liner running 中文意思是什麼
liner running
解釋
下尾管-
Company has expertise on multi - lateral well, rotating liner hanger cementing, geosteering, vertical drilling, dexpandable pipe, casing open window, verious completion, repairing, incident handling, special tubing running, special connection maching and so on
有能力進行分支多底井、旋轉尾管固井、地質導向、防斜打直、膨脹管、套管開窗，各種完井、修井、事故處理、特種油管套管下入、特種絲扣加工等。 -
If the using abrasion speed is low and the loading is not very big, but it undertakes heavy impact when running, it is better to apply thick wall shaft liner, for if the wall is too thin, the rigidity is not enough
如果使用滑動磨擦速度較低，負載不是很大，但運轉時受很大的沖擊，此時應採用厚壁軸套。如果軸套壁薄，剛度不足，可與金屬外套復合使用。 -
The shaft liner only works intermittently, when it stops running, it generates no heat, but the radiation is continued
軸套只做間歇式工作，在停止工作這段時間內並不產生磨擦熱，但散熱仍在進行。 -
The working condition of nylon shaft liner is determined by many factors, for example : the different formula, shaping technique, the design of shaft liner, installation method, loading features, running speed, lubricant condition, the working environment of shaft liner temperature, humidity and the influence of impurity, abrasion when working etc. so, when designing shaft liner, it is necessary to take consideration of all conditions
鑄型尼軸套的許用工作情況是由很多因素決定的，例如不同配方和成型工藝所制得的材料物理機械性能，軸套的設計裝配方法，負載特點，運轉速度，潤滑情況，軸套的工作環境溫度濕度雜質的影響，工作時的摩擦條件，對磨材料的性能等。因此，在設計軸套時，應綜合考慮各個方面的因素。 -
In order to achieve effect running without fault, the max running pv value should be limited in 0. 220. 24 ; under oil lubricating circulating or the shaft liner runs in oil, the max running pv value reaches 2. 5 even above, for the radiation is fine
為保證使用中不出現問題並有效的工作，應控制最大許用pv值在0 . 220 . 24之間在有循環油或者軸套在油中使用時，最大許用pv值可提高到2 . 5甚至2 . 5以上，因為這種情況散熱情況良好。 -
At this time, the temperature of the shaft liner will reduce gradually, if the working time is shorter than the running time, the heat rising is low and the pv value is high
此時，軸套的溫升就逐漸下降。如果工作時間短於停止時間，則蓄熱少，溫升低，許用pv值就高些。
