Hydraulic torque wrenches are designed like a full power tool to tighten or loosen fasteners, requiring a lot of force to achieve the whole preload. In contrast to hydraulic tensioning devices, which directly stretch a bolt, these wrenches apply a turning force or torque to a nut or bolt head that thread to advance. Now, let’s know more about hydraulic torque wrench types and factions.
Types of hydraulic torque wrench:
There are many types of torque, but here we are going to talk about only two. Your power to fit this device into your application will likely dictate which of you’ll use them.
S series square drive: This drive has a reaction arm mounted to the base, adjusted or replaced per your application. The socket mounted to the drive is also present. Remember to use a socket rated to your torque, not a hand tool socket. The direction of the wrench for loosening and tightening can be adjusted.
W series low-profile: low profile divided into two primary components, the drive or the cassette. Instead of anything using a socket, the cassette can be replaced to accommodate different nut sizes, but you can also use inserts. This point is commonly used as the reaction arm, but other arms can be attached and change the wrench’s direction for tightening and losing flip over the wrench.
Hydraulic torque wrench setting can be done in four-step:
Inspect the equipment: Inspect a hydraulic tool before use. The most common issues can be avoided when checking the pump’s electrical or pneumatic components for damage. Make sure to check everything related to the machine properly, so no issue contains. This setting is helpful for future use, and you can use it without thinking of any internal harm.
Connect the components: The couplers are polarized to prevent connecting to the wrong ports. Set the torque value: Locate the datasheet or calibration sheet for your wrench. Identify your target torque and the corresponding pressure for that torque, for instance, on a 4000-foot pound tool, and you’ll generate about 4,000 foot-pounds at near 10,000 psi.
Test for proper function:
- Hold the advance button several times to ensure the proper function of the wrench.
- Check all functions properly and make sure of it.
- Check all buttons and functions properly and make a trial of t serval times, don’t leave any problem and if you found any problem solved it fastly.
