Common faults and treatments of disc centrifuges
Disc centrifuges play an important role in scientific research and production. However, due to their complex mechanical structure and high-speed operation characteristics, some faults often occur. The following are some common faults of disc centrifuges and their treatment methods:
Unable to start
Fault manifestation: After pressing the start switch, the centrifuge has no response.
Possible causes:
1. Power failure: the plug is not plugged in tightly or the socket is abnormal.
2. The power line is damaged or the power is off.
3. The fuse is blown.
4. Motor or controller failure.
Treatment method:
1. Check the power plug and socket to ensure that the power supply is normal.
2. Check whether the power line is intact. If there is damage or power failure, replace or repair it in time.
3. Check whether the fuse is blown. If necessary, replace it in time.
4. If the above steps are normal, it may be a motor or controller failure. Contact the manufacturer or professional maintenance personnel for repair.
Unstable speed
Fault manifestation: The centrifuge speed fluctuates and cannot reach the preset speed.
Possible reasons:
1. Poor centrifuge balance: sample tubes or centrifuge discs are not evenly distributed.
2. Mechanical failure: such as bearing wear, looseness, etc.
Treatment method:
1. Check whether the sample disc or centrifuge tube is evenly distributed, reload or distribute the sample to ensure balance.
2. If the problem persists after the balance adjustment, it may be a mechanical component failure, and you need to contact the manufacturer or professional maintenance personnel for inspection and repair.
Excessive noise
Fault manifestation: The centrifuge makes excessive noise or abnormal sound during operation.
Possible causes:
1. The bearing is worn or damaged.
2. The mechanical parts are loose.
Solution:
1. Stop using the centrifuge and check whether the bearing is worn or damaged. If necessary, replace the bearing.
2. Check whether the mechanical parts inside the centrifuge are loose. If so, tighten them in time.
