The Precautions and Preventions with Hydraulic systems

07 April, 2010- Hydraulic systems are quite popular in agriculture sector these days. These machines reduce the mechanical efforts manifold and also provide remote control of various operations. Hydraulic systems are generally used for lifting purposes like plowing, or to change the position of components like combining of header or bulldozer blade. It also helps in assisting the process of steering and braking.

Since the hydraulic machines contain hot high pressure fluids, the worker working closely with the machine is exposed to three hazards, namely, burns due to high pressure fluid, bruises or cuts due to hydraulic line failure and injection of fluid into the skin.

Carelessness with Hydraulic Pinhole Leaks

The most common injury while working with hydraulic systems is the pinhole leaks. Pinhole leaks refer to minute holes in hoses which are almost impossible to locate with naked eye. One can only notice a damp and oily area on the running hose and might as well run a hand or finger on the line to find it, this is precisely when the hydraulic fluid can be injected into the skin just the way through a hypodermic syringe.

This type of injury can only be avoided by using a piece of cardboard or wood rather than finger, along the hose to detect the leaks.

Mismanagement of Pressure Variants

Another major hazard associated with hydraulic systems is the coupling of low-pressure and high-pressure components. The mismanagement of two different pressure variants can cost the rupturing of hose, fitting or components hence, due attention should be paid to it. Pressure relief valves are the ultimate solution for this particular issue. These valves help avoid the pressure buildups and render smoothness to the working of entire system. Though periodical testing and cleanliness of valves have to be ensured.

Maintenance of the Entire Hydraulic System

Maintenance is the key to a long lasting machinery. The general maintenance of hydraulic system includes:

• Recurrent check for oil leaks and worn hoses.
• Replacement of filters and keeping a check of the contaminants in hydraulic oil.
• Avoid cylinder rod rusting by layering it with protective lubricants.
