自吸磁力泵是一种通过磁力传动器来实现无接触力矩传递从而以静密封取代动密封，使泵达到完全无泄漏的目的。它由自吸泵、磁力传动器、电动机三部分组成，关键部件磁力传动器由外磁转子、内磁转子及不导磁的隔离套组成。具有内封闭好、降能耗等多方面特点，使用时要注意防止颗粒进入、干摩擦等事项和问题。

主要特点：

●永磁体 由稀土永磁材料制成的永磁体工作温度范围广(-45－400℃)，矫顽力高，磁场方向具有很好的各向异性，在同极相接近时也不会发生退磁现象，是一种很好的磁场源。
●隔离套 在采用金属隔离套时，隔离套处于一个正弦交变的磁场中，在垂直于磁力线方向的截面上感应出涡电流并转化成热量。
●冷却润滑液流量的控制 泵运转时，必须用少量的液体对内磁转子与隔离套之间的环隙区域和滑动轴承的摩擦副进行冲洗冷却。冷却液的流量通常为泵设计流量的2%-3%，内磁转子与隔离套之间的环隙区域由于涡流而产生高热量。当冷却润滑液不够或冲洗孔不畅、堵塞时，将导致介质温度高于永磁体的工作温度，使内磁转子逐步失去磁性，使磁力传动器失效。当介质为水或水基液时，可使环隙区域的温升维持在3-5℃；当介质为烃或油时，可使环隙区域的温升维持在5-8℃。
●滑动轴承 磁力泵滑动轴承的材料有浸渍石墨、填充聚四氟乙烯、工程陶瓷等。由于工程陶瓷具有很好的耐热、耐腐蚀、耐摩擦性能，所以磁力泵的滑动轴承多采用工程陶瓷制作。由于工程陶瓷很脆且膨胀系数小，所以轴承间隙不得过小，以免发生抱轴事故。 由于磁力泵的滑动轴承以所输送的介质进行润滑，所以应根据不同的介质及使用工况，选用不同的材质制作轴承。
●保护措施 当磁力传动器的从动部件在过载情况下运行或转子卡死时，磁力传动器的主、从动部件会自动滑脱，保护机泵。此时磁力传动器上的永磁体在主动转子交变磁场的作用下，将产生涡损、磁损，造成永磁体温度升高，磁力传动器滑脱失效。
 

主要优点：
由于泵轴、内磁转子被泵体、隔离套完全封闭，从而彻底解决了“跑、冒、滴、漏”问题，消除了炼油化工行业易燃、易爆、有毒、有害介质通过泵密封泄漏的安全隐患，有力地保证了职工的身心健康和安全生产。
●无需安装底阀和灌引水。
●泵轴由动密封变成封闭式静密封，彻底避免了介质泄漏。
●无需独立润滑和冷却水，降低了能耗。
●由联轴器传动变成同步拖动，不存在接触和摩擦。功耗小、效率高，且具有阻尼减振作用，减少了电动机振动对泵的影响和泵发生气蚀振动时对电动机的影响。
●过载时，内、外磁转子相对滑脱，对电机、泵有保护作用。
●当磁力传动器的从动部件在过载情况下运行或转子卡死时，磁力传动器的主、从动部件会自动滑脱，保护机泵。此时磁力传动器上的永磁体在主动转子交变磁场的作用下，将产生涡损、磁损，造成永磁体温度升高，磁力传动器滑脱失效。
●强自吸、结构紧凑，外形美观，体积小，噪音低，运行可靠，使用维修方便

自吸磁力泵故障原因及解决方法：
 

Fluorine-lined magnetic pump

Self-priming magnetic pump

Fluoroplastic magnetic pump

Magnetic vortex pump

Magnetic gear pump

Stainless steel magnetic pump

The self-priming magnetic pump is a non-contact torque transmission through a magnetic actuator to replace the dynamic seal with a static seal, so that the pump can be completely leak-free. The utility model is composed of a self-priming pump, a magnetic actuator and a motor. The key component magnetic actuator is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic magnetic isolation sleeve. It has many characteristics such as good internal sealing and energy reduction. When using, care should be taken to prevent particles from entering and dry friction.

main feature:

● Permanent magnets made of rare earth permanent magnet materials have a wide operating temperature range (-45-400 ° C), high coercive force, good anisotropy in the direction of the magnetic field, and will not occur when the same pole is close. Demagnetization is a good source of magnetic field.

