针对煤矿井下现用的喷雾装置设备落后、使用寿命短、劳动强度大和雾化效果差的问题。龙王庄煤矿自主研发设计了风动高压喷雾泵,它具有结构简单、安全系数高、使用寿命长、雾化效果好、大大减小劳动强度等优点,在井巷喷涂作业中经过90 d的实验,效果良好,大大提高了喷涂质量和效率,为矿井喷涂作业带来了革命性的变化。 Aiming at the problem that the existing spray device in coal mine is outdated, the service life is short, the labor intensity is big and the atomization effect is poor. Longwangzhuang Coal Mine has independently developed and designed a pneumatic high-pressure spray pump which has the advantages of simple structure, high safety factor, long service life, good atomization effect and greatly reduced labor intensity. After 90 days of experiment in well lane spraying operation, , Good effect, greatly improving the quality and efficiency of spraying, mine operation has brought a revolutionary change.
