Special bolt detector for wind power industry (high-strength bolts)

The special high-strength bolt tester for the wind power industry is mainly used for testing large-sized bolts in the wind power industry. It can detect, display and print the fastening axial force, fastening torque, torque coefficient, fastening angle, total friction coefficient, thread friction coefficient, and support surface friction coefficient of large hexagonal head high-strength bolt connection pairs (M33-M64).After a set of tests is completed, the detector automatically calculates the average axial force, average torque, average torque coefficient, standard deviation and coefficient of variation of N specimens.This equipment is mainly used for the detection of large steel structures and large wind power bolts!

The tester refers to GB/T32076.7-2015 "Preloaded high-strength bolted structural connection pairs - Part 7: M39~M64 large hexagonal head bolts and nut connection pairs", GB/T1231-2006 "Technical conditions for high-strength large hexagonal head bolts, large hexagonal nuts and washers for steel structures", GB/T 16823.3-2010 "Fastener Torque-Clamping Force Test", ISO16047-2013 "Fasteners. Torque/Clamping Force Test", GBT16823.2-1997 "General Rules for Fastening Threaded Fasteners", GB/T50205 "Construction Quality Acceptance Regulations for Steel Structure Engineering", NB/T31082-2016 "High Strength Bolt Connections for Wind Turbine Towers", GB/T3098.1-2010 "FasteningDesigned and manufactured according to relevant requirements such as "Mechanical Properties of Fasteners Bolts, Screws and Studs", GB50205-2001 "Code for Acceptance of Construction Quality of Steel Structure Engineering" and other relevant requirements. It can detect, display and print the fastening axial force, fastening torque, torque coefficient, fastening angle, total friction coefficient, thread friction coefficient, and supporting surface friction coefficient of the large hexagon head high-strength bolt connection pair (M33-M64).

Structural features: Both the axial force sensor and torque sensor of this equipment adopt a direct measurement structure. This structure can well avoid various errors caused by indirect structure transmission, and the indication value is more accurate.
