Analysis of the pressure holding phenomenon of Roots blower and its impact on equipment
Once the pressure holding phenomenon of Roots blower occurs, it will bring many negative impacts on the effectiveness and service life of the blower, as follows:
1. Noise: Due to the negative pressure area inside the Roots blower, sudden pressure fluctuations and air flow will occur when the negative pressure area disappears, resulting in severe noise. This will affect the comfort of the work environment and may also cause interference to surrounding equipment and personnel.
2. Efficiency reduction: When the Roots blower experiences pressure build-up, it will cause a decrease in air pressure inside the blower and increase its load, resulting in a decrease in blower efficiency. This will waste energy and may also affect the normal operation of the production line.
3. Temperature rise: Holding pressure can cause a large amount of heat to be generated during the operation of the Roots blower, leading to an increase in temperature and even causing equipment overheating and malfunction. Long term overheating operation will accelerate the aging and damage of fan components, shortening the service life of the equipment.
4. Motor damage: When the pressure is severely suppressed, it may have a fatal impact on the motor, causing it to burn out. The motor is the core component of the Roots blower, and once damaged, it will seriously affect the normal operation of the blower.
5. Wear of impeller gear: Pressure build-up may also cause severe wear of the impeller gear, especially when the fan reverses direction. Worn impeller gears can affect the performance and stability of the fan, and may even cause damage to the entire machine.
6. Decreased air volume: When the pressure is severely suppressed, the air volume will decrease, resulting in insufficient air volume. This will affect the gas transmission capacity of the fan and cannot meet the needs of the production line.
To avoid pressure build-up during the use of Roots blowers, the following measures can be taken:
1. Regularly inspect and maintain the Roots blower to ensure its mechanical seal and air tightness are good.
2. Add pressure relief ports or install pressure relief valves on Roots blowers to reduce the occurrence of negative pressure areas.
3. Set up warning devices to monitor the operating pressure of the fan, and take timely measures to deal with it when the pressure exceeds the set value.
4. Clean up blockages in pipelines and aeration plates to ensure smooth airflow.
In summary, the phenomenon of pressure build-up in Roots blowers has a significant negative impact on both the equipment and its performance. Therefore, corresponding measures need to be taken during use to avoid the occurrence of pressure build-up.
