　　What are the common faults of centrifugal air compressor? As the core power equipment of modern industrial production, the running stability of centrifugal air compressor directly affects the efficiency of the whole production system. In long-term use, centrifugal air compressors often fail due to improper operation, aging parts or environmental factors. The following Turbo-Tech will analyze the faults and causes of centrifugal air compressor for you, and provide targeted maintenance solutions.

　　What are the common faults of centrifugal air compressor? Mainly as follows:

　　(1) mechanical failure

Bearing failure: the bearing of centrifugal air compressor is the key component to support the rotor. Wear, damage or poor lubrication of bearings will aggravate rotor vibration, which will lead to a series of problems, such as seal damage and blade wear. The common manifestations of bearing faults include abnormal noise, rising temperature and increasing vibration amplitude.

Impeller failure: Impeller is the core component of centrifugal air compressor, and its damage is usually caused by foreign matter entry, long-term wear or manufacturing defects. The deformation, fracture or corrosion of impeller blades will reduce the efficiency and performance of air compressor, and even cause the equipment to fail to operate normally in serious cases.

Failure of the coupling: the coupling is used to connect the motor and the rotor of the air compressor. If the coupling is badly centered, worn or damaged, it will lead to misalignment of the rotor, which will cause vibration and additional mechanical stress, and affect the stability and service life of the equipment.

　　(2) Pneumatic failure

Air intake system failure: air intake filter blockage, air intake valve failure or air intake pipe leakage will affect the air intake volume and air intake quality of air compressor. This may lead to insufficient air displacement of air compressor, rising exhaust temperature and increasing energy consumption.

Failure of cooling system: centrifugal air compressor will generate a lot of heat during operation, and the function of cooling system is to take away this heat to keep the equipment running in the normal temperature range. Cooling system problems such as blocked cooler, coolant leakage or cooling fan failure will lead to overheating of equipment, reduce efficiency and even damage equipment.

　　(3) Electrical failure

Motor failure: the motor is the power source to drive the air compressor to run, and its failure may include winding short circuit, open circuit, insulation aging and other problems. Motor failure will lead to the failure of air compressor to start or unstable operation, and may also lead to overheating, abnormal current and other phenomena.

Control system failure: Modern centrifugal air compressors are usually equipped with complex control systems to monitor and adjust the operating parameters of the equipment. Control system faults may include sensor failure, short circuit or open circuit of control circuit, controller program error, etc., which will lead to equipment failure to start normally, abnormal operating parameters or automatic protection function failure.

Diagnosis and repair of common faults of centrifugal air compressor

Fault diagnosis method: when the equipment fails, scientific diagnosis method should be adopted to determine the cause of the failure quickly and accurately. Combined with the operation parameters, fault phenomena and maintenance experience of the equipment, fault tree analysis, vibration analysis, infrared thermal imaging and other technical means can be used to comprehensively diagnose the fault.

Quick repair strategy: after determining the cause of the failure, repair measures should be taken as soon as possible to reduce the downtime of the equipment. For some common faults, such as bearing wear and motor failure, corresponding spare parts should be prepared for timely replacement. For complex faults, a professional maintenance team should be organized to carry out emergency repair, and the repair process should be carried out in strict accordance with maintenance technology and quality standards to ensure the normal operation of the repaired equipment.

Testing and verification after repair: After the repair is completed, the equipment shall be comprehensively tested and verified to ensure that the fault has been completely eliminated and all performance indexes of the equipment return to normal. The test contents include no-load operation test, load operation test and performance parameter test to verify the stability and reliability of the equipment.

　　What are the common faults of centrifugal air compressor? The common faults of centrifugal air compressor are various, and the maintenance strategy should be adjusted flexibly according to the specific situation. By implementing preventive maintenance, scientific fault diagnosis and repair, and timely updating and upgrading of equipment, the operating efficiency and reliability of equipment are improved, and stable gas supply is provided for enterprise production.
