【摘要】：由于石油资源导致的能源短缺问题和环境污染问题，使得对废旧油液的净化、再生技术和设备受到越来越多的关注与重视。现有滤油机存在脱水效率低等问题。为了改善这一状况，提出将真空泵应用至滤油机以改善滤油机的工作真空度，从而降低滤油机的工作能耗，提高滤油机的工作效率。真空泵借助真空技术的发展，在性能和结构上具有诸多优势，其应用领域也越来越广泛，且在多种环保设备方面得以应用。涡旋真空泵的性能由真空泵型线所决定，因此，为了了解及改善真空泵，我们首先应该从理论上分析涡旋型线的特性。本文首先从真空技术出发，说明了真空泵的发展与应用，指出真空泵的性能由型线决定。而型线的构成需要符合一定的原则，通过分析型线的坐标变换和笛卡尔坐标表达式表示的一些数学意义，说明了型线构成的理论基础，为通用涡旋型线的建立提供依据。根据单一涡旋型线的共性，构造出通用涡旋型线。分析了通用涡旋型线构建的意义及其型线本身具有的数学性质。通过通用涡旋型线参数取值不同，得出不同的基础型线，说明通用涡旋型线的本源特性既是各种单一型线的集合，其本身又是一种新型的型线，能表征型线的变化规律。基于通用涡旋型线的优点，从数学角度出发，分析了通用涡旋型线表达式表征的型线构成的涡旋盘具有的厚度变化规律。利用软件MATLAB，，绘制出相应的涡旋盘图形，证实了前面理论分析的正确性。得出结论是当k=2时涡旋盘是等壁厚的，而k大于等于3时的涡旋盘就为变壁厚，且随着k值的增大，涡旋盘厚度变化趋势也在加大。而变壁厚涡旋盘在整体性能上是优于等壁厚的，说明对涡旋型线表征的涡旋盘厚度的变化是有意义的。
[Abstract]:Because of the energy shortage and environmental pollution problems caused by oil resources, so the purification of waste oil recycling technology and equipment, it is paid more and more attention. The low efficiency of the existing problem of the dehydration of oil filter. In order to improve this situation, put forward to improve the machine oil filter vacuum filter used to work oil vacuum pump, thereby reducing the energy consumption of oil filter oil filter work, improve the working efficiency of the vacuum pump. With the development of vacuum technology, has many advantages in performance and structure, its application is more and more widely, and can be used in a variety of environmental protection equipment. The performance of scroll vacuum pump by vacuum pump therefore, the line type decision, in order to understand and improve the vacuum pump, we should first analysis of characteristics of vortex type line in theory.
This paper from the vacuum technology of the development and application of vacuum pump, vacuum pump and pointed out that the performance is determined by the type of line. Which type line need to comply with certain principles, some mathematical meaning by analyzing the profile of coordinate transformation and Descartes coordinate expressions, and illustrates the theoretical basis of line form, as the general typevortex line provides the basis for the establishment.
According to the commonality of a single vortex line, constructed the general vortex type line. Analysis of the mathematical properties of meaning and type of general type vortex line construction of the line itself has. The general type vortex line parameters of different type, different from base line, single line source set is characteristic of general scroll profiles., which itself is also a kind of new type line, changes can represent the type line.
The advantages of general type vortex line from the point of view of mathematics, based on the analysis of the thickness variation of scroll plate profile of general type vortex line which has the expression characterization. Using the MATLAB software, draw the corresponding graphics scroll, verified the previous theoretical analysis. The conclusion is that when k=2 is scroll such as the wall thickness of K is greater than or equal to 3 when the scroll for variable thickness, and with the increase of K value, the change trend of the scroll plate thickness is also increasing. While the variable thickness scroll in the overall performance is better than the wall thickness, changes of scroll plate thickness on the scroll table syndrome the is of significant importance.
