由煤炭部哈尔滨煤矿机械研究所负责研制的SP-1型喷头于1985年12月19日由煤炭科学研究院组织通过技术鉴定。专家们认为,“SP-1型喷头,经过地面和17个月的井下工业性试验证明,喷头降尘效果明显,回弹小,达到了部锚喷攻关的要求,具有国内先进水平。该喷头结构紧凑,主要参数选择合理,重量轻,性能稳定,操作,维修方便,可以定型,批量生产。”SP-1型喷头采用组合式的结构并逆向加水,各件均可拆卸,更换备件方便,结构紧凑,形式合理,重量轻,体积小,携带方便,能及时处理水环堵塞等事故,降尘效
By the Ministry of Coal Mine Machinery Research Institute of Harbin is responsible for the development of the SP-1-type nozzle on December 19, 1985 by the Coal Research Institute organized technical appraisal. Experts believe that “SP-1 nozzle, through the ground and 17 months of underground industrial tests proved that the nozzle dust effect is obvious, the rebound is small, has reached the requirements of the Ministry of anchor spray attack, with the advanced domestic level of the nozzle structure Compact, the main parameters of choice, light weight, stable performance, easy operation and maintenance, can be stereotyped, mass production. ”SP-1-type nozzle with a modular structure and the reverse water, all removable parts, spare parts to facilitate the structure Compact, reasonable form, light weight, small size, easy to carry, timely handling of water ring blockage and other accidents, dust reduction effect
