Is it okay to eliminate the spray pump in the cooling spray system of the liquefied gas tank farm and use direct fire-fighting water instead? Our facility has installed 4 large tanks with a capacity of 2,000 each, and the design calls for the fire-fighting water and sprinkler water to be separate from each other. . . It has been suggested that a large amount of water is required for cooling, around 550 cubic meters per hour; the pumps used for this purpose are large, costing over 100,000 yuan each. Some people try to make do by connecting directly to the fire protection system, using that system’s water to achieve cooling, and then adding a small pump to facilitate water circulation. . . Does anyone think this opinion is correct or not? I would appreciate it if the technical experts from the two refineries could offer some guidance. Thank you. . .
It works in the same way, but it does not meet safety standards. Additionally, during the summer, a large amount of water is used for spraying, which may affect the pressure throughout the fire protection system. Personally, I recommend taking them separately.
Agree with the view from the second floor; a small system can be installed, mainly consisting of a pump, a recovery tank, and a small cooling tower.
This does not comply with fire safety regulations and causes instability in the pressure of the fire water system, resulting in the large pumps starting frequently.
The finished product storage areas here all operate separately and independently, and that’s due to what the people upstairs said. Otherwise, it won’t pass the inspection, and it will cause trouble for the user.
You mentioned that the fire water and sprinkler water are separated. In other words, the fire water system is maintained by a constant-high-pressure or high-pressure system, while the sprinkler system relies solely on the static pressure of the fire tank. Fire sprinklers are not used frequently, and in theory, their use should not cause the large pumps in the fire water system to start up repeatedly. However, in the event of a fire, there is still the issue of insufficient pressure for the spraying system connected to the tanks. Therefore, it is recommended that both the spraying system and the fire-fighting water system be connected to a pump system – either through a shared pump or separate pumps – as long as the pump has sufficient flow capacity.
What I mean is: the fire water system and the sprinkler water system combined. Some people (of course, not technical personnel, but rather certain corporate-level administrative leaders in my organization who don’t know much about technology) think that since large pumps are needed anyway, it’s better to invest all that money in the fire protection system itself, by replacing the main fire pump with one that is larger and has a higher flow rate – one that can be used both as a fire pump and as a sprinkler pump. . . But I am also aware of many disadvantages, namely the issue of how to control its use. I have not yet agreed to this idea; please help me think it through together. . . Is it appropriate or not? . . . :lol
