6m shaft steel tank equipped with beam spacing of research
This, 6rn spacing wells simple equipment reliability,mbt shoes ireland (http://www.mbtshoesireland.org), including reliability,ghd planchas (http://www.ghdplanchases.net), strength, reliability, rigidity, fatigue reliability and power stability and reliability of a number of indicators to reliability index 'K said: Ki = f (,tory burch outlet (http://www.toryburchoutletonline.org), Kc,tory burch outlet (http://www.toryburchoutletshop.org), △,) Type in the piece goods - equipment, shaft strength reliability; - well simple and equipment reliability, rigidity; such as - fatigue shaft equipment reliability; - shaft equipped with power, stability and reliability. If Ki> 1,6 m spacing wells equipped with simple and reliable; Ki <l, 6m spacing shaft equipment used is not reliable. '2 .2 Factors affecting reliability and improve the reliability of the measures affect 6I'll spacing reliability factors, including: improved parameters, shaft cross-section form and combinations of equipment, abrasive speed and shaft cross-section cross-section layout. (1) enhance the argument. Improved parameters (increase speed, improve end-load) determines the level of the peak load force size and the size of K. Studies have shown that the level of force to enhance the speed of the peak load is greater than the degree of influence to enhance the terminal load. Therefore, to enhance the capacity to ensure the premise of mine, reducing the level to enhance the speed and effectively reduce the peak power load, reducing the impact of the role of frequency of horizontal force, thereby enhancing the 6m spacing wells simple equipment reliability. (2) Wells Jane section of the form and combinations of equipment. Shaft equipment, the greater section modulus, the stress and the effectiveness of such magnitude smaller, the greater moment of inertia, the greater rigidity,, △, and is also greater. So 6m spacing units should be used in wells equipped with simple, light weight, section modulus and moment of inertia are large combined beam-section cans, cans Road. China's current equipment commonly used in combined-type shaft section with welded steel bar and the overall system of two kinds. Tie together the overall system performance-section is much larger than the soldering section of fatigue, according to calculations, the overall fatigue strength of rolled section is welded section 1.5. Equivalent stress amplitude in the same case, the overall cross-section rolled well simple and equipment reliability index is 1.5 times the welding section. Therefore, 6m spacing unit shaft equipment should be used in lightweight, cross-section modulus of the overall system of co-rolled sections, such as hot-rolled hollow square steel. (3) the speed and mode of life. Jane equipment work well in abrasive conditions, the corrosion situation is good or bad for the 6m spacing shaft equipment reliability and life has a direct impact. Well equipped with simple cross-section erosion rate (mm / a) as a measure of its antiseptic quality indicators. Preservation is good: 0mm / a; corrosion better = 0.10.2rrmr / a; corrosion generally = 0.2-0.4mm / a. Well simple high level of equipment corrosion, abrasion rate of small cross-section, its long life, high reliability. Well with the simple life of equipment to increase fatigue strength and reduce its cross-section mill with the amount of life increases, so well with the simple life of equipment reliability, increased gradually reduced. 6m spacing to enhance well equipped, especially Jane corrosion bunton work is to improve the reliability and effective measures to prolong its life. (4) cross-section layout. Well equipped with simple cross-section layout is different structure from the vibration frequency is not the same, the same cross-section layout is fixed with subsidiary structures, the frequency difference is also significant. Section layout properly, Kr = 1 时 enhance container run dynamic instability may occur. By optimizing the wellbore cross-section layout, simple equipment to reduce the well adjunct can improve its structure from the vibration frequency, spacing of wells to improve 6nl layer stability and reliability of simple power equipment. 3 Conclusions (1) 6m and 4m beam spacing shaft tank equipped with the same or similar load characteristics, structural characteristics and failure mode, 6m beam level can ask the horizontal force from the shaft equipped with the peak load reductions, and the level of force to reduce the impact of the role of frequency , well carrying capacity of simple equipment, has also been reduced. (2) 6 cans of beam spacing shaft equipment reliability, including reliability, strength, reliability, rigidity, fatigue, reliability, and reliability of dynamic instability. The main factors affect the reliability of the upgrade parameters, shaft equipment, forms and combinations of cross-section, cross section and the useful life of abrasive speed and shaft cross-section layout. (3) improve the 6m beam spacing wells simple tank and equipment to optimize the reliability of the measures taken to enhance the parameters to reduce the speed upgrade, the choice of unit weight, section modulus, the overall round-section tanks rolled beam and bunton enhance wellbore equipment corrosion work to optimize wellbore cross-section layout.
