| 1¡¢Why will the water leak out from the water spray tube? |
| There are some reasons for this £º 1¡¢There is size difference among brass mouthpiece, outer bushing and inside of conduit . 2¡¢Connection between inside of conduit and brass mouthpiece is too small, It couldn¡¯t be stressed into the furrow of brass mouthpiece, so there is lack of hydraulic resistance 3¡¢Due to the unqualified inner tube (material with bubble), the inner tube is broken when press the brass mouthpiece 4¡¢The inner tubes are broken during the transportation (tiny holes), which were not found out in the inspection and production. |
| 2¡¢Why does the copper plug in the outlet end of the water spray tube get away easily? |
| There is one possibility£º 1¡¢The size of copper plug is out of the tolerance dimension, and couldn¡¯t connect with tube tightly. |
| 3¡¢Why there are flaws such as: sandy points, fillister points, protruding points, bubbles and plating peel-out? |
| There are some reasons for this£º 1¡¢The components were not cleaned completely before plating, there are impurities on the surface of components. 2¡¢ There are too many impurities in the plating liquid. 3¡¢ The polishing wax is not cleaned completely before plating. |
| 4¡¢Why does verdigris come out when carrying out G85 salt spray test for plated parts? |
| There are some reasons for this£º 1¡¢The pre-procedure is not progressed well enough for the part¡¯s dead corner. It is a little rugged which make the plating layer uneven. 2¡¢ Deformation of plate tools and unstable circuit make the plated layer to be uneven. |
| 5¡¢In the hydraulic test of the rotation connector, why it leak in low pressure , not in high pressure? |
| There are some reasons for this£º 1¡¢The ¡®V¡¯ shape washer in the connector deforms when pressed into connecting with plastic mouthpiece. 2 Hardness of the ¡®V¡¯ shape washer is too high, it make ¡®V¡¯ shape washer couldn¡¯t extend completely to connect with inner surface of nut when the hydraulic is low. The burr of the ¡®V¡¯ shape washer is too big, and it wasn¡¯t detected in the inspection and production. |
| 6¡¢Why will the hooks of the spray water tube get away? |
| There are some reasons for this£º 1¡¢The different width of the strip will lead to different hook border . 2¡¢Unstable frequency of the tube-forming machine will influence the throb of machine. Secondly, the abrasion of the tool will bring construction deformation. 3¡¢In the pressure test during production, the rotation force is too strong in the low hydraulic test, which makes construction deformed. |
| 7¡¢Why did the outer bushing get away from the tube when carrying out 1000 times tensile test? |
| There are some reasons for this£º 1¡¢ Size between thread gauge of outer bushing and the furrow of tube are different, so they couldn¡¯t match each other tightly. 2¡¢ Lack of glue, it leads to lack of cohesiveness. |
