1. Analysis of Pneumatic Volume of Diaphragm Pressure Tank for Fire Protection
As the initial fire flow from the diaphragm-type pressure tank supply, the pump flow only need to consider the system leakage or diaphragm-type pressure tank on the flow requirements, so the flow may be appropriate to choose a little smaller. For the fire hydrant system regulator pump flow to about less than one fire hydrant of the water, ≤ 5 L / s. Spray system The flow rate of the regulator pump is ≤ 1 L / s for less than one nozzle.
Selection method of diaphragm type pressure tank
The above two kinds of pressurized facilities have their own strengths, in the specific project should be treated separately, choose the appropriate design. For a class of high-rise buildings and important buildings, the fire caused by the huge losses, high fire requirements, should try to use diaphragm-type pressure tank pressurization facilities to solve the pressure requirements of the top several layers, and the regulator should be set to spare pump to improve The use of the reliability of the two types of high-rise buildings and ordinary dangerous buildings, due to the site, capital and other conditions, may consider only the booster pump, but in the selection of booster pump products should ensure reliable quality.
Whether it is a regulator tank or booster pump, are provided for the initial fire hydrant and nozzle water pressure protection, and the success of the initial fire is the key to control the fire, the fire can be reduced to a minimum loss.
In summary, high-rise building high-level fire tank pressurization facilities should be designed according to specific engineering control specifications; booster pump flow, head and the total capacity of the regulator tank and other parameters should also be based on different conditions to determine , Rather than mechanical application, so meet the specifications, reliable operation, economic and reasonable.

3. Installation of diaphragm pressure tank
|1. Diaphragm pressure water tank can be directly connected in parallel to the water supply pipe, water supply pipe should be installed on the bottom of the tank body to be installed sewage valve.|
|2. The room or place where the diaphragm pressure tank is to be installed shall be provided with drainage facilities, good lighting and ventilation, less dust in the environment, no corrosive gas and no freezing. Ambient temperature should be 5-40 ℃, air relative humidity should not be greater than 85%, water temperature does not exceed 60 ℃.|
|3. Diaphragm pressure water tank outdoor installation, there should be rain, sun and moisture-proof facilities, and there is no freezing in the cold season technical measures.|
|4. The distance from the top of the tank to the lowest point of the building structure shall not be less than 0.3m and the net distance between the tank wall and the wall shall not be less than 0.5m. The tank is forbidden to be strongly vibrated or impacted.|
|5. When used as a fire pressure or pressure water supply equipment, such as frequent pump start phenomenon, should be promptly check the tank gas pressure instructions.|
|6. The tank filled with gas can not contain oil to prevent the rubber diaphragm to accelerate aging.|

Diaphragm pressure tank is composed of steel shell, rubber diaphragm composed of energy storage devices. The rubber diaphragm separates the water chamber from the air chamber. The air in the tank is compressed when the outside pressure water is filled into the liner of the diaphragm type water tank. According to the Boyle gas law, the gas is compressed and the volume becomes smaller, the pressure rises and the energy is stored. The compressed gas can expand the water inside the rubber diaphragm from the tank. Such as fire pressure water supply equipment mainly by the fire main pump, regulator pump, fire control tank, pressure sensor, pressure control equipment, intelligent control cabinet and other components. The main pressure components for the capsule pressure tank, the tank filled with food-grade rubber capsules, extracorporeal inflatable phlegm, the capsule and the water system connected to both the water to prevent the wall of the device can also make the water pollution, but also Effectively eliminate water hammer phenomenon. The impact of the fire pump on the pipe network.
