在给水管道施工中,管道安装完毕后,必须按规定要求进行水压试验,以检验管体和接口承受水压力的强度和严密性。它是检验管道安装质量的主要项目。因此,在保证管道施工质量的同时,如何确保管道试压正常进行也颇为重要。本文就管道试压中的有关问题谈一下个人的几点看法。管道在试压时,有时会因一些这样或那样的问题,而使得试压无法正常进行,下面就这些问题及其原因作一分析。 1、目前,试压泵一般都选用多级离心泵,如果水泵运行时,泵轴旋转方向相反,水泵就不出水,故无法提升管道压力,所以,试压泵在运行前,应先检查一下旋转方向是否正确,只有在确定
In the construction of the water supply pipeline, after the pipeline is installed, the hydraulic pressure test must be carried out as required to check the strength and tightness of the water pressure of the pipe body and the interface. It is the main project to test the quality of pipeline installation. Therefore, to ensure the quality of pipeline construction at the same time, how to ensure normal pipeline pressure test is also very important. This article on the pipeline pressure test about some of the views of individuals. Sometimes, due to some sort of or other problems, the test pressure will not work normally when the pipe is under pressure test. Here we will analyze these problems and their causes. 1, at present, the pressure test pump generally use multi-stage centrifugal pump, if the pump is running, the pump shaft rotates in the opposite direction, the pump does not water, it can not enhance the pipeline pressure, so the test pump before running, you should check Rotation direction is correct, only in the determination
