一、试验目的某机所使用的密封机箱,目前均采用法兰盘橡皮圈密封,如图1所示。这种密封形式基本上能满足目前机箱设计的密封要求,但是,这种密封形式的机箱加工工艺性差,尤其是焊接工艺性差。生产过程中不易保证焊缝的致密性,使机箱的质量长期处于不稳定的状态。如何进一步提高机箱产品质量,我们考虑在提高焊接质量的同时,适当地改进机箱结构,使机箱的加工工艺性,焊接工艺性得到进一步的改进。根据这一设想,通过国外一些机箱结构的启示,我们考虑采用无法兰盘密封的结构形式。为此,进行了一次工艺试验,并在试验的基础上进行了某机箱无法兰盘密封结构的模拟试验。
First, the purpose of the test machine used by a sealed chassis, are currently used flange rubber band seal, shown in Figure 1. This form of sealing can basically meet the sealing requirements of the current chassis design, however, this sealed form chassis processing technology is poor, especially poor welding process. Production process is not easy to ensure the tightness of the weld, so that the quality of the chassis in a long period of instability. How to further improve the quality of chassis products, we consider improving the quality of welding at the same time, appropriate to improve the chassis structure, the chassis processing technology, welding process has been further improved. According to this idea, through the inspiration of some chassis structures abroad, we consider the use of non-flange seal structure. To this end, conducted a process test, and on the basis of the experiment conducted a chassis flangeless seal structure simulation test.