● Isolation sleeve When the metal isolation sleeve is used, the isolation sleeve is in a sinusoidal alternating magnetic field, and an eddy current is induced and converted into heat in a section perpendicular to the direction of the magnetic line.

● Control of the flow rate of the cooling lubricant When the pump is running, the air gap between the inner magnetic rotor and the spacer sleeve and the friction pair of the sliding bearing must be flushed and cooled with a small amount of liquid. The flow rate of the coolant is usually 2% to 3% of the pump design flow rate, and the annulus region between the inner magnetic rotor and the isolation sleeve generates high heat due to the eddy current. When the cooling lubricating fluid is not enough or the flushing hole is not smooth or blocked, the medium temperature is higher than the working temperature of the permanent magnet, so that the inner magnetic rotor gradually loses magnetism and the magnetic actuator fails. When the medium is water or water-based liquid, the temperature rise of the annulus region can be maintained at 3-5 ° C; when the medium is hydrocarbon or oil, the temperature rise of the annulus region can be maintained at 5-8 ° C.

●Sliding bearing The material of the magnetic pump sliding bearing is impregnated graphite, filled with polytetrafluoroethylene, engineering ceramics, etc. Because engineering ceramics have good heat resistance, corrosion resistance and friction resistance, the sliding bearings of magnetic pumps are mostly made of engineering ceramics. Since the engineering ceramics are very brittle and the expansion coefficient is small, the bearing clearance must not be too small to avoid the occurrence of a shaft hazard. Since the sliding bearing of the magnetic pump is lubricated by the medium to be conveyed, the bearing should be made of different materials according to different media and working conditions.

●Protection measures When the driven part of the magnetic actuator runs under overload or the rotor is stuck, the main and driven parts of the magnetic actuator will automatically slip off and protect the pump. At this time, the permanent magnet on the magnetic actuator will generate eddy loss and magnetic loss under the action of the alternating magnetic field of the active rotor, causing the temperature of the permanent magnet to rise and the magnetic actuator to slip off.

The main advantage:

Since the pump shaft and the inner magnetic rotor are completely closed by the pump body and the isolation sleeve, the problem of “running, escaping, dripping and leaking” is completely solved, and the flammable, explosive, toxic and harmful medium of the refining and chemical industry is eliminated from the pump seal leakage. The safety hazard has effectively guaranteed the physical and mental health and safe production of employees.

● No need to install bottom valve and irrigation water.

●The pump shaft is changed into a closed static seal by the dynamic seal, which completely avoids the leakage of the medium.

● No need for independent lubrication and cooling water, reducing energy consumption.

● From the coupling drive to synchronous drag, there is no contact and friction. Low power consumption, high efficiency, and damping damping effect, reducing the impact of motor vibration on the pump and the impact of the cavitation vibration of the pump on the motor.

●When overloaded, the inner and outer magnetic rotors are relatively slippery, which has a protective effect on the motor and the pump.

● When the driven part of the magnetic actuator runs under overload or the rotor is stuck, the main and driven parts of the magnetic actuator will automatically slip off and protect the pump. At this time, the permanent magnet on the magnetic actuator will generate eddy loss and magnetic loss under the action of the alternating magnetic field of the active rotor, causing the temperature of the permanent magnet to rise and the magnetic actuator to slip off.

● Strong self-priming, compact structure, beautiful appearance, small size, low noise, reliable operation, easy to use and maintain

main application:

The self-priming magnetic drive pump is suitable for industrial and urban water supply and drainage, environmental protection, construction, chemical, pharmaceutical, dye, printing and dyeing, brewing, electric power, electroplating, papermaking, industrial and mining washing, equipment cooling and so on.
