The solution: find the plunger adjustable arm or gear from the speed control rod protruding ears slot prolapse, should re-open the fuel pump is installed correctly; also check whether the cross-slot wear and tear is too large, if found dead in parked for seca column position, should be demolition of repair or replacement parts; injector should be able to check the plunger is serious wear and tear, deputy returned to the oil valve gasket is worn; demolition injector, check whether the coupling of needle stuck in the closed position, needle and the injection hole Does burning, according to test results even to repair or replace parts.

解决办法：发现柱塞调节臂或齿轮凸耳从调速拉杆槽中脱出，应拆开喷油泵重新正确安装；同时检查叉槽是否磨损过大，如发现柱塞卡死在停供位置，应拆卸进行修复或换新件；喷油无力应检查柱塞副是否严重磨损，回油阀垫圈是否磨损；拆卸喷油器，检查针阀偶件是否卡死在关闭位置，针阀与喷油孔是否烧损，根据检查结果进行修复或更换偶件。

Injector fuel supply or pressure is not enough, atomization bad, drip, etc.; plunger rod adjustable arm or teeth protruding ears from the governor lever fork slot prolapse in non-oil position; fuel pump plunger and barrel assembly seriously wear and tear, oil pressure is too low, the oil valve wear serious Mifengbuyan; washer crack and deformation, a broken valve spring, injector wear and tear stuck in the closed position.

喷油器不供油或压力不足、雾化不良、滴油等；柱塞调节臂或齿杆凸耳从调速杠杆叉槽中脱出处于不供油位置；喷油泵柱塞偶件严重磨损，供油压力太低，出油阀磨损严重，密封不严；垫圈开裂变形，出油阀弹簧折断，喷油器磨损卡死在关闭位置。

Based on the practice of the use of φ95mm subsurface sucker rod pump in Shengtuo Oilfield in recent years, the causes of the failure of the pump are analyzed, and relevant precautions are put forward:(1)selecting oil wells with sufficient fluid supply for pumping;(2)under the condition of the pump efficiency being the same, the submergence depth of the pump being somewhat larger than that of the small pump, and 450～500m being feasible;(3)adopting Grade H ultrahigh-strength rod string and fixing a sinker bar at the bottom of the rod string;(4)selecting long stroke and low pumping speed, and more than 5m stroke and less than 6min-1 pumping speed being recommended;(5)adopting zirconium oxide valve ball and seat ＋ spray welded plunger ＋ nitrided barrel.

根据胜坨油田近几年采用φ95mm有杆抽油泵提液的实践，分析了造成这种抽油泵失效的原因，包括与其配套的脱节器失效、抽油杆断脱、泵漏、电动机不配套和生产管理不善等。为增强泵的提液能力和工作可靠性，提出5 项预防措施：(1)选择有充足供液能力的油井；(2)在保持相同泵效的情况下，泵的沉没度应略大于小泵，推荐按450～500m设计；(3)采用H级超高强度抽油杆柱，并在杆柱底部配置一定重量的加重杆；(4)采用长冲程、低冲次的参数匹配，推荐光杆冲程大于5m，冲次小于6min-1；(5)为提高泵筒、活塞和阀座的防腐耐磨性，推荐采用&氧化锆阀球和阀座+喷焊柱塞+氮化泵筒&的结构形式。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
