采油二厂基层采油作业区,油井生产过程中经常发生抽油机悬绳器挡板螺栓断裂,光杆脱离悬绳器现象,造成抽油机失载、杆泵脱离悬挂等一系列连锁破坏,影响油井正常生产。通过分析受力在不破坏原有受力结构的情况下,将悬绳器光杆挡板由压板式改为插板式,将单纯由螺栓受力变为由螺栓、插板和横担共同受力,使螺栓受力大为减小,从而解决了螺栓断裂的问题,同时也提高了油井生产效率,在现场试用后取得了良好的效果。 Oil production plant two grass-roots oil production area, the oil well production process often occurs pumping unit suspension rope baffle bolt breakage, the light pole off the suspension rope phenomenon, resulting in pumping unit load shedding, rod pump from the suspension and a series of chain damage, the impact Well normal production. By analyzing the force without undermining the original structure of the force under the circumstances, the suspension of the light bar baffle board by the plate type to plug-in, simply by the bolt force by the bolts, flapper and cross arm jointly stress , So that the bolt greatly reduced the force, thus solving the problem of bolt fracture, but also improve the production efficiency of the well, after the trial in the field and achieved good results.
