Working principle of Dth Hammer

2024-07-19

The working principle of Dth Hammer mainly involves compressed air driving the piston to reciprocate in the cylinder, thereby generating impact energy, which is ultimately transmitted to the drill bit for drilling operations. Specifically:

Advantages of Dth Hammer

2024-07-19

High efficiency: The advanced design of Dth Hammer can provide ideal energy transfer, large single impact power and fast rock drilling speed, thus significantly improving drilling efficiency. ‌In addition, ‌its unique taper diameter-reducing design‌can reduce the lifting resistance when the drilling rig is lifted if gravel and soil are stuck when drilling,‌which greatly reduces the impactor's inability to lift. Out of the fault occurs, ‌ further ensures work efficiency. ‌

Introduction to the principles of heat treatment process selection for H22 drill rods, come and collect them!

2024-07-19

H22 drill rods are tools that connect drill bits and rock drills in tunnel engineering. H22 drill rods used in mine tunnel engineering are generally hexagonal hollow steel and hollow round steel. The inscribed circle diameter of hexagonal hollow steel is 22mm and 25mm, and the outer diameter of hollow round steel is 32mm and 38mm. Steel drill rods are finished steel and forged steel. Finished drill rods are forged to a certain length, and then the drill bit is directly installed to drill holes.

How to buy a trolley drill rod?

2024-07-19

Understand the characteristics of the drill rod. The trolley drill rod is a drill tool that uses an alloy steel pipe to thicken the upsetting heads at both ends, turn the small pitch tapered thread, and connect it with a locking joint. It is used in the field of geological exploration to transmit the drilling torque to the bottom hole drill bit and is responsible for transmitting the drilling fluid. Common connection methods include male and female connections (tapered threads) and joint connect
