Electro-hydraulic differential cylinder of damping hydraulic rammer compactor
The invention relates to an electro-hydraulic differential cylinder of a damping hydraulic rammer compactor. The electro-hydraulic differential cylinder integrates gas, electricity, liquid and machinery into a whole to form a differential oil cylinder, and mainly comprises an oil cylinder, an acceleration buffer cavity, an absorption storage device, a large-flow oil pipe, an integrated cylinder bottom, a differential oil way and an oil cylinder piston rod to achieve high-frequency switching action, and no impact fluctuation exists at the tail end of the stroke. Impact pressure and pulsating pressure generated by severe changes of pressure and flow of a system can be absorbed, and besides, oversupply energy can be absorbed and stored. Sharp alternate damping fluctuation of the liquid pressure in a pipeline due to hydraulic impact is avoided.
一种阻尼液压夯实机电液差动缸，该技术集成气、电、液、机械为一体组成差动油缸，其中主要包括油缸、加速缓冲腔、吸收储存器、大流量油管、集成缸底、差动油路，油缸活塞杆实现高频切换动作，行程末端无任何冲击波动；可以吸收系统因压力、流量极剧变化，产生的冲击压力和脉动压力，同时可以吸收储存供过于求的能量；避免液压冲击使得管路中液体压力发生急剧交替的阻尼波动。
