Torsional shear electric wrench prices, in general science and technology (certified), torsional shear electric wrench provided by S & P Technology Co., Ltd. Jinan. Jinan Cape Technology Co. (www.jnddbs.cn) is specialized in the "strong type torsional shear electric wrench, torque electric wrench torsional shear electric wrench tight end early, twisting" of the enterprise, the company of "honesty, hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Liu. Mainly used in steel electric wrench installation industry, specifically the installation of high-strength steel bolts, high strength bolts are used to connect steel contacts, usually occurs by way of the bolt group. High strength and torsional shear bolt can be divided into two kinds and large hexagon, GB torsional shear type high strength bolts for the M16, M20, M22, M24 of four, and now there are non-national standard M27, M30 two kinds; GB large hexagon high-strength bolts for M16 , M20, M22, M24, M27, M30 and other types. General high-strength bolts for fastening must first tight end early and then tight torsional shear electric wrench, and every step we need to have strict torque requirements. Early high strength large hexagon bolts tight and tight end must use a torque wrench set. Electric torque wrench set to use: set torque electric wrench can be either tight end tight early, and its use is to adjust the torque, then tighten bolts. 1, the power supply voltage should be preceded view is consistent with the product nameplate, whether grounding device. When the supply voltage exceeds + 10% voltage steps should be taken, otherwise it will affect the control accuracy. Bad ground easily cause an accident. 2, the ambient temperature of the tools used to install steel -10 ℃ -40 ℃ torsional shear electric wrench, too low will affect the control accuracy. 3. Tighten the bolts are not greater than the initial torque tools, 70% of the rated torque. After the rated torque is not heavy bolt screwed. 4, the tool is used when removing the bolts Jinan torsional shear electric wrench, torque is not greater than its rated torque value. Under normal circumstances, this is not a wrench to tighten a bolt or severe corrosion, should not use this wrench to remove the torsional shear electric wrench quotes, avoid tool damage. 5, when changing the direction of rotation must be carried out until the motor stops after forbidden reverse toggle switch in the operation. 6, when the wrench to loosen the automatic stop switch (if constantly open switch, over five seconds wrench will start their own) to be 4-5 seconds before conducting the start wrench, wrench otherwise not start.
