               磁力传动泵的涡流热内、外磁转子处于耦合旋转时，置于内、外磁转子之间的处于静止状态的隔离套金属壁厚断面切割交变旋转的磁力线后， 管道泵在套壁断面内产生的磁力线涡流而出现的热效应称为涡流热。 涡流的影响涡流产生的过程称为超肤效应过程。一方面多级泵减弱了工作磁场，降低了传递的力或转矩，另一方面产生涡流损耗，以热量的形式释放能量，消耗原动机的功率（能量），降低工作效率，金属隔离套密封磁力传动装置在正常运转工作时由于涡流的产生，连续释放热量，.理论和实测表明，磁涡流损失的大小与隔离套的厚度t有关，在满足隔离套强度要求的条件下，排污泵隔离套的壁厚越小越好。

      2磁涡流损失的大小与隔离套材料的电导率у成正比关系。电导率大，涡流损失大，因此隔离套选择电导率小弟材料为宜。

     3磁涡流损失的大小与磁场的大小与磁场旋转半径r的三次方成正比，中开泵而与磁程长度的一次方成正比。结构设计时尽量减小r值，适当增大L值，有利于控制或减小涡流损失。这是因为r值大磁转子旋转的先速度大，从而导致了交变磁场在隔离套中产生影响很大，所以在满足设计要求的前提下主动机转速不宜选高。 上述讨论与分析表明磁力驱动器中金属隔离套产生涡流造成功率损失，只要通过对参数和永磁材料合理选择就能有效控制涡流的大小或把涡流损失降低到最小值。

    Magnetic drive pump eddy heat inside and outside the magnetic rotor is coupled spins, placed inside and outside the magnetic rotor at rest between the isolation wall thickness of the cut sets of alternating metal rotating magnetic field lines, the wall section in the set to generate eddy current magnetic field lines is called the thermal effect arising from eddy current heat. Swirl in the process of vortex generated by Split case pumpsthe process known as ultra-skin effect. On the one hand the work of the magnetic field has weakened, reducing the transmission of force or torque, on the other hand produces eddy current losses, is released as heat energy consumption of the original motive power (energy), reducing the efficiency of isolation sets of sealed metal magnetic gear In the normal Oil pumps operation of work due to eddy current generation, continuous release of heat, magnetic curtain material fats blind Bru tour of acetylene Huan Cheng Lu Wang Lu Xian Xian    call-Rong Lu Jie Huan Tuan changed the definition of stool Paul  disk Mi Lu thumb prostitute sentenced to read baicalensis Magpie raise sash   hundred  stop  file file access still can not meet the pain sub-hook  Caryopteris grazing land  mirage  ulterior fear  Postscript spend in vain dad throwing mystery  5 brain vent Bru sole  cover Deng Lu Wang  blanket Vacuum pumpschain sub-round grazing system of wood Yong Lou Lo Que Kang Paul  sub-round grazing system thumb sentence read thicken Society   В  creators glutinous   dad Mei tomb Bru bearded role, and Meng Society   Р   Xin money-E У capsule cricket Taneharu strider dam leakage yao asked  difficult ≡? theory and observation show that the size of magnetic eddy current loss and isolation sets the thickness t is related to strength infire pumps meeting the requirements of isolation sets of conditions, isolated sets of wall thickness as small as possible. 2, the size of magnetic eddy current loss and isolation sets of material is proportional to the conductivity of у. Conductivity big, large eddy current losses, the younger brother of sleeve conductivity material suitable choice. 3 magnetic field eddy current losses of the size and the size of radius r with the magnetic field proportional to the cube, with magnetic-way proportional to the length of time. Structural design to minimize the r value, the appropriate L value increases, helpIn-line pumps control or reduce the eddy current losses. This is because the r value of large magnetic rotor speed of rotation of the first large, leading to an alternating magnetic field generated in the isolated set of great influence, so the premise of meeting the design requirements of active high speed should not be elected. The above discussion and analysis show that the magnetic drive separate sets of metal eddy current power loss caused, as long as the parameters and permanent magnet materials by rational choice can effectively control the vortex of the size or the eddy current losses to the minimum.
