In Addition To Maintaining A High-speed Refrigerated Centrifuge, You Must Know The Core Component Motor

High-speed refrigerated centrifuges are also common equipment in research and test units, and are mainly used to separate difficult materials.

For example, common high-speed refrigerated centrifuge separators have the following two characteristics:

1. A suspension with a small solid content.

2. Low concentration, small particle size, high viscosity, solid medium with small difference in specific gravity between the two media.

Because these substances belong to a class of poor separation, the requirements for speed are relatively high, and because of the influence of some additional conditions, temperature requirements may be involved, so a high-speed refrigerated centrifuge has emerged.

In order to meet the experimental needs, the high-speed refrigerated centrifuge has to improve the speed, and the speed increase will have a direct impact on the motor.

Therefore, in the process of using high-speed refrigerated centrifuge, the maintenance of the motor is very important. For example, the common maintenance method is to replace the carbon brush after the motor is used for 3000 hours, so as to avoid wearing the commutator.

Of course, in addition to maintaining the motor of the high-speed refrigerated centrifuge, it is important to understand the problem of motor heating, prevent it in advance, and not overheat the motor. Here are a few simple reasons for the heating of the motor:

1. It may be that the high speed refrigerated centrifuge has a high speed, which causes its motor to easily heat up. If the motor of the high-speed refrigerating centrifuge is heated, it is necessary to pay attention to the operation of the high-speed refrigerating centrifuge, which is likely to be related to the heating of the motor bearing.

2. Centrifugal overload or overload, maybe there is a problem with the cooling fan, and the heat generated by mechanical friction. It is possible that the bearing of the high-speed refrigerating centrifuge is not genuine. Therefore, the user must choose the authentic genuine bearing, and some brands have different origins. Quality may also be different.

3. Pay attention to the smoothness of the machine. It is necessary to choose a high-temperature lithium base grease. The quality of the lithium base grease is also a major cause of bearing heat.

4. It is very important that the spindle concentricity of the high-speed refrigerating centrifuge is accurate. Under normal circumstances, the concentricity will not be noticed. The tendency of the spindle concentricity will form the bearing heat.

The above are some of the reasons for the heat of the high-speed refrigerated centrifuge motor, and there are some secondary reasons. If the user does not pay attention to the balance, etc., the motor will be heated. Therefore, in addition to choosing a good centrifuge, you should also pay attention to the usual habits.

Well, because of the limited space, today we will briefly explain the basic technical knowledge of high-speed refrigerated centrifuges.
