Chuck and speed reducer assembly including:Speed reducer: Ratio 2.2: 1Chuck and guide sleeveHydraulic motorWorking pressure: 20MpaMaximum pressure: 25 MpaTheoretical drainage: 80ml/r, the minimum drainage 35ml/r2. Holder assembly3. Bed bodyOil cylinder in bed body adopt GG012-80/40x800x1060Chain adopt 1# and 1 1/4# two kinds of bush roller chain.Power handcartPower handcart is composed of the following parts:1. Y series three-phase squirrel-cage asynchronism motorVoltage: 380 VFrequency: 50 HzRotational frequency: 1480 r/minPower: 55Kw2. High pressure axial plunger pumpMotor oil way plunger pump(main pump)Rated pressure: 31.5 MpaTheoretical drainage: 800 ml. /r(90% of the oil pump drainage)Max. Theoretical torque: 439.6 NmFeed oil cylinder oil way plunger pump(service pump)Rated pressure: 31.5 MpaTheoretical drainage: 10.9 ml/rMax. Theoretical torque: 54.8 Nm3. Oil filterFiltration accuracy: 10 μ M4. CoolerOil pressure: 1.6 Mpa(max)Water pressure: 1 Mpa(max)5. Relief valveRated flow: 401/minAdjustment pressure scope: 16-32 MPa6. Electrical drive pump for hydraulic oil refill: Used for adding hydraulic oil7. Walking wheelOutstanding features:Unmatched high drill head and spindle speed, which allows high drilling speedFull hydraulic driven and control system, including:Hydraulic rod feeding, pushing and pulling system;Hydraulic rod rotation driving system;Superior quality key components made of aircraft grade materials, fabricated withProfessional aircraft industry machinery;Power supply can be made by electrical motor/generator assembly.Drilling angle adjustable between 0° And 360°Advanced winching systemFlexible rotation base frame. Can easily change the direction by rotating the baseDesign.Secondary hydraulic oil filter. To make the filtration for hydraulic oil more safe, we setUp the secondary filter in the chuck which will shows as a red point.Magnetic prevention for hydraulic oil. Even if we have the first stage filtration forHydraulic oil from the oil tank, but we also set up the strong magnetic on the tank toAbsorb any chips so as to avoid it goes to next step.Oil temperature sensor. In order to keep the temperature of hydraulic oil at safe level,We configures with the temperature sensor in the flow to monitor and feedback duringThe work.Electrical work recorder. We configure with this electrical recorder so that there will beClear record and report to check how much work has been done.4 shifts design. High and low shift by stepless shift change For hydraulic shift modeTwo shifts for mechanical shifts mode.More advanced, more humanized, more optimized design for whole working system.Drilling depth(m)Hole Dia.(mm)Rod Dia.(mm)Material of Rod3809589Steel4807571Steel6005955.5Steel
