Prior to deep diving into how hydraulic torque wrench work, let us better understand torque wrenches in general.

Torque wrenches are used to fasten or loosen bolts and screws.

They play an vital role where tightness is a crucial factor. They’re designed to use a measured torque to realize the desired tightness of bolts.

Know Your Hydraulic Torque Wrench

A hydraulic torque wrench is an advanced version of the traditional handheld torque wrench.

A hydraulic torque wrench is a device with calibration that can measure the torque applied to fasten and attain the desired tightness or loosen a bolt. It was invented by George A Sturdevant in 1968. Since then, they are used in a cross-section of industries prominent amongst which are transportation, area erections and oil and gas explorations. Hydraulic torque wrenches are used on well-lubricated bolts or fasteners.

Hydraulic torque wrenches are lightweight and have quiet operations compared to their pneumatic counterparts. These wrenches are highly accurate to the extent of +three% and also have prolonged usability. They are ideal for industries and application where massive bolts are used with high degree of torque accuracy.

Hydraulic torque wrenches could be of two types – sq. drive and low profile. Every of those are designed relying on the specified area the place they are to be used.

Torque is the product of the turning force utilized on a bolt and the distance from the middle of the object twisted to that of the tool. The product of the force and distance is measured in pound ft or Newton meters.

Hydraulic wrench torques are set apart from other powered wrenches because of the way that they operate.

These wrenches produce torque using only hydraulic pressure.

They have a self-ratcheting mechanism

They embrace a system that can measure the torque utilized with precision.

To understand how the hydraulic torque wrench works, it is important to keep in mind the truth that its working precept is based on Newton’s Law that for every force applied, there’s an equal and opposite reactive force. When the wrench is placed on a nut or bolt and turned, there’s a stress in the opposite direction that acts because the clamping force pulling the bolted elements in the same direction with a definite tension or load. As the torque will increase, the joint integrity provides way to loosen or fasten the bolt. The amount of torque needed to fasten or loosed is dependent upon the length, measurement and type of joint, quality of the fastener and the lubricant utilized in it.

Hydraulic torque wrenches are designed to fit completely different height and width of joints and their respective nuts. This presents easy and free movement without interference of surrounding parts.

Force is utilized on the bolt utilizing a hydraulic tensioning gadget or the hydraulic stud bolt tensioner.

This machine consists of a high-pressure hydraulic cylinder and accessories that are suitable with bolt and designed to fasten the grip.

The measured hydraulic pressure that’s utilized, extends to the cylinder piston taking it against the puller that in turn pulls or stretches the bolt.

Once the utilized force exceeds that of the preload stress of the bolt, and that which is needed for its rest, it is run down tightening it against the joint.

Within the next step, hydraulic pressure is launched preventing the fastener from returning to its earlier position by the tightened nut.

The strain that is applied is measured in kN.

The reaction member of a hydraulic torque wrench is its most dangerous part. It abuts in opposition to the stationary object stopping the wrench from turning the fastener around.

Best ways to use the hydraulic torque wrench for optimum results

There are specified ways in which a hydraulic torque wrench have to be used to keep up safety. Like most advanced instruments, hydraulic torque wrenches operate optimally when certain parameters are applied following safety precautions.

Wearing safety gear like gloves and googles are a must when working with a hydraulic torque wrench. It is usually vital that you just wear a coat/apron to offer your self proper cover that will take care of any jewelry or hanging objects.

It is crucial that you run the wrench at the least twice on the highest scale earlier than making use of it. This will enable you decide if the moveable parts are running with their proper motion and within the desired direction.

Any hydraulic torque wrench needs to be firmly held by its handle and never by the hose or aligned connections.

Make sure to keep your hands away from the reaction bar or the boot.

As you apply the torque, use a pulling motion, not pushing.

Do away with all cracked or worn sockets as they might break, damage the nut or end in larger disasters.

Preserve a good distance from the socket and protect your self in case of an accidental break.

Applying pressure that exceeds calibrated range is an absolute no as it not only leads to instrument malfunction however can be likely to result in accidents.

It’s vital to have your hydraulic torque wrench recalibrated no less than once a year. In case of a drop, make certain to recalibrate it earlier than utilizing it again.

Utilizing a cheater bar to leverage your self runs the risk of both damaging the torque wrench and getting incorrect readings.
