One of the headaches of industrial hydraulically driven centrifuges is that the centrifuges are used for chemical raw materials for a long time, which leads to the corrosion problem of the centrifuges. Here are four measures to prevent or slow down centrifuge corrosion.

Choosing the right hydraulically driven centrifuge for the material is important because different materials and separation requirements require different models. After determining the model and main parameters, according to the corrosion resistance of different materials in different environments, and considering many factors such as physical and chemical properties, cost performance, etc., the strength parts materials are determined from the basic aspect. From the material itself, the target material is safe.

Secondly, the mechanism design of the centrifuge, the strong design can prolong the service life of the equipment and ensure the safety of the equipment. For structural design, the design defects that are easy to accelerate corrosion are stress concentration tendency and crevice environment. Sometimes the corrosion rate is small even though metal is immersed in the solution; but the formation of cracks and the change of chemical and electrochemical states of the internal solution will cause Severe crack corrosion.

Surface protection measures for hydraulically driven centrifuges

One of the basic ideas for controlling corrosion is to isolate the corrosive environment. In the design of centrifuges, surface treatment methods such as flanges, galvanizing, chrome plating and chemical plating are often used. These methods are effective in many environments, but for rotating parts, an important phenomenon must be paid attention to: the substrate and the coating are two materials with different coefficients of linear expansion, and different deformations will occur when the rotating parts are elastically deformed, A large number of microcracks are produced; if the above phenomena are present, the formation of corrosion will be accelerated. Therefore, surface protection methods for rotating parts should be used with caution.

The use of corrosion inhibitor centrifuges involves multiple disciplines. In order to make better use of the centrifuge, in addition to the above measures, attention should also be paid to the study of its application environment. The application of corrosion inhibitors is also widely used in practical applications. For some harsh environments, proper corrosion inhibitors can make parts suitable. As long as the process allows, the use of corrosion inhibitors should be an effective way to apply the centrifuge. Through the above four points, the centrifuge can be well protected and more resistant to corrosion, making the centrifuge last longer and safer.
