Before you start talking about diverse options in the realm of torque wrench, it is crucial to know what this wrench really is. A torque type of wrench helps apply the needed sum of torque on a fastener like a nut or even a bolt to either tighten or even loosen it. Once applying the high worth of torque, these wrenches will need a reaction support that will lock itself at a head-to-head point .
Remember that fastener preferably should be lubricated before even beginning the process. If you stay longer with this post, you will get to know about different types of wrenches. The point is whether wrenches, power socket or other tools; you need to be informed about them to make the best use.
Electric Wrench
Contrary to hydraulic and pneumatic wrenches, an electric wrench does not need a pump or compressed air to simply power them as it is directly linked to a power source such as an electric socket. It offers a correctness of +/- five percent. However, these tools cannot get used in all industries because of the possibility of spark generation that risks its uses in explosive industries such as oil and gas,, petrochemical and mining. The electric wrench also has the difficulty of being heavy, possessing an unbalanced weight and more.
Hydraulic Torque Wrench or HTW
The most common and well-known wrench in the industry is a hydraulic wrench. Powered by hydraulics (oil), it delivers the highest power to weight ratio. It simply means that it offers the hugest range of toque inversely proportional to the overall weight of the tool. It even offers the rightest torque output with +/- three percent of accuracy. Hence , the hydraulic type of wrench offers portability and suppleness of usage. Hydraulic Wrenches are there for you in a square drive (external socket needed) and direct fit (hex) drive type of variants.
As HTW are capable of achieving high torque values, proper placement of the reaction arm turns out to be critical to guarding the housing of the tool from an unjustified external force. Preferably, the reaction must be taken in a plane parallel to the alliance of the bolt. The commonest square drive hydraulic wrenches have the reaction mounted on the cylinder part of the tool. The torque wrenches having the reaction arm mounted on the cylinder at the back have the difficulty of the reaction arm not getting parallel to the axis of the bolt once convenient reaction points are not available. Once there are the reaction arm mounted in the front of tool, coaxial to the square drive offers a three hundred sixty degree plane. This make sure that once the reaction arm gets rotated it will be always going to be paralleled to the axis of the bolt and even offering a stress free cylinder as the response arm is not climbing on cylinder.
Pneumatic Wrench
The pneumatic wrench stays powered by compressed air. Most of the times popular in the automobile industry, it works faster and offers an accuracy of +/- five percent. However, pneumatic instruments need constant high air pressure because of which the tool cannot get operated at massive heights.
Conclusion
To sum up , whether hydraulic torque wrench or any other type of wrench; you need to examine your needs before you make a purchase. Every type of wrench works differently and is for dissimilar need.
