The exhaust fan is also called the side flow blower, centrifugal blower, small blower, is a kind of general air source for blowing or inspiration, usually used for the inspiration of mechanical equipment, as the name implies, also called the exhaust fan.
It is composed of rotor with impeller, housing, coupling, bearing, fan, lubrication system, motor, air cooling system, etc. When the motor drives the impeller to rotate, the air enters from the intakes on both sides and rotates with the impeller. Under the action of centrifugal force, the air is thrown from the center of the impeller to the edge, flows into the volute at a high speed, and flows out from the volute to the exhaust outlet. At this time, the fan forms a certain vacuum degree (negative pressure) at the inlet. The air enters the fan through the material surface, bellows, dust removal pipes and multi-pipe dust remover on the trolley. Due to the continuous rotation of the impeller, the flue gas of the inlet constantly flows out to the exhaust pipe through the flow path volute between the blades, so that the sintering process can be carried out.
Exhaust fan from the ventilation principle, divided into high, medium, low, negative pressure four, negative pressure fan series products are commonly used CAD/CAM design, with low noise, low power consumption, large air volume, stable operation, long life, high efficiency, and has the shutter automatic opening, closing system, to achieve waterproof, dustproof, beautiful characteristics. The negative pressure suction fan has a wide range of uses: the negative pressure suction fan is installed outside the workshop window, and generally chooses the lower tuyere and the outward draught to extract the odor gas; Basically all the places that need ventilation can be used.
Used with wet curtain
Used for workshop cooling in hot summer, no matter how hot your workshop is, the wet curtain - negative pressure fan system can make your workshop temperature down to about 30℃, and there is a certain humidity.
Range of application
A, suitable for high temperature or odor workshop: such as heat treatment plant, casting factory, plastic factory, aluminum factory, shoe factory, leather factory, electroplating factory, various chemical plants. B, suitable for employee-intensive enterprises: such as garment factories, various assembly workshops, Internet cafes.
C, suitable for horticulture greenhouse ventilation cooling, livestock pasture cooling.
D. It is especially suitable for places that need cooling and certain humidity. Such as cotton mill, wool mill, hemp mill, weaving mill, chemical fiber mill, warp knitting factory, adding ammunition factory, knitting factory, silk weaving factory, hosiery factory and other kinds of textile factory.
E. Applicable to warehousing and logistics
F, suitable for smoky, hot smell kitchen and dining hall.
