Fault Diagnosis Research on Impact System of Hydraulic
In the production and manufacturing process of hydraulic rock drill, there are small impact energy and low impact frequency, and a fault diagnosis method based on the internal mechanism testing and testing of the hydraulic rock drill is proposed. This method is used to test the change law of hydraulic oil in the rock drill, by retaining the test speed of the centrifugal impact crusher. The kinetic energy of collision of the particle on the impact plate of the crusher at the velocity υ equals the work Ac implemented by the dynamic interaction force Pd to compress the particle under impact, ε. The value of ε is equal to displacement of the particle inertia center. At the end of impact,Metallurgical Slag Disintegration in Centrifugal Impact
