Roots dresser blower

Roots blower is a volumetric blower with impeller end face and front and rear end covers of the fan. The principle is a rotary compressor that uses two blade-shaped rotors to move relative to each other in the cylinder to compress and transport gas. This type of blower has a simple structure and is easy to manufacture. It is widely used in aquaculture oxygenation, sewage treatment aeration, cement transportation, and is more suitable for gas transportation and pressurization systems in low-pressure situations. It can also be used as a vacuum pump.

Roots blower working principle

Roots blower is a type of positive displacement fan. It has two three-bladed impellers that rotate relatively in a space sealed by the casing and wall panels. Since each impeller adopts an involute or epicycloid envelope Line, the three blades of each impeller are exactly the same, and the two impellers are also exactly the same, which greatly reduces the difficulty of processing. The impeller is processed using CNC equipment, which ensures that when the center distance between the two impellers remains unchanged, no matter where the two impellers rotate, a certain minimum gap can be maintained, thereby ensuring that gas leakage is within the allowable range.

What is the difference between a Roots blower and a blower?

• Roots blowers and blowers both belong to the category of centrifugal fans, but they are very different in structure and working principle:
• Structural differences
  The unique structure of the Roots blower is composed of an outer rotor and an inner rotor. The two rotors mesh with each other to produce the effect of gas compression and transportation. This structure has the advantages of small size, low noise, no vibration and no oil pollution.
  The blower generates airflow through the rotation of the impeller in the casing, and then compresses and transports the airflow through the action of the air guide assembly. The blower has the advantages of compact structure, low energy consumption and long service life.
• Differences in working principles
  Roots blower generates gas compression and transportation effects in the casing through the mutual meshing of two rotors. Roots blowers usually rotate at very high speeds, so they require specialized care and maintenance when working.
  The blower generates airflow through the rotation of the impeller, and then compresses and transports the airflow through the cooperation of the guide components. The working speed of the blower is usually low and the operation is simple, so you need to pay attention to correct operation and maintenance during use.

What are the benefits of a Roots blower?

• High efficiency: Due to its internal sealing structure, the Roots blower can avoid gas leakage while transporting air flow, thereby achieving efficient and stable gas transport. Moreover, its operation efficiency is high and it can save certain costs in terms of energy consumption.
• Low noise: Compared with other types of blowers, Roots blowers have very low noise. This is due to the special noise elimination technology used in its design, which can ensure that the noise during operation is controlled within a reasonable range. It is especially suitable for Noise-sensitive work environment.
• Large displacement: Roots blowers can provide a large amount of gas transportation capacity. In the industrial production process, a large amount of gas is often needed to drive production equipment. At this time, Roots blowers can take advantage of their large displacement characteristics, thus better to meet the needs of the production process.
• Wear resistance: The internal structure of the Roots blower is reasonably designed, and there will be no friction or collision between the master rotor and the slave rotor, thereby avoiding wear and tear of machine parts. At the same time, in terms of manufacturing process, wear-resistant and corrosion-resistant materials are used to ensure the long-term use of the machine.
• Strong adaptability: Roots blowers can adapt to different working conditions such as various gases, pressures, flows, etc. Roots blowers can adapt to the different media such as high pressure, high temperature, corrosion, viscosity, etc. that are often encountered in industrial production. able to meet needs.
