11、nk is increased. Through sealing oil filters through. Dont introduce2.1、减速器配件松动。加速器在组装时,合箱口、油封挡板螺栓紧固力矩达不够,螺栓松动造成漏油。2.1, reducer fittings is loose. Accelerator in the assembly, the close box mouth, oil seal baffle bolt tightening torque is not enough, bolt looseness caused the spill.2.2、减速机结构设计不合理引起漏

12、油,如设计的减速机没有通风罩,减速机无法实现均压,箱内压力升高造成漏油。2.2, the structure of the speed reducer design is not reasonable cause oil leakage, such as the design of the reducer without ventilation hood, pressure reducer can not be achieved, and pressure in the oil spill.2.3、重使用,轻保养,未按要求及时添加或更换润滑油。多数减速器自运行以来,一直没有更换润滑油,造成油料

13、乳化变质严重。2.3, heavy use, maintenance, not according to requirements in a timely manner to add or replace lubricating oil. Since most of the gear reducer running, there has been no oil change, caused by oil emulsification metamorphism.2.4、呼吸器堵,造成减速器内部压力升高造成漏油。2.4, respirator, reducer internal pressure

14、rise caused the spill.2.5、润滑油过多,润滑油飞溅严重造成漏油。2.5 too, lubricating oil, lubricating oil splash seriously cause oil leakage.2.6、合箱口密封不严。2.6 and box sealing mouth is lax.2.7、减速器回油槽堵。2.7 return chute blocking, reducer.2.8、油封失效或唇口磨损严重。2.8, oil seal failure or lip badly worn.3、渗漏的部位3, leakage parts在调查中,随机选

15、择76台在用游梁式抽油机进行研究,其中47台存在减速器漏油现象:其中中缝接合面漏油16台,轴承(包括输入轴、输出轴、中间轴)处渗漏20台,螺栓处漏油5台,放油孔、观察孔渗漏4台,其他部位漏油2台。In the survey, 76 sets of randomly selected in beam pumping unit is studied, including 47 units: speed reducer leakage phenomenon of raphe 16 sets of joint surface oil, bearing (including the input shaf

16、t and output shaft, intermediate shaft) leakage 20, bolt spill 5 units, 4 units, oil drain hole, observation hole leakage 2 other parts of the leak.4、渗漏原因分析4, analysis of the causes for the leakage4.1、中缝接合面渗漏的主要原因The main reason for the 4.1, raphe jointing surface leakage4.1.1、由于螺栓紧固程度差或由于振动造成松动,使合箱

17、口产生缝隙,使润滑油外溢。4.4.1, due to poor or degrees bolts loosening due to vibration, make the close box mouth produces aperture, make the oil spill.4.1.2、由于润滑油长期使用得不到及时更换脏或含杂质较多,堵塞了合箱口的回油孔道,回油不畅,使润滑油外溢。4.1.2, due to the lubricating oil use for a long time not change in time or with impurity more dirty, bloc

18、ked the mouth of the tanks on oil return hole, poor oil, lubricating oil spill.4.1.3、减速器组装时合箱口无垫片,未抹箱口密封胶。4.1.3, reducer assembly when the closed box without gaskets, didnt wipe mouth sealing glue.4.2、轴承处渗漏的主要原因4.2, bearings, the main reason for the leakage4.2.1、由于润滑油脏或杂质多,堵塞了轴承处回油孔道,使回油不畅。2, due to

19、 the lubricating oil dirty, or impurities, blocked the bearing return oil hole, make the oil return.4.2.2、由于长时间运转,使油封老化,磨损严重,甚至实效。4.2.2, due to the long time operation, make the oil seal aging and wear serious, even the actual effect.4.2.3、轴下沉,由于轴承齿轮使油封的密封效果受到影响。Holdings, shaft sinking, and due to b

20、earing gear oil seal sealing effect is affected.4.3、放油孔、观察孔处渗漏原因:4.3, set oil hole, observation hole leakage reasons:为防止盗油者从减速器放油丝堵和观察孔中放油,通常将丝堵与减速器本体焊在一起。由于丝堵未紧固好,或在焊接时将密封材料损坏,从而产生了渗漏。To prevent stolen oil is from the reducer oil drain plug and observation hole into the oil, usually will plug with

21、reducer frame welding. Due to good plug did not tighten, or when welding will be sealing material damage, causing the leakage.4.4、螺栓漏油的原因4.4 bolts, the cause of the leak螺栓处渗漏同缝接合面渗漏原因基本相同,只是润滑油由螺栓处渗漏出来,而未从接合面渗漏,或由于以前中缝处做过堵漏的部位,润滑油不能从原部位流出,而改由螺栓处渗漏。Bolt in seam with the faying surface leakage reasons

22、 are basically the same, just leakage of lubricating oil from the bolt, but not from the faying surface leakage, or due to the parts of raphe place do before plugging, oil cannot flow from the original parts, leakage by bolts.4.5、其他渗漏为减速器本身制造缺陷造成。4.5, other leakage for reducer itself due to a manufa

23、cturing defect.通过分析,减速器漏油的主要原因是:润滑油性能变差,加上杂质以及齿轮磨损的铁屑进入油中,使得润滑油变粘,润滑效果变差。飞溅润滑过程中,齿轮将含有杂质的润滑油带入减速器的润滑油道将油道堵塞,导致油从中缝或螺栓处渗漏;在轴承部位,刮油舌将含杂质的润滑油刮下,使杂质堆积在轴承附近,造成回油不畅,导致轴承部位漏油发生。Through analysis of speed reducer leakage is the main reason: lubricating oil performance becomes poor, together with impurities a

24、nd gear wear iron into oil, lubricating oil turned adhesive, lubrication effect becomes poor. Splash lubrication, gear will contain impurities lubricating oil into the gear reducer lubricating oil will oil road congestion, lead to oil leakage from the raphe or bolt; Will contain impurities in bearin

25、g parts, oil scraper tongue of lubricating oil, the impurity accumulation near the bearing, causing poor oil return, lead to bearing parts of the oil spill occurred.5、止漏技术方法5, check leakage technology method5.1、O型圈治理技术:用橡胶圈替换油封,一般能封堵10天至一个月。5.1, o-rings governance techniques: replace oil seal with r

26、ubber ring, generally can block 10 days to a month.5.2、油封换取技术:是对密封效果变差的油封进行更换,适用于三轴,该措施现场操作难度大。: 5.2, oil seal for technology is oil seal for replacement of sealing effect becomes poor, apply to the three axis, the site operation is difficult.5.3、胶封技术:用高性能弹性胶对接合面、机油观察孔、放油孔。5.3, glue sealing technolo
