- Our company absorbs the domestic and foreign similar products technology and ameliorates it. And designed and produced the DWF series external-rotor motor straight association AC air blower is suitable for each kind central, the cabinet type air conditioning unit, the cold hot curtain, changes the amount of wind air-conditioner, the wind engine case, the building ventilates as well as the movie profession xenon lamp photo source radiation and the automobile dries the japanning room to ventilate situations and so on air change.
- Because it used outside the rotor electrical machinery to drive wind wheel's advanced structure directly, thus had the big amount of wind , few consumed the electricity, artistic outlook, easy installation and so on merits.Compared with the similar products, the noise approximately lower 2-5dB, the vibration velocity is smaller than 1.8mm/s, the weight lighter approximately 16%.
- Our company technical force is abundant, the craft is advanced, and the inspect method is complete. It is strictly according to the international standard IS09001 production, the quality of product stable and reliable.
the DWF series air blower is mainly composed of four parts: <1>Outside rotor electric motor <2>Wind wheel <3>Volute <4>Collection solar halo 1. The volute select the high quality cold rolling steel plate either the pot galvanize steel plate knee bend weld the system or use nip the shape of the mouth type manufacture. Its line is the logarithmic spiral curve; the lift-drag ratio is good. 2. The air blower air outlet may 0°, 90°, 180°, 270° four kind of position installments, like the following chart. 3. Before the impeller central disk, side the plate, the curved circular arc leaf blade is the ramming formation, the impeller assembly uses rolls the rivet. The impeller transient equilibrium quality rank is the G5.6 level. 4. The main axle use the high quality carbon steel to make and to pass through the quenching and tempering, phosphorization rust prevention processing, the safety performance is good. 5. The inlet use the high quality steel plate after the spinning formation, guaranteed that the air enters the impeller to import the section evenly, reduces the flowing to lose greatly, raises impeller's efficiency. 6. The air blower uses outside parts of rotor low noise three-phase asynchronous motor. This electrical machinery has the axis to be fixed, outer covering revolving characteristic. The impeller installs in the electrical machinery outer covering, revolves the direct drive by the electrical machinery outer covering. This electrical machinery may use the three-phase pressure regulator; the controllable fine jade pressure regulator, the frequency changer ,the stepless speed regulation and so on methods, adapts the system load changeable request.
