Roots blower Note: 1, the fan should not be installed in places frequented by people, prevent injuries and burns. 2, the fan should not be installed in easy to produce flammable, explosive and corrosive gases in case of fire and poisoning and other accidents. 3, according to the direction of the intake and exhaust ports and maintenance needs, basic face four weeks should leave appropriate leeway. 4, fan blower installation price, should look at the foundation is solid, the surface is smooth, the foundation is above the ground and so on. 5, when the outdoor fan configuration, set anti-canopy. 6, fans at not more than 40 ℃ ambient temperature can be long-term use, more than 40 ℃, should install exhaust fans and other cooling measures to improve the life of the fan. 7, when the conveying air methane gas and other media, the dust content should generally not exceed 100mg / m3. How it works: positive displacement blower fan, air volume delivered is proportional to the number of revolutions, clover type impeller rotates once every two impellers by three times the suction, exhaust blower phone manufacturers, compared with two leaf type gas pulsation is reduced, small changes in load, high mechanical strength, low noise, vibration small. In the two-phase line shaft flat has two clover-type impeller, and always maintain a slight gap between the wheel and the oval hole in the chassis side and all three impellers, due to uniform rotation of the impeller opposite directions, so that the box and the impeller is surrounded by a certain amount of gas delivered to the suction side of the discharge side. Each branch by synchronizing gear wheel always maintain the correct phase blower wholesale prices, does not appear to touch each other and, therefore, can be high-speed, no internal lubrication blower, and simple structure, stable operation, stable performance, adapt more such use has been applied to a wide range of fields.
