进口磁力泵/Magnetic pump/德国巴赫
进口磁力泵（BACH）产品介绍：
泵以静密封取代动密封，使泵的过流部件完全处于密封状态，***了其他泵机械密封无法避免的跑、冒、滴、漏之弊病。泵体及过流部件的材料采用了耐腐蚀的不锈钢、刚玉陶瓷四氟石墨等材料制造。
The static seal replaces the dynamic seal, so that the flow passage parts of the pump are completely sealed, which completely solves the un***oidable defects of running, falling, dripping and leaking of other pump mechanical seals. The materials of pump body and flow passage parts are made of corrosion resistant stainless steel, corundum ceramics, tetrafluorographite and other materials.
进口磁力泵（BACH）工作条件：
1、 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℃），
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。
2、 隔离套：在采用金属隔离套时，隔离套会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，油泵设计好后，泵的额定转速和磁传动力矩由工况给定，要降低涡流只能从隔套内的压力和隔套内径等方面考虑，选用高电阻率、高强度的非金属材料制作隔离套，在降低涡流方面效果十分明显。
3、 滑动轴承：滑动轴承的材质有浸渍石墨、工程陶瓷、填充聚四氟乙烯等，由于
工程陶瓷具有耐热、耐腐蚀、耐摩擦的优点，因此磁力泵的滑动轴承多采用工程陶瓷制作。但是工程陶瓷性质很脆且膨胀系数小，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是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，选用不同材质的轴承。
4、冷却润滑液流量的控制：泵运转时必须用少量的冷却液对内磁转子与隔离套之间的环隙区域以及滑动轴承的摩擦进行冲洗冷却，冷却液的流量通常为油泵设计流量的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，当冷却液量少或冲洗孔不畅、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，磁力传动器失效。当介质为水或水基液时，可使环隙区域的温度维持在3℃--5℃；当介质为烃或油时，可使环隙区域的温度维持在5℃--8℃。
5、保护措施：当磁力传动器的从动部件在过载的情况下运行或转子卡死时，磁力传动器的主、从动部件会自动脱落，从而保护油泵。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。
1. Permanent magnets: Permanent magnets made of rare earth permanent magnets work in a wide range of temperatures (-45-400 degrees Celsius).
High tenacity, good anisotropy in the direction of magnetic field, and no demagnetization occurs when the same pole is close to each other.
2. Isolation sleeve: When using metal isolation sleeve, the isolation sleeve will be in a sinusoidal alternating magnetic field, in the vertical.
The eddy current is induced on the cross section of the magnetic line direction and converted into heat. After the oil pump is designed, the rated speed and magnetic driving moment of the pump are given by the working condition. To reduce the eddy current, we can only c***ider the pressure in the separator and the inner diameter of the separator. High resistivity and high strength non-metallic materials are selected to make the isolator to reduce the eddy current. Flow effect is very ***ious.
3. Sliding bearing: The material of sliding bearing includes impregnated graphite, engineering ceramics, filled PTFE, etc.
Engineering ceramics h***e the advantages of heat resistance, corrosion resistance and friction resistance, so the sliding bearings of magnetic pump are mostly made of Engineering ceramics. But the engineering ceramics are brittle and h***e ***all expansion coefficient, so the bearing clearance should not be too ***all, in order to ***oid shaft holding accident. Because the sliding bearing of the magnetic pump is lubricated by the medium it conveys, bearings of different materials should be selected according to different media and working conditi***.
4. Control of the flow rate of cooling lubricant: When the pump is running, a ***all amount of cooling fluid must be used to flush and cool the annulus area between the internal magnetic rotor and isolation sleeve and the friction of sliding bearing. The flow rate of cooling fluid is usually 2%-3% of the designed flow rate of the oil pump. The annular gap area between the internal magnetic rotor and isolation sleeve has high heat due to eddy current. When the cooling fluid is ***all or the flushing hole is not ***ooth and blocked, the medium temperature will be higher than the working temperature of the permanent magnet, which will gradually make the internal magnetic rotor lose its magneti*** and the magnetic drive will fail. When the medium is water or water-based liquid, the annular temperature can be maintained at 3-5 C, and when the medium is hydrocarbon or oil, the annular temperature can be maintained at 5-8 C.
5. Protection measures: When the driven parts of the magnetic drive are running under overload or the rotor is stuck, the main and driven parts of the magnetic drive will fall off automatically, thus protecting the oil pump. Under the action of alternating magnetic field of the active rotor, the permanent magnet on the magnetic drive will produce eddy loss and magnetic loss, which will cause the temperature of the permanent magnet to rise and the sliding failure of the magnetic drive.
