QYF25-20 Mine pneumatic dredging sewage pump, QYF25-20 pneumatic dredging sewage pump, QYF25-20 Mine pneumatic dredging sewage pump technology leader, QYF25-20 Mine sewage pump pneumatic dredging assured opt good, pneumatic dredging sewage pumps, mining dredging pump, QYF mining dredging pump, coal dredging pumps, pneumatic pump dredging, dredging pump as the whole pneumatic coal-based energy company, QYF25-20 type Mine pneumatic dredging sewage pump Shandong Energy proposed and implemented a "green coal" strategy, focus from coal mining, washing, transport, transformation, use the full life cycle of the start, to take "greening" measures from four aspects. Dredging sewage pump pneumatic propulsion green black coal mining. Promote the implementation of waste - filling replacement coal technology, surface subsidence new mining area is close to zero, to prevent the formation of a new waste dump, but also eliminate some of the waste dump left over by history. Promote the development of high-carbon low-carbon industry. QYF mining of coal and associated dredging pump adhere to jointly develop bio. Promote the use of traditional energy sources clean. Continue to increase the intensity of coal washing, coal to sell coal to sell to achieve change. QYF25-20 Mine pneumatic dredging sewage pump conditions: a) by suction dredging pump intake pipe submerged. b) transport medium temperature does not exceed 40 ℃. c) Operating ambient temperature (5 ~ 40) ℃. d) PH transmission medium within the range of 4 to 10. e) the maximum diameter of solid particles containing no more than 20mm. e) applies pressure range 0.60MPa ~ 0.70MPa.
