Diesel Medium Shallow 30-200m Hydraulic Borewell Machine
Product Description:
Core drilling machine is a medium-shallow hole core drilling machine. It is a vertical shaft core drilling machine which is mainly engaged in diamond drilling and is suitable for various drilling process requirements. It can be matched to the corresponding motor or diesel engine. The rig structure is simple to disassemble and easy to operate. Geological survey exploration, road and high-rise building foundation exploration, various concrete structure inspection holes, river dykes, roadbed grouting hole drilling and direct grouting, civil water wells and ground temperature central air conditioning, etc.

How does a water well drill drill drill drill rock
There are more white sandstone, limestone and red sandstone. Which one is faster, core drill or water well drill, with hole neck 275. water well drilling rig is to drill underground. In the future, this hole will give water. Install a pipe to become a water well.
When drilling downward, there is a drill bit at the bottom of the drill pipe. This drill bit has several models. It is very hard. You have to grind the rock into powder easily. The middle rock does not need to be grinned. It will be lifted from the drill pipe.
In the process of drilling, the drilling machine drives the drill pipe and drill bit to rotate at high speed and pressurize downward. These two forces act on the rock and grind the rock in contact with the front of the drill bit into powder. The rock powder is filled to the surface by water and flows away.
Four functions of lubrication for water well drilling rig
1) Reducing friction: This is the main function of oil lubrication. Due to the existence of lubricating oil film, the direct contact of the metal surface of transmission parts is prevented, so as to reduce the magic friction resistance and wear loss.
2) Cooling and heat dissipation: in high-speed rotating parts, complete heat is generated due to friction. If the heat surplus is not dispersed, the temperature will continue to rise, resulting in the burning of parts.
3) If the grease is applied on the surface of the drilling machine that is easy to rust, it can prolong the service life of the metal parts that are easy to be sprayed by the rain and prevent rust.
4) sealing blockage: wool felt is installed on the sealing packing and bearing end cover to effectively seal and prevent dust due to oil immersion.
