Drilling rig is the world, a large open pit equipment widely used and efficient perforated. Rig is the early 1980s developed the world's advanced level of the rig. Its lifting pressure mechanism known as the main body, is the heart of the drilling rig, rig lifting mechanism, is the heart of drilling rig, improve the rig, pressure, walking by the agency to perform. Currently, mining drilling rig with no forward chain pressure rig development, chainless pressurized main mechanism to enhance the development direction of the project has become one of the rig. American BE company back in the late 1980s on the development of a chainless pressure drilling rig, this rig has a simple operation and maintenance, safe and reliable operation, removing the altitude maintenance operations, failure rate, and high drilling efficiency, in by widespread international attention, and has been promoted and applied. Domestic drilling rig main mechanism of floating and suspended gearbox structure, equipped with the agency on a DC motor, the deceleration level gear, closed by lifting the pressure spindle drive chain Weihai crawler drilling rig manufacturer, by the rotation of the car Large car driven sprocket drive rapid increase or decrease; in addition Weihai track drilling rig manufacturer, the main mechanism is also equipped with a hydraulic motor to another power source, through the triple reduction (where the last stage and enhance shared) transmitting power to enhance the pressure on the spindle, the turning car driven chain closed Slow promote the realization of large pressurized drilling pressure. Rig plate valve and the throttle plate valve common sense: a valve plate along the direction perpendicular to the centerline channel moves straight closure member, only cut off from the channel and open channels in the valve plate is fully open and fully closed only two location. Special Note: Valve ban valve plate is half open half closed state job. Throttle: the axis of the valve plate is rotatable shaft of the closing member, i.e. the regulating fluid throttling area, and close action of the fluid. Hand wheel counterclockwise to open, clockwise rotation is off, the front adjustable throttle plate installation should check for loose flange nuts, and check the two flanges of the end distance, it should meet the standard requirements. Check valve: check valve is a mounting self-cleaning check valve used in a horizontal pipeline, the installation, the valve to the fluid flow direction arrow Weihai crawler drilling rig manufacturer, should ensure bonnet nut bolt tie Weihai tight track drilling rig manufacturer, after installation, hydraulic pressure is applied by the arrow pointing to prove its flow. In use, a single flow valve without tube can be removed from the high-voltage routine cleaning, maintenance, need to separate the valve and the pressure in the high pressure line. Weihai crawler drilling rig, crawler drilling rig production line, provided by the Luoyang Prius Prius Drilling Equipment Co., Ltd. Road Zhiyuan, temper forward. Luoyang Prius Drilling Equipment Co., Ltd. (www.zuanji888.com/) aims to become and you win symbiosis, strategic partners to move forward, more determined to become the most influential industry-specific equipment business, and you leap together to success !
