GXF diagonal flow fan

1、GXF type diagonal flow fan overview

1.1. GXF type diagonal flow fan, its impeller wheel is tapered, import wheel diameter is relatively small, the air flow on the surface of the meridional acceleration, avoids the impeller wheel hub with the guide vane wheel have larger convex platform caused by flow separation, which can obtain high efficiency and low noise fan. As the airflow in the fan flow axial velocity increases, prompted the static pressure gradient decreases, and avoid the air flow out, higher pressure coefficient are obtained.

1.2. The fan according to the number is divided into 16 types of specifications, 300 ~ 300 mm series air volume is 1500 ~ 90000 m3 / h, total pressure is 95 ~ 1500 pa. GXF diagonal flow fan through continuous improvement and development, now can be classified by type points A, B, C, D, E, F six types, wide range of parameters, selection of convenience, to adapt to the requirements of different working conditions. Fan but make it a two-speed motor, motor with double speed motor, realize two speed, can meet the needs of the users to adjust the performance of different point, also can with frequency conversion motor and inverter controller, realize stepless speed regulation, the recommended frequency of the regulating lock in 25 hz ~ 50 hz.

1.3. In order to meet the need of explosion-proof environment, can make explosion-proof fan fan, explosion-proof grade for EXdIIBT4.

1.4. The requirement of the noise in order to adapt to different places, the fan can be with different length of muffler, also can make coated type fan.

2、SWF type mixed flow fan working conditions

Working temperature: - 20 ~ + 40 ℃;

Humidity: < 90%;

Medium term: air (dust content does not exceed 100 mg/m3);

Work power: three-phase, 380 v / 50 hz.

3、SWF type mixed flow fan application

    Fan can be widely used in civil construction, industrial and mining enterprises, hotels, restaurants, museums, stadium and other places of ventilated take a breath, the most suitable for pipeline pressure, air supply and exhaust air and high-rise buildings, the general architecture of ventilated take a breath.

4、SWF type mixed flow fan configuration  

4.1. The standard configuration

The impeller; The motor; Chassis (ram yao current collector, guide vane, inner tube, motor bracket); Bottom of feet.

4.2. Optional and accessories (when ordering specify whether to buy)

    ※Vibration damping device；※Control box；※Net；※Mating flanges.

5、SWF type mixed wind flow machining process

    5.1. Fan impeller for steel wheel hydraulic stretch forming, blade hydroforming after stamping, welding assembly forming blade and hub. The impeller by the dynamic and static balance correction, no greater than G5.6 level balance precision.

    5.2. Outer tube flange flanging are used for spinning, current collector inlets, hydraulic mould.
