eliminateFire boltBoosting and stabilizing voltageDesign of equipmentproductioninvolve multipletechnologyLink,Need to combineFire Protection CodeHydrauliccalculateAnd actualapplicationdemandThe following ismanufacturer designThis kindWhen it comes to equipmentKey pointsAnd process：


1Design Basisandstandard
1.specificationrequirement
Chinese Standard: Fire Protectionwater supplyAnd consumptionFire boltSystem TechnologyStandard "（GB50974 2014）
internationalreference：NFPA20（American Fire DepartmentassociationStandard)
Equipment requiredsatisfyquietPressuredynamic pressureTraffic volumeWaiting for parametersrequirement,Ensure the mostDisadvantage point消火Bolt pressure≥0.15MPa（high-rise building≥0.35MPa）。
2.systemtype
Temporary high voltagesystem: Commonly usedpressurizationVoltage stabilizing equipmentThe fireStart at the momentfire pump.
stablehigh-pressure system：sustainmaintainPipeline pressure, pressuredeclineAutomatic timingStartPump.

twoCoredesignparameter

actualvolumeNeed to meetspecificationminimumeffectiveVolume（Like 150L、300L）.
3. pressure controlpoint
Start the pumpPressure（P1）：pipeline networkThe pressure drops tosettingValue（Like 0.7MPa）Start at the momentmainPump.
Stop the pumpPressure（P2）: Achieveupper limitpressure(such as0.9MPa）StopPump.
pressure stabilizing pumppressure：Maintain the pipeline networkThe pressure isP1~P2between.
