关于泄漏检测的方法及其应用【摘要】介绍了发动机油水混合问题产生的原因和采用试漏工艺的必要性，以及几种常用的泄漏检测方法及选用原则，并对试漏机的类型和密封件的结构设计方法进行了分析，最后对影响气密性检测仪检测精度的一些关键因素进行了讨论。
【关键词】油水混合，检测方法，试漏机，密封，泄漏1 引言发动机出现油水混合的问题，即水箱内有油或油底壳内有水，有的这两种现象都存在，使水温容易升高，冷却性降低和机油变质，严重影响发动机的正常使用与汽车产品的信誉，并给用户带来重大抱怨。
当前使用一种廉价易取的空气介质作为测量流体的气压式泄漏检测装置在国内汽车行业发动机的缸体、缸盖等重要零部件中得到了广泛的应用，这种装置大大提高了检测效率，降低了成本，保证了产品质量。
2 发动机油水混合的主要原因和改进措施发动机缸体、缸盖内部均设有循环冷却水套、润滑油道及不少螺栓、螺孔等，通过多次调查和试验发现，这也是油水混合最常见的渗漏处。
产生这种油水混合现象的原因，主要是缸体、缸盖毛坯铸造质量上存在局部组织疏松与试漏工艺水平低、可靠性差。
因为在水压试漏时，只能见到冒汗或浸润现象，而缸体、缸盖油孔周围部分组织如有疏松，就根本看不清，不能检出所有渗漏的零件，有可能使轻微的或局部组织疏松的零件装机。
发动机在工作时，由于温度升高受热膨胀，致使压力较高的润滑油从疏松的油道孔周围窜入压力较低的水套内，循环至水箱；或者使冷却水从缸体、缸盖的水套壁及缸孔、挺杆孔的周围部分，直接或间接地漏入发动机的油底壳内，也有的是由于铸造或机械加工误差引起各种孔道壁薄，或水泵密封面密封不严，引起油水窜通。
为了提高产品质量，在制造过程中，必须彻底消除引起发动机油水混合的一切可能因素，主要措施有下列几个方面。
（1）首先要提高铸造工艺水平，保证铸件质量，降低铸件的渗漏废品率。
（2）在铸造线上增设试漏工艺，以便及时了解铸造质量，同时保证做到不使大量有泄漏的铸件送往机加工，以免造成人力、物力浪费。
