4 General Requirements
4.1 General Requirements
4.1.1 All personnel involved in assembly should undergo three levels of safety education and on-the-job skills training. Those in special trades (crane operators, special equipment operators) should hold relevant certificates.
Only those with the corresponding qualification certificates are allowed to work, and operators of key processes and special processes must be trained and qualified before they can work.
4.1.2 Before assembly, all parts should be inspected to ensure that their models and specifications meet the requirements of the configuration list.
4.1.3 Before assembly, the parts entering the assembly area should be inspected. Assembly can only proceed if they meet the following requirements.
a) It bears a certificate of conformity after passing inspection;
b) Review the main mating dimensions and part numbers of key components and record them in the warranty card;
c) The mating dimensions adjusted by the fitter shall be re-inspected by the quality inspection department of the complete machine manufacturer and recorded in the warranty card.
4.1.4 Each assembly process should have an assembly process control card, which should be recorded and stored in the wind turbine generator set file.
4.1.5 Parts should be cleaned or washed before assembly and should be free of burrs, flaked edges, scale, rust, chips, oil, colorants, and dust.
Before assembly, sharp corners or high points on mating surfaces should be trimmed. Unless otherwise specified, sharp corners and edges of parts should be rounded off before assembly. (Assembly process...)
