Method of use torque wrench calibrators

A. in the use of the torque wrench calibrators, first of all, according to the requirement of the measurement of workpiece, selecting moderate range torque wrench, torque values measured is less than twenty percent of the torsion device in use range, should not be too great A range for small torsion part of reinforcement, small range of torsion is less can outrange that;

B. when using hydraulic bolt tensioning equipment, wrench square tenon connection first good auxiliary accessories (e.g., sleeve, all kinds of batch of mouth), ensure that the connection has no problem. Before strengthening torsion, set need reinforcement force value, and lock the lock device, adjust direction switch knob to the strength of the direction, then when use fast for 5 to 6 times in a row, first make a wrench on the internal components special lubricant can sufficient lubrication, make more accurate torque wrench, durable use.

C. measurement, hand to grasp the handle range, along the direction perpendicular to the torque wrench shell, strength slowly, until they hear the sound of the torque wrench issued a "tower", the torque wrench has reaches the preset torque value, the artifact has strength, and then immediately lift 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;

D. in order not to make the deviation of measurement results for the horizontal and vertical direction and effect, when measuring 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.

E. the reading of the torque wrench: if it is with table torsion instrument, directly read pointer indicated data to measure value; Sleeving and if it is a dial indicator, should first read the scale value on the scale, scale and vice or differential cylinder on the scale value to measure the sum of the data values.

F. torque wrench is a measuring tool, to should take put down gently, not a substitute for hammer knock, need not when please note set to the minimum torque, stored in a dry place. Torque wrench has a wide application scope, the reinforcement force, was relatively simple, only need to set the required torque value can operate

hydraulic torque wrench chart application:

hydraulic torque wrench chart is the fastening bolts, high-strength bolts can be classified into sets of torshear type and two types: large Hexagon, national standard sets of torshear type high strength bolt M16, M20, M22, M24, four, now also has non-GB M27, M30, two;GB large Hexagon bolt M16, M20, M22, M24, M27, M30, and so on.First for hydraulic torque wrench manufacturers bolt fastening tightening final tightening, and each step requires a stringent torque requirements.Beginning of big hexagonal high-strength bolts tight and tight end must use a torque wrench.

Solve the torque wrench

① the right setting calibration of torque wrenches setting values.When the set torque wrench set value, should take fully into account the parts of interaction between the components of the Assembly process, parts flying and ground force change parts material caused by different final torque changes, the actual situation, to set a reasonable value.Set the torque wrench setting value is mainly as follows:

② for mechanical flange spreaders mutation, drift, can develop a reasonable calibration cycle, find such inaccurate torque wrench, repaired, adjusted to avoid inaccurate torque wrench into the production site.Some change is great, easy alignment of torque wrenches to take every day check or get the metering Chamber repair solutions, ensuring the accuracy of the torque wrench.Wuling company through torque wrench 2 times per week every week, week school pass rate from the lowest to the highest 50% of 100% and stable 95% above."We must first sharpen his tools", we know the torque monitor the quality of the entire process, to improve quality control of torque, also needs to improve the quality of the tools such as SPC (statistical process control), the PDCA (plan-do-check-Act).By repeatedly implemented, torque quality will achieve the desired objectives.

the definition of Torque wrench

dial indicating torque wrenches also known as Torque Wrenches, torque wrench or torque wrench, is a kind of wrench, generally divided into two types of torque wrenches and hand torque wrench.Low Profile Hydraulic Torque Wrench is the product of force and distance, when fastening screws threaded fasteners such as bolts and nuts need to control the torque exerted, to ensure that the threaded fastening torque havoc from a thread, so use a torque wrench to operate.First, set a maximum torque required, when the applied torque reaches the set value, the wrench will issue a "Kata" sound or wrench connection bend angle, which representatives have been tightened to stop afterburner.

Torque wrench with maintenance, maintenance

hydraulic torque wrench chart after using for a long time, because the working environment is not ideal, dust, moisture and other internal parts sedimentation causes a torque wrench, calibration of torque wrenches use frequently wear of internal parts, causing a torque wrench indication of instability.Thus, regular maintenance torque wrench, torque wrench for operation is helpful.

