請教發電機油頭研磨技巧

版上各位前輩們好
小弟目前保養的是(瓦錫蘭)warsila 6L20系列的發電機,對於研磨換下的油頭沒什麼經驗,請教一下對於這方面有經驗的前輩們,能否給小第一些指導,目前碰到兩個問題:
(1)研磨出來的油頭底部會出現一條細白線,但都打不亮
(2)磨完去試壓,霧化OK但壓力有些不足

或者有前輩知道哪些相關書籍提到這類的知識,也請不吝告知書名,再次感謝各位前輩

沒記錯的話，那一圈是細線。
另外接油管泵壓的地方，會有一
個螺栓讓你作壓力調整。一邊泵，
一邊調。不要有垂流的現象是最好的!
並且檢查噴孔有無堵塞，如有以通針
處理。說明書應該會有寫到才是，參
考看看!!!至於細部還需請有經驗的
前輩再詳細的解說。

各位輪機弟兄:應該可以交由岸上處理,不必把自己搞得太累,行嗎?

沒辦法,長官要求,但多學一樣東西也是不錯啦,感謝版上前輩的回覆

再補充一下
在做噴油器噴油壓力調整時，若發現噴油器有滴油現象，或者在做噴油器保壓試驗時發現噴油器有滲漏現象，說明針閥偶件密封性不良，應重新做零件研磨將零件從噴油器裡拆出，在輕柴油或汽油裡清洗乾淨．在閥針的錐面上塗些許氧化鉻研磨膏，插人針閥座內用手捻動研磨，直到在閥針錐面上能看到一個完整而等寬的黑色環帶為止。重新清洗乾淨，裝復再試，直至無滴油和滲漏。如果不能得到完整的研磨帶，或帶寬邊緣不整齊、研磨帶凹陷、局部研磨印跡模糊，都必須換用新零件。研磨時應注意，不要讓研磨膏落到針閥的導向柱面上，以免研壞導向段。

Cone at the needle valve a little chromium oxide coated abrasive paste, insert the needle valve seat grinding by hand twisting action until the valve needle cone to see such a complete and broad black band up. Re-cleaned, refitted and try again, until no dripping and leakage. If you can not get the complete grinding zone, or bandwidth, irregular edges, grinding with depression, local ground blot fuzzy, must be changed even with the new pieces. Grinding should be careful not to fall into grinding paste guiding needle cylinder so as to avoid the bad research-oriented segment.
