最近,空气机械在化学工业、钢铁及建筑等部门其需要量显著增长。由于对其性能要求高,因此它使用的轴封也在较严格的条件下,要求具有较完善的密封性。现有的几种密封,还不能完全满足要求。因此,为了达到完全密封的目的,人们在日以继夜地进行研究。但为了发挥最大的密封效果,最好还是先了解各种不同密封形式及性能来选定符合使用条件的密封。 下面想就整个轴封使用条件问题,特别是其中的油封和机械密封都用在什么地方及具有什么特点比较详细地叙述一下。
Recently, the demand for air machinery has increased significantly in the chemical industry, steel and construction sectors. Because of its high performance requirements, it uses the shaft seal is also more stringent conditions, requires a more perfect seal. Several existing seals, still can not fully meet the requirements. Therefore, in order to achieve the goal of complete sealing, people conduct research day and night. However, in order to maximize the sealing effect, it is best to first understand a variety of different sealing forms and properties to select the seal in accordance with the conditions of use. The following questions on the use of the entire shaft seal conditions, in particular, where the oil seal and mechanical seals are used in what place and what are the characteristics described in more detail.
