What is the configuration of an explosion-proof Roots blower?
Release date:
2021-12-01
The explosion-proof Roots blower is a positive-displacement fan with membrane seals at the ends of the impellers and at the front and rear of the fan. Its operating principle is based on two blade-shaped rotors that move relative to each other inside a cylinder, thereby compressing and conveying gas—a rotary compressor. This blower features a simple structure and is easy to manufacture. It is widely used in applications such as oxygen enrichment in aquaculture, aeration in wastewater treatment, and cement transportation. It can also serve as a more suitable solution for gas delivery and pressurization systems, vacuum pumps, and other applications requiring low-pressure conditions.
Explosion-proof Roots blower It is a positive-displacement fan with membrane sounds at the front and rear ends of the impeller. Its operating principle is based on a rotary compressor that uses a dual-blade rotor moving relative to each other within a cylinder to compress and convey gas. This blower features a simple structural design and convenient manufacturing technology, making it widely applicable in areas such as oxygen enrichment for aquaculture in China, aeration for wastewater treatment, cement transportation, and even as a gas delivery and pressurization control system—particularly suitable for scenarios involving small pressure fluctuations—as well as vacuum pumps.
What is the configuration of an explosion-proof Roots blower?
This rotary fan consists of a housing, wall plates, an impeller, an oil tank, and a silencer.
Explosion-proof Roots blower Housing: Primarily serves to provide structural support (wall panels, impellers, silencers) and functions as a fixed asset.
Explosion-proof Roots blower Wall plates: Primarily used to connect the housing to the impeller, support the impeller's rotation, and create an end-face sealing effect.
Impeller: The rotating component of a Roots blower, available in two-leaf and three-leaf designs. However, the three-leaf impeller has numerous advantages over the two-leaf design—such as higher pressure generation, lower noise levels, and smoother operation—and has gradually replaced the two-leaf Roots blower.
Explosion-proof Roots blower Fuel tank: Primarily used for storing lubricating oil for system lubrication of gears and bearings.
Silencer: Used to reduce noise generated by airflow pulsations when air enters and exits the Roots blower.
What is the principle analysis of an explosion-proof Roots blower?
The rotary lobe blower is a positive-displacement fan in which two three-lobe rotors rotate in opposite directions within a sealed space formed by the casing and side walls. Since each rotor is equipped with a honeycomb or outer ring around it, and all three rotors are identical, as are the two rotors themselves, the manufacturing difficulty is significantly reduced. During rotor machining, CNC equipment can be employed. As long as the distance between the centers of the two rotors remains constant and a minimum clearance is maintained regardless of the rotational positions of the two rotors, gas leakage can be kept within acceptable limits.
The clearances between the impellers themselves, between the impellers and the casing, and between the impellers and the wall plates are extremely small. As a result, a vacuum is created at the intake port, and air flows into the intake manifold under the influence of atmospheric pressure. Subsequently, the two blades of each impeller, together with the wall plates and the housing, form sealed cavities. As the impellers rotate, the air entering the intake passage continuously forms enclosed spaces that are sealed by the two blades. Consequently, the air trapped between the two differently structured blades is compressed, enabling it to keep moving. Thus, air is continuously conveyed from the intake port to the exhaust port. Explosion-proof Roots blower The entire process of work development.
What are the characteristics of explosion-proof Roots blowers?
Due to Explosion-proof Roots blower Adopting a three-lobe rotor system design and making reasonable use of the inlet and outlet structures within the housing, the fan exhibits low vibration and low noise.
The impeller and shaft are integrated into a single structure, ensuring that the impeller is wear-free, maintaining consistent fan performance, and enabling long-term continuous operation.
Explosion-proof Roots blower High working volume utilization, high volumetric efficiency, compact structure, and flexible and versatile installation and management methods.
A complete range of models to meet the diverse needs of other users.
