Mechanical (Hydraulic) Rotary Torque Systems

Delivers reliable torque measurements for rigs that use chain-driven rotary tables Available in box-mount or panel-mount configurations, the RIGCHINA Hydraulic Rotary Torque System provides accurate indications of changes in torque for rigs that use chain-driven rotary tables. Each system includes an Idler assembly and a Gauge. Torque sensor measures torque variation of the drilling tool driven by the rotary table with rotary table torque sensor of tension pulley type, so as to show the operating condition of the downhole drilling tool and changes in the bottom hole stratum, which is helpful to know the downhole condition and avoid accident. Technical Specification: 1. Output hydraulic pressure signal range: 0 6MPa 2. Tension pulley external diameter: F305mm 3. High-pressure cylinder diameter: F65mm 4. Minimum height of sensor: 355.5mm 5. Operating temperature: -40. +85 ºC 6. Non-linear error: 0.5% Features: 6-inch fluid-filled Gauge Available in 500 and 1,000 points Gauge has operator-adjustable dial to zero out drill string in order to monitor torque at the bit Standard 25-foot hose, with other hose lengths available Rugged Steel Sprocket available (replaces rubber wheel located in Idler assembly) Benefits: Gauge damper minimizes pointer oscillations caused by drilling and drill string vibration, ensuring accurate readings and increasing the life-span of the gauge. Helps driller know when to change drill bits by indicating hole conditions and torque patterns. Increases safety and optimizes drilling efficiency by providing warnings about possible twist-offs, locked cones on the bit, out-of-gauge holes, and formation changes. Connects easily to RIGCHINA drilling recorders to track and record trends. To order specify: Bracket-mount or panel-mount gauge Gauge capacity Chain size Chain width (single or double) Hose length (25 feet is standard)
