root blower vacuum pump

• 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.

What is the difference between Roots blower and vacuum pump?

• The main difference between Roots blowers and Roots vacuum pumps is that although their uses and working principles are similar, the specific application scenarios and exhaust methods are different. ‌
• ‌Different purposes‌: Roots blower is usually used to transport low-pressure gas and gas boosting, and is a kind of wind conveying mechanical equipment; Roots vacuum pump is used to transport gas to high vacuum, and is a kind of vacuum pump.
• Working principle‌: The working principles of the two are basically the same. They both pass through two intermeshing impellers. After the inhaled gas is compressed and transmitted by the impellers, the pressure increases, and then it is discharged from the air outlet. Specifically, the Roots blower increases the pressure of the gas through the compression and transmission of the impeller, and then discharges it from the air outlet; while the Roots vacuum pump uses the operation of the impeller to cause the gas to flow into the cavity from the air inlet and undergo multiple compressions. Finally, it is discharged to achieve the purpose of increasing the vacuum degree.
• ‌Exhaust method‌: Roots blower discharges gas directly through the air outlet; Roots vacuum pump needs to discharge gas through other forms of diffusers, molecular pumps, etc.
• In general, Roots vacuum pump is a device used for vacuum conveying and vacuum degree improvement, while Roots blower is a device used to convey low-pressure gas and pressurized gas. The basic principles of the two are the same, but in specific applications and There is a difference in the exhaust method.

How does a Roots vacuum pump work?

• roots vacuum pump 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.
