【摘要】：泵的泄漏问题是工业界面临的重要问题之一。本文在对国内外文献进行归纳分析的基础上,提出了一种双层防泄漏磁力联轴器设计思想。分析了双层防泄漏磁力联轴器磁路设计方法,完成了双层防泄漏磁力联轴器的结构设计,并对传递扭矩和漏磁系数进行了计算。这种新的磁力联轴器的隔离套由双层隔套组成,该结构具有一定的新颖性,并能够起到良好的防泄漏作用。通过对磁力联轴器隔离套材料的分析,确定了磁力联轴器隔离套的材料,对本设计的隔离套的涡流损耗进行了计算,分析了隔离套的电导率、磁导率及厚度对磁场和涡流损耗的影响,提出应采取的相应的措施。在两种工况下对隔离套的强度进行了校核,证明所设计的隔离套是满足强度要求的。采用有限元方法进行分析,分析了双层防泄漏磁力联轴器的涡流损耗随着磁转角的变化规律,以及转矩与磁转角θ的关系。在理论研究的基础上,最终开发出能够应用于实际的双层防泄漏磁力联轴器。采用对比实验,对双层防泄漏磁力联轴器和相应的普通磁力联轴器传递扭矩性能进行了比较,实验表明,双层防泄漏磁力联轴器传递扭矩性能比普通磁力联轴器略有提高。将本文研制的双层磁力联轴器应用于江苏索普(集团)有限公司下属的醋酸厂的磁力泵上,取得了良好的应用效果。
[Abstract]:Pump leakage is one of the most important problems in industry. Based on the analysis of domestic and foreign literatures, a design idea of double layer leakage proof magnetic coupling is proposed in this paper. The magnetic circuit design method of double layer leakage proof magnetic coupling is analyzed, the structure design of double layer leakage proof magnetic coupling is completed, and the transfer torque and flux leakage coefficient are calculated. The isolation sleeve of the new magnetic coupling is made up of double spacers. The structure is novel and can play a good role in preventing leakage. Through the analysis of the material of the magnetic coupling isolation sleeve, the material of the magnetic coupling isolation sleeve is determined, the eddy current loss of the designed isolation sleeve is calculated, and the electrical conductivity of the isolation sleeve is analyzed. The effects of permeability and thickness on magnetic field and eddy current loss are discussed. The strength of the isolation sleeve is checked under two working conditions, and it is proved that the designed isolation sleeve meets the strength requirement. The variation of eddy current loss with magnetic rotation angle and the relationship between torque and magnetic rotation angle 胃 are analyzed by finite element method. On the basis of theoretical research, a double layer leakage proof magnetic coupling is developed. The torque transfer performance of the double layer leakage proof magnetic coupling and the corresponding common magnetic coupling is compared with that of the conventional magnetic coupling. The experimental results show that the transmission torque performance of the double layer leakage proof magnetic coupling is slightly higher than that of the ordinary magnetic coupling. The double-layer magnetic coupling developed in this paper has been applied to the magnetic pump of the acetic acid plant in Jiangsu Thorpe (Group) Co., Ltd.
