Roots blower 7.5kw is a type of Roots blower with specific power. The following is a detailed introduction to it:
1、 Basic concepts and principles
Roots blower belongs to positive displacement blower, and its working principle is a rotary compressor that compresses and delivers gas by using two blade shaped rotors to move relative to each other in the cylinder. This type of fan has a simple structure, is easy to manufacture, and is widely used in multiple fields.
2、 Main features
1. Moderate power: The 7.5kw power makes it suitable for various medium-sized gas transportation and pressurization needs.
2. Three blade rotor structure: Adopting a three blade rotor design, it has the advantages of smaller air pulsation, lower noise, and smoother operation compared to a two blade rotor.
3. High volumetric efficiency: The fan has a high utilization rate of volume and high volumetric efficiency, which can meet the needs of different users and purposes.
4. Compact structure: The overall structure is compact, with flexible and versatile installation methods, making it easy to install and use in different situations.
3、 Scope of application
Roots blower 7.5kw is widely used in the following fields:
1. Aquaculture: Used as an aerator to provide sufficient oxygen for water bodies such as fish ponds.
2. Wastewater treatment: Used in the aeration system of wastewater treatment plants to improve the efficiency of wastewater treatment.
3. Pneumatic conveying: provides stable airflow support during the conveying process of materials such as cement and grain.
4. Other fields: It can also be used for gas transmission and pressurization systems in industries such as petrochemicals, building materials, electricity, smelting, and fertilizers.
4、 Performance parameters
The main performance parameters of the 7.5kw Roots blower include:
1. Power: 7.5kw
2. Noise: usually around 70-80db (specific noise levels may vary depending on different brands and models).
3. Blade diameter: generally around 173mm (specific dimensions may vary depending on different brands and models).
4. Number of leaves: Three leaves.
5. Airflow: Depending on the specific model and application scenario, the airflow may vary, but it can generally meet the needs of medium scale gas transportation.
6. Wind pressure: It has the ability to withstand wind pressure and is suitable for the transportation and pressurization of medium pressure gases.
5、 Selection and installation suggestions
1. Selection suggestion: When choosing a 7.5kw Roots blower, attention should be paid to factors such as brand, model, performance parameters, and user evaluation. Choosing well-known brands and high-quality models of fans can ensure their stable performance and reliable quality.
2. Installation suggestion: The Roots blower 7.5kw should be fixed on the ground. During installation, a pit should be excavated at the corresponding position according to the size of the blower and anchor bolts should be embedded. Then, the blower should be connected with bolts and nuts, and the pit should be filled with cement concrete to fix the blower. During the installation process, attention should be paid to the coordination between the fan and the surrounding environment, as well as details such as whether the connection parts of the fan inlet and outlet are fastened.
In summary, the Roots blower 7.5kw is a gas conveying equipment with stable performance, compact structure, and wide applicability. When selecting and installing, attention should be paid to its performance parameters and installation details to ensure that it can operate normally and smoothly.
