Which professional boiler Roots blower manufacturer is boiler Roots blower price? Which professional boiler Roots blower manufacturer is boiler Roots blower price? Which professional boiler Roots blower manufacturer is Boiler Roots blower? Price Working Principle of Roots Blower Roots blower is a volumetric fan. The air volume delivered is proportional to the number of revolutions. Every time the three-bladed impeller rotates, three impellers suck and exhaust the gas three times. Compared with the two-bladed type, the gas The pulsation is reduced, the load changes are small, the mechanical strength is high, the noise is low, and the vibration is small. There is a three-blade impeller on the parallel axis. There is always a small gap between the wheel, the inner hole surface of the oval casing and each impeller. Since the impellers rotate in opposite directions at a constant speed, the casing and impeller A certain amount of surrounded gas is transported from the suction side to the discharge side. Each impeller is always in the correct phase by a synchronous gear and does not touch each other. Therefore, it can be driven at high speed without internal lubrication. It has a simple structure, smooth operation, and stable performance. It is suitable for a variety of purposes and has been used in a wide range of applications. field. In short, its working principle is: the moment the top of the rotor opens like an exhaust port, the high-pressure air from the exhaust port flows back into the can and is compressed. This counterflow and compression produces dramatic pressure changes. This pressure change causes the fan noise. Roots blower is a positive displacement rotary blower. Its principle is that when the air enters the fan through the muffler, the two impellers in the casing will maintain a certain gap between each other, and then the Roots blower will drive the constant speed reverse direction through the synchronous gear. Rotate, push the inhaled gas from the inlet to the outlet, and overcome the resistance of the high-pressure gas on the outlet side, and force it out of the unit through the exhaust muffler, safety valve, etc., and finally achieve the purpose of transporting the gas.
From the perspective of use, when the Roots blower fan is started, there is no need to install a valve at the air inlet, while the centrifugal blower must close all the inlet valves and install an energy-saving valve at the air inlet. Furthermore, Roots blowers and centrifugal blowers must adjust the air volume by adjusting the rotation speed. The larger the adjustment range, the centrifugal blower can be adjusted within a small range by adjusting the air inlet valve. One thing to note is that when the centrifugal blower model is selected, the pressure increase is determined and cannot be used with overpressure. During use, if the pressure is found to be low, the fan cannot be used by increasing the motor power. When the pressure originally selected by the blower is not the maximum allowable pressure increase of the blower, the operating pressure of the blower can be increased by increasing the motor power. In addition, from the perspective of performance characteristics, when the pressure becomes smaller, the flow rate of the Roots blower changes very little and has hard exhaust characteristics. When the pressure of the centrifugal blower changes, the flow rate changes greatly. From the price point of view, for small flow blowers, Roots blowers have greater advantages than centrifugal blowers.
