Major mechanical equipment, failure analysis and prevention
} The first two furnaces fire arm accidents caused by fire incidents were not bursting to identify or find the real cause of failure of furnace operation. Through the failure analysis and safety assessment, has been in the safe operation of more than 6 years, without any burst failure phenomenon, to ensure the chemical raw materials ~ - alkyl safe production, and significantly enhanced the broad economic benefits. Increase in machinery and equipment accidents 3.2t husband maple major equipment such as power generation sets of machine equipment, chemical equipment and large-scale means of transport, accident rates have increased the pressure only for the cake pit devices, according to incomplete statistics, China's million boilers, pressure average burst the container is the world's developed countries, more than l0 times, major accident is the world's developed countries, 10o times. Faced with a serious situation than that, treatment and prevention of accidents has come to a time delay. If petrochemical furnace for the side, China's petrochemical industry in the sixties and seventies of the industrial furnace put into operation more than 80 of the total, have been used into the late, more serious purpose of aging equipment,ugg prezzo, especially the furnace tube, Creep control considerations,ugg milano, has come to replace the stage playing. Especially the new high-pressure, high temperature and high degree of automation machinery and equipment soared, including the introduction of advanced equipment from abroad, as technology can not keep up, the operator of total posts poor technical quality and other factors also contributed to the increase in accidents One of the reasons. Another example is the introduction in recent years, large-scale generating units 600MW boiler economizer in the superheater,air jordan shoes cheap, reheater and water wall so the management, installation, improper operation of the furnace and other causes cracking and failure of ejaculation frequency increased over time Sudden increase of 33 more things open many major accidents have a lot of machinery and equipment is sudden, before the accident have any signs of vote after the accident cause greater 』, member of casualties and huge economic losses after the accident Failure analysis requires workers to find out as soon as possible the real cause of failure, and propose effective improvements such as Shanghai Petrochemical Plant hydrocracking unit of hydrogen and oxygen tube furnace accident, is a typical sudden accident, stove pipe. 15 × 1OP8 pressure of oxygen-millimeter-long cracks in the hundreds of smoke, a large number of combustible gases in the combustion furnace and burning the small number and then stove pipes and chimneys. The economic losses it causes loss of the country tens of millions of dollars before taxes, discontinued the day will reduce the 400 million value of the national income. When we receive this task, rushed to the site testing and sampling, hard for three days and three nights to find out the reasons for the furnace tube. Timely repair, saddle quickly resumed production, the completion of the task Paul pestle. Another example of a description of the sub-sea city of Bridge Approach device is a typical accident broken sudden accident, the accident occurred when there are no signs of Sa 【II, the accident resulted in many casualties. 4 years of doing a good job failure prevention, failure analysis has made great achievements, to improve the quality and extend the service life of machinery and equipment to make great contributions to the small failure analysis on the current situation, but look, there are still no further problems, especially failure prediction and prevention is carried out is relatively small, compared with the industrialized countries there is a big gap between midship and does not meet the current situation of reform and opening up, which should attract enough attention. 4.1t Li failure prediction and prevention of the specialized agencies of the world's industrial countries,ed hardy clothing, are equipped with accident investigation, accident analysis, failure prediction and prevention,air jordans, and safety assessment of an independent body, these institutions ensure the security barrier Mount machinery and equipment production and industrial development play Ding an important role in a variety of reasons, our country has not yet been established with the objective of these meet the requirements of specialized agencies. Temporary deployment of staff over the years has always taken the way organizations carry out accident investigation, accident analysis and prevention of hard testing, the results are often different opinions on failure analysis personnel, difficult to draw objective, and impartial scientific conclusions. As for the vicious things put some major, very complex reasons involved, the provisional institutions more balance at the end can not be resolved in the short term. Often a short term, the top test reach the top and accident prevention purposes, and no fundamental solution to the long-term safe operation of machinery and equipment issues. Not only to establish a specialized agency of the national and local level j pi to establish a special agency under the unified leadership at the national level agencies to carry out analytical studies, Limbo sound barrier with the construction of a series of failure analysis and prevention of a set of laws 々 and regulations. 4.2 to promote the application of new technologies and the large-scale power generation equipment, petroleum chemical industry equipment is a continuous large-scale production, shutdown day will result in hundreds of million of economic losses. Industrial countries have been capable of doing a three-year overhaul of machinery and equipment, while still in the country most of the scattered reason the University once a year, there are management problems, has a staff of pro-quality issues, as well as the application of new technologies such as large Q shrews chemical equipment by the environment or serious corrosion of crude oil (continued on page 42 J
