Rotary blower is a uniquely designed low-noise blower. The following is a detailed introduction about it:
1、 Working principle
The working principle of a rotary blower is to use the centrifugal force of a rotating cylinder to push gas between the inlet and outlet. Specifically, when the cylinder rotates, air is drawn in from the inlet of the cylinder due to centrifugal force and carried downstream towards the edge of the cylinder under the action of centrifugal force. At the edge of the cylinder, air is pushed out of the centrifuge outlet. In addition, it is also believed that the rotary blower relies on the eccentric operation of the rotor biased inside the cylinder, causing the volume changes between the blades in the rotor slot to suck in, compress, and discharge air.
2、 Main components
The main components of a rotary blower include the motor, drive device, blower housing, impeller, and inlet and outlet pipelines. Among them, the motor drives the rotation of the impeller through the driving device, thereby forming an airflow. The blower housing serves to fix and protect the impeller, while also being connected to the external air through inlet and outlet pipes.
3、 Performance characteristics
1. Low noise: The rotary blower adopts a unique low-noise design, ensuring smooth operation.
2. Energy saving: Its compact structure can meet various aeration requirements for water treatment, and the energy-saving effect is significant.
3. Strong adaptability: suitable for various occasions, such as water treatment aeration, sewage treatment, printing industry, etc.
4. Stable operation: When the load changes, the air volume remains stable and the performance is excellent.
5. Easy maintenance: The rotary blower has a relatively simple structure, making it easy to maintain and clean.
4、 Application Fields
Rotary blowers are widely used in industrial fields such as mining, chemical, metallurgical, and construction, for eliminating harmful gases, ventilation, and water supply and drainage processes. At the same time, it is also applied in agricultural fields such as greenhouses and breeding farms, providing a suitable ventilation environment for crops. In addition, rotary blowers can also be used in water treatment systems for process steps such as air flotation and aeration. The application of rotary blowers is also quite common in sewage treatment plants, industrial parks, and other places.
5、 Maintenance and upkeep
In order to ensure the long-term stable operation of the rotary blower, regular maintenance and upkeep are required. This includes:
1. Regularly check the oil level in the fuel tank: ensure that the oil level is not below the mark, and if the oil is insufficient, it should be replenished in a timely manner.
2. Check the oil condition: Check the oil condition daily. If water or dirt is found to cause deterioration, replace the oil immediately with a new one.
3. Keep the fan room clean: Regularly clean up debris and dust to ensure a clean operating environment for the fan.
4. Check the operation status: closely monitor the operation status of the fan and motor. If abnormal noise or high temperature is found, the machine should be stopped immediately for maintenance.
6、 Model and Parameters
There are various models and parameters of rotary blowers to meet the needs of different industrial fields. Common parameters include air volume, pressure, caliber, motor power, etc. For example, the air volume range of the 80 type rotary blower may be between 2.36-5.71m3/min, with a wide range of applicable pressures from 9.8kPa to higher pressure levels (such as 98kPa), and the motor power may be 4kw, etc. When selecting, users should comprehensively consider their actual needs and working conditions.
