A grease, eyebrows tiny cu, eyes after lens, always thoughtful. Workers daily reporters saw Li Yongxiang one day, he led the team at the scene of the maintenance. "Two days later must ensure that the device drive!" As the jilin petrochemical company in eastern inspection maintenance built a shop fitter monitor, Li Yongxiang often want to race with time - a day earlier fixed equipment failure, let the machine a day earlier, enterprise less loss in a day. As emergency doctors and killing emergency race, this kind of contest, needs to consummate medical skill, also need a high degree of professionalism. Connecting device for 24 hours of continuous operation of petrochemical plants is the "heart", its healthy or not directly related to the production can proceed smoothly. Over the years, Li Yongxiang not only with his "listening, asking and" contortionists "cures" nearly ten thousand units (sets) of fault machine, also with a superior technology, completed the localization of key components imported equipment more than 30 items. "Skilled maintenance, as the good medicine" on July 23, on Saturday, at 4 PM, Li Yongxiang scene maintenance, jilin petrochemical refinery heavy rush suddenly connect three telephones: "hydrocracking workshop C1101 circulating hydrogen compressor fault, device was forced to stop all!" Li Yongxiang to fault the scene immediately "listening, ask," judge for less than two minutes: dry gas seal failure! To disassemble the device, usually it takes at least nine hours, Li Yongxiang but it only took 4 hours. Overhauling the results showed that his diagnosis not bad. We all breathe a sigh of relief: just change the seal! Li Yongxiang said: "dry gas seal normal life for 3 years, why the seal failure? Only 13 months must find deeper causes! Otherwise, change the new seal, also afraid of taking difficult long!" Between the two a day later, Li Yongxiang only slept for three hours, finally find out the fault causes, successfully complete all "surgery". This is an emergency call, in Li Yongxiang is the norm, regardless of holidays. "Skilled maintenance, as the good medicine", Li Yongxiang are accustomed to. Since he graduated in 1998 in jilin petrochemical, 18 years, he has wonderful hand "cures" connecting equipment near ten thousand units (sets). Attack a problem ", is a happy harvest "of the high price of imported equipment, once the" du xuan ", not just headache, more love dearly. In July, 2009, 4 million yuan worth of refinery 2 american-made CFR octane rating testing machine appear problem, testing data is not accurate, ultra error 3 units, make the enterprise loss of at least 2 million yuan every day. Outside experts team, please repair, costs 100000 yuan/services cancelled, fixed, however, less than a week, testing machine and so the disease relapse, factory leadership is very worried. This machine is the most authoritative international determines the size of the gasoline octane number on equipment, maintenance technology involving mechanical, electrical, instrumentation, blending, and other fields. Li Yongxiang unafraid to challenge, grasped the nettle. More than 200 pages of equipment specifications, he looked again at, search for related papers, then the precision instruments and bold "mutilated", hundreds of parts given, totally conquer 2-seeded 8 days slips "data" and other ills, until now, they has also been health work. "As stipulated in the factory, this 2 instrument maintenance once a year. That is to say, Li Yongxiang not only avoided huge losses for the enterprise, but also can save 200000 yuan each year of outsourced maintenance costs." Workshop director told reporters. Li Yongxiang there are many small notebook, as always, to the full of technical problems. On July 17, 2010, he used a red pen to write down these words: "the device does not turn, expensive and iron again." At that time, the company has a set of imported compressor fault since "duty" have been continuously, can only be set aside. He time Li Yongxiang crouched beside the unit overhaul, measurement, calculation... At last, he found nine points, again after 1 months for the equipment operation "gut", finally make it back from the dead. Attack a problem ", is a happy harvest." Entry to date, Li Yongxiang has done 100 technology innovation, equipment problems in more than 500, with nearly half is the result of regulation "the equipment". "Xiang zi", "contradiction" in the unit, Li Yongxiang has two, one is "xiang", homophonic Lao she's camel xiangzi, referring to his clinging dedicated, diligent, hard-working; Is a "contradiction", referring to his superior technology, strives for perfection, delights in solving production contradictions is sunup "contradiction" spirit in contemporary outstanding representatives. Li Yongxiang willing to accept the two address. In his eyes, this is a qualified "craftsmen" should have the basic qualities. "The promotion enterprise's product quality, the transformation of made in China to created in China, can't do without a large number of highly qualified workers." He said. In line with a craftsman our, in August, Li Yongxiang after repeated research and experimentation, 2 months to 2 imported reciprocating compressor "transplant" him "localization" organ of independent research and development. So far, he has to complete the localization of key components imported equipment more than 30 items. One estimate, Li Yongxiang cumulative section and benefit for the enterprise in ten million yuan of above, but it seems to his disciples, teacher cannot measure of great value, also is passing down the spirit more young mechanic. "Said 'keep improving it. After 90 qinggong Cao Kuan told reporters, "a few days ago we repair a pressure machine, the key points, is in a steam turbine and compressor shaft alignment. In general, the precision error less than 0.06 mm. May further master request to reduce the error, take us dry until 1 a.m, error control in 0.02 mm." "Error is smaller, the more stable plant operation; the smaller the error, the more you have to." Under the precept of Li Yongxiang without reserve, its door disciple every last year won the seventh session of the national petroleum and chemical industry vocational skills competition gold medal, Cao Kuan will also be the gold medal in her arms. Also in 2015, 37, Li Yongxiang glory were appraised as the national model worker.
