Obverse-reverse circulation construction and water well drilling rig (BZCF350ZY)

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 client’s 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.
