hydraulic rock drilling Exploration into Modular Design Plan for Full-Hydraulic Rock Drilling Cramp The paper concerns a modular full-hydraulic rock drilling system. With its modular design, this rock drilling system can be combined easily according to the requirements of design to meet the demands of particular drilling and excavating of the tunnels. Operating on the pressurized fluid
Circuit breaker Analysis and Improvement of Circuit Breaker Tripping Fault for a Rock Drilling Taking a drill jumbo as the background it is to analyze a failure in circuit breakers turning off for no reason.First of all it has to analyze principles of 2 sets of power supply in 380VAC and 24V DXC used in the jumbo in consideration with the principles so as to get a most optimal detecting way
drilling jumbo Test and analysis on performance of drilling arm hydraulic system of drilling jumbo The drilling jumbo is an important equipment for mining mechanization, the working performance of the drilling arm hydraulic system directly affects the operation efficiency of the drilling jumbo. After testing for the performance of the drilling arm hydraulic system, the impact, rotation
