KRS energy-saving and environmental protection FRP centrifugal fan

I. Uses
The ventilator can be widely used in pharmaceutical and chemical industry, precision electronics, metal processing, PCB circuit board, sewage deodorization, semiconductor manufacturing process, electroplating pickling and other occasions containing acid and alkali components and chemical compositions.
II. Fan types
There are three types of blower: B-belt, C-axis, and D-direct.
III. Structural features
The ZYF fan is mainly composed of impeller, casing, air inlet, casing support frame, belt, pulley, pulley cover, base, relative base, shock absorber, etc.
(1)The impeller is composed of 8 to 36 retroverted wing blades, curved front cover plates and flat plate rear plates.
(2)The fan casing and the impeller are all made of pure glass-reinforced plastic (FRP) material, which has high strength, light weight, not aging, good corrosion resistance, low noise, and anti-static properties.
(3)KRS fans are far more sophisticated than similar fans in terms of material sophistication, overall fan appearance, and stability.
(4)The transported gas must not contain viscous substances, dust and hard particles contained ≤ 150mg/m3, gas temperature ≤ 100 °C, relative humidity ≤ 100%.
(5)The transmission mode can be designed as a belt type, shaft type, direct type transmission, which should be selected on site.
(6)The casing is made of screw pre-injection molding to ensure the strength of the shell.
(7)The interface between the inlet bell and the housing is flat to reduce leakage.
(8)The fan is equipped with inspection holes and cleaning holes for easy inspection and cleaning.
(9)The transmission part consists of a main shaft, a bearing seat, a rolling bearing, a pulley or a coupling.

VI. Comparison of fan efficiency
※ According to the "fan similarity law": the ratio of speed to horsepower has a cubic relationship, so the higher the efficiency, the more energy-efficient.
※ Fans at the same operating point: The higher the efficiency, the lower the speed.
