The dense Roots blower is a compact gas conveying equipment, and the following is a detailed introduction to it:
1、 Basic Overview
Dense Roots blower refers to a fan in which two or more Roots impellers are installed on the same axis and their external dimensions are standardized. Its working principle is to remove and transport the material through the air gap between two or more synchronously rotating Roots impellers. When the spindle rotates, the space between the impellers will constantly change. Due to the special design of the impellers, gas will be forced to circulate from one impeller to another, thus achieving continuous gas delivery.
2、 Main features
1. Compact structure: The dense Roots blower adopts a compact design, with small volume, light weight, and easy installation and maintenance.
2. High efficiency: Due to the gradual opening line design of the impeller, the overall efficiency is high, which can reduce energy consumption.
3. Low noise: Advanced noise reduction technology is used to reduce the noise of the fan during operation, with minimal impact on the working environment.
4. High pressure boost: Dense Roots blowers have a high pressure boost capability, which can meet gas delivery under different pressure requirements.
5. Low vibration: The rotor has high balance accuracy, small vibration amplitude, and reliable long-term operation.
3、 Performance parameters
The performance parameters of a dense Roots blower mainly include flow rate, boost voltage, motor power, etc. Here are some typical performance parameter ranges:
1. Flow rate: usually between 0.67 and 132 cubic meters per minute, depending on the fan model and pressure.
2. Boosting: It can be adjusted within the range of 9.8~98kPa, and some fans can even achieve higher boosting ranges.
3. Motor power: Depending on the air volume and pressure, the motor power also varies, usually between 0.75 and 280 kW.
4、 Scope of application
Dense Roots blowers are widely used in various occasions that require gas transportation, such as:
1. Electricity: Used for gas transportation in desulfurization, denitrification, dust removal and other systems of power plants.
2. Chemical industry: used for gas stirring, mixing, transportation, etc. in chemical production.
3. Steel smelting: used for assisting combustion and ventilation of equipment such as blast furnaces and converters.
4. Cement: Used for material transportation, ventilation, etc. in cement production.
5. Wastewater treatment: used for aeration, agitation, etc. in wastewater treatment plants.
In addition, dense Roots blowers are widely used in industrial fields such as pneumatic conveying, air separation equipment, waste incineration plants, food processing, and construction casting.
5、 Selection suggestions
When selecting, comprehensive consideration should be given to specific usage requirements and environmental conditions. Here are some selection suggestions:
1. Clear requirements: Firstly, clarify the required performance parameters such as air volume and pressure, as well as factors such as material characteristics and conveying distance.
2. Model selection: Choose the appropriate fan model according to your needs, taking into account factors such as the fan's structural form, transmission method, and sealing type.
3. Consider maintenance: Understand the maintenance cycle and cost of the fan in order to perform appropriate maintenance work during use.
4. Choose a brand: Choose well-known brands and reputable manufacturers to ensure product quality and after-sales service.
In summary, dense Roots blowers have the characteristics of compact structure, high efficiency, low noise, high pressure rise, and low vibration, and are widely used in various gas transportation applications. When selecting, comprehensive consideration should be given to specific needs to ensure the selection of suitable fan models.
