Yancheng Longgang large module buried box pump integration

The underground box pump integrated fire pump station produced by Huihong Water Supply and Drainage Equipment Company is a new type of fixed fire extinguishing device designed according to the Ministry of Public Security standard GB 27898.2-2011 "Fire Automatic Constant Pressure Water Supply Equipment" and the national standard 02S101 atlas. The equipment mainly consists of stainless steel fire water tank/hot-dip galvanized steel plate water tank/SMC water tank, fire booster pump, stabilizing pump, pressure tank, control cabinet, sensors, instruments, pipeline accessories, etc; It is an ideal product to replace concrete fire water tanks, which can save more than 30% of investment. Widely applicable to various fire water supply systems such as fire hydrant systems and sprinkler systems with fire pressure boosting design requirements, such as multi story buildings, high-rise buildings, and factories and mines.

With the rapid development of modern cities and the rapid development of high-rise buildings, high-level water towers can no longer meet the water supply requirements of high-rise buildings. Under these conditions, automated water supply equipment has developed rapidly, mainly including variable frequency constant pressure water supply equipment, pipeline stacked pressure non negative pressure water supply equipment, and integrated pump stations.

The underground box pump integrated fire pump station produced by Huihong Water Supply and Drainage Equipment Company combines the advantages of variable frequency constant pressure water supply equipment and pipe network stacked non negative pressure water supply equipment. It intelligently changes the inlet water source of the equipment based on the pressure feedback of the tap water pipe network. When the tap water service pressure is high or the peak water consumption is low, it will automatically open the electric valve of the equipment's inlet water source and close the electric valve of the water tank supply; When there is a peak in water usage, it will automatically close the tap water inlet electric valve and open the water tank supply electric valve. At this time, it becomes a traditional variable frequency constant pressure water supply equipment. It will never reduce the service pressure of the water supply network.

Advantages of integrated underground box pump station:
1. Space saving: The water pump and pump chamber are placed in the water tank and fixed on a dedicated module for the integrated pump station. Normally, it only occupies a water tank capacity of 0.5-1.5m.
2. Easy to move and disassemble, long service life: Due to the use of prefabricated stainless steel water tanks, the previous welding method has been changed, and screw assembly is adopted, which has strong applicability, easy installation, and does not require specialized equipment.
3. Easy emptying: Due to the use of a new type of submersible fire pump, it can be directly submerged in water without the need for special air discharge. As long as the water tank level is within the specified level, it can directly enter the fire water supply state.
4. Frost free cracking: The fire pump is hidden deep in the water tank and will not be burned out due to freezing in winter.
5. Low noise: Equipped with a water immersed motor and water pump, it greatly reduces the operating noise.
6. Reliability: Water immersed motors will not burn out the motor or corrode the motor bearings due to rain or environmental temperature.
7. Easy to upgrade: with interfaces to support remote transmission, automatic cleaning, sterilization, and disinfection.
