EBZ-132悬臂式掘进机水系统改进

目前,山西焦煤集团公司使用的EBZ-132悬臂式掘进机泵站主要由75 kW电机、组合变量双泵组成,水系统承担液压系统、截割电机、截齿冷却和喷雾灭尘作用。但是由于单进水平提高,冷却效果欠佳,经常造成油箱内油温过高而不能正常起动掘进机,停机待油温下降后再起动,影响正常进度。官地矿经过现场分析,设计研制出该掘进机油箱辅助水冷却系统。

Improvement on Water System of EBZ-132 Cantilever Type Roadheader

At present,Shanxi coking coal group is now used by EBZ-132 roadheader pumping mainly by the 75 kw motor,a variable combination of the composition of pairs of pumps,the water system to take over hydraulic system,cutting electrical,cooling and spray pick eliminate dust effect.However,due to raise the level of single-entry,cooling is ineffective and often result in excessive oil temperature of the fuel tank failed to work properly start heading machine,stopping when the oil temperature down and then start affe...
