摘要
本文通过研究湍流发生器剪切作用原理及气泡在湍流发生器中的运动轨迹上,提出了中浓纸浆泵湍流发生器重要尺寸的计算方法。对一款中浓纸浆泵的湍流发生器进行设计,并且搭建了一种基于声呐流量测试系统的中浓纸浆泵性能试验台,研究分析了纸浆浓度为7.52%,9.3%,12.1%,转速为960 r/min,1140 r/min,1500 r/min和不同排气抽吸真空度时,泵的扬程、效率、出口含气率量变化特征。通过试验验证了设计方法的正确性,为今后中浓纸浆泵湍流发生器的设计提供依据.
Outer diameter and axial length is an important geometric parameters of turbulence generator. Based on turbulence generator shearing action principle and movement of bubbles in the turbulent generator, The present work puts forward a turbulence generator calculation method of critical This article through studies the turbulence generator shearing action principle and movement of bubbles in the turbulent generator, put forward the consistency pulp pump turbulence generator the calculation method of critical dimensions. A turbulence generator is designed. A MC pump test bed was established using sonar flowmeter and monitoring system. The head, efficiency, gas fraction and max flow rate were studied with pulp concentration 7.52%, 9.3%, 12.1%, speed 960 r/min, 1140 r/min, 1500 r/min and different degas vacuum degree at vacuum housing. The design method is validated by experiment and provides the reference for design of turbulence generator.