The selection of torque wrenches

1. use dial indicating torque wrenches to take into account the following factors
Torque wrench selection should be based on the torque value, set the torque value should be kept to a torque wrench
Use 1/2~2/3.
Space in the context of the effective length of the high strength bolt torque coefficient calibrator.
Meet above 2 points of, should selection weight light of torque wrench, reduced workers of intensity for example: now has a operation space sufficient of station need using set value for 80Nm of set value type ratchet head torque wrench, from East daily with torque wrench information (see schedule) in the, we see can with have torque wrench has QSP100N, and QSP140N, and QSP200N 3 species, which QSP140N, it than QSP100N long, set value in using range of 1/2~2/ 3, weight lighter than QSP200N.Which should ideally be QSP140N

Flange connections

Flange connection is to two pipes or pipe pieces of equipment, each first end fixed to the top flange, the flange gasket between the two flanges together, bolted together, fixed. Some pipes or fittings equipment, already comes with flange, it also belongs to the flange connection.

 This connection is mainly used for non-ferrous metal pipes and flanges valves, cast iron pipes, rubber lined pipe connections, process equipment and flange connections also flange connection, the main advantage is the easy removal of the flange connection, high strength, density good, but must pay attention to the mounting flange must take to maintain a balance on both sides of the flange, flange sealing surface can not have a bump, where the manufacturer must also be noted that during transport flange sealing surface can not have a bump, and When you install must be clean, flange gaskets used to design requirements and more choice, can not be used indiscriminately.

Flanged connections are important to the main pipe fittings equipment construction time.

 Flange connection flange with threaded connection (including threaded flange, which is connected to the flange wire), as well as welding flanges. High pressure and large diameter flange welded flange connection mode, low pressure small diameter flange threaded flange connection mode, flange different caliber, different pressures flange, flange thickness and bolt diameter and the number of connections is different. Depending on the pressure flange, flange gasket there are different materials, there is a low pressure asbestos pads, high pressure asbestos pads, as well as metal asbestos mats, in accordance with the flange pressure rating procurement asbestos pad.

Flanged pipe fittings in construction and easy to use when disassembling, able to withstand greater pressure in the industrial pipe fittings equipment installation, flange connection is very common, is widely used in the family may not see the flange connection, if a boiler room or production site, everywhere flanged pipe and equipment connections.

Flange connections can now be said to be very common, as long as the construction site, there flange connection, flange connection is very easy to install, simple to operate, but also easy to disassemble.

How to properly regulate the fastening flange bolts

First, as ready fastening flanges need to use tools including wrenches (wrenches and adjustable wrench) bolts, flanges and other related tools

Next, as shown in the bolts had to be put away tight gasket, and then another flange smooth on top, each one bolt hole to be aligned. Do not place the note after a smooth touch flange.

Next, the most important is when the bolt according to the angle, the first hand hold the bolt diagonal, until the flange can not shake up, note that at this time to guarantee the correctness of the position of the gasket.

Then, tighten the bolts with a wrench vigorously, until it stops, then the note is facing tight angle, while tight look, or the other side will tilt.

Then, another bolt also installed on the diagonal, the same is also a tight angle, while tight look, head to prevent warping.

Finally, all the bolts are eleven strengthened by diagonal sequence tighten again to prevent loosening, after adding other connections to such protection does not leak fastening flanges.

Something about flange

Flange, also known as flanges or flange flange. Flanges are interconnected between the tube and pipe parts for the connection between the pipe ends; import and export are also useful in the device on the flange for connection between the two devices, such as the reducer flange. Flange connection or flange joints, is defined by the flanges, gaskets and bolts of the three interconnected as a combination of a set of detachable connection seal structure. Pipe flange means plumbing fixtures in piping flanges, with import and export flange on the equipment means equipment. There are holes on the flange, so that the two flange bolts tightly connected. Between the flange sealing gasket. Threaded flange connection points (threaded connection) flanges, welded flanges and flange clip. Flanges are used in pairs, low-pressure pipe flange can be connected using wire, four kilograms more than the pressure of the use of welding flanges. Between the two flange gaskets, and then secured with bolts. Different flange thickness at different pressures, the bolts are used is also different. Pumps and valves, and pipe connections when local these facilities and equipment, but also made the corresponding flange shape, also known as the flange connection. Any use of the two planes simultaneously closed around the bolted connection components, generally known as the "flange", such as connecting ventilation ducts, this type of parts can be called "flange parts." But this is only a partial connection devices, such as flanges and pump connections, bad water pump called "flange parts." Relatively small, such as valves, etc., can be called "flange parts."
