Magnetically driven pump, as a new type of pump, is widely used in chemical industry, pesticide, pharmaceutical, oil and electroplating industries. It can transport valuable liquid, venom and volatile liquid, and it is used as circulating water and filter water equipment. Particularly suitable for flammable and explosive liquid pumping. Mechanical seal or packing sealed centrifugal pump compared to the magnetic pump has the following advantages. 1. Pump shaft seal from the dynamic seal into a static, completely avoiding media leakage. 2. No need for independent lubrication and cooling water, reducing energy consumption. 3. Driven by the coupling into a synchronous drag, there is no contact and friction. Low power consumption, high efficiency, damping and vibration damping effect, reducing the impact of motor vibration on the pump and pump cavitation vibration on the motor. 4. Overload, the relative rotation of the rotor inside and outside, on the motor, pump protection. However, manufacturers often headaches because they do not know how to choose the magnetic pump that suits their own needs. Here, Xiaobian recommends the following two kinds of magnetic pumps to all manufacturers: A Shanghai Feng Chi Pump Co., Ltd. production of CQB magnetic drive chemical pump Triumph IMD series ã€Technical Parameters】 Power 3 ~ 30kw Speed ​​2900r / min Temperature range -20 ~ 100 ℃ Flow m3 / h ã€Working Principle】 n pairs Magnets (n is an even number) according to the law arranged in the magnetic actuator inside and outside the rotor, so that the magnet part of each other to form a complete coupling of the magnetic system. When the inner and outer two poles are in opposite polarities, that is, the displacement angle between the two poles is Φ = 0, the magnetic energy of the magnetic system is the lowest. When the poles rotate to the same poles, that is, the displacement angle Φ = 2Ï€ / n, the magnetic system at this time the maximum magnetic energy. After removing the external force, due to the mutual exclusion of the magnetic poles of the magnetic system, the magnetic force will restore the magnet to the state with the lowest magnetic energy. So the magnet produces the movement, drives the magnetism rotor to rotate. ã€Application】 IMD series magnetic pump, flow rate: 1 ~ 140m3 / h; lift 17 ~ 53m, suitable for conveying corrosive, flammable, explosive, toxic and volatile chemical media. Operating temperature: -20 ℃ ~ 100 ℃. Pump is forbidden to run in air. ã€Design Features】 IMD series of magnetic drive pump, canceled the shaft seal, the use of magnetic coupling indirect transmission, completely eliminate the phenomenon of drip. IMD series of magnetic drive pump with the latest material made of isolation sleeve with high mechanical strength completely eliminate the general magnetic pump with magnetic eddy current phenomenon. IMD series of magnetic drive pump with a unique pull-type structure, one person can easily internal maintenance and parts replacement, without removing the pipe, greatly facilitate the routine maintenance and repair work. Two Kunshan Maxima Industrial Materials Co., Ltd. production of magnetic pump IMD125-100-160-type magnetic pump [pump structure] Pump contact with the liquid part of the fluorine plastic, but the shell is a metal material, it is sufficient pump to withstand the weight of the pipeline and to withstand mechanical Sexual assault. IMD series of magnetic pumps for the motor direct-connected, supported by the middle bracket, easy installation and disassembly, compact structure, safety and energy saving. IMD125-100-160 magnetic pump is a direct motor type, supported by the middle bracket, compact structure, easy demolition, performance range: Q = 6--130m3 / hH = 20--39m; pumps are used high-performance magnetic material " NdFeB "inside and outside the magnet, the isolation sleeve using imported non-metallic materials, greatly reducing the eddy current loss, can deliver high concentration, density greater than 1.84t / m3 strong corrosive media. The main components of steel lining F46, high pump strength , Resistant to all the strong acid, alkali corrosion. The use of magnetic drive structure, to eliminate the drip, never contaminated use of the site, especially suitable for the transport of flammable, explosive, toxic, volatile and valuable medium has been put on the market in batches, at Many projects to replace the imported magnetic pump. ã€Leakproof design】 canceled the shaft seal, the use of magnetic coupling indirect drive, completely eliminating the trouble of drip, never pollute the use of the site. Due to the pump over-current part of the selection of "fluorine plastic alloy" manufacturing. Continuous delivery of any concentration of acid, alkali, strong oxidants and other corrosive media without damage. ã€Operating principle】 The driving device adopts the active magnet coupling directly on the motor shaft, the pump chamber is completely closed, and the impeller rotation on the rotor assembly is indirectly driven by the magnetic coupling. ã€Usage】 This product is widely used in: petrochemical, acid and alkali, non-ferrous metal smelting, pickling car manufacturing process, rare earth separation, pesticides, dyes, medicine, papermaking, electroplating, radio and other industries. Suitable temperature: -20 ° C - 100 ° C. Finally, Xiao Bian also remind you to use the factory, pay attention to the following in operation, so that the highest efficiency of the magnetic pump: 1. Prevent particles from entering (1) Does not allow ferromagnetic impurities, particles into the magnetic clutch and bearing friction. (2) After conveying the easily crystallized or precipitated medium, it should be rinsed promptly (after the pump is stopped, pour water into the pump chamber and discharge clean after running 1min) to ensure the service life of the sliding bearing. (3) When transporting media containing solid particles, filter at the inlet of the pump tube. 2. Prevent demagnetization (1) Magnetic moment can not be designed too small. (2) It should be run under the specified temperature, the medium temperature is strictly not allowed. A platinum resistance Temperature Sensor can be installed on the outer surface of the magnetic pump isolation sleeve to detect the temperature rise in the annulus area so as to alarm or stop when the temperature exceeds the limit. 3. Prevent dry friction (1) Do not idle. (2) It is forbidden to use the medium to empty. (3) In the case of the outlet valve is closed, the pump continuous operation time shall not exceed 2min, to prevent the magnetic actuator from overheating.
