The main source of revenue loss due to machine\u00a0downtime is closely linked to an excess of lubricant\u00a0contamination, be it dust, water, contaminants from the process itself, the use of an incorrect lubricant or a mixture of all of these elements.<\/p>\n

Furthermore, this common condition that affects the lubricating fluid\u00a0can appear at any stage in the oil’s life cycle.<\/strong> It is common to all industrial processes\u00a0or, in other words, it does not distinguish between industries.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

<\/div>

Why can\u00a0oil become contaminated?<\/h2>\n<\/div><\/div><\/div><\/div><\/div>
<\/div><\/div><\/div><\/div>
<\/div>
<\/div><\/div><\/div>

Excess lubricant contamination can have two origins: internal\u00a0and external. There are a\u00a0number of contaminants such as external dust, water or humidity that are generated outside the machine and can cause the lubricating oil to become contaminated.<\/p>\n

Other\u00a0contaminants are of an internal origin, inherent to the functions fulfilled by the lubricating fluid inside the machine, and which cannot be avoided during\u00a0operation. These include degradation products or wear particles that come\u00a0from the machine itself. Even refrigerants\u00a0can cause unwanted contamination.<\/p>\n

Therefore, there are a number of\u00a0processes that can add contaminants that are external to the actual functioning\u00a0of the oil, while other contaminants\u00a0are derived from\u00a0the production process itself.<\/strong><\/p>\n

Internal contamination<\/h3>\n

The industrial process in and of itself is a source of contamination for the lubricant.<\/p>\n

One of the oil\u2019s functions is to clean the work areas in the machinery. In this process, the oil removes impurities that can affect the components of the machinery, but it also drags and transports them to the filters in order to completely eliminate them from the lubrication system. These particles not only get the machinery dirty, but they also enter into circulation throughout the system and can cause an accelerated wear and tear of the components and, as a result, breakdowns.<\/strong><\/p>\n

This is the case, for example, of diesel engines. In addition to wear particles, the oil must also face the soot that is inherently generated during its operation. This is not an external agent that comes from a malfunction, rather it is generated as part of the engine’s own operation.<\/p>\n

In the case of water-cooled equipment,\u00a0they\u00a0can also be a source of contamination,<\/strong> because the water and oil are in very close contact with\u00a0each other in the work area. Contrary to popular belief, water and oil can mix, if\u00a0there is a leak from one compartment to the other. For example, in the paper industry, water contamination is an inherent element of the production process.<\/p>\n

External contamination<\/h3>\n

Machinery located in hostile environments, with a greater amount of dust or moisture, is more susceptible to external contamination. In these cases, any operation performed with the machine, including everything from changing the lubricant or checking its levels and components, to routine maintenance<\/a> tasks, can cause external agents to get into the lubrication system, adding abrasive particles or water that negatively affect the useful life of the oil and the condition of the machinery itself.<\/p>\n

In this regard, the slightest deterioration of the sealing components, such as the poor condition of a joint, can act as the access route for these particles that then have a negative\u00a0impact on the lubricant’s ability to clean.<\/p>\n

Inadequate fillers are another common source of contamination. By introducing the wrong oil, its physicochemical conditions are altered,\u00a0such as its viscosity.\u00a0If the components of the oils are incompatible, they produce chemical reactions that attack the surfaces, generating\u00a0sludge that clogs the machine,\u00a0which in turn leads to a critical failure.<\/p>\n

External contaminants are a common problem\u00a0but, as we’ve\u00a0seen, they are\u00a0no less important.<\/strong> That’s why it’s necessary to take the appropriate measures<\/a> to minimise their presence and thus avoid high costs and unforeseen events.<\/p>\n<\/div><\/div>

Contaminaci\u00f3n externa<\/h3>\n

Las maquinarias que son m\u00e1s susceptibles de sufrir contaminaci\u00f3n externa son aquellas que se ubican en entornos hostiles, con alta presencia de polvo o humedad. En estos casos, cualquier operaci\u00f3n que se realiza en la m\u00e1quina, desde el cambio de lubricante o la revisi\u00f3n de niveles o componentes, hasta las tareas rutinarias de\u00a0mantenimiento<\/a>, pueden producir que agentes externos se introduzcan en el sistema de lubricaci\u00f3n, a\u00f1adiendo part\u00edculas abrasivas o agua que inciden negativamente en la vida \u00fatil del aceite y en el propio estado de la maquinaria.<\/p>\n

En este sentido, el m\u00e1s leve deterioro de los componentes de sellado, como el mal estado de una junta, puede ser la v\u00eda de acceso a estas part\u00edculas que influyen en la capacidad de limpieza del aceite lubricante.<\/p>\n

Otra fuente de contaminaci\u00f3n habitual son los rellenos inadecuados. Al verter un aceite incorrecto, se alteran las condiciones f\u00edsico-qu\u00edmicas del aceite, como su viscosidad. Si los componentes de los aceites son incompatibles, \u00e9stos producen reacciones qu\u00edmicas que atacan a las superficies, generan lodos que atascan la m\u00e1quina y derivan, en consecuencia, en un fallo cr\u00edtico.<\/p>\n

Los contaminantes externos son un problema frecuente pero, como hemos visto, no por ello menos importante<\/strong>. Es por eso que es necesario\u00a0tomar medidas<\/a>\u00a0para minimizar su presencia y evitar as\u00ed elevados costes e imprevistos.<\/p>\n<\/div><\/div>
