The key to the safety of centrifuge is the safety of motor rotor
Centrifuge is a kind of new scientific and technological instrument and equipment in laboratory, which is also widely used. It can be used as a reference in many aspects when the centrifuge model is selected. Centrifuge is a kind of special instrument and equipment, and there are certain safety risks in the application. Therefore, it is particularly important to ensure the safety of mechanical equipment and users of centrifuge! The key to the safety of centrifuge is the safety of motor rotor.
Pay attention to the following aspects when purchasing centrifuges:
First, pay attention to the purchase of imported bearings.
Centrifuges belong to high-speed rotating chemical machinery and equipment. High speed rotation requires good bearings. High quality and pure bearings can ensure the long-term normal operation of centrifuges. The service life of centrifuges can be as long as more than 10 years.
Second, we should pay attention to the persistent lubrication of mechanical equipment, and use high-quality high-temperature lithium grease. The good or bad quality of lithium grease is another key reason for bearing heating. In addition, it should be checked according to your delicate condition, assuming that the friction of mechanical equipment will be accompanied by noise, and the mechanical parts will be significantly damaged. If you feel that the bearing is loose, then it should be a difficult problem for the bearing to be replaced.
Third, the centrifuge spindle bearing concentricity can be accurate, under all normal conditions, we do not pay much attention to concentricity, spindle bearing concentricity tends to be large, easy to form bearing heating.
Naturally, here we analyze the key reasons. There are also some reasons that users should be more careful.
Safety application regulations of centrifuge:
1、The model selection should be appropriate.
2、Centrifuges should be used according to the specified scope. Centrifuges for general use should not be used in places with inflammable and explosive materials or corrosive materials.
3、Operate in accordance with the specified safety operation procedures. Do not operate the abnormal braking system, overload operation and speed limit operation.
4、The failure detection should be carried out immediately. The centrifuge with common failure should not be operated, and the invalid centrifuge should be damaged immediately.
5、Install, apply and maintain the centrifuge according to the provisions of the commodity manual. Do not change the parts of the centrifuge or increase the speed ratio of the centrifuge.
6、Formulate and strictly abide by the relative management system of centrifuge installation, application and maintenance, so as to achieve the goal of safe application.
The heating of the components of the centrifuge is normal, because the application consumes some kinetic energy, but if it is too hot, then pay attention to it, check whether there is a problem, and properly handle it, so that the centrifuge can be used very well. With the popularization of centrifuges, a large number of manufacturers and users pay attention to the product quality of centrifuges, which is also a very good cooperation between manufacturers and users, so that the effect of centrifuges can be completely revealed.
