The three blade spiral Roots blower, commonly referred to as the three blade Roots blower, is an important industrial equipment. The following is a detailed introduction to the three bladed spiral Roots blower:
1、 Definition and Structure
The three bladed spiral Roots blower is a double bladed synchronous compression machine, with each three bladed rotor supported by two bearings and a pair of synchronous gears to maintain the relative position of the two rotors constant. Its structure is compact, mainly composed of a casing, wall panels, impellers, inlet and outlet mufflers, bearing seats, gearbox and other parts.
2、 Working principle
The working principle of the three bladed spiral Roots blower is based on the principle of Roots blower, which generates wind pressure by pushing the airflow through the rotation of the rotor blades. Specifically, when the impeller begins to rotate, it will suck in the surrounding air or gas. During the rotation of the impeller, due to the centrifugal force, the air is accelerated and moves towards the outlet direction of the impeller. As the impeller continues to rotate, air or gas will be continuously pushed towards the outlet of the impeller, thereby achieving gas transportation and compression.
3、 Performance characteristics
1. Energy saving: Three leaf Roots blower has the advantages of high volumetric efficiency and good power balance, which can achieve energy-saving operation.
2. Smooth operation: Due to the small gaps between rotors, rotors and pump bodies, and rotors and side covers, there is no friction in the working chamber, resulting in smooth operation and low noise.
3. Economical and durable: Three leaf Roots blower does not require lubrication, has a long service life, simple structure, and easy maintenance.
4. Widely applicable: It can be used to transport various gases such as air, coal gas, hydrogen, acetylene, carbon dioxide, etc. It is widely used in many fields such as petrochemicals, building materials, electricity, smelting, fertilizers, mines, ports, textiles, food, papermaking, aquaculture and sewage treatment, environmental protection industry, etc.
4、 Selection and Application
When selecting, it is necessary to choose the appropriate three blade Roots blower model and specifications based on the gas type, flow rate, pressure, and other requirements of the actual usage scenario. At the same time, factors such as the installation method and maintenance convenience of the fan also need to be considered.
Three leaf Roots blowers have a wide range of applications in multiple fields. For example, in sewage treatment, it is commonly used for aeration and oxygenation; In food processing, it can be used for conveying and processing grains, flour, vegetables, etc; In mining and metallurgy, gas transportation and ventilation systems can be used for mining minerals and extracting metals; In the field of environmental protection, it can be used in environmental protection equipment such as flue gas desulfurization, denitrification, and dust removal to assist in reducing industrial waste gas emissions.
5、 Maintenance and upkeep
To ensure the long-term stable operation of the Three Leaf Roots blower, regular maintenance and upkeep are required. Specific tasks include:
1. Regularly check the exhaust temperature, bearing temperature, motor current and other parameters of the fan to ensure that they are within the normal range.
2. Regularly clean the dust and debris inside the fan to keep the equipment clean.
3. Pay attention to checking the lubrication condition of the grease and replace or supplement the lubricating oil in a timely manner.
4. If abnormal operation or malfunction of the fan is found, it should be stopped in a timely manner for inspection and handling.
In summary, the three bladed spiral Roots blower has been widely used in various industrial fields due to its energy-saving, stable operation, and economic durability advantages. In the selection and application process, it is necessary to fully consider factors such as actual usage needs and maintenance convenience. At the same time, regular maintenance and upkeep are also key to ensuring the long-term stable operation of the fan.
