高压水射流在发动机密封垫清理去除中的应用

The new application for High Pressure Water-jet (WJ) to remove and clean sealing plate on engine connecting surface

在各种发动机的维修和翻修中 ,有大量的密封垫需去除更换。本文介绍具有诸多独特优势的高压水射流 (WJ)来解决此问题。在介绍WJ形成原理、设备构成、射流结构和技术特点的基础上 ,结合发动机箱体、缸体材料组成、结构特征 ,给出了实施方案。以摩托车发动机缸体为例 ,设计了实用的工装 ,并试验了影响效率的诸多因素和规律 ,展示了试验效果。

In this paper, the authors have carried out the high pressure water-jet (WJ) technology, which owns many advantages such as selective cutting ,cold cutting and powerful cleaning ability etc., to cope with this problem successfully, with flexible table designed and proper parameters chosen. On the basis of introduction to the forming principle, technical features and the equipment structure of WJ, and with the structure feature and materials of engine and sealing plate considered, several schedules are discussed, with adequate machining parameters and excellent results obtained, which will provide with new thoughts or approaches for similar cleaning jobs. It is proved that it is effective, flexible, safe, easy to handle and do no harm to the original machining quality or operator to use WJ to remove and clean the sealing plate on connecting surface of all kinds of engines instead of manual scraping.
