It is also equipped with operation instructions, certificates and inspector seals to guide users to use and maintain. Be careful to identify when purchasing to prevent buying fake and inferior products.

2.查看幾何尺寸是否變形。由于制造、運輸和儲存不當，一些零件容易變形。檢查時，可將軸類零件沿玻璃板滾動一次，看零件與玻璃板連接處有無漏光，判斷是否彎曲。

2. Check whether the geometric dimensions are deformed. Some parts are easy to deform due to improper manufacturing, transportation and storage. During the inspection, the shaft parts can be rolled along the glass plate once to check whether there is light leakage at the connection between the parts and the glass plate and judge whether they are bent.

3.查看接頭的位置是否平坦。在備件的搬運和儲存過程中，由于振動和碰撞，接頭處經(jīng)常會出現(xiàn)毛刺、壓痕、損壞或裂紋，這與備件的使用有關。采購注意事項檢查。

3. Check whether the position of the connector is flat. During the handling and storage of spare parts, due to vibration and collision, burrs, indentation, damage or cracks often appear at the joints, which is related to the use of spare parts. Inspection of procurement precautions.

4.查看零件表面是否有腐蝕。合格備件的表層具有要的精度和光澤。備件越重要，精度越高，防銹防腐包裝越嚴。購買檢查時的注意事項，如果發(fā)現(xiàn)零件有銹斑、霉斑或橡膠零件開裂失去彈性，或軸頸表面有明顯的車削刀痕，應更換。

If the seal sleeve is damaged, the wrapping paper is lost, and the rust preventive oil or paraffin is lost when purchasing, it should be returned.
