How to fill in the static pressure and dynamic pressure in the fire hydrant test records in fire control engineering?
For example: check the first floor two fire hydrant outlet pressure is 0.4MPa, pressure is 0.65MPa; two days at the hydrant outlet pressure is 0.2MPa, pressure is 0.3MPa, around the fire hydrant tests test meets the design requirements.
Connect the hose, open the water cannon, test the dynamic pressure, start the fire pump, the dynamic pressure should not be greater than 0.5MPA. Fill in the test and fill in the amount of data
This is not calculated in your project completion and acceptance, there is a fire hydrant fire brigade specialized testing tools (water gun connected to the pressure gauge), it is not the first static test, the test pressure in the pipe network, the general should not be greater than 1.0MPA.
