Preservation of our Environment with Tap Water Hydraulics
Oil hydraulics systems have been used in industry for about one century now. Such systems mainly use mineral oil as the pressure medium to transmit power in order to perform work. However, due to indiscriminate dumping of used mineral oil into rivers, sea and ground, as well as leakage into the ground from oil hydraulic systems world wide, the application of oil hydraulic systems is a large source of oil pollution to our environment. This is causing growing concern among developed nations. Consequently, it led to the interest of using tap water as a pressure-transmitting medium after a long search for a suitable replacement for the oil in hydraulic systems. Unfortunately, many industrial personnel today have grown up in a world that has been accustomed to using mineral oil in production machinery and, to them, putting water into these machines is simply unthinkable. This paper aims to educate and inform readers as well as to address their concerns in applying modern tap water hydraulics in their industrial operations. The ultimate objective is to convince the industrial community of the benefits and advantages of using water hydraulics technology and to collectively preserve and protect our environment from being contaminated by hydraulic oil spillages and indiscriminate dumping by users world wide by reducing the use of mineral oil as the pressure medium in hydraulic machinery as much as possible.
