Hydraulic DTH hammer

Hydraulic DTH hammer, hydraulic shock or hydraulic hammer), is the impact load of hydraulic impact rotary drilling device, its use in the process of drilling mud pump rinses the energy supply of direct drive hydraulic hammer impact hammer form up and down reciprocating motion in [1], and continuously impose a certain frequency of impact load on the lower drilling tools, So as to achieve impact rotary drilling.

Hydraulic DTH drilling is a great reform of conventional rotary drilling and a new drilling method after modern diamond drilling and air drilling. It is an effective drilling technology to solve the problem of low drilling efficiency and poor drilling quality of hard rock and some complicated rock strata by making good use of the weakness of hard rock with great brittleness and low shear strength.

Compared with conventional rotary drilling, hydraulic DTH drilling has the following advantages:
(1) Make full use of conventional on-site supporting equipment and basically do not change the existing operating procedures;
(2) Because the pump pressure of the mud pump is easy to reach a higher value, so the hydraulic hammer ADAPTS to a larger hole depth;
(3) The hard rock formation has high drilling aging;
(4) The broken stratum is not easy to plug, and the footage length is returned;
(5) Effectively prolong the bit life;
(6) Reduce the hole oblique strength to a certain extent;
(7) Lower energy consumption and less environmental pollution;
(8) Not afraid of aquifer, strong wall protection ability;
(9) Easy to operate and maintain .
