The structure of the stabilized pump system to realize the stabilized pressure
1. Cylinder system
The gas cylinder group is equipped with gas cylinders, which are connected to the top of the air pressure water tank through pipelines. The on-off of the pipelines is controlled by solenoid valves. The pressure in the gas cylinders is 12MPa~15MPa, and the outlet pressure is set below the lower limit pressure of the system. The gas cylinder system is always in a dormant state at ordinary times. When a fire occurs, when the pressure of the voltage stabilizing system drops sharply, when it drops below the lower limit pressure, the solenoid valve of the gas cylinder group opens, and the high-pressure gas of the gas cylinder group is quickly pumped into the air pressure water tank. , The water in the air pressure water tank is quickly pumped into the fire pipe to ensure a 10-minute emergency fire water supply.
2. Steam pump system
The steam pump system can be equipped with one large and one large steam pump. Among them, the large steam pump is also in a dormant state at ordinary times, and it will only start when the small steam system fails. Because the gas consumption in the process of stabilizing the pressure is very small, the small steam pump is usually only used for stabilizing the pressure. The outlet pipeline of the steam pump system is connected to the top of the air pressure water tank, and each steam pump outlet is equipped with a one-way valve to ensure that the stabilized gas and water will not flow back into the air pump. When the pressure of the stabilizing system drops to the set lower limit, the small steam pump starts to pressurize the stabilizing system and the pipeline until the pressure reaches the upper limit of the set value, and the steam pump stops. When the small steam pump fails or the pressure drops sharply, the large The steam pump is turned on to complete the pressure stabilization process. Repeated operation in this way ensures that the pressure stabilizing system is stable within the set pressure range, achieving the purpose of backing up and stabilizing the large and small air pumps.
The principle of start-up and operation of the pressure-stabilizing pump system
Before the equipment is started, first use the pressure of the water source to fill the air pressure water tank and the system. After starting the pressure stabilizing pump, continue to draw water to the system until the water level in the air pressure water tank is raised to the upper limit of the set water level and automatically stops. At this time, if the pressure is below the lower pressure limit set by the system, the steam pump will automatically replenish air into the tank until the pressure reaches the set pressure upper limit of the pressure stabilization system, and the steam pump will stop. This is the completion of a voltage stabilization cycle, at which point the entire fire protection system is in a voltage stabilization state.
When a fire accident occurs, the pipeline of the fire protection and sprinkler system is opened, and the pressure of the voltage stabilizing system drops rapidly. The pressure in the air pressure water tank is suppressed, and the pressure in the air pressure water tank increases instantly. At this time, the high-pressure gas of the system quickly injects water into the fire-fighting pipeline, ensuring that the 10-minute emergency fire-fighting water quickly enters the fire-fighting system to achieve the purpose of fire-fighting emergency water to rescue property and personal safety.
