1. The protective performance of the equipment should be targeted. Such as whether it is in contact with corrosive media; whether there is mechanical wear; what load it bears; what environment it is installed in; what is the appearance of the instrument, and so on.
2. There are absolutely no materials and protective layers that will not be eroded. Therefore, the materials and protective layers used on the instrument must be considered to what extent they are allowed to be eroded when subjected to erosion. For testing instruments, such as the corrosion of the steel beam on the plasticity instrument by the cylinder compression method, it will affect the elastic limit and thus affect the accuracy of the plasticity index determination.
3. To solve the protection problem of the instrument, you can start from three aspects: selecting protective materials, taking protective layer technological measures and improving the structure of the instrument.
4. The installation position of the instrument should be improved as much as possible. If it can be installed indoors, it is not installed outdoors; if it can be installed in a cool and dry place, it is not installed in sun exposure, wet and dark places, etc.
5. In order to protect the accuracy of the instrument, the instrument should not be protected by isolator or other isolation devices.
6. Saving is one of the basic principles of the socialist economy. To solve the protection problem of the instrument, it is also required to achieve good protection performance, but also to achieve the economical and reasonable principle of saving materials locally and simply.
