引言液压冲击器是利用压力流体推动活塞高速往复冲击钎子进行破碎岩石的一类机械。在发展液压技术的过程中,人们曾力图克服由液流力等的作用而引起的液压系统的振动,以提高系统的工作质量。与此同时,人们发现如果使液压振动按一定规律产生和传递则可成为一种新的能量传递方法,这就是液压振动技术。 Introduction Hydraulic impactor is the use of pressure fluid to promote high-speed reciprocating impact of the piston on the rock broken rock a class of machinery. In the process of developing hydraulic technology, attempts have been made to overcome the vibration of the hydraulic system caused by the effects of liquid flow and the like to improve the quality of the system. At the same time, people found that if the hydraulic vibration generated and delivered according to certain rules can become a new energy transfer method, which is the hydraulic vibration technology.
