YK-500 vehicle-mounted water well drilling rig is a 6*4 self-propelled special drilling equipment developed to meet the needs of water conservancy and foreign users. The drilling rig is a positive circulation rotary drilling rig, which can drill in Quaternary strata such as clay layers, sandy soil layers, weathered layers, and bedrocks. It is mainly used for hydrogeological surveys, industrial and agricultural water well drilling, underground tunnels, and ventilation holes. construction. If the

when opening the hole, the first with small impact work, propulsion force and low speed drilling, in order to facilitate the needle positioning,(need to dust, give the appropriate water to reduce dust) when the needle drilling 10 cm or so, and then with the full throttle impact, and appropriately increase the propulsion force, improve the speed,(need to dust the gas water mixture to maintain the appropriate proportion), normal rock drilling work, drill a drill The rod should stop the operation o

What is the working principle and stress analysis of grooved drill pipe Grooved drill pipes are still widely used in the coal mining industry, because a lot of excavation and exploration are required, so the requirements for drill pipes are high. Today, the editor will tell you about the working principle and stress analysis of grooved drill pipe? Grooved drill pipe The grooved drill pipe is a spiral transport groove set on the surface layer of the drill pipe. Under the premise that it does n

What are the precautions for the use of geological auger pipes Auger pipe is still used more frequently in excavation projects, and it is also relatively easy to use. It exists and is used in many projects. Today, Xiaobian will tell you about the use of geological auger pipes. What are the precautions? Auger Rod 1. When using the first drilling and excavation, it is necessary to "grind new buttons" first, which includes applying the technical innovation of screw oil first, and then using the
