　　Centrifugal air compressor how to carry out maintenance? Due to the precise structure and extremely high speed of centrifugal air compressors, if there is no maintenance for a long time, or the maintenance is not in place, it will affect the gas production efficiency and may cause serious equipment failures. Therefore, establishing a scientific and perfect maintenance system is the key to ensure the high energy efficiency operation of centrifugal air compressors.

　　Centrifugal air compressor how to carry out maintenance? 

　　Ⅰ. Key points of daily maintenance

　　1. Lubrication system maintenance

　　Lubricating oil is centrifugal air compressor "blood". The oil level, oil quality and oil temperature should be checked regularly to ensure that the lubricating oil is clean and free of impurities. It is generally recommended to change the lubricating oil every 2000-4000 hours of operation, and change the oil filter simultaneously. If the oil is found to be emulsified, discolored or contains metal debris, stop the machine immediately for inspection.

　　2. Air filtration system cleaning

　　Intake air filter directly affects the cleanliness of compressed air and the operating efficiency of equipment. The filter element should be cleaned or replaced regularly according to the working condition. In multi-dust, it is recommended to shorten the inspection cycle to once a week to prevent the blockage of the filter element from increasing the air intake resistance and energy consumption.

　　3. Cooling system inspection

　　Centrifugal air compressor produces a large amount of heat during operation, and the effectiveness of the cooling system is directly related to the service life of the equipment. It is necessary to regularly check whether the cooler is scaled, whether the cooling water flow is normal, and whether the cooling fan is running smoothly. For water-cooled units, chemical cleaning is recommended once a year to remove scale deposits.

　　4. Vibration and temperature monitoring

　　Vibration analyzer and infrared thermometer are used to regularly check the vibration value and temperature of key parts such as bearings and gearboxes. Abnormal vibration is often an early signal of bearing wear, rotor imbalance or poor alignment of couplings, and timely detection can avoid the expansion of accidents.

　　II. Common Faults and Maintenance Strategies

　　1. Displacement drop

　　Possible causes include: wear or fouling of impellers, clogged intake filters, leaking seals, slipping of drive systems, etc. During maintenance, check one by one, clean or dynamically balance the impeller if necessary, and replace the aging seals.

　　2. Bearing temperature is too high

　　Usually caused by poor lubrication, improper bearing clearance, or insufficient cooling. Check the oil supply pressure, oil passage patency, measure the bearing clearance, replace the bearing if necessary and re-.

　　3. Abnormal vibration and noise

　　Excessive vibration may result from unbalanced rotors, damaged bearings, loose foundations, or excessive pipe stress. Vibration spectrum analysis should be carried out, fault sources should be accurately located, and targeted measures should be taken, such as re-balancing, tightening foundation bolts, pipeline support and so on.

　　4. Surge phenomenon

　　Surge is a peculiar dangerous working condition of centrifugal air compressor, which is manifested as periodic backflow of air flow and vibration of unit. Common inducements include: working point falling into the surge zone, inlet air pressure is too low, outlet pipe network resistance abrupt change and so on. Check whether the anti-surge valve is sensitive and reliable, and verify whether the actual operating conditions are within the reliable range.

　　Ⅲ. Special maintenance suggestions for centrifugal air compressors

　　1. Formulate a preventive maintenance plan: According to the operating hours of the equipment, establish a daily inspection, weekly inspection, monthly inspection, and annual inspection system, so as to achieve "equal emphasis on maintenance and repair, and focus on prevention".

　　2. Establish equipment files: record in detail the content of each maintenance, replacement of parts, and changes in operating parameters to provide data support for fault diagnosis.

　　3. Choose original accessories: For key components such as bearings, seals, impellers, etc., it is recommended to use original accessories to ensure matching accuracy and service life.
