【摘要】 对液压冲击器的结构抽象变量β,进行了更为深入的再认识,加深了对液压冲击器的规律性的理解和认识;指出,前腔常压式全液压冲击器是认识液压冲击器的原始模型,其他原理的液压冲击器都是从它派生出来的,它们之间有着非常紧密的联系;任何前腔常压式液压冲击器,都可以引入氮气,变成气液式液压冲击器（氮爆式）;前腔常压式液压冲击器,引入氮气后冲程有效承压面积,都增加了一个前腔面积A₂,从而改变了前腔常压式液压冲击器的运动规律。气液式液压冲击器系统中都包含两个独立变量:泵的排量和氮气室的充气压力,它们都可以独立调节,以改变系統的输出。β=-1的前腔常压式液压冲击器,没有使用价值,必须对其系统和结构进行较大的改造,才能变成理论和结构创新的新型液压冲击器——单管柱塞式液压冲击器。更多还原

【Abstract】 A deeper understanding of the structural abstract variable β of the hydraulic impactor has been carried out, which deepens the cognition and understanding of the regularity of the hydraulic impactor. The result shows that hydraulic impactor with the front cavity constant pressure is the original model to recognize the hydraulic impactor.Other principles of the hydraulic impactors are derived from it. There is a very close relationship between them. Any front-cavity atmospheric pressure hydraulic impactor can become a gas-liquid united hydraulic impactor(nitrogen explosion type) after introducing the nitrogen. Hydraulic impactor with the front cavity constant pressure, has an effective pressure bearing area for stroke after introduction of nitrogen gas, which increases the area of an anterior cavity A2, thus changing the motion law of hydraulic impactor with the front cavity atmospheric pressure. The gas-liquid united hydraulic impactor system contains two independent variables, the displacement of the pump and the inflation pressure of the nitrogen chamber, which can be independently adjusted to change the output of the system. The anterior chamber pressure type hydraulic impactor with β=-1 is useless. It is necessary to carry out a major transformation of its systems and structures in order to become a new type of hydraulic impactor with a theoretical and structural innovation——a single-tube plunger-type hydraulic impactor.更多还原
