Stainless steel fire tanks prone to problems

Stainless steel fire water tank has attractive appearance, economical and practical, and the main body is not bad for a long time. Compared with other water tanks, it has the advantages of light weight, high strength, corrosion resistance, high temperature resistance, and clean water. The following small series briefly introduces the prone problems of stainless steel fire tanks .

First, the fire tank is not set at the highest part of the building

In some large space buildings with partially-steel roofs, such as the stage of a theater, designers place the fire water tanks in the middle of the reinforced concrete structure with relatively good load-bearing capacity, but lower than the height of the most unfavorable point. Increase the lift of the booster pump to meet the working pressure requirements of the highest point sprinkler. Make the fire water tank an intermediate pool and cannot rely on gravity to supply water to the fire protection system.

Second, the fire water tank outlet pipe is not provided with check valve

Some people use fire-fighting water pipes or fire-fighting water pumps for fire-fighting water tanks to flow through fire-fighting water tanks and into the fire pipe network. These practices have reduced the pressure on the fire pipe network and cannot fully guarantee the full use of the fire fighting equipment. Therefore, the living pipe should be used to supply water to the fire tank and a one-way valve should be provided on the outlet pipe of the fire tank to prevent the water supply of the fire pump from entering. Fire water tank.

Third, the water pump outlet pipe as a fire water outlet pipe

Fire tanks often require booster pumps to meet pressure requirements. Some people use the pressurized water pump outlet pipe as the outlet pipe of the fire tank. This is a very wrong practice. The main purpose of setting the booster pump is to meet the water pressure requirements of the fire hydrants and automatic sprinkler systems before the fire pump starts in the early stage of the fire. Therefore, the booster pump installed on the roof should be provided with a bypass pipe on the side of the discharge pipe of the booster pump, and the discharge flow rate should not be less than the amount of water needed for the initial fire.
