& The centrifugal compressor rotor causes excessive bearing vibration due to imbalance, causing bearing bush wear. The rotor should be dynamically balanced to reduce the unbalance. If the bearing installation does not meet the requirements, for example, the bearing seat of the thrust bearing is skewed, the load on the thrust bearing pads will be uneven, and the temperature of the bearing pads will increase, which will greatly reduce the bearing capacity of the bearing and may cause the thrust bearing to fail. damage. The Babbitt alloy casting quality of the bearing bush is unqualified. The Babbitt alloy may have defects such as falling off, cracks, and blisters, and contain impurities such as iron filings and sand grains. The bearing structure is unreasonable, the bearing bush is overloaded, and the bearing bush and the bearing cannot form liquid friction. The compressor balance plate seal, interstage seal teeth are damaged, or the partition plate leaks, which increases the axial force on the rotor and increases the load on the thrust bearing. Treatment method: The normal operation of the bearing not only depends on the quality of the bearing structure itself, manufacturing, installation and maintenance, but also depends on changes in the operating conditions of the compressor and the working conditions of the oil supply system. Therefore, during maintenance, the regulations of maintenance process standards must be strictly followed to ensure quality. During operation, special attention should be paid to monitoring the bearing temperature, lubricating oil temperature, axial displacement, whether the oil supply system is working properly, whether the vibration of the bearing is excessive, and whether there are any abnormal sounds, etc. If there is an abnormality, analysis and judgment should be made immediately, and effective measures should be taken to deal with it to avoid accidents. Many customers who use centrifugal air compressors have this question, why should the air of centrifugal air compressor accessories be purified? Centrifugal air compressor accessories and hydraulic systems have high requirements for the cleanliness of hydraulic oil, and pneumatic systems also have high requirements for compressed air. The air discharged by the air compressor cannot be used directly by pneumatic devices. The air compressor inhales air containing moisture and dust from the atmosphere. After compression, the temperature of the air increases to above ℃. At this time, the lubricating oil in the air compressor also partially becomes gaseous. In this way, the compressed air discharged from the air compressor is high-temperature gas containing oil, moisture and dust. If this compressed air is directly sent to the pneumatic system, the reliability and service life of the pneumatic system will be greatly reduced due to poor air quality. The resulting losses often greatly exceed the cost of the air source treatment device and the service of the centrifugal air compressor. cost, so the correct selection of air source treatment system is absolutely necessary. Centrifugal air compressors will work best if they receive adequate maintenance during operation. Correct maintenance can increase the service life of centrifugal air compressors of major brands and greatly save downtime due to malfunctions. Henan Haijie Technology Co., Ltd. is a professional centrifugal air compressor maintenance manufacturer. It has been committed to maintaining various brands of centrifuges for many years. There are many reasons for centrifugal air compressor failures, including unbalanced rotor loading or asymmetric test tube insertion. is the most common reason. Today, Henan Haijie will mainly analyze the reasons for the unbalanced loading of the centrifugal air compressor rotor. During the rotation of the rotor, its base usually rolls around a certain center of the circle, and synchronous center rolling occurs, which is called precession. The factors that occur are: poor planning, relatively close working speeds, deviation of the rotor center (including the centrifuged sample), etc. First of all, when the centrifuge is being repaired and maintained, the weight and installation location of the replaced parts are different from the original parts, or collision with the rotating rotor will also cause the rotor to rotate unstable. Secondly, although the centrifugal air compressor test tubes are placed symmetrically, the density of the solution contained in the corresponding tubes is different, resulting in a different mass distribution of the substances contained in the two opposite tubes. The last thing to note is that the method of installing the rotor is incorrect, especially when the rotor is stuck to the main shaft. You must not hit it with a hard object or pull the rotor at a certain angle with the rotating shaft.
