What is the construction and working of roots blower?

  • Roots blower structure
  • Roots blower consists of five parts: casing, wall board, impeller, oil tank and muffler.
  • Casing: mainly plays the role of supporting (wall boards, impellers, mufflers) and fixing.
  • casing
  • Wall board: mainly used to connect the casing and impeller, support the rotation of the impeller, and provide end-face sealing.
  • Impeller: It is the rotating part of the Roots blower, divided into two blades and three blades. However, due to the many advantages of three blades, such as smaller air pulsation, lower noise, and smoother operation than two blades, it has gradually replaced the two-blade Roots blower.
  • impeller
  • Oil tank: Mainly used to store lubricating oil used to lubricate gears and bearings.
  • Oil tank
  • Muffler: used to reduce the noise caused by air flow pulsation when the Roots blower enters and exits.

Root blower working principle

  • The working principle of Roots blower can be simply summarized into the following steps:
  • 1.Suction stage: When the rotor rotates, the volume of the chamber gradually increases, forming a low-pressure area.This low-pressure area attracts outside air into the chamber.
  • 2.Compression stage: As the rotor continues to rotate, the volume of the chamber gradually decreases.This process causes the air to become compressed, increasing its pressure.
  • 3.Exhaust stage: When the volume of the chamber reaches the minimum value, the compressed air will be discharged from the chamber.At this time, the rotation of the rotor will increase the volume of the chamber again to prepare for the next round of suction.
  • By repeating the above steps, the Roots blower can continuously suck in, compress and discharge air.This working principle enables Roots blowers to produce high-pressure, high-flow airflow.

    What is the difference between a blower fan and a regular fan?

    • The difference between blower and fan
    • Blowers and fans are similar in appearance, but the way they generate wind is different. A blower drives an impeller to generate airflow through the rotation of a motor, while a fan blows air through the rotation of blades.
    • Applicable scenarios for blowers and fans
    • The air volume of the blower is large, but the noise is also large. It is suitable for scenes that require large air volume, such as factories, ships, and other large space scenes, but it is not suitable for home use. Fans are lighter and less noisy, and are suitable for use in small-area scenarios such as homes and offices.
    • Advantages and disadvantages of blowers and fans
    • The advantages and disadvantages of the two are relatively obvious. Although the blower has a large air volume, it is noisy and large in size, making it inconvenient to carry. The fan is small and portable, but the air volume is relatively small, making it suitable for use in a comfortable environment. In actual use, the choice should be based on actual needs.

                roots blower

                What is the benefit of a Roots blower?
                The advantages of Roots blower include simple structure, high efficiency, high stability, wide application range, no lubrication, no oil pollution of gas, volumetric operation, small mechanical friction, long service life, etc.
                The main advantages of Roots blowers can be summarized as follows:

                  • ‌Simple structure‌: The structure of the Roots blower is relatively simple, including the main components such as the head, motor, and base, which makes its manufacturing and maintenance relatively easy.
                  • ‌High efficiency‌: Roots blower has high transmission efficiency and low energy consumption, and can compress and transport gas efficiently.
                  • High stability‌: Due to its simple structure and good design, the Roots blower has small vibration and low noise during operation, and has high stability.
                  • ‌Wide range of applications‌: Roots blowers are suitable for a variety of gas transportation scenarios, including compressed air, coal gas, oxygen, hydrogen, etc., and are widely used in petrochemical, building materials, electric power, smelting, fertilizer and other industries.
                  • ‌No lubrication, no oil pollution in gas‌: The impeller of Roots blower has no friction when running in the body, so no lubrication is needed, and the discharged gas is clean and does not contain oil pollution.
                  • Volume operation, wide pressure range‌: Roots blower is a volume operation type. As the pressure changes, the flow rate changes very little, but the flow rate can be adjusted by changing the rotation speed to adapt to different needs.
                  • ‌Small mechanical friction and long service life‌: Due to the design of the Roots blower, the mechanical friction loss is very small, and the contact between the bearing and the gear pair reduces wear, making it long service life.
                  • ‌Balance verification, stable operation‌: The rotor of the Roots blower has been statically and dynamically balanced to ensure that it is very stable and has little vibration during operation.

                  How does a Roots style blower work?
                  The working principle of Roots blower can be simply summarized into the following steps:

                  • Suction stage: When the rotor rotates, the volume of the chamber gradually increases, forming a low-pressure area.This low-pressure area attracts outside air into the chamber.
                  • Compression stage: As the rotor continues to rotate, the volume of the chamber gradually decreases.This process causes the air to become compressed, increasing its pressure.
                  • Exhaust stage: When the volume of the chamber reaches the minimum value, the compressed air will be discharged from the chamber.At this time, the rotation of the rotor will increase the volume of the chamber again to prepare for the next round of suction.

                  What type of pump is a Roots blower?
                  ‌Roots blower is a positive displacement pump. ‌
                  Roots blower, also known as Roots blower, is a positive displacement blower. Its working principle is based on the relative movement of two blade-shaped rotors in the cylinder to compress and transport gas.
                  This kind of fan has a simple structure and is easy to manufacture. It is suitable for gas transportation and pressurization systems in low-pressure situations, and can also be used as a vacuum pump.
                  The design and structure of the Roots blower ensure that it can effectively increase the pressure and flow of gas, and at the same time achieve precise control of gas flow and pressure by adjusting the rotation speed and angle of the impeller.
                  This type of pump is popular for its unique operating mechanism and wide range of applications, especially where stable air flow and pressure are required.
