ST 300 Steel Crawler Mounted Commerical Water Well Borewell Machine Equipment
ST 300 Pneumatic Borewell Machine Introduction:
ST 300 drilling rig is efficient and multifunctional drilling equipment , It has 300 meters drilling depth,300mm hole diameter. It is especially suitable for water intake in mountainous and rocky strata.is especially suitable for water intake in mountainous and rocky strata.Pneumatic water well drilling machine should be used together with air compressor, it can add mud pump and foam pump. Need to use different drilling tools such as: drill rod, hammer, rock drill bits, etc.

ST 300 Pneumatic Borewell Machine Advantages:
The rig can create drilling jobs in different strata, borehole diameter can up to 245-294mm. The rig with hydraulic technology,supporting high torque hydraulic motor rotation and large bore hydraulic cylinder push, the multi cylinder engine of famous factory provides power for the hydraulic system.
How to deal with the soil layers encountered by the water well drilling rig?
When the pneumatic water well drill encounters different geological layers during drilling, different methods should be adopted to achieve good results. There are also different geological layers, such as quicksand layer and gypsum layer. In case of gypsum intrusion during the drilling process of pneumatic water well drilling rig, calcium ion can be removed by means of soda ash, calcium removal, viscosity reduction, etc. At the same time, the viscosity reducer with strong calcium resistance can be used to control viscosity reduction and make up for the lack of filtration loss reducer, anti sloughing agent and other materials.
Operating Instructions:
During the working process of water well drilling rig, the pump is used for reverse circulation operation. Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank to the bottom of the well through the return ditch along the annular gap of the well. At this time, the rotary table drives the drill pipe to drive the drill bit to rotate for drilling. The negative pressure established by the suction of the mud pump sucks the debris mud into the inner cavity of the drill pipe and discharges it into the sedimentation tank through the mud pump. The circulating fluid after sedimentation continues to flow into the well, The reverse circulation drilling work is formed.
