QYF20-30 mine pneumatic dredging sewage pumps, QYF mine clearance pneumatic pump sewage sludge, QYF20 / 30 pneumatic sewage pumps, pneumatic pumps clear silt, QYF17-20, QYF25-19, QYF10-20 pneumatic clean coal sludge pump R & D promotion Mine underground gasification technology QYF20-30 pneumatic dredging sewage pumps, to achieve "physical coal" to "chemical mining" change; develop hypothermia, efficient and clean combustion of coal-water slurry of new industries, "solid coal" to " liquid coal "change; the orderly development of modern coal chemical industry, to achieve the transition from coal to fuel feedstock. QYF17-20, QYF25-19, QYF10-20 clear silt pneumatic pump to carry coal production and consumption of green services. Efficient and clean use of coal to provide services, from exploration, design, build wells to operate the full range of "housekeeping" services to other coal companies to build mining equipment remanufacturing equipment manufacturing industry as the core group, Pneumatic clear mud pump provide users with the development of green energy and green energy finance lease, loan guarantees and other financial services. I. Overview This product is the use of vacuum principle, the slime material slurry suction tank, using air pressure to drain away the material, its advanced aerodynamic concepts make mine pneumatic vacuum dredging two sewage pumps up to international standards, Main features: 1, 3 pure gas, no-load operation without any harm to the pump, and stable performance 4, to pumping high concentrations of solids slurry and loose 5, all stainless steel, acid corrosion, wear three main Technical parameters Model flow into the feed concentration lift the whole weight of gas consumption QYF20 / 30 (A) 30m 20m3 ≤10% ≤2.5m3 / min 82kg QYF20 / 30 (B) 30m 20m3 ≤30% ≤3.5m3 / min 370kg QYF20 / 30 (C) 30m 20m3 ≤50% ≤5.5m3 / min 1000kg
