Companies to strict production control procedures as well as excellent service awaits you, to guide, to discuss cooperation! Exhaust fan impeller is made of steel wheels hydraulic stretch forming exhaust fan Price, hydroforming press the blade exhaust fan, blades and hub assembly welding forming. Technology Second, the HTF fire exhaust fan impeller static and dynamic balance correction exhaust fan installed, balance accuracy is not greater than G5.6 levels. Process Third, and finally we would also like to learn about the production process is HTF fire exhaust fan is spinning from the outer cylinder flange XGF fire temperature exhaust fan -HTF (B) series fire temperature exhaust is with the overall flanging Francis fan smoke multi-objective optimization using CAD software design, matching molded twisted wing Francis impeller, totally enclosed motor built supply temperature exhaust fan, arranged a special motor cooling system. Use two-speed motor direct-drive, to one machine (that usually send row when high-temperature exhaust ventilation and firefighting) Tongcheng Huainan pressure blower, remote automatic control media such provision exhaust fan disposed after use electronic control box temperature range. Exhaust fan is building ventilation exhaust system in a very important product. For the safety of our lives play a significant role. Fire exhaust fan is energy saving machines. Pressurization according to its performance excellent Tongcheng Huainan fan, high temperature, high efficiency, small footprint, easy installation. Before commissioning fire exhaust fan installed after the application or operation of the process, such as found irregularities in Tongcheng Huainan pressure blower should be checked continuously. Except after each overhaul, replace part of the exhaust fan parts, it should also regularly commissioning. When inspection found little fault exhaust air box, it is timely to identify the reasons, try to eliminate or deal with, such as small fault can not be eliminated Tongcheng Huainan pressure blower, or the great failure, should be checked immediately. Found the amount of traffic, does not meet the requirements, or a short time requires a smaller flow exhaust fan, can be used to adjust the throttle device.
