Roots blower

Good sealing performance: Roots blowers have excellent sealing designs in key areas such as between the impeller and the casing, and between the shaft and the casing. Mechanical seals, packing seals, and other methods are usually used to effectively prevent gas leakage and ensure the efficiency and safety of the fan.

Function
Gas transportation: The main function of Roots blower is to transport gas. By rotating the impeller, negative pressure is formed at the inlet to suck in gas, and then the gas is discharged at the outlet, thereby achieving the transportation of gas from one place to another. It can overcome pipeline resistance and other factors under certain pressure to transport gas to a longer distance or higher height.
Generate pressure or vacuum: Roots blower can generate both positive pressure for blowing gas into the system and a certain degree of vacuum. When used as a vacuum pump, it can generate negative pressure at the inlet and extract gas from the enclosed space.
Purpose
Wastewater treatment: Roots blower is one of the key equipment in the aeration tank of the wastewater treatment plant. It transports air to the bottom of the aeration tank, disperses the air into tiny bubbles through the aeration device, increases the contact area between oxygen and sewage, provides oxygen for microorganisms in sewage, promotes the decomposition of organic matter and the purification of sewage.
Pneumatic conveying: widely used in pneumatic conveying systems in industries such as chemical, food, and building materials.
Aquaculture: Used to oxygenate water in aquaculture ponds or aquariums. By transporting air and increasing the dissolved oxygen in water, sufficient oxygen is provided for aquatic organisms such as fish to maintain their living and growth environment.
Casting industry: used for conveying and compacting molding sand during the casting process. By pneumatic conveying, the molding sand is transported to the molding machine and a certain pressure is provided to compact the molding sand, ensuring the quality of the casting model.
Vacuum application: In some simple vacuum systems, such as small vacuum drying equipment, vacuum adsorption devices, etc., Roots blowers are used as vacuum pumps to create a vacuum environment for drying materials or adsorbing objects.
Advantage
Efficient and energy-saving: Under appropriate working conditions, Roots blowers have high efficiency. Its working principle determines that it can effectively utilize energy within a certain range of flow and pressure. Compared with some traditional ventilation equipment, Roots blowers can consume less energy under the same air volume and pressure requirements.
High reliability: Due to its simple structure, relatively few components, and high manufacturing accuracy of key components such as impellers and gears, the operation reliability of Roots blowers is high. Under normal maintenance, it can operate stably for a long time, reducing the impact of equipment failures on production.
Wide flow range: Roots blower has a wide flow range, and different models of fans can be selected according to actual needs to meet various application scenarios from small flow to large flow. At the same time, its flow regulation is also relatively convenient, which can be achieved by changing the speed, adjusting the inlet and outlet valves, etc.
High cost-effectiveness: Taking into account factors such as performance, price, and service life, Roots blower has a high cost-effectiveness. Its initial investment cost is relatively reasonable, and in the long-term use process, due to its stable performance and low maintenance cost, it can bring good economic benefits to users.
