Down the hole drill pipe DTH drill pipe Drill pipe is hollow, thick-walled, steel piping that is used on drilling rigs to facilitate the drilling of a wellbore and comes in a variety of sizes, strengths, and weights but are typically 30 to 33 feet in length. They are hollow to allow drilling fluid to be pumped through them, down the hole, and back up the annulus. It is designed to support its own weight for combined lengths that often exceed 1 mile down into the Earth's crust. Used drill stem is often sent to a yard for inspection, sorted, and stored until new drill sites can be explored. 1.Size: 2 1/2'', 2 3/4'', 3'', 3 1/2'', 4'', 4 1/2'', 5'', 5 1/2'', 6'', 8'', 10'', 10 3/4''; 2.

The water well drilling rigs for sale timely adjustment propulsion size, to make hydraulic rock drill rotary resistance timely down torque of the rotating mechanism slightly lower. Performance of hydraulic rock drill rotary speed is another important parameter, which affects the impact crusher each time breaking rocks the size of, but also affect the size of the rotary twist cut the amount of rock breaking, so that the chisel-speed changes. The turning mechanism of the hydraulic rock drill are almost independent of the impact mechanism, its performance parameters punctured speed impact, mainly because it will enable the variation of the propulsion force. We summarize the truck mounted drill rigs experimental laws: (1) Impact performance parameters, the rotary speed is constant, the thrust force is increased, rotation torque increase, within a certain range, the punctured speed increased, but the optimum propulsive force up to a maximum point later, then increase in the propulsive force slowdowns make the punctured. Hydraulic drilling machine having a rotary torque value, i.e., can reach the level of the maximum torque value on the rock drilling process to blast hole drill rigs for sale ensure optimum propulsion role. (2) hydraulic rock drill propulsive force constant impact performance parameters and drilling, hydraulic crawler drill for sale hydraulic rock drill Best Drilling speed best speed and torque with engine speed to improve and improve. (3) transfer the braze speed and drilling hydraulic rock drill propulsion unchanged by the impact energy has little effect on the actual output torque. Raise awareness of the importance of crawler drill rig rotary hydraulic rock drill performance, should be in product development, manufacturing and use of hydraulic rock drill the rotary performance as an important indicator of.
