磁力泵的特点

  1.永磁体
  1. Magnets

  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。
  From the rare-earth permanent magnetic materials, permanent magnet made of a wide range of body temperature (-45-400 ℃), high coercivity, magnetic anisotropy direction has a very good, with a very similar demagnetization does not occur when approaching the phenomenon of is a good source of the magnetic field.

  2.隔离套
  2. Isolation sets

  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。涡流的表达式为: 。其中Pe-涡流;K—常数;n—泵的额定转速;T-磁传动力矩;F-隔套内的压力;D-隔套内径; 一材料的电阻率; —材料的抗拉强度。当泵设计好后,n、T是工况给定的,要降低涡流只能从F、D、 、 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。
  Sets in when the metal isolation, isolation sets in a sinusoidal alternating magnetic fields, in the direction perpendicular to the magnetic field lines out of the cross section induced eddy currents and transformed into heat. Swirl in the expression as follows:. Where Pe-eddy; K-constant; n-pump rated speed; T-magnetic driving torque; F-compartment comprising the pressure; D-separated sets of diameter; a material resistivity; - tensile strength of materials. When the pump design is getting better, n, T is the given conditions, to reduce eddy current only from F, D,, and other considerations. Use of high resistivity, high-strength non-metallic material isolated sets of results in reducing the eddy current context is very obvious.

  3.冷却润滑液流量的控制
  3. Lubrication Liquid Flow Control

  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℃。
  Pump running, you must use a small amount of fluid set of internal magnetic separation between the rotor and the annulus area and sliding friction bearings for flushing cooling deputy. The flow of coolant pump design flow is usually 2% -3%, within a set of magnetic separation between the rotor and the annulus region due to eddy current arising from high-calorie. When the cooling lubricant inadequate or poor flushing holes to plug, it will lead to medium temperature is higher than the operating temperature permanent magnets, so that the gradual loss of magnetic properties within a magnetic rotor, so that magnetic transmission failure. When the medium is water or water-based fluid, the annulus region temperature can be maintained at 3-5 ℃; when the medium is hydrocarbon or oil when the temperature rise can annulus region maintained at 5-8 ℃.

  4.滑动轴承
  4. Bearing

  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。
  Magnetic pump sliding bearing materials impregnated graphite, PTFE and engineering ceramics. As the engineering ceramics have good heat resistance, corrosion, rubbing performance, so the sliding bearing magnetic pump to use more production of engineering ceramics. As the engineering ceramics is very crisp and the expansion coefficient is small, so bearing clearance shall not be too small to hold shaft in order to avoid an accident.

  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。
As the magnetic pump to the sliding bearing lubrication delivery media, it should be according to different media and the use of working conditions, use of different materials produced bearings.

  5.保护措施
  5. Protection

  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。
  When the magnetic actuator of the slave parts in case of overload operation or rotor stuck, the magnetic actuator of the master, slave components will automatically slip to protect pump. At this point magnetic actuator in an active permanent magnet on the rotor under the action of alternating magnetic field will produce eddy loss, magnetic loss, resulting in permanent magnet temperature, magnetic transmission slip failure.
