Rotary centrifugal fan blower fan

Difference between centrifugal fans, blower, rotary blower works from several blower comparison: 1, the working principle of centrifugal blower fan impeller drive when the motor is rotated to rotate, the gas between the blades of the impeller also rotates, and under the action of centrifugal force thrown these gases, the gas flow rate is increased, the gas flow in the kinetic energy is converted to static pressure, then pressurized with fluid, so that the static pressure energy is converted to velocity energy and, through the exhaust port exhaust gas, which is formed in the wheel of some of the negative pressure, due to the entrance of negative pressure, so that the outside air at the atmospheric pressure immediately fill in, in the continuous rotation of the impeller continue to discharge and fill the gas, so as to achieve a continuous blast purposes. The same power, air pressure and air flow is generally inversely proportional to the process. The same power, high pressure, air volume will be relatively low, but the wind volume, pressure will be lower, so as to fully utilize the power efficiency of the motor. 2, Roots blower, Roots blower Working Principle: The Heights is a positive displacement blower fan, air volume delivered and the number of revolutions is proportional clover impeller to rotate once every two impellers made three times the suction and discharge, Compared with the second leaf type, gas pulsation is reduced, a small load change, high mechanical strength, low noise, vibration small. In phase two flat line shaft is provided with two clover-type impeller, and always maintain a slight gap between the wheel and oval chassis and each wheel bore surface three, since the impeller uniform rotation in the opposite direction to each other, so that the box and impeller are surrounded by a certain amount of gas delivered to the suction side of the side discharge. Each branch of the impeller always maintain the correct phase from the synchronizing gear, will not touch each other and, therefore, can be high-speed, no internal lubrication, simple structure, stable operation, stable performance, adapt to a variety of uses, it has been used in a wide range of fields. 3, rotary blowers structure and working principle: the blower pressure range: 0.1-0.5kgf / cm2 rotary blowers compact structure, mainly composed of the following six components: motors, air transition, a blower body, the air chamber, the base (and fuel tank) , drip mouth. Blowers biased against the inner cylinder rotor eccentric operation, and the volume change of the rotor blade slot 4 between the air intake, compression, spit. The blower pressure difference in the operation automatic lubrication to drip nozzle inner cylinder was dropped to reduce friction and noise while maintaining the cylinder of gas is not reflux.
