The integration of 18 cubic stainless steel fire water tank and pump is a combination of 18m #179; The volume stainless steel water tank is integrated with the fire pump set, pressure stabilization system, and intelligent control system as a fire pressure boosting and stabilization equipment. It mainly provides initial water (about 30 minutes) and stable water pressure for the building fire protection system, meeting the needs of fire hydrants and automatic sprinkler systems.
18 cubic stainless steel box pump integratedIt is a fire pressure boosting and stabilizing equipment that integrates an 18m ³ stainless steel water tank with a fire pump set, stabilizing system, and intelligent control system. It mainly provides initial water supply (about 30 minutes) and stable water pressure for building fire protection systems, meeting the needs of fire hydrants and automatic sprinkler systems.
Core parameters：
Water tank capacity: 18m ³ (18 tons of water), meeting the initial fire water demand
Common sizesApproximately 5 x 4 x 2m (length x width x height), covering an area of approximately 20 square meters
materialMainstream 304 stainless steel (food grade), 316L is selected for high corrosion environment, and BDF composite plate is selected for economical type
design pressure0.3-1.0MPa (depending on building height), ensuring that the most unfavorable point pressure is ≥ 0.15MPa
flow rangeMain fire pump 18-40L/s, sprinkler pump 3.6-15L/s
pump head：30-120m， Meet the requirements of building height and pipeline loss
powerMain pump 4-45kW, stabilizing pump 0.75-7.5kW
Comparison of Material Selection：
structural design：
Prefabricated modular structure (1m × 1m, 1m × 0.5m standard plates), bolted connection, no welding stress
Internally equipped with galvanized tie bars and column supports, the top can withstand soil pressure (buried type)
Bottom sloping design for easy drainage and cleaning
Water level control system: float valve/solenoid valve for water inlet, overflow pipe for overflow prevention, water level sensor (accuracy ± 1mm)
Typical configuration：
Characteristics of water pump：
Dry motor design, no need to exhaust air, can run directly in water
Pump casing: ductile iron or 304 stainless steel, impeller: bronze or stainless steel
Shaft seal: mechanical seal, leak proof, suitable for long-term operation
core component：
PLC control cabinet (IP68 protection): built-in fire protection program, real-time monitoring and control
Touch screen human-machine interface: displays parameters, alarm information, supports local operation
Pressure/liquid level sensor group: monitoring pipeline pressure (accuracy ± 0.02MPa) and water tank level
Remote monitoring module (optional): 4G communication, supports mobile APP/PC monitoring
Main functions：
Automatic voltage stabilization: maintain the pipeline pressure at the set value (± 0.02MPa)
Water level control: low water level alarm, high water level overflow protection
Intelligent rotation of pump sets: Balance the running time of each pump and extend the overall lifespan
Fault self diagnosis: Display the fault location, trigger the sound and light alarm, and upload it
The stabilizing pump continues to operate, maintaining the pipeline pressure at the set value (such as 0.8MPa)
The pressure tank stores approximately 100L of emergency water to reduce frequent pump starts
When there is a slight water leakage in the system, it is supplemented by the pressure tank and the stabilizing pump
Fire hydrant/sprinkler outlet → pipeline pressure drops →
The pressure sensor detects that the pressure is below the start-up threshold (such as 0.7MPa)
PLC controller starts 1 fire hydrant pump/sprinkler pump
If the pressure continues to decrease, start the backup pump (multiple pumps in parallel)
The water tank continues to supply water. When the water level drops to the low water level line, stop the water pump to prevent dry burning
After extinguishing the fire, manually/automatically reset
Restart the stabilizing pump to restore the pressure in the pipeline network
The water tank automatically replenishes water to the set water level
