我单位在安哥拉工程施工中所使用某些工程机械的三联泵因体积大、结构复杂、价格昂贵,且不属于易损件,所以未购置备品配件。在一次施工过程中,1台QY50型汽车起重机和1台D7型液压钻机发生了三联泵中某1个泵损坏的情况。经在当地询问没有此种配件,而订货的供货期在20天以上,且只供应总成件。为了不延误施工工期,我们决定尝试将这2台设备三联泵改为双联泵。
My unit in the Angola construction project using some of the construction machinery triple pump because of its large size, complex structure, expensive, and does not belong to wearing parts, so did not purchase spare parts. During one construction, one QY50 truck crane and one D7 hydraulic rig suffered damage to one pump in the triple pump. After the local inquiry no such accessories, and orders for more than 20 days, and only the assembly parts. In order not to delay the construction period, we decided to try these two devices triple pump to double pump.
