水量、水压、水质是给水管网三要素。管网这三项机能在运行初期一般都较好,但随着使用时间的推移,会渐渐下降。管网供水机能衰减的原因复杂多样,但对这些原因逐一加以分析和研究后发现,在设计、施工和日常管理中,将这些不利因素加以防止,使给水管网长期保持良好的供水机能是能做到的。给水管网有三项机能;水量机能、水压机能和水质机能。将量、压、质都合格的水以最经济的方法送到用户,是给水管网设计、施工和管理的总则。管网的这三项机能,在刚投入运行时一般都较好,但随着使用时间的延长,会逐渐衰退。对给水管网供水机能下降原因加以细仔的分析和研究,在管网设计和施工时,即对各种不利因素加以注意,日常使用时,又将这些不利因素限制在最小范围内,防止管网供水能力下降是能做到的。如给水管网的供水机能能很好保持,不单是水量、水压和水质可加以确保,供水的成本也可降低。
Water volume, water pressure, and water quality are three elements of the water supply network. The three functions of the pipeline network are generally better at the initial stage of operation, but gradually decline with the use of time. The reason for the attenuation of the water supply function of the pipeline network is complex and diverse. However, after analyzing and studying each of these reasons one by one, it was found that in design, construction and daily management, these unfavorable factors are prevented so that the water supply network can maintain a good water supply function for a long time. Do it. The water supply network has three functions; water capacity, hydraulic pressure, and water quality. It is the general rule for the design, construction and management of the water supply network that the water that is qualified for the quantity, pressure, and quality is delivered to the user in the most economical way. The three functions of the pipeline network are generally better when they are put into operation, but they will gradually decline as the usage time increases. The analysis and study of the reasons for the decline in the water supply function of the water supply network are made. In the design and construction of the pipe network, attention is paid to various unfavorable factors. When used daily, these unfavorable factors are limited to the minimum range to prevent The decline in the water supply capacity of the net can be achieved. If the water supply system of the water supply network can be well maintained, not only the amount of water, water pressure and water quality can be ensured, but also the cost of water supply can be reduced.
