. The use of positive pressure blower when there is a certain regulations, but a lot of consumers have been in accordance with their own unique way, in fact, positive pressure blower use, we must follow the maintenance of the system to be pressurized blower maintenance, today, Xiao Bian will simply introduce the next bar. 1, positive pressure blower must be someone at runtime, personal service. 2, the fan is running if you find fault, we must stop running modular air conditioning units, for maintenance, not sick to run. 3, positive pressure blower repairs must be emphasized first stop off. 4, in addition to the lubricant should be replaced after each overhaul, but under normal circumstances, from March to June change the oil. 5, regular internal fan to clear dust, especially dust on the impeller, dirt and other impurities, in order to prevent corrosion and imbalances. 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 amount of wind gauge relatively large centrifugal fans, axial fans high-pressure than the combined air-conditioning unit manufacturers, and other characteristics can be axially mounted; low noise, low power consumption, efficient wide area, easy to install and 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, directly connected to water-cooled modular and duct air conditioning units, horizontal 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. Combined air-conditioning unit manufacturers _ air handling units (certified) _ modular air conditioning units 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. Air conditioning leader at Watson with the staff warmly welcome all inquiries negotiations to create Watson conditioned a better future.
