Product Description

Main features: ? bzcf350zy directional and reverse circulation construction and water well drilling rig is designed by our engineers. it adopts truck mounted and is a rotary drilling rig. ? the truck chassis adopts the 6x4 special crane chassis of brand sinotruk, the main transmit, transmission power, gearbox, sets of windlass, mud pump, sewage pump,mast are set up on the chassis. ? the rig has directional and reverse circulation pump, it adopts slurry as the washing fluid, the directional circulation drilling and reverse circulation drilling can be switched by changing mud pump and sewage pump. ? the power of drilling rig comes from the truck engine, the rig setups distribute implement and hydraulic system. ? we can set up the spare electric engine and clutch implement according to client's requirement, so that the rig can work with diesel engine or electric engine. ? we can set up a electric generator (mf) according to clients requirement, which can provide lighting in night. ? we can setup the 7.5kw vacuum pump for water-absorbing systerm,it will be more convenient to absorb water with 6bs or 8bs mud pump. ? we can setup the hydraulic adding pressure implement, so it has a high efficiency when the rig drill on mud rock and weathering formation through using the adding pressure implement. ? the master driving of rig is mechanical, the four jacks and mast are hydraulic operated. distribute box, sewage pump, master driving clutch system are air operated. the assistant pipes have two types: flanged and screw linked. ? the appearance of rig is pretty; it has a high efficiency because of having larger torque; it is suitable for water well, construction, building, bridge foundation, port, dam and so on; it is popular with the domestic and foreign clients. basic technical technical parameter drilling depth(m) 50 150 drilling diameter(mm) 1500 500 speed of turntable(r/min) 122.3;79.5;49.9;28.3;16.7;15.9reverse) torque of turntable(kn.m) 7.4; 11.4;18.3;31.9;54.1;56.8 (reverse) single rope lifting capacity of main windlass(kn) 30 the capacity of main windlass(kn) 180 single rope lifting capacity of hydraulic windlass(kn) 40 the capacity of hydraulic windlass(kn) 160 lifting capacity of hook(kn) 180 bearing capacity of mast (kn) 200 the height of mast (mm) 9543 pipe kelly bar(mm) 182*182*5000 assistant pipe(mm) ?168*8*3000(screwed connection) hydraulic pump model cb-hp50/32 pump delivery(ml/r) 50/32 rated speed (r/min) 2000 rated pressure (mpa) 20 mud pump flux (m³/h) 200 suction (m) 7.5 delivery lift (m) 26 speed (r/min) 1450 power (kw) 30 sewage pump 6bs sewage pump flux (m³/h) 280 suction (m) 7.5 delivery lift(m) 18 sp
