1. Company Profile
Shanghai Fengxian Equipment Vessel Factory was founded in 1982, and specializes in designing and manufacturing all kinds of pressure vessels. We have a high profile in the industry. And in 1998, we registered the brand of “Shen Jiang”. Our pressure vessels are widely used in petroleum, chemical, electronic, automotive, power generation, mining, pharmaceutical and other industries. Look forward to the cooperation with you in the increasingly powerful of our company.
2. Scope of application
Diaphragm pressure tank is widely used in central air conditioning circulating water regulator, steam supply expansion system, heating system circulating water replenishment regulator, fire water supply system water supply regulator, frequency water supply voltage regulator, boiler water, pressure water supply and other occasions.
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.
4. Comparison of two supercharging facilities
The system is simple and easy to operate, the system control is simple, to ensure the normal working conditions of the system is to choose a good performance of low-power pipeline pump, reliable relay open and stop device ; Power supply should ensure that the dual circuit and can automatically switch. The shortcomings of such pressurization methods are: for the pipe network leakage pressure fluctuations in the larger water supply system, pipeline pump start and stop frequently, equipment damage, high failure rate, increased energy consumption, thereby increasing operating costs. While fire safety is low.
Compared with the single pressurized system of pipeline pump, diaphragm pressure tank can not only adjust the volume (storage 30s indoor fire water), more importantly, the storage of energy. Regulator pump every time to start, you can maintain a long time pipe network pressure, the number of device starts less, low operating costs, the top of the pipe network is often in the state of water pressure, water supply safe and reliable. At the beginning of the fire, the diaphragm pressure tank not only to ensure that the top of several layers of fire hydrant and nozzle pressure requirements, but also to provide 30s indoor fire water (450L). That is, fire hydrant or nozzle at any time to meet the pressure requirements of the fire water, at this point diaphragm-type pressure tank significantly - better than booster pump. But the diaphragm pressure tank pressurization system also has shortcomings: equipment covers an area of relatively large, one-time investment is relatively high.
