    首頁:新聞技術 >> 托輥的發展及存在的問題

    中國改革開放以來,國民經濟高速發展,散料運輸業出現了前所未有的增長,帶式輸送機已經逐步成為散料運輸的主要手段。在煤礦井下運輸巷道,帶式輸送機由過去的100-630T/h運輸量、1.6-2m/S帶速,向1500—7000T/h運輸量、3.15-5.3m/S帶速以上發展。帶式輸送機正朝著大型化復雜化方向發展,目前,最大裝機功率達到25000kw,系統最長輸送距離145km,單機最長輸送距離20.3km,最大輸送量20000t/h,最大帶寬2800mm,最大帶強ST7000,最大帶速8.5m/s。 Since China's reform and opening up, the national economy has been developing at a high speed and the bulk transportation industry has experienced unprecedented growth. The belt conveyor has gradually become the main means of dispersance transportation. In the mine underground conveyance, belt conveyor is developed from the past 100-630t/h transport, 1.6-2m/S speed, to 1500-7000t/h transport, 3.15-5.3 m/S. Belt conveyor is developing in the direction of large-scale complex, at present, the largest installed power of 25000 kw, the system maximum transmission distance of 145 km, the longest single transmission distance of 20.3 km, the maximum throughput of 20000 t/h, maximum bandwidth 2800 mm, with strong ST7000, biggest biggest tape speed 8.5 m/s. 帶式輸送機的主要部件配套能力已經形成,如高壓大型電機、軟啟動技術、大型減速機、制動器、高強度膠帶等,唯有高速大承載托輥的技術指標滯后,不能很好地滿足要求。 A major part of the belt conveyor supporting ability has been formed, such as high pressure, large motor soft start technology, large-scale reducer, brake, high-strength tape, etc., only has the high speed bearing roller of big technical indicators lag, not well meet the requirements. 托輥是帶式輸送機上承載載荷的部件,數量較多,它的質量好壞,影響到帶式輸送機的整體參數和質量。按當前的設計配置,托輥在帶式輸送機中占到總價的1/5---1/4,在深槽、高速、大運量、長距離帶式輸送機上,將近占到1/3,托輥是個消耗品,它的耗損值,居帶式輸送機運行成本的首位。 The roller is the load bearing part of belt conveyor, the quantity is more, its quality is good or bad, affecting the integral parameter and the quality of belt conveyor. According to the design of the current configuration, in belt conveyor roller make up about a quarter to 1/5 of the total value of the -- -, in deep groove, high speed, large capacity, long distance belt conveyor, account for nearly one-third, roller is a consumable, its loss value, the belt conveyor running cost first.
