””””The resonance pulse mozzle of step type is a high efficient
nozzle,mainly used for various kinds of tri-cone bit.It is able,without
any auxiliary devices,by relying on itself oscillation chamber,to
change the continuous jet stream into pulse jet stream.thus,increasing
the rock crashing action.By using this nozzle,the instantaneous
impact of the injection will be increased by 17-20 times,the
effective injection distance,by 1.5-2.0 times and volume of
rock ablation ,by 2-4 times than by using those ordinary continuous
injection nozzles.
””””This product is made of solid carbide and precisely machined.lt
is sealed by”°O”±ring and tightly positioned by calibre.lt is
convenient to use, reliable and interchangeable.lt has no special,requirement
for operation at work site and data design.
Nine(9)kinds of hydraulic diameters of 8-16mm are available. |
