一、前言油气管道、金属贮缸、船体等表面,为了防腐蚀而涂上绝缘层。涂层厚度在0.5毫米以下的叫薄涂层,在0.5毫米以上的叫厚涂层。为了保证涂层质量,检漏仪是不可缺少的检验仪器之一。而低压检漏仪在国内是一项空白。为了解决生产急需和节省国家外汇,我们研制出该检漏仪样机,并于1984年4月通过了油田级技术鉴定。该仪器具有线路简单、工作可靠、操作方便、功耗低、体积小、重量轻等优点,是石油、化工、造船等工业不可缺少的便携式质量检验专用仪器。
First, the foreword Oil and gas pipelines, metal storage tanks, hull surface, in order to prevent corrosion and coated insulation. Coating thickness of 0.5 mm below the called thin coating, called the 0.5 mm thick coating. In order to ensure the quality of coating, leak detector is one of the indispensable testing instruments. The low pressure leak detector in the country is a blank. In order to solve the urgent need of production and save foreign exchange, we developed a prototype of the leak detector, and in April 1984 passed the field-level technical appraisal. The instrument has the advantages of simple circuit, reliable operation, convenient operation, low power consumption, small size and light weight. It is an indispensable instrument for portable quality inspection in petroleum, chemical and shipbuilding industries.
