water well dth hammer is a drilling tool used in the construction and mining industries to create boreholes or wells. These hammers are specifically designed for drilling into hard rock formations and can be used in water well drilling projects. Here's how a DTH hammer works in the context of water well drilling:
Basic Components: water well dth hammer consists of several components, including the hammer itself, drill bits, drill pipes, and an air compressor.
Drilling Process: Here's a simplified step-by-step process of how a DTH hammer works in water well drilling:
a. Preparation: The drill pipe, equipped with a water well dth hammer and drill bit, is connected to the drilling rig. The water well dth hammer is positioned above the target drilling area.
b. Air Supply: An air compressor is used to generate high-pressure air, which is directed through the drill pipe and into the water well dth hammer.
c. Impact Mechanism: The DTH hammer has an internal piston that rapidly moves up and down when compressed air is introduced. This piston strikes the back of the drill bit, generating high-frequency and high-impact forces.
Assembling
LEANOMS
1. Increase the torque on the rear top sub until the gap between the rear top sub and the outer casing is eliminated. Adjust the torque according to the diameter of the DTH Drill Hammer. Each inch requires a torque of 1500ft-lb (0.86KN.M per millimeter). For example, the outer diameter of the DHD360
DTH Drill Hammer is 6in (152mm), which tightens the front joint's torque. According to 6 (152) * 1500 (0.86) that is 9000ft-lb (131KN.M).
2. Make sure that the "O" ring on the guideed case is intact, because it can keep the DTH Drill Hammer position of the guideed case fixed when the front top sub is removed, and the guide sleeve is inserted into the outer sleeve to ensure that the guide sleeve is stuck on the outer sleeve, it may be necessary to lightly tap the two sides of the guide sleeve several times with a copper rod.
3. When installing the stop ring, first put the stop ring sideways into the outer casing. When the stop ring is close to the cutout, turn the DTH Drill Hammer stop ring to a suitable position until the stop ring is embedded in the groove of the drill bit. After installing the stop ring When using, be sure to wear eyeglasses to prevent the lubricating oil from splashing into the eyes by inserting the stop ring.
4. Apply a layer of lubricating oil on the spline of the drill bit, and install the front top sub on the dth drill bit.
5. Assemble the stop ring and the "O" ring of the stop ring with the dth button drill bit and the front top sub.
6. Apply a layer of lubricating oil evenly on the thread of the front top sub, and then put the front top sub and the drill bit into the outer casing.
7. Before DTH Drill Hammer drilling, the pre-tightening torque on the front top sub must be in accordance with the specification.

Danger
LEANOMS
Explosion hazard
If a rock drilling tool comes into contact with an explosive, an explosion may occur. Explosions may cause serious or mortal injuries. To reduce such risk of explosion, never drill near any explosive, including dynamite or other explosives in the rock. Make sure that there are no explosives in the rock. Never drill in an old hole.
Drilling can cause sparks, which may ignite explosive gases and cause explosions.
Explosions may cause serious or mortal injuries. To reduce such risk of explosion, never drill in any explosive environment. Make sure that there are no undetected sources of gas.
