NKYJZ-1000E 5000NM 1000KN Computer Controlled High Strength Torque -Tension Bolt Test Machine

I. Equipment Overview and Technical Parameters

1.1 Main Purpose: This testing instrument is designed and manufactured in accordance with common national and industry standards for testing machines, such as GB/T 2611-2007 "General Technical Requirements for Testing Machines," JB/T 9370-2015 "Technical Conditions for Torsion Testing Machines," and JJG 139-2014 "Verification Regulation of Testing Machines." It also refers to standards such as GB/T 1231-2006 "Technical Conditions for High-Strength Bolts and Nuts for Steel Structures," GB/T 16823.1-2010 "Fasteners - Torque/Clamp Force Testing," GB50205-2001 "Code for Acceptance of Construction Quality of Steel Structures," GB/T 32076.2-2015 "Connection Assemblies for Preload High-Strength Bolted Structural Connections," EN 14399.2-2005 "High-Strength Structural Bolting Assemblies for Preloading - Part 2: Suitability Test for Preloading," ASTM A325M-2009 "Standard Specification for Structural Bolts, Steel, Heat Treated, 830 MPa Minimum Tensile Strength (Metric)," ASTM F3125/F3125M-15a "Standard Specification for High-Strength Structural Bolts, Steel and Alloy Steel, Heat Treated, 120 ksi (830 MPa) and 150 ksi (1040 MPa) Minimum Tensile Strength, Inch and Metric Dimensions," AS/NZS1252:1996 "High-Strength Bolts with Associated Nuts and Washers for Structural Engineering," and NB/T 31082-2016 "High-Strength Bolt Connection Assemblies for Wind Turbine Towers." It is capable of testing the axial force, torque, and torque coefficient of high-strength bolt connection assemblies with hex heads and double heads, displaying and printing the results. When the axial force reaches the standard value, the device emits a beep and records the peak value of the test data. After a 1-second pause, the device automatically reverses to release the sample. The device automatically calculates and displays the torque coefficient based on the detected axial force and torque. After completing a set of tests, the device automatically calculates the average axial force, average torque, average torque coefficient, standard deviation, and coefficient of variation for the number of samples.
