综采机组所包括的采煤机、支架和输送机的可靠性和使用寿命是影响综采机组运转稳定性和使用效果的主要因素。而乳化液的质量是延长液压支架液压系统的使用寿命和保证可靠性的主要条件之一。鉴于液压系统广泛使用乳化液代替易燃并且昂贵的液压油,当务之急是提高乳化液的使用性能。通过这一途径可以明显地提高井下液压支架、端头支架和移溜器液压系统的使用效果。由于井下开采条件逐趋复杂,在煤矿机械制造部门有一种提高液压支架承载能力以及综采机组液压系统向更高压力过
The reliability and service life of shearer, support and conveyor included in fully mechanized mining units are the main factors that affect the stability of operation and the effect of use of fully mechanized mining. The quality of the emulsion is to extend the service life of hydraulic support hydraulic system and ensure reliability of the main conditions. In view of the extensive use of emulsions in hydraulic systems to replace flammable and expensive hydraulic fluids, it is imperative to improve the performance of emulsions. Through this approach can significantly improve the underground hydraulic support, end bracket and the use of moving the hydraulic system. Due to the complexity of downhole mining conditions, in the coal mining machinery manufacturing sector there is a way to improve the bearing capacity of hydraulic support and the hydraulic system of fully mechanized mining units to higher pressure
