Well drilling rig What is the purpose of flushing medium at the time of production wells, drilling rig crawler drilling rig pictures, need to use flushing medium drilling, drilling flushing medium plays an important role in the well borehole drilling rig. Flushing medium in well drilling rig main purposes are: to balance the formation pressure, transmission power, portable and suspended rock flour, cool the drill bit, drill lubrication, protecting the hole wall, passing power and a series of roles that are concerned for the well drilling rig is very important. Water Well Drilling Rig different structures institutions role wells rig consists of a variety of aspects, the main role in the well drilling rig components of hydraulic pumps, masts, legs, power top, the different agencies in different plays of importance is different. As well drilling rig workers, but also need to understand the composition of the components of what different agencies have different roles. A hydraulic pump: hydraulic pumps in water well drilling rig for double-crawler drilling rig where to sell, large displacement pumps provide power for power head basis, compared with four legs small displacement pump cylinder, landing mast cylinder, lifting tackle cylinders provide power production. 2, the mast: mast drilling rig in the composition of welded steel frame construction for the giant, channels and angles to both sides of the channel in the slot for the power head under running track, so as to maintain the degree of vertical wells drilling rig crawler drilling rig, and drilling by hydraulic landing mast production is completed. 3, leg: well drilling rig contains four legs, a small drilling rig by hydraulic cylinder and fixed shelves composition, can real-time adjustment of the level of the water well drilling rig crawler drilling rig Price in work scenarios, the overall play a supporting and stabilizing Role wells rig. 4, the power head: drilling rig power head is the most important power head gear box mechanism design, its low speed shaft in the middle there is a big hole in the mandrel, the mandrel can interface with catchy hose concrete pouring equipment connected perfusion concrete action.
