hydraulic torque wrench chart

hydraulic torque wrench chart is also called the torque wrench, torque is the product of the force and distance, when the thread fasteners such as fastening screw bolt and nut torque size needs to be controlled, to ensure that the thread fastening and not because of destruction of the torque is too large, so use the torque wrench to operate. First set a maximum torque, torque reaches the set value when, wrench "card tower" noise or wrench joint bending Angle, this is already tightening torque. Torque wrench can be divided into: preset torque wrench, torque wrench calibration tool, MINI type torque wrench, torque wrench, dial torque wrench set value.

torque wrench calibration tool

When the piston torque wrench calibration tool work, and generally is in the 10-32MPa State, and pressure flow is high pressure (32-70MPa) flow rate 2.2 times, integrated three-level pressure and flow curves, three-stage flow speed is the secondary flow of the pump pump nearly twice times.Three-level torque wrench calibrators pumping speed is much faster than the secondary pump.

Electro-hydraulic wrench consists of brushless motor and pump motor carbon brush motors.Brushless motors are usually induction motors, need a capacitor.In order to pump to start with pressure, need to install the start capacitor running capacitor.Brush motor is series motors, high speed, can provide a larger pump flow, but more noise and vibration.
Brushless motors are often used for tens of thousands of hours, brush motor life and hundreds of more than more than 1000 hours of continuous operation, reach the limit you need to replace the carbon brushes, or is likely to cause bearing wear.

Characteristics of hydraulic bolt tensioners

Using ultra hydraulic bolt tensioners strength light metal, thin design, double-acting, high-speed, large turning angle
Card-Exchange plugin, do not need special tools, torque repeatability up to ± 3%
360 ° x360 ° and 180 ° X360 ° rotating hose connectors, suitable for compact and convenient locationtorque wrench calibration tool strength design, the overall reaction arm, less moving parts, durable, reliable
Scalable metric, Hexagon Plug and socket, can achieve a power head is equipped with multiple plugins using
Most were used for special working conditions: double nuts, bolts and equipment too close to the wall, spacing is too small for long bolts, nuts, and more!
