The Roots blower used in the grain suction machine is a key equipment that achieves the suction and transportation of grain by generating negative pressure. The following is a detailed introduction and selection suggestions for Roots blowers used in grain suction machines:

1、 Introduction to Roots blower
Roots blower is a fan equipment based on the non-contact screw working principle. Its working principle is mainly achieved by two or more continuously rotating impellers meshing with each other, so that gas is sucked in from the suction port and expands in the suction chamber, and then blown out, generating a continuous airflow. This continuous airflow can generate negative pressure, thereby achieving the transportation of materials. In the grain suction machine, the negative pressure generated by the Roots blower can suck grain into the machine from the suction port, separate impurities through the separator, and output the grain to the destination.
2、 Suggestion for selection of Roots blower
1. Understand the basic parameters:
Airflow: The gas flow rate through a Roots blower per unit time, usually measured in cubic meters per hour. The required air volume for different grain processing equipment may vary, so when selecting a Roots blower, specific calculations need to be made based on actual production needs.
Pressure: The outlet pressure of a Roots blower, also known as the head of the blower. In grain processing, some places with high environmental requirements require the selection of Roots blowers with high head.
Rotational speed: The number of revolutions of the active shaft of a Roots blower per unit time, transmitted to the active shaft through gears by an electric motor. The rotational speed will affect the gas flow rate and pressure of the fan.
2. Consider operational stability:
The grain processing technology generally requires long-term continuous operation, so it is necessary to choose Roots blowers with reasonable structural design, excellent manufacturing technology, and high-quality material selection to ensure their stable and reliable operation.
3. Pay attention to energy consumption issues:
Energy consumption plays an important role in grain processing, and choosing Roots blowers with high energy efficiency and low energy consumption can effectively save energy costs. You can view the energy efficiency label of the product and compare the energy consumption indicators of different models for evaluation.
4. Consider price factors:
The prices of Roots blowers of different brands and models vary greatly. You can search online to learn about prices, performance, and other information of different brands, compare quotes from various manufacturers, and make choices based on your own needs and budget.
5. Understand after-sales service:
Good after-sales service is an important guarantee for ensuring the long-term stable operation of equipment. When choosing a Roots blower, it is important to understand the manufacturer's after-sales service policy, including maintenance, technical support, and other aspects.
In summary, selecting a Roots blower suitable for use in grain suction machines requires comprehensive consideration from multiple aspects. By understanding basic parameters, considering operational stability, paying attention to energy consumption issues, considering price factors, and understanding after-sales service, it is possible to ensure the purchase of high-performance and reliable Roots blowers to meet the needs of grain processing and production.
