Hydraulics are used for many different functions and if you work in an industrial setting or around large machinery, you may have been working with hydraulics and not even known it. Hydraulic systems use pressure and a fluid or oil to move a ram that in turns moves the parts it is attached to. These systems are so common that we take for granted that they will work and are often surprised when they fail.
Uses For Hydraulics
Because of the way these systems work, the ways that hydraulics can be used is extremely flexible. The ram and pumps in some systems are very strong and can lift thousands of pounds in the form of hydraulic jacks, while other uses might be to steer a large tractor, raise the lift gate on a delivery truck, or force the ram on a trash compactor to move and compact the material inside. These are just a couple of ways you may have seen hydraulics used in the everyday world. The sizes of the pumps and the rams can vary from small to extremely large and the power sources can be electric pumps or mechanically driven units that are driving off the engine from the vehicle they are being used in.
Leaking Or Damaged Systems
If you are using a hydraulic system to manipulate an object, the biggest concern is for a closed loop of the system to develop a leak or have a hose or pump failure. The system depends on the pressure to work properly and if there is a leak of any kind, the system will not have the pressure in it to work the way it was intended to. Check the pump, hoses, fitting and rams regularly for any signs of leaking oil and if you find a leak, you need to have it repaired right away.
Who To Call
When you are working with hydraulics, you need to hire a technician that understands the system and has the tools to work on them if there is a problem. In some cases, damaged hoses can be replaced with custom-made replacements but it is not always critical to do so. There are industrial parts companies like RNL Hydraulics Sales & Service that can supply you with premade hoses for some applications. For very large equipment like a road grader, bulldozer, or tractor, you can have a mobile technician come out and make the repairs where the equipment currently is and they will often be able to make or restore a part in the field for you. In any case, working with a qualified tech to ensure that the system is going to work properly is important. You can not take shortcuts when working with hydraulics and expect the system to function as it was designed to.
