Pulsating flow hydraulic system (PHF) which uses the vibration of oil liquid to transfer power is different from conventional hydraulic system. Because of the alternative pulsation of liquid, it's necessary to calculate the vibration characteristic such as amplitude attenuation of pulsating quantity and degree of phase lag at the output and transmission efficiency of the system exactly when the PFH...
The impact energy of the traditional hydraulic impactor can be regulated manually between the second and the third grade, and its impact frequency can not be adjusted independently. Also, they have to stop working for adjustment. In order to alter this situation, a new hydraulic impactor DBS500, which controlled by micro-electronic system, has been designed and its functions are showed as following:...
