How to do the hydrant water pressure gauge and how much water pressure do the hydrant need?
In the high-pressure, temporary high-pressure fire water supply system, no matter whether the water gun is at the top of any building, the full water column of the water gun should not be less than one 0m.
When the building height of not more than 00 meters, the maximum negative point of high-rise building fire hydrant hydrostatic pressure should not be less than 0 MPa when the height of the building paint; more than 00 meters, the maximum negative point of high-rise building fire hydrant hydrostatic pressure should not be less than 0. 5MPa; 5. water hydrant mouth pressure should not be greater than.00MPa, when more than one.00MPa, should take the water system. When the water pressure of hydrant hydrant is greater than 0.5MPa, measures should be taken to reduce the pressure
Indoor fire hydrant should adopt high pressure or a temporary high-pressure water supply system, when the indoor fire water reached the maximum when the water pressure should satisfy the most unfavorable point indoor fire extinguishing facilities; water pressure low pressure water supply pipeline outside, when the life, production and fire water reached the maximum, should not be less than 0. MPa.
When the fire hydrant and sprinkler are opened at the same time, the water pressure should satisfy all the equipment used on the opening and maintain enough water column length.
