当提升带有较大杂质的污、废水时，不同集水池内的潜水排污泵出水管不应合并排出；当提升一般废水时，可按实际情况考虑不同集水池的潜水排污泵出水管合并排诱导风机出。 排污泵吸水管和出水管流速不应小于0.7m/s，并不宜大于2.0m/s。排水泵应能自动启停和现场手动启停。 　　建筑物内使用的排水泵有潜水排污泵,液下排污泵、立式污水泵和卧式污水泵等。多台水泵可并联交替运行，也可分段投入运行。由于建筑物内一般场地较小，排水量不大，排水泵可优先采用潜水排污泵和液下排污泵，其中液下排污泵一般在重要场所使用；立式污水泵和卧式污水药品柜泵要求设置隔震基础、自灌式吸水、并占用一定的场地，故在建筑中较少使用。 　　公共建筑内应以每个生活排水集水池为单元设置一台备用泵，平时 宜交互螺旋给料机运行。不允许压力排水关与建筑内重力排水管合并排出。当集水池无法设事故排水管时，水泵应有不间断的动力供应；当能关闭排水进水管时，可不设不间断动力供应，但应设置报警装置。消防电梯集水池内排水泵流量不小于10L/s。排污泵的扬程按提升高度、管道损失计算确定后，再附加一定的自由水头。 　　自由水头宜采用0.02～0.03MPa。污水园盘给料机集水池采用潜水排污泵排水时，应设水泵固定自耦装置，方便水泵检修。单台水泵排水有可能产生倒灌时，应设止回阀。当潜水排污泵提升含有大块杂物时，潜水排污泵宜带有粉碎装置； 当提升含较多纤维物污水时，宜采用大通道潜水排污泵。 　　排污泵的流量应按生活排水设计秒流量选定；当有排水量调节时，可按生活排水{zd0}小时流量选定。地下室、设备机房、车库冲洗地面的排水，如有两台及两台以上排水泵时可不设备用泵。 　　当潜水排污泵电机功率大于等于7.5kW或出水口管径大于等于DN100时，可采用水泵固定自耦皮带输送机装置；当潜水排污泵电机功率小于7.5kW或出无极可调给料机水口管径小于DN100时，可设软管移动式安装。两台或两台以上的水泵共用一条出水管时，应在每台水圆振筛泵出水管上装设阀门和止回阀。

When upgrading the sewage with large impurities, waste water, different sets of diving inside the pool pump discharge outlet pipe should not be merged; when to upgrade the common wastewater, the actual situation may be different sets of submersible sewage pump tank outlet pipe induced fan out of the merger arrangements. Sewage pump suction pipe and outlet pipe flow rate of not less than 0.7m / s, and should not be greater than 2.0m / s. Drainage pump and on-site should be able to automatic start and stop manually start and stop. Drainage pumps for use in buildings with submersible sewage pump, liquid sewage pump, vertical sewage pumps and sewage pumps, horizontal. Multiple pumps can be run in parallel alternation can also be sub-operational. As a general venue within the building smaller, less displacement, submersible drainage pump can be given priority and the liquid sewage pump sewage pump, sewage pump liquid which is generally an important place for use; vertical and horizontal sewage pump sewage pump required medicine cabinet Set isolation base, since the irrigation-type absorbent, and occupied a certain space, it is less used in construction. Public buildings should be set for each drainage basin as a unit of life to set a standby pump, usually interactive spiral feeder should run. Does not allow the pressure off and building gravity drainage pipes discharge the merger. When the set of the pool drain incidents can not be established, the pump should have uninterrupted power supply; when to close the drainage into the water pipes, could have no uninterrupted power supply, but should set the alarm device. Fire elevator set pool pump flow within the row of not less than 10L / s. Sewage pump lift by lift height, pipe loss calculation to determine, then add some free head. Free head should adopt the 0.02 ~ 0.03MPa. Water garden pond tray feeder assembly when using submersible water pump, water pump fixed auto plant should be located to facilitate pump maintenance. Drainage pumps have a single intrusion may arise when the valve should be set. When the submersible pump to enhance large blocks of debris, the submersible sewage pump with a crushing device should; when upgrading sewage containing more fiber material, the appropriate use of large submersible sewage pump channel. Sewage pump flow should be selected water discharge in the Design Flow; when there is a displacement of regulation, the maximum hourly flow rate can be selected water discharge. Basement, equipment room, garage floor drain cleaning and, if more than two and two drainage pump device pumps from time to time. When the submersible pump motor power of 7.5kW or greater than or equal greater than or equal DN100 outlet diameter, the pump can be used fixed auto belt conveyor device; when the submersible pump motor power is less than 7.5kW Adjustable feeding or a Promise machine nozzle diameter is less than DN100, they can set up mobile hose installation. Two or more pumps share one outlet pipe should be at each water outlet pipe of circular vibrating screen to install the pump valves and check valves.
