One of the basic ideas for controlling corrosion is to isolate the corrosive environment. In the design of centrifuges, surface treatment methods such as flange, galvanizing, chrome plating, electroless plating, composite lining, etc. are often used. These measures are effective in many environments; but for rotating parts, one must also pay attention to an important Phenomenon: the base material and the coating are two materials, and the coefficient of linear expansion is different. These structures will produce different deformation amounts when the rotating member is elastically deformed, thereby causing a large number of microcracks and peeling of the composite surface; The presence of the aforementioned phenomenon will accelerate the formation of corrosion. Therefore, the method of surface protection for rotating parts should be used with caution.
2 corrosion inhibitor
The centrifuge itself involves multiple disciplines. To use the centrifuge, in addition to the above measures, it should also pay attention to the application environment. The application of corrosion inhibitors is also widely used in practical applications. For some harsh environments, the use of appropriate corrosion inhibitors can make the parts suitable. As long as the process permits, the use of corrosion inhibitors should be an effective way for centrifuge applications.
3 correct process
The design is correct and the material selection is reasonable. It is only the precondition for solving the corrosion of the centrifuge; the correct application of the processing technology also affects the anti-corrosion ability of the centrifuge to some extent. Processing methods usually leave many defects on parts or equipment, such as misalignment, local stress, etc.; misalignment may cause gaps; improper positioning method may lead to eccentricity of parts; unreasonable pass may result in surface roughness; Appropriate, welding, heat treatment methods or measures are unreasonable, and the uneven force of the fastening bolts will cause local stress concentration. Therefore, finding the right process is also an effective way to prevent corrosion.
The corrosion problem of the centrifuge is a comprehensive and complex problem, because the working environment of the centrifuge is quite different from the data obtained by the general information and manual in the static. Therefore, in addition to the above analysis, in addition to the above analysis, consideration should also be given to the effects of dissolved oxygen, temperature, high-speed fluid and fluid state changes in the separation zone, and appropriate measures to ensure safe and reliable operation of the centrifuge.
Oxygen Cylinder Filling System
With PSA principles, ETR Oxygen Cylinder Filling system can produce 93%±3% purity oxygen gas from compressed air directly. ETR oxygen cylinder filling system is consisted of Atlas screw air compressor, refrigerated air dryer, compressed air filter, air buffer tank, ETR Oxygen Plant, oxygen buffer tank, oxygen booster, cylinder filling station and HMI control cabinet.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure. With an oxygen booster, the oxygen pressure can be to 150bar and fill in cylinders.
