Brand Name: Hanfa
Key Specifications/Special Features:
HFW - A series of the all formation water well drilling rig is a kind of efficient and new type of hydraulic drill, the drill is in our ten years mines, wells, trenchless, pile holes, core drill based on the working experience in manufacturing and construction of independent research and development, in view of the complex formation design, satisfy the formation drilling, is replace the current single small aperture of rock drill, reverse circulation drill, normal circulation drill patent productPatent number: 201520496371.3, widely used in all strata drilling pile sinking wells, small hole constructionAlso can be applied to the mine rescue drill, large mining blasting hole construction, is domestic initiative,constructiontechnologicalis the strongest comprehensive water well drilling rig:1.Innovation technical, patent combined DTH hammer and three-wall drilling pipeThree-wall drilling pipe is adopted in this technologyIn the middle is a pipe to transmit the air for percussion of DTH hammer and first annular is used to exhaust to the surface for DTH hammer independentlySecond annular is normal circulation for mud travels to the bottom of the hole and the mud travels back to the surface around the outside of the drill pipeThis is combined the normal circulations of air and mud drilling technology for small diameter (below 300mm)
Also adopted three-wall drilling pipe and cluster type combined DTH hammer
In the middle is the pipe for water reverse circulation to up the cuttings
First annular is air-power for DTH hammer for percussion and the second annular is for exhausting of DTH
This technologyis used for deep (200m) big diameter (400-3000mm) hole
2.Filltheblanksoflarge diameter and deepdepth waterwell,pileholeinrocklayer
(1) Traditional water reverse circulation drilling technology is only suitable for soil layer
(2) Traditional mud normal circulation drilling technology is widely used for mud rock, limestone and strong weathered rock with slow drilling speed (for example a well with 300mm diameter, 400m depth usually takes 6-12 month) and it’s not suitable for rock layer and weakly weather rock
(3) Traditional DTH hammer of air normal and reverse circulation drilling technology is used for rock layer and weakly weathered rock with high equipment investment and oil consumption (for example if a well with more than 400 in diameter at the depth of 200m, 2-3 air compressors are needed)
(4) HANFA “air be only for percussion purpose and no deslagging” technology
In this technology, the DTH hammer can drill in soil and rock layer for water well and pile hole
In rock, rock weathering, boulder formation, this technology can drill 400-600mm diameter 200m
Also adopted three-wall drilling pipe and cluster type combined DTH hammer
In the middle is the pipe for water reverse circulation to up the cuttings
First annular is air-power for DTH hammer for percussion and the second annular is for exhausting of DTH
This technologyis used for deep (200m) big diameter (400-3000mm) hole
