钻机修井机设计使用中几个容易混淆的问题——系列专题之八

Sum confused questions on the design and application of drilling rig and workover rig——Special topic Sec Ⅷ

钻机修井机设计和使用中存在一些模糊不清的问题,例如,最大钩载和钩载储备系数,柴油机功率选配,效率、功率利用率和功率因数,钻井泵的转向问题等;在钻机使用中是否允许超过公称钩载,功率是否配得越大越好?这些问题都需搞清楚,否则会造成不必要的浪费和危害。

This article will clear up the confused questions on the design and application of drilling rig and workover rig. Such as maximum hook load and load store coeficient, power dispose of diesel engine,efficiency,power utilization ratio and power factor,the rotate direction of mud pump etc. In practical operation is it allowed for the rig to work over load？ The higher power will be right？ Such question must be cleared up, otherwise it will bring about.unnessary waste and harm.
