A ventilation cooling: As sunlight buildings, machinery and equipment, such as body heat resulting in the need ventilated place higher than the outdoor temperature. Suction fan of indoor heat can be quickly discharged, so that temperature and the outside temperature was flat farming fan wholesale price, not the workshop temperature. Second, the air flow away body heat, air flow to accelerate the evaporation of sweat and the heat absorbed by the body, thus allowing the body to feel cool, and natural, like the wind cool. Third, the only negative pressure ventilation fan cooling effect, there is no cooling function, the body cool feeling. Suction fan can lower the temperature to say how many are ignorant. Four, and the curtain with the use of farming fans, the hottest time of the summer workshop temperature can be controlled within 28 degrees Celsius. But the human body can be compared to the air-conditioned cool feeling farming fan manufacturers, facing the curtain a little longer people will feel cold and can not stand. Centrifugal fans transmission parts wear is often seen equipment problems, including blower bearing position, bearing chamber wear, blower shaft bearings bit wear. Centrifugal fan for the failure of traditional repair methods are welding, thermal spraying, brush crossing, etc., but have certain drawbacks: high temperature welding thermal stress generated can not be completely eliminated, could easily lead to material damage, resulting in part appears bent or broken; The coating thickness is restricted by the electric brush, easy to peel off, and the above two methods are used to repair metal metal, can not change the "hard on hard" with the relationship, under the combined effect of each force will still cause the drum plastic bag wear again.
