标准摘要
[中文适用范围]: 本国际标准规定了用于废水混合和其他应用的潜水搅拌器(以下简称“SM”或“搅拌器”)的验收试验方法,其中至少有一个系统组件是液体。“潜水搅拌器”是指由驱动装置和轴流式叶轮以及支持基本功能的可选部件(如护罩)组成的完全潜水式总成。“液体”是指静止时无力承受剪切应力的物体。这包括悬浮液和分散体(液/固、气/液和气/液/固)和非牛顿液体,前提是可能的小屈服应力不会阻止液体在搅拌时流动。 [外文原描述]: ISO 21630:2007 prescribes acceptance test methods for submersible mixers used for mixing in wastewater and other applications where at least one system component is a liquid. "Submersible mixer" is taken to mean a fully submersible aggregate consisting of a drive unit and an axial flow type impeller, and optional parts, such as shrouds, supporting the basic functions. " Liquid" is taken to mean a body without capacity to accommodate shear stresses when at rest. This includes suspensions and dispersions (liquid/solid, gas/liquid and gas/liquid/solid), and non-Newtonian liquids, provided that a possible small yield stress does not prevent the liquid from flowing when agitated.
