/><br>管道堵漏有哪些原因<br>用于管网新、旧管道的连接，可很大的改善施工环境，使工作区间无渗水，节约水资源。减少施工成本，缩短大量的抽、排水时间，同时还解决了遇到阀门关闭不严，只能扩大停水区域，延长停水时间的难题。化工企业的生产，储运和销售等环节，常常发生泄漏，给企业带来了很大的危害。<br>管道泄漏的原因有：<br>1、人为因素<br>思想麻痹，防范意识不强，疏忽大意；二是责任不明确，考核流于形式，存在无证上岗现象；三是制度不健全，规程不详细；四是违章操作，心存侥幸，有章不循；五是责任心不强，设备不按要求保养，巡检走过场，发现问题不及时处理等；六是人员素质差，培训不到位，人员对规章、制度、规程等不了解，操作不平稳，甚至误操作。 <br>2、物的因素 <br>一是安全保护设施投入不足，二是腐蚀、裂纹、磨损、老化、外力破坏、设计不合理、制造质量差、安装不正确、工艺条件变化导致材料失效。<br>泄漏的检测<br>在生产过程中要对泄漏进行有效的治理，就要及时发现泄漏，准确地判断和确定产生泄漏的位置，找到泄漏点。特别是对于容易发生泄漏的部位和场所，通过检测及早发现泄漏的蛛丝马迹，这样，就可以采取控制措施，把泄漏消灭在萌芽状态。<br>较明显的泄漏，人们可以通过看、听、闻、摸直接感知发现，这种方法主要是依赖人的敏感性、经验和责任心。在人看不着、听不见、摸不到的场合或者比较危险的场合，往往要借助仪器和设备，进行泄漏检测。使用泄漏检测仪器能够做到在不中断生产运行的情况下，诊断设备的运行状况，判断故障发生部位、损伤程度、有无泄漏，并能准确地分析产生泄漏的原因。<br>现代科学技术的飞速进步，使管道泄漏检测技术的新方法、新成果层出不穷。特别是传感器技术、计算机技术、控制技术、人工智能技术等科学发展，推动了检漏技术向智能化、多样化、系统化的方向发展。负压波法、压力梯度法、质量平衡法、统计决策法等基于软件的检测方法和基于硬件的检测方法相结合，大大提高了检测能力、灵敏度和准确度。<br

在管道上固定一螺杆直接或间接堵住设备和管道上的泄漏处的方法，称为顶压法。这种方法适用于中低压管道上的砂眼、小洞等漏点的堵漏。<br>二、压盖法<br> 用螺栓将密封垫和压盖紧压在孔洞内面或外面达到治漏的一种方法，称为压盖法。这种方法适用于低压、便于操作管道的堵漏。<br>三、上罩法<br> 用金属罩子盖住泄漏而达到堵漏的方法，称为上罩法。<br>四、冷冻法<br> 在泄漏处适当降低温度，致使泄漏处内外的介质冻结成固体而堵住泄漏的方法，称为冷冻法。这种方法适用于低压状态下的水溶液以及油介质。<br>五、凝固法<br> 利用管道中某些物质或利用介质本身，从泄漏处漏出后，遇到空气或某些物质即能凝固而堵住泄漏的一种方法，称为凝固法。某些热介质泄漏后析出 <br> 晶体或成固体能起到堵漏的作用，同属凝固法的范畴。这种方法适用于低压介质的泄漏。如适当制作收集泄漏介质的密封腔，效果会更好。<br /></p> </div> <div class="product-sort"> <p>所属分类：<a href="https://fuwu.huangye88.com/shuixiazuoye/" title="水下作业/潜水施工">水下作业/潜水施工</a>/<a
