我处1986年从日本新泻铁工所进口了一台 NP800PT 型沥青砼拌合机.在使用中出现了一些故障,我们进行了部分改型与修复,至今使用效果较好,取得了一定的经济效益,现将改进修复方法简单介绍如下,供同行们参考:1 矿粉输送不利该机设计产量为48～64t/h.但由于该机矿粉贮存仓角度设计不合理使得矿粉输送不畅,经常需人工振捣,且每盘矿粉计量时间长达60～70s,造成每盘料都等矿粉,最高产量仅42.1t/h;在操纵室无法控制矿粉输送.我们对其进行改进修复.方法是:1.1 在不改变原矿粉输送机构传动比的前提下,将原矿粉计量输送电机由0.75kW 改换为1.5kW;1.2 将主动链轮直径由73mm 改为146mm;链轮齿数比由13:26改为25:26;1.3 在贮存矿粉仓壁上加装一只小型矿粉振动器,同时增设控制室电器线路,在控制
We imported an NP800PT asphalt concrete mixer from Japan’s Niigata Iron Works in 1986. Some faults occurred during the operation, and we made some modifications and repairs, so far, it has been used well and achieved a certain Economic benefits, the repair method will now improve a brief introduction is as follows, for colleagues reference: a negative impact on the delivery of the machine design output of the machine is 48 ~ 64t / h.But due to the design of the machine slag storage angle is not reasonable so that the transport of mineral powder is not Chang, often need to be manually vibrated, and the measurement time for each plate of ore powder up to 60 ~ 70s, resulting in each ore are equal powder, the maximum output of only 42.1t / h; uncontrolled in the control room slag transport. The method is: 1.1 without changing the transmission ratio of the raw ore powder delivery under the premise of the raw ore powder metering conveyor motor from 0.75kW to 1.5kW; 1.2 the diameter of the drive sprocket from 73mm to 146mm; sprocket number of teeth Than from 13:26 to 25:26; 1.3 in the storage of mineral powder warehouse wall to install a small mineral vibrator, while the addition of control room electrical wiring in the control
