2) variable frequency water supply
变频供水
1.
Therefore, electricity consumption per kiloton-water is very high after using variable frequency water supply mode in a lot of villages and towns.
当前深水井大多采用变频调速控制,但由于水泵低速运行效率很低,导致小流量供水期间"费电"问题突出,因此不少村镇在改用变频供水模式后千吨水能耗指标很高。
2.
The fault tree of variable frequency water supply equipment is established and analyzed qualitatively and quantitatively in this paper.
本文通过对变频供水设备建立故障树,并对其进行定性、定量分析,揭示了故障树分析(FTA)对提高产品性价比的重要意义。
3) variable-pressure water supply
变压供水
1.
The energy consumptions of constant-pressure water supply and variable-pressure water supply are studied.
基于某泵站水泵运行数据、运行图、变速状态下流量和泵效的关系得出了转速及流量与百吨水能耗的变化趋势,发现恒压供水调速、调流范围小,小流量供水时能耗趋势上升,而变压供水调速、调流范围宽,小流量供水时能耗趋势下降,并从变速范围、水泵高效区范围和百吨水能耗指标3个方面对比了恒压供水与变压供水的优劣,结果表明变压供水比恒压供水能降低能耗20%以上。
5) "Harmonious" water supply corporate culture
"和谐"供水企业文化
6) frequency-conversion and speed-adjusting water supply
变频调速供水
1.
Based on the analysis of operation condition of centrifugal pumps,the applicability of frequency-conversion and speed-adjusting water supply system was studied,and main parameters for type-selection with high operation efficiently of the system were proposed.
在水泵选型和运行调度都合理时,变频调速供水系统才可取得预期的节能效果,小流量条件下需辅以气压给水技术节能。
