The maintenance of Roots blower covers multiple aspects, and the following is a detailed summary of its maintenance content:
1、 Routine maintenance
1. Keep clean: The blower room should be kept clean to ensure that the equipment surface is free of soil and oil stains.
2. Check bolts: Regularly (monthly) check the tightness of each connecting bolt of the fan to ensure a secure connection.
2、 Lubricating oil management
1. Replace with new oil: After 48 hours of operation of a new or overhauled fan, the lubricating oil in the oil tank should be replaced and the specified brand of lubricating oil should be refilled.
2. Gearbox oil change: The lubricating oil grade of the gearbox should meet the requirements of the product specifications. After continuous operation for 500 hours, new oil should be replaced.
3. Oil injection for rolling bearings: Lubricating oil must be added once a week to ensure good lubrication of the bearings.
4. Oil injection for shaft sealing device: The shaft sealing device should be filled with engine oil every 24 hours to ensure sealing performance.
5. Oil quality management: Lubricating oil or grease should be inspected, stored, and guided for use by a dedicated person. The oil quality should be checked regularly to prevent impurities or water emulsification.
3、 Equipment maintenance
1. Shaft seal oil drain: The shaft seal oil drain plug should be opened once a week to remove waste oil. If there is a trace of moisture in the shaft seal, in order to reduce the impact of hot air on the bearing, this bolt can be kept normally open, but the oil seal oil should be injected accordingly.
2. Avoid long-term backup: The fan should avoid long-term backup as much as possible and adopt dynamic backup mode to alternate the operation of the blower to prevent the motor from being affected by moisture and insulation reduction.
3. Rotating shaft: After shutdown, the blower should rotate the shaft every 24 hours and flip it 180 ° to change the position of the fan blades, which may cause rusting of the bearings.
4. Operation cycle arrangement: In order to extend the service life of the fan and arrange the maintenance period reasonably, the operation cycle of the blower should be appropriately arranged to achieve cross use. Continuous operation units should be replaced regularly.
4、 Operation monitoring
1. Monitoring parameters: Regularly check the pressure and temperature of the blower inlet and outlet, the liquid, pressure, and temperature of cooling water or oil, and the pressure difference of the air filter. Make daily reading records and analyze and compare them.
2. Cleaning the filter: Regularly clean and inspect the air filter to maintain its normal operation.
3. Adjust the throttling device: Pay attention to the impact of intake temperature on the operating conditions of the blower, and adjust the throttling device of the inlet guide vane or butterfly valve in a timely manner to ensure stable operation of the blower.
5、 Sound and vibration monitoring
1. Listening to sound: Regularly pay attention to and listen to the sound of the unit's operation. If any abnormalities are found, take measures in a timely manner. If necessary, stop the machine for inspection, identify the cause, and troubleshoot.
2. Monitoring vibration: Regularly monitor the vibration of bearings to ensure that the vibration is within the normal range.
6、 Electrical system inspection
1. Check electrical components: Regularly check whether the wiring of the electrical system is secure, whether the motor is overheated, and whether the electrical components are damaged.
2. Insulation testing and grounding inspection: Regularly conduct insulation testing and grounding inspections on the electrical system to ensure its reliability.
7、 Other precautions
1. Check valve: Regularly check the flexibility of the valve to ensure that it can be reliably opened and closed.
2. Check dropper: Regularly check if the dropper drips water normally. If the dropper is dirty, please remove the adjusting screw for cleaning.
3. Check sealing: Regularly inspect all parts of the fan for oil and gas leaks, and repair them. If it cannot be repaired, please notify the manufacturer immediately.
4. Establish maintenance records: Establish a maintenance record system for Roots blowers, detailing the content and dates of each maintenance and upkeep. Track the maintenance status of the fan through maintenance records, and promptly identify and resolve potential issues.
In summary, the maintenance of Roots blowers includes routine maintenance, lubricant management, equipment maintenance, operation monitoring, sound and vibration monitoring, electrical system inspection, and other precautions. Through maintenance and upkeep, it can be ensured that the Roots blower is always in good operating condition, improving its efficiency and lifespan.
