远离自来水厂和市政管网加压站的多层住宅区,由于管网水压降低不能满足整幢楼的给水要求,需要用户再自行加压给水。有相当多的设计者不对工程所在地段作水压调查,只在设计文件中提出给水压头要求,而不考虑管网的可资用压头,结果是不管市政管网的可资用水压能上到几楼,只要上不到顶层的,一律采取整幢楼再加压给水的方式。
Far away from the water plant and municipal pipe network pressurized station multi-storey residential area, due to the pressure drop in the pipe network can not meet the water supply requirements of the entire building, users need to self-pressurized water supply. There are quite a few designers who do not make water pressure surveys on the lot where the project is located. They only ask for the water pressure head in the design documents without considering the available pressure head of the pipe network. As a result, regardless of the available water of the municipal pipe network Pressure on the floor, as long as less than the top, all to take the whole building and then pressurized water supply.
