前言这是CSA C502《泥浆泵送系统基准能量因数评估》的第一版。本标准旨在作为使用基准能量系数（BEF）概念评估现有工业泥浆泵送系统整体能量性能的指南。BEF是一个系统的能耗除以在理想条件下提供相同功所需的基本能量。CSA集团承认，该标准的制定部分是由于BC Hydro、魁北克Hydro、独立电力系统运营商和马尼托巴Hydro的财政支持。本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。CSA集团已将其作为加拿大国家标准发布。范围1。1.本标准适用于具有以下特点的工业泥浆泵送系统: a） 电动单级和多级泥浆泵b）流量大于10 L/s c）平均粒径（d50）在50 um和8 mm之间d）沉降泥浆e）表现为粘性牛顿流体的泥浆（剪应力是线性的，与速度梯度成正比；f）两相（液体和固体）或三相（液体、固体和空气）泥浆g）任何粘度和h）泥浆泵送管道总长度小于100m的系统。对于较长的管道长度，见第5.4.2.1.2条排除。本标准不适用于具有以下特征的泵送系统:a）含有除水以外的输送流体的泥浆；b） 砾石和挖泥泵（平均粒径大于8mm）；和c）非沉降颗粒的浓度导致非牛顿泥浆。1.3本标准中的术语应用于表示要求，即用户为遵守本标准而有义务满足的规定； 应用于表达建议或建议但不需要的建议；可用于表示一个选项或在标准范围内允许的选项。注释随附条款不包括要求或替代要求；随附条款的注释的目的是将解释性或信息性材料与文本分开。表和图的注释被视为表或图的一部分，可以作为要求编写。附件被指定为规范性（强制性）或信息性（非强制性）以定义其应用。1.4测量单位国际单位制给出的数值为本标准中的记录单位。括号中给出的值仅供参考和比较。

PrefaceThis is the first edition of CSA C502, Benchmark energy factor assessment of slurry pumping systems. This Standard is intended as a guide to be used to assess the overall energy performance of existing industrial slurry pumping systems by using benchmark energy factor (BEF) concepts. The BEF is the energy consumption of a system divided by the essential energy required to provide the same work under ideal conditions. CSA Group acknowledges that the development of this Standard was made possible in part by the financial support of BC Hydro, Hydro Québec, Independent Electricity System Operator, and Manitoba Hydro. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope1.1 Inclusions This Standard is intended for industrial slurry pumping systems with the following characteristics: a) electrically driven single and multi-stage slurry pumps b) flowrate greater than 10 L/s c) average particle size (d50) between 50 um and 8 mm d) settling slurry e) slurry behaving as a viscous Newtonian fluid (shear stress is linear and proportional to velocity gradient; f) two-phase (liquid and solid) or three-phase (liquid, solid, and air) slurries g) any viscosity and h) slurry pumping systems with total pipe length less than 100 m. For longer pipe length, see Clause 5.4.2.1.2 ExclusionsThis Standard is not intended to be used for pumping systems with the following characteristics: a) slurries with transport fluid other than water; b) gravel and dredge pumpage (average particle size greater than 8 mm); and c) non-settling particle in concentrations that lead to a non-Newtonian slurry.1.3 TerminologyIn this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.1.4 Units of measurementThe values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
