800-2000N. m electric torque wrench/torque electric wrench
Find an electric torque wrench and come to a Shanghai foundry for my SGDD series 800-2000N. m electric torque wrenchtorque wrenchEquipped with automatic torque control function. its800-2000N. mElectric torque wrenchIt is a mechanized construction tool for assembling threaded parts and bolts.
This elbow electric torque wrench is used for the installation of bolted welded structural bridges, as well as for the installation of factories, towers, and chemical, metallurgical, and power generation equipment. My elbow electric torque wrench is also used in large machinery, lifting equipment, and vehicle assembly operations, as well as in situations where there are strict requirements for torque and axial tension of threaded fasteners.

Characteristics of electric torque wrench:
This elbowElectric torque wrenchIt consists of two parts: the host and the controller. The host adopts a dual edge single-phase series excited motor and a reduction mechanism, with a novel structure, small size, and light weight. Due to the use of a static torsion structure, the operation is smooth, without vibration or impact, with low noise, and the operator is not affected by reverse torque, resulting in low labor intensity. Rated voltage 220V50/60Hz with an accuracy of ± 5%.

Selection and adjustment of torque for elbow electric torque wrench
1. Users can freely choose the corresponding specifications within the range of 50-3500N. mRechargeable elbow electric torque wrench.
2. There is a "torque adjustment knob" on the control panel. It is engraved with 0-10 scale values. The function of the fine adjustment knob is to adjust and compensate between the coarse adjustment and coarse adjustment, in order to control the accuracy of torque. (See next page)
3. Adjustment method: Chinese products come with torque test data cards at the factory for users to refer to during calibration. Users can select a certain scale value based on the required torque, tighten the bolt according to the operation method, and measure the actual torque value of the bolt with a force wrench or other force measuring instrument. If the torque difference is small, fine adjustment can be used to compensate. If the difference is large, coarse adjustment can be adjusted up or down by one gear, and repeated several times to obtain the required torque value.

Precautions for operating electric torque wrench
(Special attention should be paid)
1. Before connecting the power supply, check whether the power supply voltage matches the nameplate of the domestic product and whether there is a grounding device. When the power supply voltage exceeds+10%, voltage stabilization measures should be taken, otherwise it will affect the control accuracy. Poor grounding can easily cause accidents.

Introduction to SGNJ Twist Shear Electric Wrench:
The SGNJ torque shear electric wrench I produce only needs to replace the inner and outer sleeves to be suitable for the construction operation of M16-M30 torque shear bolts produced by various manufacturers. This machine uses special steel and special heat treatment technology, and there is no rebound during operation.

SGNJ twist shear electric wrench features:
1. High speed motor, low noise, high power, rated voltage 220V50/60Hz;
2. Edge engineering material shell, double edge, sturdy;
3. Gun style grip, ergonomic load, increased grip, reduced fatigue strength;
5. Precise planetary deceleration, efficiency, and smooth operation;
2. The environmental temperature for tool use is -10 ℃ -40 ℃, and both high and low temperatures can affect control accuracy.
3. The initial torque of the tightened bolt shall not exceed 70% of the rated torque of the tool. After the bolt reaches the rated torque, it shall not be re tightened.
4. When the tool is used to disassemble bolts, its torque must not exceed the rated torque value. Generally, bolts that are not tightened with this wrench or severely corroded should not be disassembled with this wrench to avoid tool damage.
5. When changing the direction of rotation, it must be done after the motor has stopped rotating, and it is strictly prohibited to toggle the positive and negative switches during operation.
6. After the wrench stops automatically, the switch can be released (if the switch is not turned on, the wrench will start automatically after 5 seconds). Wait for 4-5 seconds before starting the wrench, otherwise the wrench cannot start.
