目前,我国的石材工业虽有欣欣向荣,发展较快之势,但由于基础薄弱,配套工业跟不上,仍处于设备陈旧、技术落后、产量低、质量差(特别是荒料质量)、能耗高的状态。因此,通过技术改造和设备更新,抓好石材工业的节能工作,应当切实引起重视。下面仅就比较普遍的、五十年代水平的螺杆锯石机及其配套设备的设计数据进行分析: 一、旧式螺杆锯机,主机动力为17千瓦调速动力为1.1千瓦进尺动力为3千瓦。二、配套手扶研磨机4台,每台设计动力为3千瓦。三、配套手摇切边机1台,设计动力为7.5千瓦。以上这样配套进行生产的石材加工厂,为数不少,颇有代表性。若按其总设计动力的15%计算其辅助动力,那么该配套设备的总动力为46.69千瓦。按一年300个工作日,日开三班计,工作时
At present, although China’s stone industry flourishes and develops rapidly, due to its weak foundation and unmatched supporting industries, it is still in obsolete equipment, lagging technology, low output, poor quality (especially raw material quality), and energy consumption. High state. Therefore, through technological transformation and equipment renewal, and grasping the energy-saving work of the stone industry, we should earnestly pay attention to it. The following is only a comparative analysis of the design data of the more common screw sawing machines and their supporting equipment in the fifties. First, the old-fashioned screw saws, the main engine power is 17 kilowatts, and the power is 1.1 kilowatts. The power is 3 kilowatts. Second, supporting four handheld grinding machine, each design power is 3 kilowatts. Third, matching hand-cutting machine 1, design power is 7.5 kilowatts. There are quite a few representative stone processing plants that support such production. If the auxiliary power is calculated at 15% of its total design power, the total power of the auxiliary equipment is 46.69 kilowatts. According to 300 working days a year, three flights a day, when working
