matches with API standard and other Chinese industry standards.It
is durable for being produced with advanced craftwork and good
material.
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.
