Due to the application occasion and particularity, the production management and product requirements of explosion-proof motors are higher than those of ordinary motors, such as motor tests, parts materials, size requirements and process inspection tests.
First of all, explosion-proof motors are different from ordinary motors because they belong to the scope of production license management of industrial products. The country will adjust and release the catalog of production license management products in due course according to the actual situation. The product manufacturers in the corresponding catalog must obtain Only the production license issued by the national competent department can be produced and sold; and the products outside the scope of the catalog do not belong to the scope of production license management, which is also some doubts in the bidding process of motor products.
Particularity of component design and production process control. The matching dimensions of explosion-proof motor parts are longer than those of ordinary motors, and the matching clearance is relatively small to meet the explosion-proof requirements during the operation of the motor; therefore, in the actual production, processing and maintenance of the motor, ordinary motor parts cannot be simply used for explosion-proof motors; and for some parts, the compliance of their performance should be evaluated through hydraulic tests during production and processing. Therefore, the casing material of explosion-proof motors also has specific regulations.
The difference in machine inspection. Supervision and random inspection is one of the means of quality evaluation of motor products. For ordinary motor products, the focus of inspection is the conformity of their installation dimensions and performance indicators of the whole machine. The inspection, that is, the compliance inspection of the explosion-proof surface. In recent years, in the random inspection process of the whole machine at different levels, the conformity of the explosion-proof surface has always been the item with the most problems found among the motors that have been inspected. Insufficient, and when some parts are purchased for production organization, the quality control is not in place.
Assembly fixed specificity. For the assembly and fixing of key parts, especially the fasteners of the wiring system, there are also specific regulations on the screw-in length of the thread, including that the screw holes in special parts can only be blind holes, which is a special requirement in the processing of explosion-proof motor parts. Concerns.
