发动机零件泄漏检测技术及应用(中文8700字,英文5400字)
一、概述
泄漏检测技术，有时也称为试漏技术或密封性检测技术。近年来已广泛地应用于汽车制造业，如缸体水套、缸盖水套、曲轴油道孔等，此外，还有燃烧室容积测定和发动机总成检测等。
随着泄漏检测技术的应用和发展，专业厂商也已形成，比较有名望的厂商如德国的 JWFROEHLICH 公司、法国的 ATEQ 公司、美国的 U-SON 公司、Intertech公司、此外还有日本的COSM，东京测范株式公社、意大利的Microctrol等。
试漏机是由泄漏检测仪器、机械密封夹具、上下料机构等机械部件和电控系统组成。有些厂商如德国佛罗里西公司，不仅可以提供各类泄漏检测仪器，并可以提供试漏机或试漏自动线。 在泄漏检测技术中，首先要指出的是泄漏和不泄漏只是一个相对的概念，从理论上讲是没有不泄漏的，只是当泄漏的量值不超过一定的允许范围时，我们就认为是不泄漏的，或者说是合格的。

英文原文
Engine parts leak detection technology and application
First, an overview of the voice
Leak detection techniques, sometimes referred to as the test technology or sealing leakage detection technology. In recent years has been widely used in automobile manufacturing industry, such as the cylinder block water jacket, water set of cylinder head, crankshaft oil holes, etc., in addition, there are clearance volume measurement and engine assembly testing, etc.
With the application and development of leak detection technology, also has formed a professional manufacturers, more prestigious manufacturers such as Germany, French ATEQ JWFROEHLICH company, inc., United States of the U - SON company, COSM Intertech corporation, in addition to Japan, Tokyo Microctrol van type strains commune, Italy, etc.
Leaking test machine is made up of leak detection instrument, mechanical sealing clamp, up-down material mechanical parts and electric control system composition and so on. Some manufacturers such as Germany, a Florida company, not only can provide all kinds of leak detection equipment, and can provide try leakage or leakage automatic line. In the leak detection technology, the first to point out is leaking and not leak is just a relative concept, is no leakage in theory, only when the leakage quantity does not exceed certain limits, we think that is not leak, or qualified.
Second, fundamental knowledge of leakage
