1. General
The water well drilling rig model WS300TRM ( Fig.1), is a trailer mounted rig for rotary drilling, with all its components are mounted on the trailer . The rig is mechanically driven with on part of its operating mechanism being hydraulic and the other part being mechanical.
In addition to the main operating made of rotary drilling by rotary table.. For rotary drilling, mud is used as flushing fluid (positive cycle). Moreover, the two—arms drilling tool is equipped as air lifting reverse cycle; The shallow—bore hammer tool, air compressor and speed reducer of increasing rotary table are equipped as foam drilling, Auger tool is equipped as Auger drilling.
At the beginning of boring, pressuring mechanism may be used for drill tool to effect pressuring drilling, thus promoting the efficiency of shallow hole drilling. With the increased depth, when the weight of the drill tool is greater than the pressure required to apply to the drill tool, the main hoisting system should be used to carry out reduced—pressure drilling.
The drilling rig is provided with one main hoist and tow secondary hoists.
The main hoist is used for lifting or lowering of the drill tool, lowering of the well pipe, reduced-pressure drilling and percussive drilling.
One of the secondary hoists is used for driving percussive earth excavator or other coring tool and sand reel to extract sand sample or core and silt in the well. The other secondary hoist is used for elevating the movable table.
The drilling rig are equipped four jacks to reduce physical labour and improve install efficiency.
The drilling rig isn’t used the truck engine. It is separately equipped diesel engine (The buyer can choose model 6135AN or F6L912 or BF6L913 etc diesel engine).
2. Main Characteristics and Applications
This drilling rig features in best maneuver ability, compact construction, high.
integrity, economical transportation, and simple operation, Reliable transmission, high versatility and efficiency. After loosening the first turn of thread of the lock joint with the aid of breakout-gun cylinder, the drill pipe can be rotated in clockwise or counter-clockwise direction by the rotary table to reduce greatly the labour intensity and prolong service life of the component parts.
In order to improve efficiency of drilling, This drilling rig is equipped with related drilling tool that can be applied various advanced drilling technology.
The drilling rig may be used for drilling in quaternary period stratum and matrix water well. Rotary drilling can be made right with a depth of 300m. And bore diameter of 500mm.
