to ensureLarge capacity centrifugeThe operational safety can be considered and operated from the following aspects:
1、 Preparation and inspection before operation
1. Placement environment: Ensure that the worktable of the centrifuge is flat and sturdy, and that the workspace is kept tidy, clean, ventilated, and dry. In addition, the installation location of the centrifuge should be stable, with a flat and firm ground to ensure the normal operation of the rotor.
2. Power supply inspection: Ensure that the voltage fluctuation of the power supply is within+10%. If the voltage fluctuation is large, it is recommended to use a voltage regulator. At the same time, the grounding wire must be firm and not connected to the heating pipe or water pipe.
3. Rotary head inspection: Before operation, the rotary head should be checked for corrosion damage and ensure that the rotor is installed correctly.
4. Sample loading:
The sample container should be sturdy, able to withstand centrifugal force, and a suitable shock-absorbing pad should be placed between the centrifuge tube and the container.
Avoid placing heavy or oversized samples on the centrifuge to prevent damage to the centrifuge.
When installing the sample, try to maintain balance and avoid unbalanced forces impacting the bearings and brackets.
2、 Precautions during operation
1. Slowly open and close the centrifuge cover: When opening or closing the centrifuge cover, operate slowly to avoid collision between hands or other body parts and the centrifuge.
2. Cover the centrifuge cover: During operation, make sure to cover the centrifuge cover to prevent sample evaporation and leakage.
3. Prohibit opening doors during operation: During the operation of the centrifuge, it is strictly prohibited to open the centrifuge cover to avoid accidents and damage to the centrifuge.
4. Pay attention to observation: During operation, pay attention to the operating status of the centrifuge. If there are any abnormalities, stop the machine for inspection in a timely manner.
3、 Maintenance and upkeep after operation
1. Cleaning up accumulated water and drying: If the refrigeration function is used during the operation of the centrifuge, frost will form inside the centrifuge chamber. After shutdown, the frost will turn into water. It is necessary to remove the rotor in a timely manner to clean the accumulated water and dry it with a hair dryer to ensure that it is dry before use.
2. Regular maintenance and upkeep: Regular maintenance and upkeepLarge capacity centrifugePerform maintenance and upkeep, keeping it clean and dry to ensure its normal operation.
3. Follow safety guidelines: When handling samples, be sure to follow the laboratory's safety and hygiene guidelines to ensure the safety and hygiene of the operation process.
4、 Other safety measures
1. Equipped with safety devices: Centrifuges should be equipped with safety devices such as protective covers, emergency braking devices, and safety interlock systems to ensure timely shutdown in case of abnormal situations and protect the safety of operators.
2. Professional training: Operators should undergo professional training and pass the assessment before taking up their posts to ensure that they are familiar with the operating procedures and safety precautions of centrifuges.
3. Regular inspection and replacement of components: Key components of the centrifuge should be inspected regularly, such as the drum, which must be replaced every 3000 hours of operation or 500 cumulative starts. The insulation resistance of the electrical system should be checked quarterly to ensure the safety performance of the centrifuge.
By preparing and inspecting before and after the operation, paying attention to safety precautions during the operation, strengthening maintenance and upkeep after the operation, and taking other safety measures, it can be ensured thatLarge capacity centrifugeSafe operation.
