二、热水循环泵特点

1、 有刷直流水泵:水泵工作时,线圈和换向器旋转,磁钢和碳刷不转,线圈电流方向的交替变化是随着电机转动的换向器和电刷来完成,只要电机转动碳刷就会产生磨损,电脑水泵运行到一定的时候,碳刷磨损间隙变大,声音也会随之增大,连续运行几百小时之后碳刷就不能起到换向的作用了。

无刷直流磁力驱动泵的磁铁与叶轮注塑成一体组成电机的转子,转子中间有直接注塑成型的轴套,通过高性能陶瓷轴固定在壳体中,电机的定子与电路板部分采用环氧树脂胶灌封于泵体中,定子与转子之间有一层薄壁隔离,无需配以传统的机械轴封,因而是完全密封。电机的扭力是通过矽钢片(定子)上的线圈通电后产生磁场带动永磁磁铁(转子)工作运转。 对磁体进行n (n为偶数) 级充磁使磁体部分相互组成完整藕合的磁力系统。当定子线圈产生的磁极与磁铁的磁极处于异极相对,即两个磁极间的位移角Φ=0,此时磁系统的磁能最低;当磁极转动到同极相对,即两个磁极间的位移角Φ=2π/n,此时磁系统的磁能最大。

磁力泵滑动轴承的材料有工程塑料塑钢(POM)或陶瓷。由于塑钢(POM)及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。
