Daily maintenance of the centrifuge is the key to ensure its stable operation, extend its service life and maintain efficient separation performance. The following are the key points of daily maintenance of the centrifuge:
Cleaning and maintenance
External cleaning:
After each use of the centrifuge, the inner and outer surfaces of the centrifuge should be wiped in time to remove dust, dirt, etc., and keep the centrifuge clean.
Internal cleaning:
Regularly clean the inside of the centrifuge chamber, including checking and removing samples, dust accumulation or glass residues left by broken sampling tubes.
For refrigerated centrifuges, special attention should be paid to cleaning the accumulated water in the centrifuge chamber, because this accumulated water may be formed by frost in the centrifuge chamber caused by moisture in the air. Most large-capacity centrifuges do not have drainage holes, and the accumulated water will increase. The rotor should be removed regularly for cleaning. It is recommended to use a mild detergent and ensure that the inside of the centrifuge is completely dry. Avoid using chemicals such as acetone that may damage the centrifuge.
Component inspection and replacement
Sealing ring inspection:
Regularly check the rubber sealing rings at the contact point between the upper part of the centrifugal chamber and the door cover, and the contact point between the rotor seat and the bottom of the centrifugal chamber to ensure that there is no damage, deformation or aging. If necessary, replace them in time.
Rotor inspection:
Regularly check whether the rotor and cover are clean, scratched, deformed or damaged. Check whether the speed disc is clean and damaged. If necessary, clean it with alcohol and wait for it to dry before use. The damaged speed disc needs to be replaced in time. Check whether the rotor has corrosion spots, grooves, small cracks and other damage. Once found, it should be stopped and repaired or replaced immediately.
Other component inspection:
Check whether the door cover pneumatic support rod and door lock switch can work normally. Check whether the motor bearings need to be filled with lubricating oil, and check and maintain them regularly. Check the wear of the commutator and brushes. If they are excessively worn, they need to be replaced immediately. Maintain the function of your product with regular checks and upkeep, including motor bearing lubrication and inspection of components like the door cover pneumatic support rod and door lock switch, as well as regular monitoring of the commutator and brushes for excessive wear that may require immediate replacement.
Electrical system inspection
1. Check the power cord and plug: Check the power cord, plug, socket and other electrical components regularly for damage, and replace them if necessary.
2. Check the motor operation: During the use of the centrifuge, pay attention to the sound of the motor operation and check for abnormal noise or vibration. If abnormal, stop the machine immediately for inspection.
Ventilation and heat dissipation
Check the cooling fan: Check regularly whether the cooling fan can work normally to ensure that it can effectively dissipate heat and prevent the motor from overheating.
Clean the ventilation window and condenser: Clean the dust on the centrifuge ventilation window and condenser regularly to ensure the ventilation effect and the heat transfer effect of the condenser. It’s important to keep your centrifuge running smoothly. Regularly cleaning the dust off the ventilation window and condenser allows for optimal ventilation and maximum heat transfer, ensuring optimal performance and efficiency.
Shutdown maintenance
Preparation before shutdown:
When the centrifuge is not used for a long time, it should be shut down for maintenance. This includes cutting off the power supply, cleaning the equipment, applying anti-rust oil, etc. to prevent the equipment from being corroded or damaged by moisture. Extend the lifespan of your centrifuge with proper maintenance. Keep your equipment clean and corrosion-free by regularly cutting off power, cleaning, and applying anti-rust oil.
Rotor treatment:
If the centrifuge is not used for a long time, the rotor should be removed and anti-rust oil should be applied to the rotor seat and drive shaft to prevent the rotor seat and drive shaft from rusting. Increase the lifespan of your centrifuge with our rust-prevention treatment. Simply apply anti-rust oil to the rotor seat and drive shaft when not in use for extended periods of time.
Precautions for use
Matching samples with centrifuge tubes:
When using a centrifuge, ensure that the chemical resistance of the centrifuge tube material matches the experimental requirements to avoid rupture or contamination of the centrifuge tube due to chemical reactions. Manufactured to meet rigorous standards, our high-quality centrifuge tubes ensure safe and efficient sample testing. With chemical resistance specifically matched to your experimental needs, you can trust that our tubes will withstand even the most reactive chemicals in your centrifuge. Avoid the risk of rupture or contamination and maintain the integrity of your experiment with our durable and reliable tubes.
Balanced placement of centrifuge tubes:
When installing centrifuge tubes, ensure that the centrifuge tubes are placed symmetrically to avoid imbalance that causes the centrifuge to shake or generate noise. To ensure optimal performance, proper placement of centrifuge tubes is imperative. By maintaining a balanced and symmetrical configuration, you can avoid potential issues such as shaking or noise, allowing for a precise and efficient separation of biological samples.
Through the implementation of the above daily maintenance measures, the stable operation and efficient separation performance of the centrifuge can be ensured, its service life can be extended and the failure rate can be reduced. With the right maintenance, you can count on consistent performance and a longer lifespan from your centrifuge. Enjoy more reliable performance and fewer breakdowns.
Setting of maintenance cycle
General recommendation:
Under normal circumstances, the maintenance cycle of the centrifuge is generally set to perform comprehensive maintenance once a year, and regularly clean, change oil, and overhaul the equipment. However, the setting of the specific maintenance cycle also needs to be comprehensively considered based on factors such as the frequency of use of the equipment, the use environment, the type and specifications of the equipment.
Flexible adjustment:
In actual operation, the maintenance cycle can be flexibly adjusted according to the specific situation of the equipment and maintenance records. For example, if the equipment has abnormal conditions or obvious performance degradation during use, maintenance and inspection should be carried out in advance; if the equipment is in good condition for a long time and the frequency of use is low, the maintenance cycle can be appropriately extended.
