The 110kW Roots blower is a type of Roots blower with a power of 110 kilowatts, belonging to a type of positive displacement fan, widely used in the industrial field. The following provides a detailed introduction from the aspects of working principle, performance characteristics, application scenarios, and selection considerations:
1、 Working principle
The 110kW Roots blower rotates in the opposite direction at a constant speed inside the casing through two three bladed impellers, creating a vacuum at the air inlet. Air is drawn in and compressed before being discharged from the exhaust outlet. Its core features include:
1. Forced air supply: By rotating the impeller, gas is forcefully transported with a stable and continuous air volume.
2. No internal compression: Gas does not undergo compression during transportation and only forms pressure at the exhaust port.
3. Low pulsation: The three bladed impeller design ensures minimal airflow pulsation and smooth operation.
2、 Performance characteristics
1. Energy saving: Adopting optimized impeller design, low energy consumption and high efficiency.
2. Compact structure: small volume, small footprint, easy to install and maintain.
3. Stable operation: The impeller is precision manufactured, with low vibration, low noise, and long service life.
4. Strong adaptability: It can transport clean air, coal gas, natural gas and other gases, suitable for various working conditions.
3、 Application scenarios
1. Wastewater treatment: used for oxygen supply in aeration tanks to promote microbial decomposition of organic matter.
2. Aquaculture: Adding oxygen to the aquaculture pond to increase the dissolved oxygen content in the water.
3. Pneumatic conveying: Conveying powder and granular materials such as cement, flour, coal powder, etc.
4. Chemical industry: used for gas transportation and pressurization, such as hydrogen, nitrogen, etc.
5. Environmental protection field: dust removal, desulfurization, denitrification, reducing environmental pollution.
4、 Selection precautions
1. Air volume and pressure: Determine the air volume and pressure parameters based on system requirements and select the appropriate model.
2. Medium characteristics: Consider the temperature, humidity, corrosiveness, etc. of the transported gas, and select appropriate materials and sealing forms.
3. Environmental requirements: Select the protection level based on the installation environment (such as temperature, humidity, dust, etc.).
4. Brand and after-sales service: Choose well-known brands to ensure product quality and after-sales service.

SR200HB 68.6-98.0 45.2-56.8 high pressure, suitable for deepwater oxygenation
6、 Market price reference
The price of a 110kW Roots blower varies depending on factors such as brand, model, and configuration, with a rough range as follows:
1. Economic type: about 26000-58000 yuan
2. Mid to high end model: approximately 65000 to 78000 yuan
3. Customized Type: Quotation based on specific needs
7、 Maintenance and upkeep
1. Regular inspection: Check parameters such as oil level, temperature, vibration, etc. to ensure the normal operation of the equipment.
2. Lubrication management: Regularly replace lubricating oil to maintain good lubrication of gears and bearings.
3. Cleaning and maintenance: Regularly clean the air inlet and filter to prevent dust and impurities from entering.
4. Professional maintenance: In the event of a malfunction, promptly contact professional personnel for repair.
