The 75 kW Roots blower is an energy-saving gas conveying equipment widely used in the industrial field, and its selection requires comprehensive consideration of multiple factors such as flow rate, pressure, structure, and material.
Main features of a 75 kW Roots blower
1. Energy saving: adopting advanced Roots blower technology, with small airflow pulsation, low noise, and smooth operation. The double bladed wheel structure reduces gas loss during transportation and improves fan efficiency. High quality motors ensure stability and reliability during long-term operation.
2. Widely applicable: Suitable for industries such as chemical, fertilizer, building materials, and environmental protection. In the chemical industry, it can be used to transport various corrosive gases; In the building materials industry, it can be used to transport powdered materials; In the environmental protection industry, it can be used for waste gas treatment, etc.
3. Diverse models: The 75KW fan models covered by the two blade Roots blower include RD series, RE series, RF series, RG series, etc., with a wide range of air volume parameters, such as 31.2m3/min to 292.6m3/min.
4. Flexible configuration: Optional variable frequency motor and variable frequency controller can be used to automatically adjust the power frequency and change the fan speed according to actual production needs, achieving energy-saving and noise reduction.
Key selection points
1. Flow rate and pressure: Select the appropriate fan model based on the required air volume and pressure increase requirements of the system. The margin that flow should have is generally 1.1-1.25 times the flow required by the system; There should be a margin for boosting, usually 1.05 to 1.15 times the system pressure drop.
2. Medium characteristics: Consider factors such as temperature, humidity, and corrosiveness of the conveyed medium, and select appropriate materials and sealing forms. For example, when transporting corrosive gases, fans made of corrosion-resistant materials should be selected.
3. Structural form: Choose a suitable structural form based on installation space and usage requirements, such as direct or belt transmission, dense complete sets of units, or ordinary grouping methods.
4. Economy: Considering the price, operating costs, and maintenance expenses of the fan while meeting the system requirements, choose products with high cost-effectiveness.
Price range
The price of a 75 kW Roots blower varies depending on factors such as brand, model, and configuration. The common price range in the market ranges from tens of thousands to tens of thousands of RMB. The specific price needs to be determined based on factors such as region, supplier, and customization requirements.
Application Cases
1. Cement production: used for vertical kiln blowing, providing combustion supporting air, helping materials fall vertically in the kiln, and achieving clinker firing.
2. Thermal power generation: used for boiler ventilation, providing the necessary air for combustion and improving the thermal efficiency of the boiler.
3. Environmental protection industry: used in exhaust gas treatment systems to provide stable airflow and ensure the normal operation of exhaust gas treatment equipment.
