A complete hydraulic tool system consists of five parts, namely power components, actuators, control components, auxiliary components and hydraulic oil.

Hydraulic tools include hydraulic crimping tools, hydraulic pumps, hydraulic jacks, hydraulic bolt tensioners, hydraulic flange separators, hydraulic nut breakers, hydraulic pullers, etc. Hydraulic tools have the advantages of high efficiency and convenience.

The working principle of hydraulic tools is Pascal’s principle, also known as the principle of static pressure transmission. The pressure applied to any part of the liquid in a closed state will be transmitted in all directions according to its original size. Hydraulic tools use this principle to transmit the pressure applied to the static liquid to all points at the same time, so as to realize the extraction of heavy objects, forging, and other work. Hydraulic tools are easy to use, easy to operate, have a long service life, and can realize machine automation, but they also have disadvantages such as easy leakage, inaccurate transmission ratio, and high manufacturing costs. In general, it is a more convenient tool to use.

Follow the steps below to properly use hydraulic tools.

1. First, select the matching crimping die according to the wire diameter of the cable, and loosen the pressure relief valve, generally measured on the right.

2. After stripping the insulation layer of the cable according to the length of the copper (aluminum) tube, put the copper (aluminum) tube on the core wire with the insulation layer removed.

3. Put the hydraulic pliers of the selected crimping die on the end of the copper (aluminum) nozzle without the wiring nose, tighten the release switch, put the crimping die outside, and then start crimping, crimping to the two crimping dies touch, and then release the pressure. Continue to crimp next to the crimped place, generally crimp 4~5 places, this depends on the quality of your copper (aluminum) nozzle.

4. After the crimping is completed, use pliers or a flat file to remove the burrs produced by the crimping, polish it smoothly, and do a good job of insulating treatment.
