我厂使用的Q3113A抛丸清理滚筒,其液压系统的λ1φ-18叶片泵(流量18L/min,压力6.5MPa)属淘汰产品,目前市场上不易买到,维修比较困难。今年我厂使用的λ1φ-18叶片泵转子断裂,抛丸清理滚筒无法使用。我厂选用了3YB_1-16叶片泵(流量16L/min,压力6.3MPa)代替。根据YB_1-16叶片泵的情况,在安装过程中稍作一些改进:(1)将吸油管与泵连接部分改为ZG1＂锥管螺纹,如图1所示。利用原吸油管,则把KG3/4＂去掉
The Q3113A shot blasting cleaning drum that our factory uses, its hydraulic system λ1φ-18 vane pump (flow 18L / min, pressure 6.5MPa) is to eliminate the products, the market is not easy to buy, maintenance is more difficult. This year I plant the use of λ1φ-18 vane pump rotor break, shot blasting cylinder can not be used. I plant used 3YB_1-16 vane pump (flow 16L / min, pressure 6.3MPa) instead. According to the situation of YB_1-16 vane pump, some slight improvements are made in the installation process: (1) Change the connecting part of oil suction pipe and pump into ZG1 “taper pipe thread, as shown in Figure 1. Using the original suction pipe, put KG3 / 4 ”removed
