SZJ-ZN System composition and working principle:

Measuring unit of mechanical drilling rigs (driven by rotary chain) consists of idler rotary torque

sensor (Figure 1-1), rotary torque gauge (installed in the driller’s console), damper valve,

connecting hose, and etc. Rotary torque measuring unit obtains rotary torque indirectly by testing pull force of tight side of rotary drive chains. Install rotary torque sensor under tight side of drive chains.

The pressure is transmitted to the bourdon tube of rotary torque gauge via hose of hydraulic system, and the free end of the tube thus begins to

move, which in turn drives the pointer to deflect by an amplifying mechanism to indicate rotary torque. Connection parts of sensor are shown hereunder:

Two rotary torque sensors of the same type can be installed for the measurement of torque rotating in clockwise and anti-clockwise directions. Users can choose to use one gauge or two gauges. When there is only one gauge, the operator has to switch between two sensors manually. What’s app +8615972752793 Luben@youlongpetro.com

The key point for the use of the idler sensor is that there must be enough space in the chain box for installation and meet the requirements of the sensor ordered (e.g. single or dual chains, 2inches, 1.5inches or 1.75inches, etc.).
