Rand tells you how to handle the drilling of engineering rigs

Rand Heavy Industry, designing the drill bit for your arduous construction is the most important part of the engineering rig. During the progress of the project, the drilling boring phenomenon of the engineering drilling machine may happen occasionally. Knowing the cause of the drill slip, you can take the corresponding treatment. The timely treatment of this phenomenon has been more rational and efficient use.
First combine the depth of the single bucket on the display. Although the drilling resistance of the mud layer is small, as the internal dirt of the drill pipe grows, resistance to the slag inlet will be generated, so the drilling resistance is promoted, and the sound of the planetary reducer on the power head changes with the resistance, and the sound of the power head is auditioned. Can decisively increase the amount of footage, when the drilling resistance increases, the speed of the power head is also low, so the speed of the drill pipe can also be decisive. When the drilling rig uses the wear-resisting rod to drill into the water-pile layer, it is necessary to go through the depth of each bucket. The single bucket is too deep. At this time, the bucket is filled with dirt, and the soil that has been drilled under the cutting is nowhere to be accommodated. At the time, the tooth has lost the cutting effect. Under the lubrication of mud or water, the drill can not be drilled continuously. Therefore, when the bottom of the bucket is reversed, the bottom of the bucket has no resistance at all, so the bottom will be Reversed with the drill and cannot be closed.
