Top gas pressure fire water supply equipment

Introduction top pressure gas equipment, water supply equipment, pressure tanks, pumps, equipment consists of: pressure tank, regulator pump system, gas bottle system, steam pumps, and control systems. Regulators pump system up and running: Before you start First to the pressure tank and water filling system, filling to a certain extent, the system start-up regulator pump continues to draw water until the water level in the tank to improve the water level regulator set the upper limit of M1, the regulator pump (both a preparation of a use) automatic stop, then if the pressure in the pressure system set lower P2 (P1 upper limit for the system pressure, P2 system pressure limit) or less, the vapor pump Automatic qi into the tank until the pressure reaches the upper limit set by the regulator system when the steam pump P1 is stopped. This is the complete cycle of a regulator, then the entire fire protection system at the state regulator. When the pressure drops to P2 leak in the system, magnetic level gauge detects the tank if the water level dropped, when the water level drops below the set lower limit of M2, the regulator pump system starts automatically within the system to pay, make up the water level to the limit set by the system M1, the pump stops. (If the water tank during the pressure is too high, that is higher than the upper pressure limit set by the regulator system, then top of the tank pressure relief valve automatically opens D2 to protect the water up to the level set), If at this time the system pressure is lower than the limit set under pressure in the system, then the steam pump starts automatically qi into the tank, the pressure has been up to the upper limit set by the system when the steam pump P1 is stopped, and so forth in order to ensure regulation system runs lie within the set level (M1 --- M2) and pressure (P1 --- P2) range, to achieve the purpose of regulation. Cylinder system: Cylinder group with cylinders N only, each cylinder through a pipe with a pipe connected to the DN25, DN25 pipe connected to the top of the pressure tank, piping off D1 controlled by a solenoid valve, cylinder inside pressure (12MPa --- 15MPa) kg, outlet pressure is set to the system limit pressure less P4 = 0.42. Usually cylinder system does not work has been dormant, have to work when the fire broke out. Work process when there is a fire occurs, the system pressure regulator sharp decline, when the next down to P4, D1 open solenoid valve cylinder group, accompanied by high-pressure gas cylinders group pump high-pressure gas tank quickly hit the pressure, the pressure jar of water quickly hit the pipe, in order to ensure water supply emergency fire 10 minutes
