The difference between a pneumatic water well drilling rig and a mud pump water well drilling rig.
A pneumatic water well drilling rig (referred to as a pneumatic water well driller) is also known as a hammer well drilling rig. Compressed air is used as both a washing medium and energy for broken rocks. It is also a kind of impact drilling method, which is similar to liquid impactor drilling technology. The main advantage is that it can effectively improve the drilling process for pebble layers and hard rock. The drill bit life is long and prevents the sloping hole, and its drilling pressure is small, with low torque, low swing speed, and high flushing medium flow.
The so-called pneumatic well drilling rig is a kind of process to drill and break rock and a pneumatic device that can produce impact while drilling. This pneumatic device is an impact hammer and is a wind tool powered by compressed air. It produces the impact energy, which can be directly transmitted to the drill bit, at the same time the drilling rig drives the drill pipe rotating, forming the ability to break the rock. The compressed air from the impactor cools the drill bit and blows powder out of the water well. Therefore, pneumatic hammer drilling can wash water well, it is special for drilling into dry and water shortage areas and serious leakage ground formations.
The difference between a pneumatic water well drilling rig and a mud pump drilling rig:
A pneumatic drilling rig generates up to dozens of kilograms meters of impact, or even more than 100 kilograms, it is the current liquid impactor impact work more than ten times – dozens of times. Therefore, from the point of view of rock fragmentation, the pneumatic drill is mainly to impact the broken rock, and the swing is only to change the position of the impact rock while playing the role of auxiliary crushing rock. Therefore, drilling efficiency is high.
