Description

Roots Blower Overview

The Roots blower is a typical positive displacement rotary blower. It delivers gas forcibly through two synchronously counter-rotating figure-8 impellers. It features constant flow, simple structure and oil-free gas supply, widely adopted as low-pressure air source equipment in various industries.

Working Principle

Two sets of impellers inside the casing rotate synchronously in opposite directions, causing periodic volume change of the working chamber. Air is sucked in when the chamber expands and forced out when the chamber shrinks.
There is no internal gas compression inside the unit. Gas is only displaced by impellers, and pressure rise is achieved by pipeline backpressure. At fixed rotating speed, the output flow barely fluctuates with pressure variation, realizing forced gas delivery.

Main Structure

Key components: precision impellers (2-lobe and 3-lobe types), synchronous gears, casing, bearings, shaft seals and lubrication parts.
  • 2-lobe Roots blower: low cost but severe airflow pulsation and high noise;
  • 3-lobe Roots blower: much lower airflow pulsation, vibration and noise, the mainstream model in current market.

Advantages & Disadvantages

Advantages

  1. Constant air flow: Under fixed rotation speed, air volume remains stable regardless of pressure changes.
  2. Easy maintenance: Fewer components, low vibration and long service life with low operation cost.
  3. Clean gas supply: No lubricating oil mixed with airflow to achieve oil-free delivery.
  4. Cost-effective: Far lower purchase price than magnetic levitation blowers, ideal for small and medium-sized factories.
  5. Wide medium adaptability: Able to convey air, inert gas and other media.

Disadvantages

  1. Relatively high operating noise, which requires supporting silencers and sound insulation covers.
  2. Sharp efficiency drop under high pressure, mainly suitable for low and medium pressure conditions.
  3. Obvious heat generation during long continuous operation, requiring effective heat dissipation.

Application Scenarios of Roots Blowers

  1. Sewage & Environmental Treatment
    Used for aeration in biochemical tanks to supply oxygen for microorganisms to degrade organic pollutants in wastewater; also applied for sludge agitation and waste gas collection & transportation.
  2. Pneumatic Conveying Industry
    Convey powdery and granular materials in closed pipelines without dust pollution:
  • Building materials: cement, lime powder transportation
  • Grain & oil: flour, grain particle conveying
  • Energy industry: coal powder, biomass powder delivery
  • Chemical industry: various chemical powder raw materials transfer
  1. Aquaculture
    Oxygen aeration for fish ponds, shrimp ponds and aquaculture greenhouses to increase dissolved oxygen in water and avoid fish/shrimp hypoxia.
  2. Industrial Manufacturing
  • Food industry: raw material dehydration, cooling, air supply for vacuum packaging
  • Mining: underground ventilation, mineral material purging
  • Thermal power plants: coal powder conveying, ash silo fluidization
  • Electroplating & chemical industry: tank liquid stirring, waste gas purging
  1. Vacuum and Other Fields
    Vacuum packaging, vacuum adsorption; industrial waste gas collection and tail gas treatment; aeration for black and odorous river remediation; pulp stirring and paper material conveying in paper mills.
