Baler GB46 reverse circulation structure drilling rigs used 132.40.1120 three row roller slewing bearing

The so-called reverse circulation drilling rig refers to when working, the rotating disc drives the drill bit to cut and break the rock and soil in the hole. The flushing fluid flows into the bottom of the hole from the annular gap between the drill rod and the hole wall, cools the drill bit, and carries the cut rock and soil drilling slag back to the ground from the inner cavity of the drill rod. At the same time, the flushing fluid returns to the hole to form a circulation. Due to the much smaller diameter of the inner chamber of the drill pipe compared to the wellbore, the mud and water inside the drill pipe rises much faster than the normal circulation. It is not only clean water, but also can bring drilling slag to the top of the drill pipe and flow to the mud settling tank, where the mud is purified and recycled for use.

The principle is to place the drill pipe into a borehole filled with flushing fluid, and use the rotation of the rotary table to drive an airtight square transmission rod and drill bit to cut rock and soil. The compressed air is sprayed out by the nozzle at the lower end of the drill pipe, and the cut soil, sand, etc. form a lighter mud sand water gas mixture in the drill pipe than water. Due to the combined effect of the pressure difference inside and outside the drill pipe and the momentum of the compressed air, the mud sand water gas mixture rises together with the flushing fluid, and is discharged into the ground mud pool or water storage tank through a pressure hose. Soil, sand, gravel, and rock debris settle in the mud pool, and the flushing fluid flows back into the manhole.
