杆柱脱落Rodshedding杆柱脱落也是螺杆泵常发生的一种故障现象,表现为运行电流很低,井口也无产液,正反循环油套不连通,通过对扣或下入抽油杆打捞工具就可以进行处理来***生产。抽油杆脱落也有两种情况,一是脱扣,一是掳扣。造成脱扣的原因是停机后抽油杆柱扭转变形余能释放引起杆柱反转,可以采取在地面和抽油杆柱上安装防倒装置进行防止。造成杆柱掳扣的原因有三个:一个是稠油井在长时间关井后再启泵时,启动扭矩特别大,把螺纹损坏了;一个是油特别稠,螺杆泵长期在高扭矩下工作而把螺纹损坏;再有一个原因是定子部分脱胶,转子转不动造成的。定转子过早磨损Prematurewearoffixedrotor定转子过早磨损主要是由于定转子的间隙过小引起的。Theprematurewearofthefixedrotorismainlycausedbythe***allgapbetweenthefixedrotorandtherotor.油管与抽油杆柱磨损Oilpipeandrodstringwear油管与抽油杆柱磨损的原因一是因为井斜抽油杆贴在油管壁上引起的,可以通过加抽油杆扶正器使抽油杆柱居中来减轻或消除,另一个原因是定转子不同心及转子的偏心运动造成的,在定子以上加一节内径较大的回转筒即可避免。Tubingandsuckerrodwearreasonisbecausethedeviationofsuckerrodattachedtothetubingwallcausedbyheating,pumpingrodcentralizermaketherodcentertoreduceoreliminate,anotherreasoniscausedbytheeccentricmotionoftherotorandtherotorarenotconcentric,***oidadaythediameterofrotarycylinderinthestatorcanbelargerthan.A、定子A,stator定子是螺杆泵的一个关键部件,并直接影响到井下机组的寿命。定子制造质量越高,井下机组的寿命就越长。定子的作用就是提供转子工作和液体抽汲的螺旋腔,其结构非常简单,由钢制外壳和塑料/橡胶衬套内腔有双螺旋、三螺旋、四螺旋甚至五螺旋、六螺旋,在相同尺寸下,螺旋数越多,泵的排量越高。Thestatorisakeycomponentofthescrewpump,whichdirectlyaffectsthelifeofthedownholeunit.Thehigherthequalityofthestator,thelongerthelifeofthedownholeunit.Theroleistoprovidearotorstatorandliquidpumpingspiralc***itydrain,thestructureisverysimple,asteelshellandaplastic/rubberbushingc***itywithdoublehelix,threehelix,fourorevenfive,sixspiralhelicalspiral,inthesamesize,thenumberofspiral,thedisplacementofthepumpishigh.E、抽油杆扶正器E,suckerrodcentralizer抽油杆扶正器由心轴和扶正筒组成,它接在两根抽油杆之间,被卡在两个抽油杆接箍之间。心轴也就是一要极短的抽油杆短节。扶正筒是一个内孔比心轴大1MM左右的空心塑料筒,外部有四个略比油管内径小的扶正翼,采取浇注成型。扶正筒可以围绕心轴转动,防止抽油杆旋转时与内壁接触而磨蚀油管,又可以让流体通过。Thesuckerrodcentralizeriscomposedoftheheartshaftandtheuprightcylinder,whichisconnectedbetweenthetwosuckerrodsandisstuckbetweenthetwosuckerrodhoops.Theaxisoftheheartisalsoanextremelyshortrodshortsection.ThecenteringcylinderisahollowplastictubeinnerholeBixinshaftaround1MM,externalfourslightly***allerthanthediameterofthetubingcentralizerwing,adoptcasting.Thecentralizercanrevolvearoundtheaxistopreventthesuckerrodfromtouchingtheinnerwallwhenitrotates,anditcanalsoletthefluidpassthrough.)
