Positive pressure blower installation than the transfer value is kind of how? Without positive pressure type blower, having different heating unit than the diameter D Inner air, 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 Henan air heating units, and is also very simple. Direct carrying pressurized air circulation blower when installing heating units, installed in the pipe or equipment can be carried out anytime fan speed measurement. 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 maximum efficiency ventilator, positive pressure blower, for a model of fan impeller, by the equation, it is the ratio of the diameter and speed coefficient. Positive pressure blower impeller located below the model d curve heating unit, 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. SWF Francis fan application meridional acceleration method and "quasi-ternary" flow theory of design, the use of linear-shaped outer cylinder, cone wheel, twist the wing blade structural forms. Pressure compared with the same machine number of high axial fans, air volume compared with the same machine number large centrifugal fan. High efficiency, compact structure, low noise, small size, easy installation, etc., widely used in hotels, restaurants, shopping malls, office buildings, stadiums and other senior civil through the exhaust pipe pressurized air supply and ventilation of industrial and mining enterprises to change gas properties. Wherein the two-speed fan can be adjusted desired amount of wind, air pressure according to the use conditions required by the shift. A, SWF SWF series of positive pressure blower Overview series of positive pressure blower has the same number of the machine relatively large amount of wind centrifugal fan, air pressure higher than the axial fan, and other characteristics can be axially mounted; low noise, low power consumption, efficient wide area installation easy to use than the centrifugal fan, reliable operation. Two, SWF series of positive pressure blower Features: 1, compact, easy installation, reliable operation; The fan than axial or centrifugal small size in the case of the same amount of wind, air pressure, and directly connected to the duct, horizontal installation or vertical installation, easy operation features. 2, low noise: positive pressure blower housing is specially designed to greatly reduce the outflow of noise. In the unit amount of wind, air pressure unit operating conditions, than A sound level can be reduced 2-3dB (A), while in the case of low speed, can obtain higher fan pressure. KJZ mine heating unit (Figure), Ningxia air heating units, heating units provided by the Texas Huaxin air-conditioning plant. Texas Watson conditioning plant (www.wchuaxin.com) (www.wchuaxin.com) is a professional "cooler, hot water heaters, centrifugal air curtain, finned tube radiators, mine heating unit," the the company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, "Lu Peng" brand has a good reputation. We adhere to the "service first, customer first" principle, so air conditioning Watson won the trust of customers in all heat, refrigeration and air conditioning equipment, and establish a good corporate image.
