浅谈管网叠压供水

Discussion of Direct Network Pressure-superposed Water Supply

叠压供水可以充分利用城市管网的水压、降低能耗、减少水质二次污染,但这种给水方式需建立一定的准用条件:管网的供应能力必须满足要求,需在批准限定的流量下运行,必须具有防止负压的措施。介绍了管网叠压供水的适用条件,论述了采用管网叠压供水时应注意的问题,指出使用不当会对城市管网产生不利影响,应当是有条件的推广这种供水方式。

The direct network pressure -superposed water supply may make full use of the pressure in the municipal network. Energy saving reduces secondary pollution. But this plan must establish the ready condition. The supply ability of the pipe network must answer the purpose and operate under a limited flow. This plan must have the measure to prevent the negative pressure. In this paper, the qualification of the direct network pressure-superposed water supply is introduced, and the attentive problems of its use is discussed. Meanwhile the article points out the effect influence of the municipal pipe network in the cities when it is used inappropriately. So we should generalize it conditionally.
