AlfaLaval centrifuge It is a kind of equipment for solid-liquid separation, widely used in chemical, pharmaceutical, environmental protection and other industries. This article will introduce the use tutorial and FAQ of AlfaLaval centrifuge to help users operate and maintain the centrifuge better.

1、 AlfaLaval centrifuge tutorial

Preparation Before using AlfaLaval centrifuge, some preparations are required. First, confirm that the power supply of the centrifuge is connected to ensure that the power supply is normal. Secondly, check whether the components inside the centrifuge are intact, such as centrifuge basket, rotating shaft, bearing, etc. Finally, check whether the lubricating oil of the centrifuge is enough, and add an appropriate amount of lubricating oil before operation.

Set process parameters Set the process parameters of the centrifuge according to the specific requirements of the separation experiment. This includes speed, temperature, sample loading, etc. Alfa Laval The rotational speed is generally adjusted according to the size and density of particles, and larger particles generally require higher rotational speed; The temperature should be adjusted according to the melting point and stability of the sample to avoid decomposition or reaction of the sample at high temperature; The sample loading amount needs to be adjusted according to the sample concentration to avoid the centrifuge imbalance caused by excessive loading.

Start separation and add the sample to the centrifuge basket, and ensure that the centrifuge basket is balanced. Put the basket into the centrifuge, close the cover and fasten the bolts. Start the centrifuge according to the set process parameters. After the centrifuge starts to run, the speed and time can be adjusted as required to achieve the best separation effect. In the process of centrifugation, if it is necessary to stop the centrifuge, the rotating speed can be gradually reduced. After the centrifuge stops, open the centrifuge cover and take out the basket.

Cleaning and maintenance After using the centrifuge, it is necessary to clean and maintain the centrifuge in time. First, take out the basket and clean it. WANNER Clear water or suitable solution can be used to clean the internal and external parts of the centrifuge. Be careful not to directly flush the electronic components of the centrifuge with water. After cleaning, dry the basket and other parts and store them in a dry and ventilated place. At the same time, regularly check whether the parts of the centrifuge are worn or damaged, and replace them in time.

2、 FAQ

What should I do if the rotating speed of the centrifuge is unstable or cannot reach the set value? It may be that the power supply of the centrifuge is unstable or there is a problem with the components inside the centrifuge. First, check whether the power supply is normal. If the power supply is unstable, replace the power supply or use a voltage regulator; Secondly, check whether the parts inside the centrifuge are loose or damaged, such as rotating shaft, bearing, etc. If there is any problem, it needs to be repaired or replaced in time.

What should I do if there is abnormal noise or vibration during the operation of the centrifuge? It may be caused by imbalance of centrifuge basket or wear of internal parts of centrifuge. First, check whether the centrifuge basket is balanced. If it is unbalanced, reload the sample or adjust the basket position; Secondly, check whether the parts of the centrifuge are worn. If there is obvious wear, replace them in time.

What should I do when the centrifuge starts displaying fault codes? The failure code displayed when the centrifuge is started may be the failure of electronic components inside the centrifuge. At this time, the meaning of the corresponding fault code can be queried according to the centrifuge manual or user manual, and the corresponding processing can be carried out. If it cannot be solved by itself, it is recommended to contact the manufacturer's technical support or maintenance personnel for handling.

What to do if the centrifuge separation effect is not ideal? It may be that the process parameters of the centrifuge are set unreasonably or the sample in the centrifuge basket is loaded unevenly. First, you can readjust the process parameters of the centrifuge, such as speed, temperature, etc., and adjust them appropriately according to the characteristics of specific samples; Secondly, check the loading of the samples in the centrifuge basket. If the samples are found to be loaded unevenly, reload the samples or take other appropriate methods.

Through the above tutorials and FAQs, I hope it can help users operate and maintain AlfaLaval centrifuge better. WANNER Authorized Agent When using the centrifuge, pay attention to safe operation, ensure the stability and operation effect of the centrifuge, and improve the accuracy and reliability of the experiment. If problems cannot be solved, it is recommended to seek the help of relevant professionals in a timely manner.
