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 Henan air heating units, 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, mobile point if you choose the d curve for maximum efficiency, it would be difficult to achieve the maximum efficiency of mine ventilation air heating units, positive pressure blower, for a model of fan impeller, By the above equation, it is the ratio of 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 according interior dimensions on the wall punched way, it will be more convenient to the heating unit, such as household electricity voltage is 220V, 220V can be customized so that civilian electricity. SWF positive pressure blower with positive pressure blower there a difference? SWF positive pressure blower positive pressure blower with positive pressure blower What's the difference? Effects are the same thing? First, explain to your SWF positive pressure blower with positive pressure blower distinction: SWF positive pressure blower is part of a positive pressure blower, it is a type of air heating unit manufacturers, including positive pressure blower inside the range of models and specifications. Their uses and functions are the same, but the inside of the series is not the same, and their functions are installed in the escape corridor air supply fan. In the case of a fire, it will produce a lot of smoke inside the building as well as carbon monoxide and other toxic gases and block the line of sight, through positive pressure blowers outside pressure fed into the room, blowing through its function to escape by creating Escape the space, indoor smoke can not reach the stairs, it is to increase relief efforts as well as space for people to escape. So SWF positive pressure blower is a positive pressure blower, almost no difference.
