Analysis of Anticorrosion Technology of High Speed ​​Refrigerated Centrifuge

The anti-corrosion technology of high-speed refrigerated centrifuge needs to be improved. It can be said that it is one of the widely used branch products in the centrifuge industry. Because of the wide application, there are many problems. The common problem is anti-corrosion, because the centrifuge needs to contact various kinds of All kinds of liquids, so it is very common to encounter corrosive liquids. Therefore, the anti-corrosion problem of high-speed refrigerating centrifuges is a major project, which requires the efforts of professionals in the centrifuge industry, technicians and major centrifuge manufacturers. Together, we will make more contributions to the development of the high-speed refrigerated centrifuge industry!

During the long-term operation of the high-speed refrigerated centrifuge, some moisture is immersed in the scoop pump and mixed with the oil. Therefore, in each inspection, the oil drain switch at the bottom of the vacuum pump should be turned over to discharge the water, and then the accessory funnel is punctured into the oil draining ethylene pipe, and is always added to the oil level to investigate the height of the intermediate marking line. I found that the oil was too dirty and black, and I should just release it for replacement. The high-speed refrigerating centrifuge is a powerful centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the sedimentation speed of the particles in the liquid, and separate the sedimentation coefficient and the buoyant density material in the sample.

The high-speed refrigerated centrifuge is not only a sample processing volume from a micro tube to a maximum of 4 x 200 ml, no carbon brush maintenance-free variable frequency motor, long service life, magnetic rotor identification, universal desktop refrigerated centrifuge, and extremely stable operation at the highest speed. Accurately adjust and display the speed, the speed range is 100 ~ 15300 rpm. A variety of horizontal and corner rotors are available to avoid over-speeding. The high-speed refrigerated centrifuge micro-controller can set the speed, time, temperature and centrifugal force. When the rotor is stationary, it can be pre-cooled, using R134a environmentally friendly fluorine-free refrigeration. 20 acceleration and deceleration curves (3k15) and 10 program memory functions

The organization planning of high-speed refrigerated centrifuges, an excellent plan can extend the service life of the equipment and ensure the safety of the equipment. The structural defects that are most likely to accelerate the corrosion of the planning are the stress gathering tendency and the gap environment, sometimes in the metal soaking solution. The corrosion rate is small; but it forms a gap because the chemical and electrochemical conditions of the internal solution change, which will lead to severe crevice corrosion. High-speed refrigerated centrifuges choose the right raw material centrifuges mainly because of different materials and different requirements, you need to choose a different model. After the model and the main parameters are determined, according to the corrosion resistance function of different materials in different environments, comprehensive physical and chemical special J students, cost performance and other factors are combined to determine the strength component data from the fundamental. From the point of view of the data itself, the target material it is about is safe.

The high-speed refrigerating centrifuge is equipped with various protections such as unbalance, overspeed, over-temperature and door cover to ensure the safe use of the instrument. It is equipped with a variety of rotors and is suitable for separation of medical centrifuges such as radioimmunity, biochemistry and blood products. The corrosion inhibitor centrifuge itself is used in many disciplines. It is necessary to use a high-speed refrigerated centrifuge. In addition to the above methods, you should also pay attention to the environment in which it is used. The use of corrosion inhibitors is also used in practice. For some harsh environments, the selection of appropriate corrosion inhibitors can make the parts reach the applicable level. As long as the technical agreement, the selection of corrosion inhibitors should be a useful way for the centrifuge.

A fundamental idea of ​​high-speed refrigerated centrifuges to control corrosion is to isolate the corrosive environment. In the planning of centrifuges, external treatment methods such as flange, galvanizing, chrome plating, and electroless plating are often used. These methods are useful in many environments, but for rotating parts, one must pay attention to a main scene: the substrate The data and the coating are two kinds of materials, and the coefficient of linear expansion is different. A different amount of deformation will occur when the rotating member is elastically deformed, and then the high-speed refrigerating centrifuge forms a lot of microcracks; if the aforementioned scene exists, Will accelerate the formation of corrosion. Therefore, the external protection measures for rotating parts should be carefully selected.
