| 一、 applications
the series BQW, YBQW are produced by standard Q/S 02 001-2005 and Q/SB 02 002-2005 and as well as the related mining standards. It is mainly used to transport coal slime with suspended coal power. Used in flows: 20-600m3/6; lift: 15-700m. They can be used vertical, inclined, and even horizontal. They are equipped with constant-voltage governor specially intended for underpit sewage, and able enough to thoroughly remove water. They feature scientific structure, energy saving, easy installment and maintenance, and stable functions.
