Easy access to safe, potable water is a basic human need, important for health and quality of life. A statement like this is regarded now as being something of a cliché. However, it must be said that even with the growing prevalence of water shortages throughout the world, a reliable water supply is still taken for granted, with no real thought about its sustainability and quality. This attitude is most starkly evident in areas where there is a reliance on water from boreholes, which, it is assumed, will keep on producing – at the same rate – continuously and forever. Groundwater is out of sight, and hence, largely out of mind, but it is one of the best sources of water that man has been able to utilize.
So water well drilling Equipment play a very important role when finding Groundwater to meet people's basic requests.
In air-circulation drilling, if a formation is too hard for penetration by a drag bit, a DTH hammer & Bits are generally employed. This tool was developed for the mining and quarrying industry. The ‘business’ end – the button bit – is studded with hemispherical tungsten carbide ‘buttons,’ and with channels built in to allow the passage of compressed air. When the hammer is pressed against the ground, the bit is forced into a pneumatic hammer action (like a road drill) by compressed air fed down the drill pipes. Then, as the tool is rotated in the hole, the buttons act across the entire base of the borehole. Most hammers rotate at speeds of 20 to 30 revolutions per minute, and blows can be struck at rates of up to 4000 per minute. Debris is normally flushed (blown) out of the hole at the end of each drill pipe. DTH hammers are most effective in hard rock formations such as limestones or basalts; soft, fine-grained formations tend to clog the air ducts or jam the piston slides.
Nonetheless, DTH hammers and Bits are extremely cost-effective and hence very popular with commercial drillers.
