Deepwater Horizon explosion and oil spillMain article: Deepwater Horizon oil spillOn April 21, 2010, the Deepwater Horizon oil platform, located in the Mississippi Canyon about 40 miles off the Louisiana coast, suffered a catastrophic explosion; it sank a day-and-a-half later.[14] Although initial reports indicated that relatively little oil had leaked, by April 24, it was discovered that approximately 1,000 barrels (42,000 gallons) of oil per day were issuing from the wellhead, about a mile below the surface on the ocean floor.[15] On April 29, the U.S. government revealed that approximately 5,000 barrels of oil per day (210,000 gallons), five times the original estimate, were pouring into the Gulf from the wellhead.[16] The resulting oil slick quickly expanded to cover hundreds of square miles of ocean surface, posing a serious threat to marine life and adjacent coastal wetlands, and to the livelihoods of Gulf Coast shrimpers and fishermen.[17] Coast Guard Rear Adm. Sally Brice O’Hare stated that the U.S. government will be “employing booms, skimmers, chemical dispersants and controlled burns” to combat the oil spill. As of May 1, 2010, the oil spill cleanup efforts are underway, but hampered by rough seas and the "tea like" consistency of the oil. As of May 27, 2010, USGS had revised the estimate of the leak from 5,000 barrels a day to 12,000-19,000 barrels a day.[18]
主要看发动机如何漏油,如果是轻微的渗油的话,更换一下密封圈或者密封垫就可以了。如果是漏油多的话就要重视了,建议去维修站进行检修。机油一旦减少,发动机内部温度就会高,发动机就会零件就会磨损,最终会导致发动机拉缸,发动机就基本报废。
或要花钱大修了。如果是轻微渗油,或其中包含油气的话,不会对发动机有太大的影响。建议可以继续使用观察一下。渗漏油、阴漏油只要看在哪个部位就怀疑哪个部位,一般是在接缝处最多。
有的只要自己动手紧一下相关的螺丝就行。发动机漏油的常见原因:1、油底壳衬垫损坏或螺丝松动漏油;油底壳放油螺塞衬垫损坏、松动漏油。2、发动机支架板变形或衬垫密封不严漏油。3、气门室盖衬垫密封不严漏油。
4、曲轴前、后油封损坏漏油;凸轮轴承后封盖不严漏油。5、涡轮增压漏机油。6、机油散热器密封不严漏油。机油,即发动机润滑油,被誉为汽车的“血液”,能对发动机起到润滑、清洁、冷却、密封、减磨、防锈、防蚀等作用。
发动机是汽车的心脏,发动机内有许多相互摩擦运动的金属表面,这些部件运动速度快、环境差,工作温度可达400°C至600°C。在这样恶劣的工况下面,只有合格的润滑油才可降低发动机零件的磨损,延长使用寿命。
机油,即发动机润滑油 英文名称:Engine oil。密度约为0.91×10?(kg/m?)能对发动机起到润滑减磨、冷却降温、密封防漏、防锈防蚀、减震缓冲等作用。市场上的机油因其基础油不同可简分为矿物油及合成油两种(植物油因产量稀少故不计)。
合成油中又分为:全合成及半合成。全合成机油是最高等级的。机油由基础油和添加剂两部分组成。基础油是润滑油的主要成分,决定着润滑油的基本性质,添加剂则可弥补和改善基础油性能方面的不足,赋予某些新的性能,是润滑油的重要组成部分。

(4) Should check the work condition of the row spirit valve slice in time when pump appeared excrescent row spirit voice and oil noodles motion.
The Deepwater Horizon, owned by Transocean and leased to BP, caught fire April 20 after an explosion and sank. Eleven oil rig workers are missing and presumed dead. The rig, with a platform bigger than a football field and insured for $560 million, was one of the most modern and was drilling in 5,000 feet of water. Remotely operated vehicles located two places where oil was leaking from the well pipe, the U.S. Coast Guard said. The Coast Guard said there was an area 42 miles by 80 miles with a rainbow sheen of emulsified crude located less than 40 miles offshore. An oil rig 10 miles away from the Deepwater Horizon was evacuated as a precaution. Environmentalists noted that although the sunken rig's distance from shore gives oil companies more time to keep the spill from reaching U.S. coastlines, it also means that the water is deeper, making it harder to get the spill under control. "It's good because it gives you the chance to intercept it before it reaches the coast, but it is harder to cap a well the deeper the water you're drilling in," said Aitan Manuel, an expert on offshore drilling at the Sierra Club. "It's presenting a lot of challenges to the companies." 不好意思啊,我只能写这么多...我不光翻译了,还从报纸上抄了几句话...话说最近加拿大的报纸上天天都报道这事...闹得够沸沸扬扬的啊...够美国人郁闷的了...
