Research On The Metage System Of Pulverous Material

Save bank of straight form is an especial equipment, which is used widely in industry, but it happen accident easily. It has two big basic question, security of use and economy of inspect. In the near future, sonar technique is used widely in regular inspect of save bank of straight form. Comparing with other methods, for example, ultrasonic, radial and so on. Sonar technique has some merits, for example, dynamic character, holistic inspect, speediness, boon and so on. It not only assure the security of save bank of straight form, but also shortens the time of examine and repair and reduces the expenses of inspect. Save bank of straight form is affected by many bad facts and is damnified, because it works in natural environment and liquid level change condition . Especially medium leaks out then it will bring serious disaster ,environment of pollution and cause huge losing of national estate. Since 1990's, huge save bank increases continuance, its expenses of examination and repair, maintenance and alteration rise more. So it is useful to carry out security inspect and prediction, to assure run safely of save bank of straight form.The thesis aims at the actual instance of sonar inspect, which is use for save bank of straight form. It researches the rot and leakage of bank's motherboard, and carryout sonar inspect and prediction of save bank of straight form. Then it hopes to realize the dynamic inspect and scientific regulation of save bank of straight form.Caring out investigation of sonar inspect technique for save bank of straight form, the thesis develop analysis of sonar inspect datum which came from the leakage process of save bank of straight form, and adopts hydromechanical knowledge to research the mechanism and character which are brought by effective and active sound mine of bank's bottom. This thesis validated the feasibility, reliability as well as the change rule of sonar technique by researching in lab and simulating in locale. Carrying out research of sonar inspect technique, it research the change rule of sound mine in process of rotting, by analyzing the true datum of sonar inspect. These have the important meaning to instruct sonar inspect for bottom of save bank of straight form.The thesis advanced that adopting gray parallel connection analysis and statistic predicted the life of save bank of straight form by analyzing the laboratorial datum. It educed that the gray parallel connection analysis is better than the statistic finally by analyzing the result. According to the simulation in lab and sonar inspect for save bank of straight form in locale. It established the sonar inspect for save bank of straight form and whole evaluating means for the first time.
