact structure, beautiful shape, small volume, low noisy, reliable operation, etc, and its flow components are all made of the corrosion resistance of the best in the world 'plastics king' ( Fluorine plastic manufacturing, the use of special materials of sleeve, with the mechanical properties of high strength, eliminate the magnetic eddy current of common magnetic pump existence. Therefore, fluorine plastic magnetic pump can transport any strong ( Strong) Degrees of corrosion media such as acid, alkali, oxidant and not damaged.
if magnetic pump encounter problems? The following is the solution. ( Magnetic pump shaft fracture. Type CQB magnetic pump pump shaft is the % of the alumina ceramic materials used, the main reason of pump shaft fracture is that because of empty pump running, bearing dry grinding and twist off the shaft. Can see bearing has been badly worn when disassemble pump inspection to prevent pump broken is the main way to avoid the idle running of the pump. ( Magnetic pump bearing damage. CQB magnetic pump bearing is the high density carbon materials used, in case of no water pump or pump contains impurities, can cause the damage of the bearing. Cylindrical coupling between inside and outside magnetic rotor coaxial degree requirements if not guaranteed, will directly affect the service life of bearing. ( Magnetic pump out liquid. Magnetic pump can't pump the liquid is the most prone to failure, its reason is also more. First check of the pump inlet line whether there is leakage, check whether the air suction tube, perfusion liquid volume, enough magnetic pump inhalation tube whether there is sundry jam, whether should also check the pump inversion ( Especially after the changed motor or power lines after the repair, should also pay attention to the pump suction height is too high. Through the above check if still can't solve, can disassemble the pump, the pump shaft is broken, you should also check the pump ring and static ring are in good condition, the rotor can be a small amount of axial movement. If axial movement difficulty, can check whether the carbon bearing is combined with pump shaft is too tight. It is important to note that magnetic pump repaired a few times did not find problems, work should pay attention to the magnetic coupling is normal. Bearing, the magnetic rotor and isolation sets in operation will produce heat, this will make the working temperature, on the one hand, the transfer of power down, on the other hand to transport easily vaporized liquid magnetic pump can produce a lot of trouble. Magnetic steel represents the power with the rise of temperature of a continuous decline curve, usually, working in the magnetic steel under extreme temperature, its transmission capacity decline is reversible, and above the limit temperature is irreversible, namely magnetic steel cools, the loss of transmission capacity can no longer be restored. Under special circumstances in the magnetic coupling occurrence surge ( Loss of step, the casing of the eddy current heat will increase sharply, rapid temperature rise, if not handled in time, will cause magnetic steel demagnetization, disable magnetic coupling. Therefore magnetic pump should be reliable cooling system design. Medium of not easy vaporization cooling circulatory system generally consists of the impeller outlet or exit flow pump, the bearings and magnetic transmission part back to absorb population, medium for easy vaporization, heat exchanger should increase or will flow to the pump outside the tank, avoid heat back to absorb population, for medium with solid impurities or ferromagnetic impurities, filtering, should be considered for high temperature medium, should consider to cooling, to ensure that the magnetic coupling work shall not exceed the limit temperature. When considering whether speed is enough, to check whether the speed of the motor itself is normal, tachometer measurements are available, and under the normal operation of the motor speed, can consider to whether there will be a slippage of magnetic coupling. ( Lack of lift. Of the cause of the failure are: the transmission medium is air, the impeller is damaged, speed is not enough, the proportion of conveying liquid is too big, too much traffic. ( Lack of traffic. Caused the main reasons of the lack of flow are: the impeller damage, speed is not enough, the head is too high, the tube with sundry jam, etc.
