消防泵的流量和壓力參數(shù)不符合設(shè)計要求和消防技術(shù)標準，直接影響消防給水系統(tǒng)的可靠性。那么消防泵的性能參數(shù)不符合要求怎么辦？
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?
川消消防泵的選擇和應(yīng)用應(yīng)符合以下要求：
The selection and application of Chuanxiao fire pump shall meet the following requirements:
消防泵的性能應(yīng)滿足消防給水系統(tǒng)的流量和壓力要求；
The performance of the fire pump shall meet the flow and pressure requirements of the fire water supply system;
配備消防泵的驅(qū)動器功率應(yīng)滿足所選泵的流量揚程性能曲線上任一點運行所需功率的要求；
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;
使用電動消防泵時，應(yīng)選用電動干裝消防泵；
When using the electric fire pump, the electric dry mounted fire pump should be selected;
流量揚程性能曲線應(yīng)為平滑曲線，無駝峰和拐點，零流量時壓力不應(yīng)大于設(shè)計工作壓力的140%，應(yīng)大于設(shè)計工作壓力的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;
當(dāng)出水量為設(shè)計流量的150%時，出口壓力不應(yīng)低于設(shè)計工作壓力的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;
泵軸的密封方式和材料應(yīng)滿足消防泵小流量運行的要求；
The sealing mode and material of the pump shaft shall meet the requirements of low flow operation of the fire pump;
消防給水同一泵組內(nèi)的消防水泵型號應(yīng)相同，工作泵臺數(shù)不超過3臺；
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;
多臺消防泵并聯(lián)時，應(yīng)檢查流量疊加對消防泵出口壓力的影響。
When multiple fire pumps are connected in parallel, the influence of flow superposition on the outlet pressure of the fire pump should be checked.
應(yīng)對措施
Countermeasures
選擇設(shè)備和采購時，選擇流量揚程性能曲線平坦、無駝峰、額定流量、揚程和功率等參數(shù)符合設(shè)計要求的消防泵；
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;
要求生產(chǎn)廠家提供符合消防技術(shù)標準要求的消防泵流量和壓力檢測報告，或者具有檢測資質(zhì)的單位可以現(xiàn)場完成消防泵性能參數(shù)檢測，并形成檢測記錄報告。
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.xintli.net Take a look.
