摘要
高浓度尾矿浆长距离、大流量管道输送的关键设备是往复式隔膜泵,隔膜泵的功率计算尤为重要。目前泵功率计算影响因素多、方法复杂。为简化隔膜泵功率计算并为管道输送方案优化提供便利,在统计大量SGMB、DGMB系列隔膜泵输送尾矿浆、化工料浆、水煤浆及氧化铝料浆4类料浆时的额定功率、流量、压力数据基础上,结合Origin软件,对不同结构、不同输送对象隔膜泵的额定功率与额定流量及压力间的关系进行拟合分析,得到经验公式并进行了差异性分析。结果表明,隔膜泵的功率与额定流量和压力之积成正比,且不同结构、不同输送对象隔膜泵的功率经验公式差异程度低,因而可使用统一的隔膜泵功率计算经验公式。
In the high concentration tailings pulp pipeline transportation with long distance,large flow,reciprocating diaphragm pump is the key equipment,and its pumping power calculation is particularly important. At present,there are many factors affecting the calculation of pumping power,and the calculation method is complex,which leads to the difficulty of the section of pump scheme. Diaphragm pump power calculate method is simplified,and convenience in support of equipment preselection is provided. Based on huge amounts of the SGMB and DGMB power data collected from industrial transportation of tailings paste pulp,chemistry pulp,coal water mixture pulp and aluminum oxide pulp,using relevant mathematical software to process fitting analysis between diaphragm pump power rating,flow rating and pressure of different type and transportation object to figure out its obscure correlation,a concise power formula is obtained. Research results indicates,the product of rating flow and pressure is in a certain range,diaphragm pump application type and transportation object does almost no influence on the power formula,thus,the similar diaphragm pump power equation can be uniformed.
