1、消防泵应配备备用泵，其性能应与工作泵的性能一致，但以下建筑物可不配备备用泵：建筑高度小于54m的住宅室外消防给水设计流量小于等于25L/s的建筑物，室内消防给水设计流量小于等于10L/s的建筑物。

1. The fire pump shall be equipped with a standby pump whose performance shall be consistent with that of the working pump, but the following buildings may not be equipped with a standby pump: buildings with a building height of less than 54m, buildings with an outdoor fire water supply design flow of less than or equal to 25l/s, and buildings with an indoor fire water supply design flow of less than or equal to 10l/s.

2、消防泵的串联是将一台泵的出水口与另一台泵的吸水管直接相连，两台泵同时运行。消防泵串联可在流量恒定时增加扬程。消防泵并联是通过两台或多台消防泵同时向消防供水系统供水。消防泵并联主要是为了增加流量。

2. The series connection of fire pumps is to directly connect the water outlet of one pump with the suction pipe of the other pump, and the two pumps operate at the same time. The fire pump in series can increase the lift when the flow is constant. Parallel connection of fire pumps means that two or more fire pumps supply water to the fire water supply system at the same time. Parallel connection of fire pumps is mainly to increase the flow.

3、川消消防泵直接从市政管网抽水时，应在消防泵的出水管上安装带空气隔板的防回流装置。当吸水口无吸水井时，应在吸水口安装防旋流器。

3. When Chuanxiao fire pump directly draws water from the municipal pipe network, an anti backflow device with air baffle shall be installed on the outlet pipe of the fire pump. When there is no suction well at the suction port, an anti cyclone shall be installed at the suction port.

4、消防水池内消防泵吸水管喇叭口的有效水位不小于600mm。使用旋风防喷器时，淹没深度不应小于200mm。消防泵吸水管上应设置明杆闸阀或带自锁装置的蝶阀，但设置暗杆阀时，应设置开度刻度和标志；当管径超过DN300时，应设置电动阀。消防泵吸水管通过消防水池时，应采用柔性套管；采用刚性防水套管时，应在泵的吸入管上设置柔性接头，管径不大于DN150。

4. The effective water level at the bell mouth of the fire pump suction pipe in the fire pool shall not be less than 600mm. When using cyclone BOP, the submergence depth shall not be less than 200mm. Rising stem gate valve or butterfly valve with self-locking device shall be set on the suction pipe of the fire pump, but when setting the Non rising stem valve, the opening scale and mark shall be set; When the pipe diameter exceeds DN300, an electric valve shall be set. When the suction pipe of the fire pump passes through the fire pool, the flexible sleeve shall be used; When rigid waterproof casing is used, flexible joint shall be set on the suction pipe of the pump, and the pipe diameter shall not be greater than DN150.

5、消防泵出水管上应设置止回阀和升杆闸阀；使用蝶阀时，应配备自锁装置；当管径大于DN300时，应设置电动阀（与进水管相比）。

5. Check valve and rising stem gate valve shall be set on the outlet pipe of fire pump; When using butterfly valve, it shall be equipped with self-locking device; When the pipe diameter is greater than DN300, an electric valve (compared with the water inlet pipe) shall be set.

6、川消消防泵应能手动和自动启停，并应保证从收到泵启动信号到泵正常运行的自动启动时间不超过2分钟。消防泵应由消防水泵出水主管上设置的压力开关、高位消防水箱出水管上的流量开关或压力等开关信号直接自动启动。报警阀开关。

6. Chuanxiao fire pump shall be able to start and stop manually and automatically, and the time from receiving the pump start signal to the normal operation of the pump shall not exceed 2 minutes. The fire pump shall be directly and automatically started by the pressure switch set on the main outlet pipe of the fire pump and the flow switch or pressure switch on the outlet pipe of the high-level fire water tank. Alarm valve switch.

7、消防泵在零流量时的压力不应超过设计工作压力的140%；当出水量为设计工作流量的150%时，出口压力不应低于设计工作压力的65%。消防给水同一泵组内的消防水泵型号应相同，工作泵台数不超过3台。

7. The pressure of the fire pump at zero flow shall not exceed 140% of the design working pressure; When the water output is 150% of the design working flow, the outlet pressure shall not be lower than 65% of the design working pressure. The fire water pumps in the same pump set for fire water supply shall have the same model, and the number of working pumps shall not exceed 3.

此外，为适应消防的需要，消防泵应在结构、抗腐蚀性能、机械性能、真空密封性能、连续运转性能、引水装置等方面满足要求，更为详细的信息您可以关注我们网站www.cx-fire.com咨询了解！
