液压支架用乳化液热稳定性快速测定研究

Study on thermal stability rapid measurement of emulsion applied to hydraulic powered support

针对液压支架用乳化液热稳定性现行测定方法存在周期较长、目视检测不易定量等问题,研究了以粒度组成数据为基础,建立液压支架用乳化液热稳定性快速测定方法的可行性。试验测试了2种不同系列液压支架用乳化液的粒度组成,计算出油性颗粒的沉降高度,并与现行测定法油皂分层厚度进行了比较。试验结果表明:通过粒度组成数据计算油性颗粒沉降高度,进而测定液压支架用乳化液热稳定性的方法可行;油性颗粒沉降高度与液压支架用乳化液的热稳定性有关,沉降高度越大,液压支架用乳化液热稳定性越差;沉降高度越小,液压支架用乳化液的热稳定性越好。

According to a long period,a hard quantitative of the visual test and other problems existed in the available thermal stability measuring method of the emulsion applied to the hydraulic powered support,based on the data of the particle size composition,a study was conducted on the feasibility to set up a rapid thermal stability measuring method of the emulsion applied to the hydraulic powered support.The particle size composition of the two different emulsions applied to the hydraulic powered support was tested and measured,a settlement height of the oily particle was calculated and a comparison was conduced with the oil soap slice thickness measured with the available measuring method.The experiment results showed that with the data of the particle composition,the settlement height of the oily particle was calculated and thus the method to measure the thermal stability of the emulsion applied to the hydraulic powered support was feasible.The settlement height of the oily particle was related to the thermal stability of the emulsion applied to the hydraulic powered support.The higher the settlement height was,the poorer thermal stability of the emulsion applied to the hydraulic powered support would be and the lower settlement height was,the better emulsion thermal stability applied to the hydraulic powered support would be.
