The working principle is different. The centrifugal fan uses a curved fan blade, and the gas is thrown to the casing by centrifugal force, while the Roots fan uses two figure-8 fan blades. The gap between them is very small. Squeeze, squeeze the gas to the air outlet. Due to different working principles, generally their working pressures are different, the outlet pressure of the Roots fan is relatively high, while the centrifugal fan is relatively small.
The air volume is different. Generally, Roots fans are used in places where the air volume requirements are not large but the pressure requirements are high, while the centrifugal fans are used in places where the pressure requirements are low and the air volume requirements are large.
The manufacturing precision is different. The Roots blower requires high precision and strict assembly requirements, while the centrifugal blower is relatively loose. Of course there are some minor differences.
Both the Roots blower and the screw blower are positive displacement blowers. If they need to perform PK, it can be simply attributed to the difference in the compression principle. The advantages of energy saving, stability and low noise of the screw blower are more prominent.
During the operation and air delivery of the Roots blower, the volume of the cavity between the rotors does not change. The pressure comes from forcing a large amount of air into an external cavity with a relatively small volume, such as a pipeline or an air storage tank. , the density of the air in the outer cavity continues to increase, resulting in pressure, commonly referred to as "external compression". The Roots blower has a simple structure, forced air supply (the air supply volume is not affected by the exhaust pressure), and does not generate pressure by itself.
The working principle of the screw blower is somewhat different from that of the Roots blower. The air is also sucked in and then discharged. When inhaling, the cavity between the screw and the screw is large. With the rotation of the screw rotor, the cavity The volume will gradually become smaller, and when the gas is exhausted, the volume of the cavity will become very small. That is to say, during the rotation process, it is equivalent to compressing 2m³ of gas into 1m³ of gas, and the pressure will increase accordingly, that is to say, the increase in pressure does not come from the peripheral pipe network, but from the host cavity. Changes in the internal volume, also known as internal compression.
The complete Roots blower also includes a base, a motor, an inlet muffler, an outlet muffler, a check valve, a pressure gauge, a V-belt, a pressure relief valve, an elastic joint, a motor pulley, a belt cover, and an anchor bolt.
Then, what spare parts are mainly needed for the Roots blower, which are consumables, and need to be replaced regularly. Now I will share with you. The main spare parts and wearing parts of the Roots blower mainly include gears, bearings, V-belts, filter elements (filter cotton) of air filters, etc.
<p>Roots blowers are used to generate constant airflows that are independent of discharge pressure conditions. Root blower applications are limited to low and medium pressure and vacuum processes, and can be used to provide small to large airflow rates.</p>
<p>The Roots supercharger works through a pair of rotors that blow air at a high speed into the intake port. As the port then contains a greater quantity of air, it becomes compressed. In turn, this enables a higher quantity of fuel to be injected into the combustion chamber (and thus greater power to be generated).</p>
<p>Operating principle of a Roots pump is a rotary positive-displacement type of pump where<strong> </strong>two symmetrically-shaped impellers rotate inside the pump casing past each other in close proximity. The two rotors have a cross section resembling approximately the shape of a figure 8 and are synchronized by a toothed gear.</p>
