The correct use of high-speed large-capacity centrifuge

The correct use of high-speed large-capacity centrifuges is a precondition to ensure the normal operation of the centrifuges, and is also an important factor in extending the life of high-speed large-capacity centrifuges. Therefore, when we use high-speed large-capacity centrifuges, we must ensure that the high-speed large-capacity centrifuges are operated correctly. However, even if it is operated correctly according to the instructions, there will be operators who say that the instrument is hot. So, what causes the temperature rise of the high-speed large-capacity centrifuge shell?

During the operation of the high-speed large-capacity centrifuge, it is normal that the high-speed large-capacity centrifuge to generate heat. The high-speed large-capacity centrifuge needs to consume a certain amount of electrical energy when it is running, and the electrical energy is converted into the mechanical energy of the high-speed large-capacity  centrifuge when rotor works, the energy is inevitably lost during the conversion process. Part of the energy will be converted into heat and emitted, so that the high-speed large-capacity centrifuge will heat up. However, if the parts of the high-speed large-capacity centrifuge are overheated, it means that too much electrical energy is converted into heat energy and lost. So, what is the cause of this situation?

The first reason: may be that the high-speed large-capacity centrifuge is overloaded, which will cause the current to become larger, the rated power is greater than the actual power, and the excess part is converted into heat and dissipated, which will make the parts of high-speed large-capacity centrifuge are overheating.

The second reason may be caused by the high power of the high-speed large-capacity centrifuge. If the actual power required by the high-speed large-capacity centrifuge is so large, then the excess part will be lost and converted into electrical energy.
The third reason is the problem of high-speed large-capacity centrifuge setting or starting device. The energy conversion rate is low when the high-speed large-capacity centrifuge is started. If the high-speed large-capacity centrifuge is set too fast or there is a problem with the starting device, can be made the high-speed large-capacity centrifuge power is too large, but the energy conversion rate is too low. If the parts of the high-speed large-capacity centrifuge are overheated, the service life of the components of the centrifuge will be greatly shortened. At this time, it is necessary to find out the cause of the failure of the high-speed large-capacity centrifuge in time and deal with it in time, when necessary you can contact the manufacturer of high-speed large-capacity centrifuges for professional troubleshooting and maintenance.
In fact, it is very dangerous that an accident occurs after the high-speed large-capacity centrifuge starts to work. The high-speed rotating rotor flies out and can penetrate almost everything.In this situation, the correct use of high-speed large-capacity centrifuges is the top priority.

The maintenance of high-speed centrifuges is also very important. High-speed large-capacity centrifuges need to be maintained regularly after continuous use, and regular inspections are also required.

How to maintain a high-speed large-capacity centrifuge? In fact, daily maintenance starts with methods and steps. To check the high-speed large-capacity centrifuge, you must check the parts after the instrument is stop working. The power must be cut off before the instrument is checked, and then try to move the drum by hand to see if there is any seizure. Check whether there is any looseness or abnormality in other parts. You can turn on the power and start driving in a clockwise direction. Generally, it will need about 40-60 seconds enter normal operation from a static state. The new instrument needs to run empty for about 3 hours before normal use, and it can work without any abnormalities. When placing the test tube、centrifuge tube and other containers, be sure to place it as evenly as possible, otherwise the instrument will shake violently.

The operation of the high-speed large-capacity centrifuge must be carried out by the dedicated staff. Remember that the capacity should not exceed 2/3 of the rated capacity. In order to avoid affecting the service life of the machine, it is strictly prohibited to operate the machine at excessive speed or work continuously for a long time. Once the machine is turned on, if there is an abnormality, it should be stopped for inspection immediately, and if necessary, contact the dedicated person for maintenance. When the high-speed large-capacity centrifuge is operating at high speed, you must remember not to touch the drum with your body to avoid accidents.

To ensure the normal operation of the high-speed large-capacity centrifuge, the rotating parts must be refueled and maintained every 6 months. And at the same time, check the lubricity of the bearing to see if there is any wear. In particular, the wear of the components of the brake device needs to be replaced in time if it is serious.
After the centrifuge is used, the corresponding cleaning work must be done to keep the high-speed large-capacity centrifuge clean and tidy. Remember not to use the non-corrosive high-speed large-capacity centrifuges to separate the highly corrosive materials. It is necessary to operate strictly accordance with the equipment use requirements and regulations. The service life of the centrifuge can be prolonged if do good job of maintenance.
