Basic principle of connecting structure in instrumentation - Database & Sql Blog Articles

The basic principles of using a coupling structure in instrumentation are:

1) Ensure the requirements of the instrumentation for the strength and accuracy of the joint;

2) Ensure the reliability of the work of the parts under the conditions of use;

3) In order to simplify the structure, non-detachable joints should be used as much as possible;

4) Parts that need to be adjusted, repaired and replaced should be detachable;

5) When there are multiple joints in the part, usually the non-detachable joint is used for the first assembled part or the inner part; the rear assembled part or the outer part is detachably connected;

6) It should be ensured that the parts and connections assembled first and second will not affect each other;

7) Ensure that the parts are not deformed or deformed minimally during the joining process;

8) The less the specification of the coupling is used, the less the fine threaded joint is used.
