Product Description Product DescriptionThe primary working principle of the air lift reverse circulation drilling rig relies on the isothermal expansion of compressed air within the liquid, which is then utilized to lift the liquid, facilitating reverse circulation drilling. To elaborate, compressed air is conveyed through a double-walled drill pipe to a designated depth within the well, where it combines with the liquid inside the drill pipe, creating a gas-liquid mixture with a density less than that of the flushing liquid. Under the influence of the water column pressure within the annular gap outside the drill pipe, this mixture ascends at a rapid pace, continuously expelling rock debris from the hole's base to the surface.The air lift reverse circulation drilling rig offers distinct advantages in construction. Firstly, its strong rock debris removal capability minimizes blockages, reduces equipment wear, prolongs drill bit lifespan, enhances drilling efficiency, and ensures high borehole quality. When operating in loose formations, it reduces the likelihood of hole wall collapses. Additionally, this drilling method is adaptable to various formations, particularly excelling in large diameter boreholes. It effectively removes rock debris from the hole's bottom, facilitating smooth drilling progress.Product ParametersTechnical parametersFSL400FSL500FSL600FSL800FSL1200Max drilling depth(M)4005006008001000Power(KW)110132132176194Drilling diameter(mm)105-305105-325105-400105-500105-800Air pressure(Mpa)1.2-3.51.2-3.51.2-3.51.2-3.51.6-8Air consumption(m3/min)16-5516-5516-5516-5516-96Drill pipe length(m)33366Drill pipe diameter(mm)89/102102/114102/114114/127127/146Air circulation double layer drill pipe diameter(mm)89/102102/114102/114114/127127/146Axial pressure(T)6771113Lifting force(T)2225294757Fast lifting speed(m/min)2023292930Fast feeding speed(m/min)3233284244Max rotary torque(Nm)8000/400010000/500012000/600018000/900024000/12000Max rotary speed(r/min)75/15075/15075/15070/14086/172Small secondary winch lifting force(T)1.51.52.52.52.5Jacks stroke(m)1.61.61.61.61.7Drilling efficiency(m/h)10-3510-3510-3510-3510-35Moving speed(km/h)2.52.53.556.4Uphill angle(Slope)21°21°21°21°21°Weight of the rig(T)111212.51723Dimension(M)6.32*1.7*2.396.32*1.7*2.396.52*1.85*2.516.73*2.1*2.637.3*2.25*2.75Working conditionUnconsolidated formation and stone headDrilling methodTop drive hydraulic rotary and pushing, hammer or mud drillingMatched DTH hammerMedium and high air pressure seriesOptional accessoriesMud pump,Centrifugal pump,Generator,foam pumpDetailed Photos Packaging & ShippingCertificationsCompany Profile FAQ1.
