一、泵(组)选型要素所谓合理选泵,就是要综合考虑建设液体流量标准装置的投资和运行费用等综合性的技术经济指标,使之符合经济、安全、适用的原则。要考虑装置的最大流量、最小流量、装置扬程、装置最大功率、检定介质、装置管线规格、装置的现场情况(地理位置)等。并根据上述参数,设计装置的工艺流程图。1.最大流量是选择泵(组)的重要性能数据之一,它直接关系到整个装置的工作能力。设计泵的流量 First, the pump (group) selection factors The so-called rational selection of pump, is to consider the construction of liquid flow standard equipment investment and operating costs and other comprehensive technical and economic indicators, to make it in line with economic, security and applicable principles. To consider the maximum flow of the device, the minimum flow, the device head, the maximum power device, test medium, device pipeline specifications, site conditions (geographical location) and so on. And based on the above parameters, the design of the device process flow chart. 1. The maximum flow rate is one of the important performance data for selecting the pump (group), which is directly related to the working ability of the whole device. Design pump flow
