Detailed explanation of Roots type aeration blower
Roots type aeration blower is an important industrial equipment, and the following is a summary of its detailed information:
1、 Basic principles
Roots type aeration blower belongs to volumetric rotary blower, which mainly uses two blade shaped rotors to compress and transport gas through relative motion in the cylinder. Its working principle is similar to that of a gear pump, where each rotor is equivalent to a gear with only two teeth. The synchronous gear at the rotor shaft end keeps the two rotors in mesh, and each concave curved surface on the rotor forms a working volume with the inner wall of the cylinder. During the rotation of the rotor, gas is taken away from the suction port. When it is moved to the vicinity of the exhaust port and connected to the exhaust port, the pressure in the working volume will suddenly increase due to the reflux of high-pressure gas, and then the gas will be transported to the exhaust channel.
2、 Main features
1. Forced gas delivery: Roots type aeration blower has the characteristic of forced gas delivery, which can adjust the flow rate within the allowable pressure range, and the flow rate changes very little.
2. Simple structure: Its design makes the overall structure simple, easy to manufacture, and maintenance relatively easy.
3. Long service life: Due to the use of high-quality materials and precision machining processes, Roots type aeration blowers can maintain good working conditions, reduce the probability of failures, and extend their service life.
4. Oil free pollution: The two rotors do not come into contact with each other and are sealed through a tightly controlled gap, ensuring that the discharged gas is not contaminated by lubricating oil.
5. High noise: The noise generated by the Roots type aeration blower during operation can be effectively reduced by optimizing the design and installing mufflers.
3、 Performance parameters
The performance parameters of Roots type aeration blower include flow rate, pressure, speed, power, etc. Among them, the flow rate is 0.151200 cubic meters per minute, the pressure is 9.8196 kilopascals, the speed is 1503000 revolutions per minute, and the power is 0.751000 kilowatts. These parameters can be adjusted according to specific usage requirements.
4、 Main purpose
Roots type aeration blowers are widely used in the field of sewage treatment, mainly to increase the oxygen content in the aeration tank, promote the growth and metabolism of aerobic bacteria, and thus achieve deep treatment and purification of sewage. In addition, it can also be used in other situations that require gas transportation and pressurization, such as pneumatic conveying, mine ventilation, etc.
5、 Usage and maintenance
1. Usage requirements: When using a Roots type aeration blower, it should be ensured that the temperature of the incoming medium conveyed does not exceed 40 ℃, the content of particulate impurities in the medium does not exceed 1000mg/m3, and the size of the particles should be below 0.1mm.
2. Preparation before starting: Before starting the Roots aeration blower, various preparations should be made, including checking whether the air filter at the inlet is unobstructed and whether the pipeline valves are stable.
3. No load operation: After starting up, perform a no-load operation for 20-30 minutes and observe for any abnormal phenomena.
4. Load startup: After the no-load operation is normal, the load startup can be carried out and the outlet valve can be gradually adjusted to the rated pressure.
5. Shutdown operation: During normal shutdown, the bypass pipe should be opened first for "venting", and the power should be cut off and the intake valve should be closed after the pressure drops.
6. Daily maintenance: The temperature and condition of components such as bearings and lubricating oil in the oil tank should be checked regularly, and lubricating oil should be replaced and filter screens should be cleaned in a timely manner.
In summary, the Roots type aeration blower has been widely used in various fields such as sewage treatment due to its unique performance characteristics. During use, operation and maintenance should be strictly carried out in accordance with the usage requirements and maintenance standards to ensure the normal operation of the equipment and extend its service life.
