Stainless steel water tank pressurization method of knowledge according to the standard requirement of fire tank height should be the most unfavorable point in water satisfaction system requirements, the most unfavorable point fire hydrant hydrostatic pressure not less than 7m (100m water beyond the hydrostatic pressure of not less than 15m of water), the most unfavorable point of nozzle pressure are not less than 5m of the task column if coupled with along the way and part of head loss, geometry level fire water tank, the lowest and the most unfavorable point of not less than the height of at least about 20m, which not only affects the appearance of the building, and on the design and construction of buildings also caused certain difficulties, therefore, in the stainless steel water tank top of high-rise building the ordinary is the most unfavorable point can not meet the fire hydrant or spray equipment shall be provided with water pressure, pressurized equipment.
The common equipment is pressure tank or pressure stabilizing pump. The design, if alone in the outlet pipe stainless steel water tank is arranged on the pressure pump, because there is no available for conditioning water inside the pipe network, once appear leakage scene, the pressure in the pipe network is agile down, make the pressure pump opening and closing frequently, affect the service life. The design of the use of air pressure water supply alone, there are many practical projects. In our city has been put into use in the project, designers often use pumps and pressure tanks in series compression method, confirmed by the theory, the results are very good, as shown.
Under normal conditions, the pipe pressure is maintained by a small pressure tank, the water storage trap play a major effect, small flow and low lift pump. The pump is started, the stainless steel roof fire water tank water in water pipe and pump into the fire pipe, also, a local water into the pressurized tank, the tank pressure gauge on the opening and closing control pump. Because the system has the amount of water conditioning, you can prevent the pump from time to time to start. The utility model has the advantages of simple equipment structure, small space occupation, and fire extinguishing under the condition of no electricity.
