严密性试验 meaning in Chinese
leak test
Examples
- Two commonly used methods of pressurization test of pipelines with free - surface in best common are close water test and close gas test
闭水试验和闭气试验是无压管道进行严密性试验最常采用的两种试验方法。 - To avoid the pollution of groundwater resource and adjacent environment caused by drainage pipe leakage , current criterion in our country stipulates that there must be a pressurization test before drainage pipes are used
为防止污水管道渗漏而导致污水外渗污染地下水资源和周边的环境，我国现行的规范规定，无压管道在竣工交付使用之前必须进行管道的严密性试验。 - In this paper , hydromechanical theories , three - dimensional unsteady turbulent finite volume model and pheonics software are adopted to simulate the pressure field and the velocity field of the drainage pipe in allusion to the actuality of the necessary pressurization test before being used . then analyze the computational results and figure out the variational rules of pressure and velocity with different leakage location while close water test or close gas test is applied
本文针对无压管道交付使用前必须进行严密性试验的现状，运用流体力学基本理论和三维非稳态紊流的有限体积模型，采用pheonics计算软件，数值模拟不同管径下不同漏水点的渗漏情况，模拟闭水和闭气试验时管道内部的压强场和速度场的变化，并分析计算结果，从中找出其变化规律。
