Square
Drive Hydraulic Torque Wrench
The calibrated
hydraulic torque wrench can measure the torque applied to tighten, loosen, or
achieve the desired tightness of a bolt. In 1968, George A. Sturtevant created
it. Since then, a variety of industries; including transportation, field construction,
and oil and gas exploration, utilizes them. On fasteners or bolts that are
well-lubricated, hydraulic torque wrenches are used. Compared to pneumatic
torque wrenches; hydraulic torque wrenches are lighter and operate quietly.
These wrenches can be used for a long time and are extremely accurate to +3%..They
can be square drive or low character. The intended application area determines
the design of each of these. Newton meters, or pound feet, are the units of
measurement for the force-distance product. The way a hydraulic wrench works is
what sets it apart from other powered wrenches. These wrenches only use
hydraulic pressure to generate torque.
How It Works
To
understand how the hydraulic torque wrench works, it is important to keep in
mind the fact that its working principle is based on Newton’s Law that for
every force applied, there is an equal and opposite reactive force. When the
wrench is placed on a nut or bolt and turned, there is a tension in the
opposite direction that acts as the clamping force pulling the bolted
components in the same direction with a definite tension or load. As the torque
increases, the joint integrity gives way to loosen or fasten the bolt. The
amount of torque needed to fasten or loosed depends on the length, size and
type of joint, quality of the fastener and the lubricant used in it.Hydraulic
torque wrenches are designed to fit different height and width of joints and
their respective nuts. This offers easy and free movement without interference
of surrounding parts.
1. A
hydraulic stud bolt tensioner or a hydraulic tensioning device exerts force on
the bolt.
2. The
high-pressure hydraulic cylinder and accessories used to fasten the grip are
the components of this device.
3. The
applied measured hydraulic pressure reaches the cylinder piston and presses it
against the puller, which in turn pulls or stretches the bolt.
4. The
bolt is run down tightened against the joint whenever the applied force exceeds
the preload tension and relaxation force of the bolt.
5. In
the subsequent step, the tightened nut releases hydraulic pressure, preventing
the fastener from returning to its original position.
6. The
reaction member of a hydraulic torque wrench is the component that poses the
greatest risk. • The applied tension is measured in kN.It blocks the wrench
from turning the fastener around because it rubs up against the stationary
object.
When
is this tool needed?
The Square Drive
Hydraulic Torque Wrench is the ideal tool to perform torque tightening on bolts
with an accuracy of +/- 3%. The NS Series withstands even the toughest tests.
It is a tool able to cope with those applications which require intense use and
for long durations. It is a made in USA product, composed of a special
extremely resistant aluminum alloy. In order to be used it needs square drive
bushes, which are supplied separately.

How
are the hydraulic wrenches powered?
The hydraulic torque
wrenches are powered by two types of power units, namely by electric power
units and pneumatic power units.
Why
should we choose Square drive hydraulic torque wrench
Heavy-duty
bolting jobs call for hydraulic torque wrenches.
A hydraulic torque
wrench is the best choice if you need a torque wrench with enough power for
heavy-duty applications. Because hydraulic torque wrenches only use hydraulics
to generate torque, users need not exert much effort to tighten bolts to a
certain torque. Heavy-duty industrial tasks like flange bolting call for
hydraulic torque wrenches. They have gotten better over time and new versions
have come out, so it is now possible to buy and use lighter versions with
smaller nose-radii for easier access.
Self-ratcheting and
accurate, hydraulic torque wrenches hydraulic torque wrenches offer a high
level of accuracy. In comparison to conventional impact wrenches or manual
torque wrenches, they are made to be all-around simpler to use. They performed
in accordance with health and safety standards as well as the requirements of
product designers. We are all aware that under torquing and over torquing can
be disastrous and dangerous.
The fundamental
advantages of hydraulic torque wrenches include: reduced bolting time; improved
joint integrity; saved time and money by avoiding repeated bolting and failing
pressure tests; and more time for other
activities.
