Series-parallel pressure-superposed water supply system
The invention discloses a series-parallel pressure-superposed water supply system which comprises primary lifting equipment and secondary lifting equipment which are located in the same pump room and arranged in series. The primary lifting equipment comprises a plurality of first water pumps connected in parallel, and the secondary lifting equipment comprises a plurality of second water pumps connected in parallel; the water inlet end of the primary lifting device is connected with a municipal water supply pipe or connected with the municipal water supply pipe through a cutoff water tank, and the water outlet end of the primary lifting device is connected with a first water supply pipe used for directly supplying water to users in a secondary high partition and connected with the water inlet end of the secondary lifting device in parallel. And the water outlet end of the second-stage lifting equipment is connected with a second water supply pipe for supplying water to users in the highest partition. The system is suitable for secondary water supply of the highest two subareas of a high-rise building about 100 meters, and the problems that during subarea parallel water supply, the flow of the second water pump of the highest water supply subarea is small, the lift is large, the Q-H curve is steep, the efficient section is narrow, and the energy-saving effect is poor are solved.
本发明公开了一种串并联叠压供水系统，包括位于同一泵房内且串联设置的初级提升设备和二级提升设备；初级提升设备包括多个并联的第一水泵，二级提升设备包括多个并联的第二水泵；初级提升设备的进水端与市政供水管连接，或者通过断流水箱与市政供水管连接，初级提升设备的出水端与用于向次高分区用户直接供水的第一供水管连接，并且同时并联与二级提升设备的进水端连接，二级提升设备的出水端与向最高分区用户供水的第二供水管连接。该系统适用于近百米高层建筑最高两个分区的二次供水，解决了分区并联供水时最高供水分区第二水泵的流量偏小而扬程很大，Q‑H曲线陡，高效段狭窄，节能效果差的问题。
