Water Well Drilling Rig Dth Hammer

 

 

A water well drilling rig equipped with a DTH (Down-The-Hole) hammer is a specialized piece of equipment used to drill water wells by utilizing the DTH drilling method. This method involves using compressed air or drilling fluid to power a DTH hammer, which in turn delivers high-velocity impacts to a drill bit to break through rock or other geological formations and create a water well.

 

 

Disassembly of the impactor

• 1. Once the impactor is disassembled, it will be difficult to distinguish which end is the front joint end and which end is the rear joint end, so do some work on the outer sleeve.
• Make marks to identify the location of the front and rear connectors.
• 2. Remove the front joint, bit and retaining ring from the outer sleeve.
• 3. Remove the retaining stop ring and "O" ring from the drill bit shank.
• 4. Remove the front joint from the drill bit.

  

   

• 5. Remove the rear connector from the other end of the outer tube.
• 6. Remove the check valve and reverse valve spring.
• 7. Remove the gasket.
• 8. Grasp the head of the valve rod and pull the cylinder of the valve rod out of the outer sleeve. Sometimes it is necessary to install the outer casing before
• Use a copper rod at one end of the joint to gently tap the end of the valve rod to disassemble the valve rod assembly and the outer cylinder.
• 9. Remove the cylinder from the valve seat. The preferred method is to align the valve rod and cylinder assembly with the small diameter of the piston.
• Match the ends together, lift the assembly high and hit the piston downwards. At this time, the cylinder will be removed. It should be noted that
• Put your fingers into the holes in the cylinder to prevent them from being pinched when the assembly moves up and down.
• 10. Turn to the end of the front connector and remove the guide sleeve from the outer sleeve of the impactor. due to corrosion of the part or
• If the guide sleeve is relatively dry, a special pull rod is required to remove the guide sleeve. When using this tool, do not hook the tool into the snap ring.
• Sometimes the guide sleeve can be loosened by banging the outer sleeve against a piece of hardwood.
• 11. Take out the piston from the outer sleeve. Because the piston is heavy, be careful when taking it out.
• 12. During daily maintenance of the impactor, it is not necessary to remove the valve rod from the valve seat. If the valve rod is worn due to
• When the valve rod is damaged and must be removed, you can use a hydraulic press or a hydraulic press to remove the valve rod from the lower end of the valve rod. Press it out. The disassembly of the impactor ends here.
