1.The assembly parts itself must meet the technical requirements, any unqualified parts can't assembly.For this parts must pass strict inspection before assembly.

2.Must choose the right method to meet the demand of the matching accuracy.Mechanical seal repair is to restore the large amount of work of mutual cooperation with precision, can adopt methods such as matching, and replacement, adjustment to meet this requirement.Fit clearance needs to consider the effect of thermal, for by the different expansion coefficient of material composition of mating parts, when the assembly of the ambient temperature to the work when the temperature difference is bigger, the resulting gap change should compensate.

3.To analyze and check the accuracy of assembly dimension chain, through the selection and adjustment to meet the accuracy requirement.

4.Handle parts assembly sequence, its principle is: after the first, difficult before they are easy, first commonly after precision.

5.Choose the suitable method to assembly and assembly equipment, tools.

6.Pay attention to cleaning and lubrication of the parts.A thorough cleaning, assembly parts must first to move with a clean coating on the surface of the relative motion of the lubricant of conform to the requirements of the job.

7.Pay attention to the assembly of the mechanical seals, prevent the "three leakage".To adopt rules of seal structure and seal material, can't use any substitute.Attention should be paid to the quality of the sealing surface and clean.Pay attention to the assembly method and fitting degree of seals, for static seal can adopt proper sealing glue sealing.

8.Pay attention to the assembly requirements locking device, in accordance with safety rules.

9.Attaches great importance to the assembly of the intermediate links of quality inspection.
