Comparative Study Between The Alternative Used By The IMP Type Pecussion Drills And The Version Using Fluid Elements Regarding The Supplying, Command And Automatic Adjustment Systems Of The Injection Water Pressure

Starting from analyzing of an existing solution regarding the injection water feeding system for the pneumatic rotating and percussion drilling installations, which is included in the structure of the perforator installation (IMP-1or IMP-2), the paper presents part of a research regarding an original solution of the automatic command and regulate with monostable fluidic elements, with different physical nature jets. This solution is applicable to this drilling installations type, made in Romania.
