摘要
介绍了BWZ－250型水泵泡沫增压器的结构、工作原理，最大增压值5．0MPa，排量可满足要求，容积效率达0．9。用低压空压机配合增压器．进行泡沫钻进，合理又经济，经在3个矿区使用，取得了较好的效果。
The structure and working principle of BWZ-250 pump foam booster are described and it can provide a pressure increase of 5. 0 MPa with satisfactory pump rate and volumeric efficiency upto 0. 9. It is reasonable and economical to carry out foam drilling with low pressure compressor. Good results have beenachieved in three mines.
