As a common separation instrument in laboratories, centrifuges can be divided into low-speed centrifuges, high-speed centrifuges, and ultra fast centrifuges according to their rotational speed; According to temperature, it can be divided into cryogenic centrifuge and room temperature centrifuge; According to capacity, it can be divided into micro centrifuge, large capacity centrifuge, and large capacity centrifuge; According to their appearance, centrifuges can be divided into desktop centrifuges and floor standing centrifuges. The most important thing when using a centrifuge is safety. If the centrifuge loses control, it can cause significant damage. Therefore, it is necessary to balance the centrifuge. So, what are the consequences of not balancing the African swine fever detection centrifuge?
Even low-speed centrifuges can be shut down in a timely manner without major accidents, but they may damage the shaft. You should know that the expensive part of a centrifuge is even if it has a rotating shaft. How expensive is it? That kind of freeze centrifuge, once it was not balanced and damaged the shaft. The leader called the after-sales service, and when the customer service quoted the price, the leader's face turned green
Some centrifuges are equipped with detection devices, and if the balance is not qualified, it will automatically terminate. Previously, this feature was only available in foreign centrifuges, with very few in mainland China. Now, there are also better machines available in mainland China. However, it will still damage the shaft. Once the pivot is damaged, everyone can watch the leader perform Sichuan opera - face changing.
Do you have a concept of the rotational speed of a centrifuge? Generally, laboratories use around 20000r/min, while high-speed centrifuges can reach 50000r/min. That is to say, a piece of iron weighing over ten kilograms rotates at a speed of tens of thousands of kilometers per minute, but what is the speed of a chainsaw? About 5000.
A low-speed centrifuge, approximately 2000-3000 revolutions per minute, is not well balanced, and the lower bracket is not too sturdy. So during centrifugation, the vibration was significant and gradually deviated from its original position. That noise was like a large cabinet carrying a lot of kitchen utensils suddenly being thrown to the ground. Fortunately, there was no one in this room at that time.
There are still many old-fashioned centrifuges in laboratories that do not have self stopping detection functions installed. Once there is no balance, the rotor may fly out, and once the rotor flies out, it may cause injury accidents. So, when using the African swine fever detection centrifuge, remember two words! Balance it out!
