Roots blower and centrifugal fan working principle difference

Roots blower and centrifugal fan working principle difference: 1, the centrifugal blower works When the motor rotates to drive the fan impeller rotation, the impeller blades also rotate between the gas, and the centrifugal force thrown out of these gases, gas The flow rate increases so that the gas in the flow of kinetic energy into static pressure energy, and then with the fluid pressure, the static pressure energy can be converted to speed, exhaust through the exhaust gas, and in the middle of the impeller to form a certain Negative pressure, as the entrance was negative pressure, so that the external air immediately under the action of atmospheric pressure into the continuous rotation of the impeller continuous discharge and fill gas, so as to achieve the purpose of continuous blasting. Under the same power, wind pressure and air flow in the general inverse ratio. The same power, the wind pressure is high, the air volume will be relatively low, while the air volume, wind pressure will be lower, so as to take full advantage of motor efficiency. 2, Roots blower, Roots blower works How it works: Roots blower is a positive displacement fan, the delivery of air flow and the number of revolutions, trilobate impeller for each rotation by the two impeller 3 suction, exhaust , Compared with the two-leaf type, less gas pulsation, small load changes, high mechanical strength, low noise, vibration is small. In the two parallel axis is equipped with two trilobate impeller, the wheel and the oval-shaped hole in the chassis and the impeller always maintain a slight gap between the three, as the impeller rotation in opposite directions for uniform rotation, so that the box And a certain amount of gas surrounded by the impeller from the suction side to the discharge side. Each impeller is always maintained by the synchronous gear phase correct, will not touch each other phenomenon, which can be high-speed, without internal lubrication, and simple structure, stable operation, stable performance, to adapt to a variety of uses, has been used in a wide range of field. Oasis Roots blower introduction and absorption of clover Roots blower advanced technology, the use of advanced CAD-aided design, research and development and professional Seiko production of high quality, low noise, a new generation of energy efficient products, the product has a reasonable structure, small size, High pressure, high efficiency, large air volume, low noise, stable operation, excellent performance, long life, easy maintenance and so on. Its flow rate from 0.8m3 / min-180m3 / min, boost 9.8kpa-98.8kpa, a total of 11 models, more than 80 kinds of specifications, has been widely used in sewage treatment, aquaculture, pneumatic conveying, vacuum packaging, coal washing, Combustion, booster, casting, mining, metallurgy, chemicals, light industry, building materials, electricity, flour, sandblasting, vacuum and other fields.
