轻钢结构厂房消防设计中的独立水幕与防火分区发布时间：2015-12-3 10:17:57 浏览次数:695
Independent water curtain fire barrier. I often use a fireproof water curtain in the hospital program zone 5 meters wide and 2 m / s flow. This method is flexible, the factory is a large span of the fire shutter door is theoretically not much of the span, the normal production, it has a fire fire partition, it can achieve a timely and effective distinction. But a water curtain fire compartment. Three big questions:
< < a >. The amount needed is too large to be high. Still to 36 meters span calculation, water curtain and drainage amount to 2 L / S M fire lasted two hours without cubic meters of ancient water curtain water having arrived audience and the content of indoor and outdoor fire hydrant fire reserves can relatively high.
< 2 >. The water curtain begins, a lot of water jet equipment, expensive suddenly caused larger losses of production. If some small fire happened in the factory, several fire extinguishing device with a gun to solve, then accidentally started fireproof Watercurtain, fear of causing water curtain of flood losses, reduce fire losses greater. The need for more stringent water curtain start period. It is only suitable for flame burning semi factory is spreading. At the beginning. Wrong Dongjak loss to stop my work of landscape design of water curtain, and most can be introduced east tree hole, generally only a few dependent massage mouth began to water curtain system, this is not to be trusted.
"Three". Effective treatment. To check the reliability of water curtain system. Theoretically, if workshop building installation to install fire facilities to re install the production equipment, a day will water curtain installation is complete, production equipment installation time also said water curtain. But in engineering practice most of the early production equipment as the most important thing, that is, the installation, fire facilities. Standing behind. The water curtain installation is complete, it always actual score how (practice makes perfect, fires to the opportunity, but if the usual examination). Ah, not working properly at the critical moment of the water curtain. What to do.
Ah, solving technical problems similar, the design of the water outlet of the fire pump room of pump water curtain can be set up test water pipe and a valve to help children usually check the water curtain pump working condition. But the factory above water curtain pipe and water curtain wall is the fountain, massage, destruction test.
