We provide you the best water well drilling rig, all of them is multifunctional, there are 3 kinds of drilling method:
1. Dry hydraulic air drilling rig method, it needs a screw air compressor to drill.
2. Water hydraulic drilling rig method, needs a mud pump to pump water into the drilling hole.
3. Air drilling method and water drilling method integrated water well drilling rig machine. It can drill by a screw air compressor and mud pump, you can choose to use one of the drilling methods based on the geological condition.
For dry hydraulic air drilling rig method, it is mostly for drilling water wells in the rocky geological condition in the ground. The jackhammer system powered by a screw air compressor will produce the percussion power, and the drilling bit installed at the end of the jackhammer system will be like a hammer that hits the rock into thin pieces while rotating. The air produced from the screw air compressor will blow the rocky dust out of the water well. This kind of water well drilling method is not that inexpensive but very efficient.
For water hydraulic drilling method, usually drills water well in a place where there are no hard rocks. It drills with a rotary tricone drilling bit. The mud pump will pump the water into the water well, this helps to clean the water well while drilling, washing the drilling dust out of the water well, also cooling the drilling temperature of tricone drilling bit. This drilling method is very slow but inexpensive.
For the air drilling method and water drilling method integrated, this means that the drilling rig can drill by a screw air compressor and mud pump. The users can choose the drilling method based on the geological condition.
When a user needs to buy a hydraulic crawler water well drilling rig, they need to know the geological condition here.
