Rotary fan, also known as rotary fan or rotary blower, is a pneumatic equipment widely used in various industrial fields. The following is a detailed introduction to the rotary fan:
1、 Working principle
The working principle of a rotary fan is to compress and discharge air through the eccentric rotation of the rotor inside the cylinder. During the rotation of the rotor, gas is drawn into the interior of the fan, compressed by the movement of the rotor, and then discharged from the outlet. This design ensures that the gas does not generate significant vortices during rotation, thereby guaranteeing the stability and uniformity of the airflow.
2、 Main components
The main components of a rotary fan include a motor, an air transition device, a blower body, an air chamber, a base (also serving as an oil tank), a drip nozzle, etc. Among them, the blower relies on the eccentric operation of the rotor biased inside the cylinder, causing the volume between the blades in the rotor slot to change, thereby sucking in, compressing, and discharging air.
3、 Characteristics and advantages
1. Small size and large air volume: The rotary fan adopts the principle of operating compressed air. Although it is small in size, it has a large air volume and can meet the gas transportation needs of various industrial fields.
2. Low noise and energy-saving: Compared with other types of fans, rotary fans have lower noise and energy consumption, making them suitable for use in situations that require silent operation and energy conservation.
3. Smooth operation and easy installation: Small models have minimal vibration during operation and do not require the installation of anti vibration devices, making installation very convenient.
4. Resistance to load changes and stable air volume: Even in the face of load changes caused by pressure changes, the air volume changes very little with pressure changes, ensuring the stability of gas transportation.
5. Equipped with an air chamber for smooth air dispersion: The model comes with an air chamber to prevent air pulsation and ensure smooth air dispersion.
6. Excellent material quality, clever structure, and outstanding performance: The blower is made of high-quality materials, with exquisite structure, sturdy and durable, excellent performance, and few faults that occur during long-term use.
7. Simple maintenance, few malfunctions, and long service life: Due to low speed and minimal wear, the maintenance of the rotary fan is simple, with few malfunctions and a long service life.
4、 Application Fields
Rotary fans have a wide range of applications in various fields, including but not limited to:
1. Industrial production: used for ventilation, exhaust, gas transportation and other occasions.
2. Water treatment: In sewage treatment plants, rotary fans are commonly used for aeration in aeration tanks to maintain the life activities of microorganisms.
3. Agriculture: Greenhouse ventilation helps regulate temperature and humidity.
4. Architecture: The air circulation of the air conditioning system improves indoor air quality.
5、 Maintenance and upkeep
In order to ensure the stable and reliable operation of the rotary fan, regular maintenance work is required, including but not limited to:
1. Clean the air filter: Regularly clean the air filter to prevent blockages from affecting intake efficiency.
2. Adjust the V-belt: After the fan runs for a period of time, the V-belt will stretch, and its tightness needs to be adjusted to ensure transmission efficiency.
3. Check the flexibility of the valve: ensure reliable opening and closing of the valve.
4. Daily inspection: including checking whether the equipment has oil leaks, the leaking parts, and the operation status of the fan and motor.
5. Lubrication: Regularly adding oil to the bearings can reduce wear and extend the service life of the machine.
In summary, the rotary fan plays an indispensable role in both industrial production and civilian applications due to its unique working principle, excellent performance characteristics, and wide range of application fields.
