Shenhai Explosion-Proof
Tom qab segmenting lub rooj sib txoos units raws li kev tsim kho blueprints, cov kab ke ntawm kev sib dhos tuaj yeem txiav txim siab.
Cov kab ke no feem ntau pib nrog ib tus neeg thiab cov khoom sib txuas thiab ua tiav hauv kev sib dhos zaum kawg. Lub Rooj Sib Tham System Chart (Daim duab 7.6) graphically sawv cev rau cov kev sib raug zoo thiab cov kab ke, providing a clear overview of the entire assembly journey from the initial stages to the final assembly.
Similar to the assembly process card, the Assembly System Chart serves as a documented format of the assembly process specifications.
When setting the assembly sequence, attention must be paid to potential challenges. Even after analyzing parts and components for structural assembly feasibility, an impractical sequence can complicate the process. Piv txwv li, fitting one component in a deep casing first might hinder the installation of subsequent components, even if the structural assembly is technically feasible. ‘Interference’ occurs when a part or unit doesn’t physically interfere in the diagram but becomes unassembleable due to an inappropriate assembly sequence. This scenario is not uncommon in assemblies with complex structures.
The unit diagram, guided by the numbering on the equipment’s engineering drawings, should clearly label each unit with its name, drawing number, and quantity. This labeling aids in easily identifying the necessary parts, cov khoom, kev sib koom ua ke, and their quantities during assembly.
It’s also important to annotate purchased items used within parts, cov khoom, and assemblies in the unit diagram, specifying their name, qauv, specification, and quantity.
The Assembly System Chart is generally employed for single or small batch productions. Txawm li cas los, in large-scale production scenarios, it should be used alongside the assembly process card for optimal efficiency.
