DTH drill pipe is often used in high-strength down-the-hole drilling, so lubrication is a must. The following drilling tools manufacturer tells you the importance of lubrication.

　　The purpose of lubrication is as follows:

　　1) Anti-corrosion effect. The impact part is easily corroded by the pressurized gas in the borehole and the chemical substances in the water. The corrosion effect exists together with the parts, which will seriously reduce the strong penetration of the parts; the corrosion will further expand the cracks, and the rusted area of ​​the corrosion pit may directly damage the parts. . Therefore, avoiding corrosion is one of the important functions of lubrication.

　　2) Sealing effect. Proper lubrication can seal the moving parts of the impactor to avoid reducing the power of the impactor due to poor sealing;

　　3) Reduce the collision loss of moving parts. What's more, the excessive conflict caused by insufficient lubrication can cause tiny summer dresses on the touch surface, such as crack propagation, and damage to parts. In addition, the apparent overheating caused by excessive conflict can cause local softening and plastic deformation of the metal, which then leads to damage to the cylinder and piston.

　　Lubricant quality requirements:

　　1) High liquid film strength;

　　2) No smoke or toxic gas is discharged;

　　3) No viscous residue is formed in either cold gas or hot gas;

　　4) No corrosion phenomenon under any conditions;

　　5) It is not easy to erupt or disturb the movement of the valve plate;

　　6) It can be fully lubricated at high drilling speed, high temperature, and low temperature;

　　7) Can quickly lubricate the parts to be lubricated;

　　8) High oil quality.

　　After the above understanding, I believe everyone knows the importance of lubricating the DTH drill pipe, because the working environment of the machine is relatively harsh, and the lubrication work must be done well when using it.
