消防泵的流量和压力参数不符合设计要求和消防技术标准，直接影响消防给水系统的可靠性。那么消防泵的性能参数不符合要求怎么办？
The flow and pressure parameters of the fire pump do not meet the design requirements and fire technical standards, which directly affects the reliability of the fire water supply system. What if the performance parameters of the fire pump do not meet the requirements?
The selection and application of Chuanxiao fire pump shall meet the following requirements:
消防泵的性能应满足消防给水系统的流量和压力要求；
The performance of the fire pump shall meet the flow and pressure requirements of the fire water supply system;
配备消防泵的驱动器功率应满足所选泵的流量扬程性能曲线上任一点运行所需功率的要求；
The power of the driver equipped with the fire pump shall meet the requirements of the power required for operation at any point of the flow head performance curve of the selected pump;
使用电动消防泵时，应选用电动干装消防泵；
When using the electric fire pump, the electric dry mounted fire pump should be selected;
流量扬程性能曲线应为平滑曲线，无驼峰和拐点，零流量时压力不应大于设计工作压力的140%，应大于设计工作压力的120%；
The flow head performance curve shall be smooth without hump and inflection point. The pressure at zero flow shall not be greater than 140% of the design working pressure and 120% of the design working pressure;
当出水量为设计流量的150%时，出口压力不应低于设计工作压力的65%；
When the water output is 150% of the design flow, the outlet pressure shall not be lower than 65% of the design working pressure;
泵轴的密封方式和材料应满足消防泵小流量运行的要求；
The sealing mode and material of the pump shaft shall meet the requirements of low flow operation of the fire pump;
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；
The fire water pump model in the same pump set of fire water supply shall be the same, and the number of working pumps shall not exceed 3;
多台消防泵并联时，应检查流量叠加对消防泵出口压力的影响。
When multiple fire pumps are connected in parallel, the influence of flow superposition on the outlet pressure of the fire pump should be checked.
应对措施
Countermeasures
选择设备和采购时，选择流量扬程性能曲线平坦、无驼峰、额定流量、扬程和功率等参数符合设计要求的消防泵；
When selecting equipment and purchasing, select fire pumps with flat flow and head performance curve, no hump, and parameters such as rated flow, head and power that meet the design requirements;
要求生产厂家提供符合消防技术标准要求的消防泵流量和压力检测报告，或者具有检测资质的单位可以现场完成消防泵性能参数检测，并形成检测记录报告。
The manufacturer is required to provide fire pump flow and pressure test reports that meet the requirements of fire technical standards, or units with test qualifications can complete the test of fire pump performance parameters on site and form test record reports.
The performance parameters of the fire pump do not meet the requirements. The above answers are given to you. You can take it as a reference to learn about it. For more equipment choices, come to our website http://www.cx-fire.com Take a look.
