Technical Specifications for Maintenance of Centrifugal Fan Turbine
Centrifugal fan turbine is a kind of maintenance equipment commonly used by industrial and mining enterprises. It has the advantages of energy saving, convenient installation, low noise and pollution, high thrust and large air volume. In the process of its operation, the turbine is gradually worn, the operation becomes unstable and the thrust decreases. Therefore, it is necessary to make troubleshooting on time. In this paper, the author will discuss the technical standards for the maintenance of centrifugal fan turbine, so as to improve the service life of the machine and reduce the failure rate of the system.
Firstly, when troubleshooting, the personnel should confirm the parts that need to be maintained in the centrifugal fan turbine, including the main parts such as the rotor, stator, inlet, outlet, casing and bearing, and then decide the method of troubleshooting according to the degree of wear. If there is only a slight wear, a light material can be used to polish the surface of the turbine. However, if the wear is serious, it is necessary to replace the worn parts with new ones.
Secondly, personnel should check whether there is sand and gravel in the turbine for cleaning. If sand and gravel are found, they should be removed as soon as possible to prevent damage to the centrifugal fan turbine. At the same time, personnel should inspect the lubrication of bearing, lubricating components and lubrication channel. If the lubrication is not in good condition, it is necessary to add lubricating oil, change the lubricating oil regularly and keep the lubricating system clean.
Thirdly, personnel should inspect the running balance of the rotor. For the rotor running balance, personnel can use two sound reflection method, the vibration acceleration amplitude measurement method, the accelerator signal analysis method and the method of Fourier transform to detect the running balance of the rotor. Personnel should adjust the balance according to the unbalanced distance or mass of the rotor detected by these methods.
Fourthly, personnel should also calculate the vibration signal of the turbine to see if it changes abnormally over time. Calculating the vibration signal of the turbine can help personnel to detect the vibration situation of the turbine in the entire operation process, and adjust the running state if there is an abnormality.
Finally, after the maintenance of the centrifugal fan turbine is completed, personnel should confirm the parts that have been maintained and replaced, clean the turbine and related parts, and perform a comprehensive test to ensure that the turbine can be safely put into operation.
In summary, the technical standards for maintenance of centrifugal fan turbine include determining the parts to be maintained, cleaning and replacement, confirming the running balance of the rotor, calculating the vibration signal of the turbine and performing comprehensive test after the maintenance of the turbine. Following these standards can help extend the service life and improve the operation performance of the centrifugal fan turbine.
