水泵的节能不仅关系到设计部门及制造厂的合理设计和制造,而且关系到使用单位的正确选型、科学操作和维修。本文根据参加使用单位节能的实际经验,介绍几点关于在使用现场离心泵实现节能的措施,以供使用单位参考。一、正确选型在现场实际使用的离心泵往往由于选型不合理,出现下列三种情况:(1)泵的最佳效率点的扬程H过大于现场系统装置扬程H_L,即H>H_L;(2)泵的最佳效率点扬程H小于系统装置扬程H_L,即HH_L时的节能
Energy-saving pumps not only related to the design department and manufacturing plant design and manufacture of a reasonable, but also related to the correct selection of the use of units, scientific operation and maintenance. This article according to the actual experience of energy-saving units to participate, introduce some on the use of centrifugal pumps in the site to achieve energy-saving measures for the use of units for reference. First, the correct selection of the actual use of the centrifugal pump in the field often due to the selection is not reasonable, the following three conditions: (1) the pump efficiency point of the lift H is too large than the site system device head H_L, H> H_L; (2) the best efficiency of the pump head point H is less than the head of the system H_L, H H_L energy saving
