分析了传统的矿用乳化液浓度配比装置的工作原理及存在的配比精度和成本的问题,介绍了一种不需要进行防爆设计的往复式单柱塞配比装置的设计.该装置根据固定的面积比进行乳化液浓度配比,使乳化液浓度不受供水压力等外界参数变化的影响,配比精度高；该装置不需要额外的液压泵和马达,生产成本较小,并且属于纯液压式装置,不需要防爆设计.试验结果表明,该装置运行稳定,各项指标达到了设计要求.%The paper analyzed working principle of traditional mine-used blending devices of emulsion concentration and theirs problems of blending precision and costs, and introduced design of a reciprocate type blending device with single-piston which does not need explosion-proof design. The device makes emulsion concentration blending according to fixed area ratio which can make emulsion concentration be not influenced by change of water pressure and other external parameters, and it has high blending precision. The device does not need extra hydraulic pump and motor with low production costs, and it belongs to pure hydraulic device, so it does not need explosion-proof design. The test result showed that the device runs stably and each index reaches design requirements.
