2、实现恒压供水，调节阀门来实现恒压供水相比较，节能效果十分明显。关键词 提高供水质量 节约能源 起动平稳 可以消除水锤效应Frequency control in the application of constant pressure water supply systemAbstractAbstractIn speed-regulate of constant pressure water supply system through closed-loop control, make water supply pressure automatically maintains a consta

3、nt. Now, how much is the user water, so change often not enough water or water supply surplus situation happen from time to tome. The imbalance between two water concentrated reflection in water supply pressure, namely water much less for water pressure will be low; Water supply is less and more pre

4、ssure. Keep the constant pressure water supply may make water supply and water, namely water balance between the water is much also, when little also, when water supply water to improve the water quality. Speed-regulate of constant pressure water supply to realize, regulating valves to achieve const

5、ant pressure water supply and energy saving effects compared is very obvious.Keywords Improve water quality Save energy Start smoothly Eliminate water hammer effect 目 录1 引言（或绪论）（正文第1章，小4号宋体，行距18磅，下同） 12 ×××××× （第2章）Y2.1 ×××××× （第2章第1节） Y2.2 ×××××× （第2章第2节） Y（略）2.X ×××××× （第2章第X节） Y3 ×××××（第3章） Y（略）全文结
