DWT roof fan, air conditioning Heng Hing diagram, DWT roof fan Description

Fans device body temperature than normal, the following main reasons: The first: the lack of phase motion or wiring error; second: the system resistance is too large or the optional fan motor overload caused by an irrational, reason the pipe network resistance coefficient is too large or pipe coefficient Valve does not open; third: the power pressure is low; fourth: motor bearing damage, with a small gap, does not meet the requirements. Fan body too is actually a more serious problem, especially for axial fans, roof fan these have important mechanical equipment, there is a little unusual place, it will affect the normal operation of the machine, it should be attention. 1. Type specifications, a wide range of applications: according to the different requirements of air volume to applications, pressure and noise, use the following types of fans: a, Axial roof fan: code for DWT-I type, with air volume pressure than the centrifugal fan characteristics. At the same time according to user requirements can also be designed reversible bi-directional rotation, with both positive and negative characteristics equivalent type situation. b, Centrifugal roof fan: code for DWT-Ⅱ type, DWT-Ⅲ type two kinds of patterns for smaller air volume and pressure requires high; c, no motor roof fan: code for DWT-Ⅳ type for steel roof of the new century fan first green product. 2. The high efficiency, low noise fan system using advanced CAD Series software, the multi-objective optimization design and development. This series of fans in 1200.1400.1500.1600.2000. And 2400mm diameter fan with the same values ??of different speeds, different angles to change several volume. Pressure way to meet the needs of different use conditions, to match fan and systems to facilitate energy savings and noise reduction; 3. light. High Strength. Corrosion; air fan impeller according to work different corrosive media and using different materials, respectively, ABS (plastic) FRP (GRP) and aluminum sheet production, the pressure for high fan speed greater centrifugal fan, impeller surface is galvanized plus special spray corrosion treatment, not only reduce the machine weight and has good corrosion resistance;
