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. Description


Our diaphragm pressure tank maximum working pressure were 0.6mpa, 1.0mpa, 1.6 mpa. Fire storage capacity of more than 150L, 300L, 450L. The volume of regulated water is greater than 50L. For the fire hydrant system, the water gun per share flow of 2.5L / S, 5L / S, enrich the water column length of 7M, 10M, 13M. For automatic sprinkler system, each nozzle flow is 1.0L / s, nozzle pressure is 0.1MPA. The device can make the fire water supply pipe system the most unfavorable point to always maintain the fire pressure, and the use of air pressure tank always stored 30 seconds of fire water. The equipment uses the operating pressure set by the pressure water tank to control the pump operating conditions, to achieve the function of boost regulator.


3. 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.


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.


5. 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.
