The cautions of the torque wrench calibration tool

The torque wrench calibration tool for high precision products, for this, please note:

1. Do not strongly in the use of impact;

2. Absolutely cannot be used as a hammer, tap on a workpiece;

3. Spanner alarm do not continue to work after;

4. Before use, please check if the arrow on the wrench with power works in the same direction, if not consistent, please install the rotate for 180 degrees to wrench;

5. Please remove the wrench parts, lest destroy the precision influence use;

6. torque wrench testers, after use, should be placed torque value to zero, to keep the wrench precision, prolong service life;

The use of the Square Drive Hydraulic Torque Wrenches

1. Set the Square Drive Hydraulic Torque Wrenches value;

A. the lock handle counterclockwise, loosen the adjusting wheel.

B. turn the adjustment wheel, causes the main scale and vice scale (round adjustment scale) value is equal to the sum of what you need to set torque value.

C. after torsion value setting, spin clockwise to lock tight grip, torque value after work.

2. Spanner Fang Sun set into the corresponding size of the sleeve;

3. The sleeve set into the nut or bolt head;

4. Uniform power works clockwise;

5. When they hear "clicking" sound, or feel wrench has unloading force feeling, I have to set hydraulic torque wrench chart value;

6. When you long screw bolt or tubing type of nut, sleeve, without zai-shallow pits method work at this point, the need to replace a verbal;

A. press positioning pin, along the direction of force applying, wrench head is desirable.

B. will choose corresponding size of the open after oral insert the wrench screw rotation, can make catapults dowel pin holes in a wrench head positioning.

dial indicator torque wrenches

dial indicator torque wrenches has the preset torque value and sound device. Use, first set a maximum torque, torque reaches the set value when, Mechanical Torque Wrenches "tower" noise or wrench joint bending Angle, at the same time companion has apparent handle vibration, it's representatives have tighten don't strength again, prompt to complete the work. After lifting force, wrench the relevant parts can be reset automatically.

The rules for using a Hydraulic Nut Splitters

1. Measurement, hand to grasp the handle range, along the direction perpendicular to the Hydraulic Nut Splitters, strength slowly, until hear the sound of the torque wrench issued a "tower", torque wrench has reaches the preset torque value, artifacts have strength, then we should timely lifting force, so as not to damage the other parts. According to the national standard in the process of applying, instrument operation specification, about its verticality deviation should not be more than 10 degrees. The horizontal deviation shall not be more than 3 degrees from top to bottom, the operator shall guarantee that the up and down or so in the process of use force application scope not more than 15 degrees;

2. In order not to make the deviation of measurement results for the horizontal and vertical direction and effect, when measured, precision torque screwdriver should be applied on the strength of end of a vertical downward strength, stability and then manually add some force, such use value more accurate.

dial indicator torque wrenches matters needing attention

dial indicator torque wrenches for high precision products, for this, please note:

1. Do not strongly in the use of impact;

2. Absolutely cannot be used as a hammer, tap on a workpiece;

3. Spanner alarm do not continue to work after;

4. Before use, please check if the arrow on the wrench with power works in the same direction, if not consistent, please install the rotate for 180 degrees to Mechanical Torque Wrenches;

5. Please remove the wrench parts, lest destroy the precision influence use;

6. Preset torque wrench, after use, should be placed torque value to zero, to keep the wrench precision, prolong service life;

The use of the precision torque screwdriver

1. Set the required precision torque screwdriver:

The required torque can be set through the shaft tube on the scale, the zero graduation of labelled vice ring at the center of the cylinder and then clockwise rotation axis cylinder, in order to increase the reading, reach the required torque value, stop.

2. The flange alignment tool correctly using:

Preset torque screwdriver after setting can be through the adapter connected to all kinds of fasteners, clockwise turn, fastening torque measurement. Turn clockwise to fastening torque measurement. When reach the set value from "click, click, click..." The sound. Preset torque screwdriver once set can be used repeatedly under the same value, until it is need to set another torque value.

One-piece hydraulic flange spreader

hydraulic flange spreader is put 15 tons, it - 150 - d maximum separation is put 2 * 15 tons

Low minimum separation clearance only 6 mm

The measure of the separation of low of 65 mm

Low radius 150 mm arc steps can effectively further close to the flange, make each step can bear larger load

Forged alloy steel separation step, longer life

Low light reinforced plastic handle design, easy to carry

Low within the unique lock structure to ensure the Hydraulic Nut Splitters of pressed flange, when I opened and not excessive expansion, automatically return when closed

Tubing unibody design, no connection, it is more convenient to use

The benefits of hydraulic flange spreaders

1, hydraulic flange spreaders, single operation, apply to narrow space and aerial work

2, portable, reduce the labor intensity, wide applicable scope

3, wide applicable range, convenient, safety and efficiency

4, electromagnetic valve electric pumps improve the service life

5, expand the scope of use, to prevent damage the flange gasket
