Description
本实用新型属于机器或结构部件流体密封性的测试技术领域，具体涉及一种采用压气升降水淹没工件进行检漏的升降水检漏机。The utility model belongs to the technical field of testing the fluid tightness of machines or structural parts, and in particular relates to a lifting water leak detection machine which uses compressed air to lift water to submerge workpieces for leak detection.
目前，国内外对摩托车发动机零部件的检漏有两种方法。一种是利用测漏仪对其零部件进行比较式漏气检查，其方法是直接对零件或者部件及其标准件(绝对不漏的)同时进行充气。当气体压力达到规定值后，通过传感器对其工件是否漏气进行比较式的判断。该方法由于检测时间长，仪器要求高，加上国内仪器精度低，高精度的仪器只有依赖进口，价格昂贵，所以绝大多数的生产单位很少采用这种方法，尤其是在线检漏方面更没有人采用这种方法。于是人们又采用了另一种检漏方法一水检。传统的水检是将工件的各孔洞进行封堵，并充入压气，然后将其沉入水中，观察其是否产生气泡来判断漏或不漏，以及泄漏的位置。该方法除了需要有对工件的孔洞进行封堵的机构外，还需要有一套将工件及封堵机构一并送入水中的移动装置，这样就使得机构庞大，结构复杂，而且效率也不高。At present, there are two methods for leak detection of motorcycle engine parts at home and abroad. One is to use a leak detector to perform a comparative air leakage inspection on its parts, and the method is to directly inflate the parts or components and their standard parts (absolutely leak-proof) at the same time. When the gas pressure reaches the specified value, a comparative judgment is made on whether the workpiece is leaking through the sensor. Due to the long detection time and high requirements of the instruments, and the low accuracy of domestic instruments, the high-precision instruments can only be imported and expensive, so most production units seldom use this method, especially in online leak detection. No one takes this approach. So people have adopted another leak detection method—water detection. The traditional water inspection is to seal the holes of the workpiece, fill it with compressed air, and then sink it into the water to observe whether it produces air bubbles to judge whether it is leaking or not, and the location of the leak. In addition to needing a mechanism for sealing the hole of the workpiece, this method also needs a set of mobile devices for sending the workpiece and the sealing mechanism into the water, which makes the mechanism huge, complex in structure, and not efficient.
本实用新型的目的在于针对现有检漏装置结构复杂、体积庞大、效率低等的缺点，提供一种采用压缩空气使水上升淹没工件的密封部位，观察充入压气的容腔是否漏气以及确定泄漏部位的升降水式检漏机，结构简单，检测迅速。The purpose of this utility model is to provide a sealing part that uses compressed air to make water rise and submerge the workpiece to observe whether the cavity filled with compressed air leaks and The lifting water type leak detector for determining the leakage location has simple structure and rapid detection.