Ⅳ ,gearing explain1,pump proper gearing in the aridity, well ventilated, sweep of situation; 2,the pump use a piece of scaleboard with the electrical engineering, the scaleboard and ground connect to touch.The ground should be solid flatness, the pump put should steady really.Chase a pump with a ground of feet stud bolt fixed in ground, pump on all sides should stay to dismantle to pack to maintain space just the right amount. 3,pump and is take out the container conjunction and can use soft tube or metals hard tube, use metals hard take care of, can on the piping the additional rubber take care of, the metals ripples tube or inside shoot a soft tube of the plastics of the spring coil a transition to reduce vibration and improve to deal with contact to seal completely; 4,the electric motor change direction and should revolve a direction up with pump consistently, disallowing inversion.According to electrical engineering mark the card provision link power supply, ground line and very the capacity fuse wait to protect the electrical engineering safety of measure. 5,the pump enter the windpipe way to press the vacuum system a widespread principle, should be as far as possible big, as far as possible short, the light that is as far as possible, as far as possible clean, as far as possible little curved head, is take out with decrease to lose soon. 6,for avoid stop pump pump to return inside the oil into is take out container, proper Be pumping to install vacuum to close the valve and 充 to annoy valve.Currently the simple method is pumping to install to correspond a set of the specification electromagnetism vacuum to take the 充 spirit valve(DDC-JQXX) then, this valve open,the pass and pump open, stop synchronously carry on. Ⅴ ,Usage1,break a continuous start pump(number of times not proper excessive), observe the pump oil noodles to be placed in the oil mark Central Cross-Island highway line to attach closer, then can throw in a normal operation;The oil noodles lead low, can stop a pump to encourage to the oil mark center horizontal line, if the oil noodles lead high, then need to stop pump to put oil to the oil mark center horizontal line a neighborhood, otherwise will have already shown 著 to spray oil; 2,be the environment temperature low pump in 5 ℃s but hard start, can let out oil to heat to 20-30 ℃s to join a pump again, then then the start pump, or place with the electric stove in the pump to heat side. 3,be to take out in addition to take can the air of the 凝 steam, can open spirit the town valve to revolve a 30-60 mins to even grow a little time more, for the convenience of in can the 凝 air expel, prolonging the service life of the pump oil; 4,allow a pump WEN ≤ (the oil temperature-environment temperature)=40 ℃s, be more than 40 ℃s, need to strengthen airiness to spread heat to the pump; 5,enter the air temperature degree and should control to be no higher than 40 ℃s. 6,stop the empress of the pump and must close valve in the spirit town, in order to prevent leak oil. Ⅵ ,Maintenance with maintain1,usually notice the oil while revolving normally the oil noodles be placed in the oil mark center horizontal line neighborhood, didn't want high also however low;While noticing the quality variety condition of the oil in the meantime, being the oil obvious scension or the oil color to present a white(Huang) form of milk, the elucidation pump inside enter the water or other materials, need the check exclusion. 2,change oil term:Pump a suggestion generally and lately Be revolving over 100 hours or so change once, so a,two times after the square can lengthen to change the oil term, such as if is take out container inside what to draw out is dry sweep of air, suggest can change oil once in 500-1000 hours; If when the air been draw out has the causticity or meeting and the pump oil since the chemical reaction, in order to don't influence a vacuum, then in addition to carrying on before the air enter pump to handle first, can also use frequently a way of change the oil to make up. Could not reach an index sign value of factory famous brand towards depositting the pump that the term grow the extreme limit pressure usually, at this time can the closeness pump open valve in the spirit town to gasp 4 small enter or so then;Can change oil when it's necessary; Change an oil method:The closeness enters spirit, openning to pump 0.5 hours, again from put the oil bore to put oil, then entered the spirit in the atmosphere pressed down to gasp a 0.5 mins, in the meantime from entered the spirit slowness to join jot to sweep the vacuum pump oil, in order to the displacement pumped the memory oil, and keep lubrication, after it let out after 旋 put the oil 螺 to fill tightly, from encourage bore to join new oil, notice not let the grain miscellaneous articles or objects sneak into oil. Pump oil to adopt the SY No.1634-701 vacuum pump oil generally. 3.the pump should order to make the system that the different periodical check fix according to the different usage condition.Principle BE: (1)Under general circumstance take out in addition to of the air is dry and clean, the suggestion can check to fix after pumping to use for 2000 hours. (2)New pump devotion operation full 500 carry on a check to fix towards lining up spirit valve after hour, hereafter can consider the feeling extension or shorten check to fix period.
