引言清洗,是机械维修中的重要工艺环节,它直接关系到维修质量、成本和生产文明程度。发动机某些零件上的积炭和水垢是最难清除的两种污垢,尤其是积炭,更难清除。目前,清除积炭的方法虽有多种,如手工机具法、喷砂和喷射核屑法、化学法等,但都因存在着这样或那样的问题,不能在生产中采用。为了解决积炭和水垢的清洗问题,我们对熔盐法清除积炭、水垢进行了试验研究,取得了良好效果。
Introduction Cleaning is an important process in mechanical maintenance. It is directly related to maintenance quality, cost, and production civilization. The carbon deposits and scales on some parts of the engine are the two kinds of dirt that are the most difficult to remove, especially carbon deposits, which are more difficult to remove. At present, there are various methods for removing coke deposits, such as hand tools, sandblasting, nuclear fuel spray, and chemical methods. However, due to the existence of one or more problems, they cannot be used in production. In order to solve the problems of coke cleaning and scale cleaning, we conducted experiments on the removal of coke and scale by the molten salt method and achieved good results.
