Why now popular pressure delivery outlet pressure delivery outlet is widely used in building a new staircase front room, smoke shaft wall, still widely used in piping side exhaust system or air terminal. Pressure delivery outlet more and more people loved and welcomed. Then the pressure delivery outlet why so popular? Positive pressure blower usually normally closed, electric, manual open open, the starter signal output, manual reset closed positive pressure blower price, 280 ℃ temperature sensor operation, the valve is closed again. Positive pressure blower using thin body, reduce operating box size to increase the effective area of ??the ventilation exhaust. When a fire occurs, the internal air pressure delivery of the actuator is open air, temperature sense smoke or manual fire alarm will open, positive pressure blower tower roof open automatically, for blowing pressurized air shafts, stairs front compartment by a steady stream of pressurized air outlet will air on the front chamber, the front chamber to maintain a positive pressure to ensure that smoke does not spread in the region, while giving space to escape. When the temperature is higher than 280 ° C person has no possibility of escape, the internal fuse will blow the roof of positive pressure blower outlet automatically shut down to prevent the fire from spreading. Therefore, pressure delivery outlet has an extremely important role, and then more and more popular. Positive pressure blower installation than the transfer value is kind of how? Without positive pressure type blower, having a different ratio of the diameter D, and the speed factor, the drawing speed of the cross-seat coefficient than the diameter of the vertical axis of the figure back to the different types of positive pressure blower maximum total pressure efficiency curve and the circumferential speed u line, design fan, you can use to choose the right type impeller. Positive pressure blower shaft speed should during each test point of the experiment, were measured periodically to ensure that the average shaft speed error does not exceed ± 0.5%. Should not be used for positive pressure blower speed or positive pressure blower performance has a greater impact measuring device. Such measurements are very suitable ways and means, and also very simple. When making a direct positive pressure blower installed equipment installed in the pipe or fan speed measurement can be carried out anywhere. Positive pressure blower can be roughly estimated maximum efficiency value of positive pressure blower, mobile point if you choose the d curve for maximum efficiency, it would be difficult to achieve maximum efficiency ventilator, positive pressure blower, for a model of fan impeller by the above equation swf positive pressure blower, which is larger than the diameter and speed coefficient. The model of positive pressure blower impeller located under the curve d, it is not efficient. As positive pressure blower how to install it, it is possible to install the supplied installation dimensions of the indoor walls punctured on the way, it will be more convenient, like household electricity voltage is 220V, so people can subscribe to 220V electricity. Pressurized air supply unit _ pressure blower (certified) _ positive pressure blower is provided by the Texas Huaxin air-conditioning plant. Texas Watson conditioning plant (www.wchuaxin.com) (www.wchuaxin.com) Shandong Dezhou, heat, refrigeration and air conditioning equipment leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
