Research on purification of the marine engine oil with chemical interaction preparation

Owing to additives, the lubricating oils are characterized by constantly improving properties. Nevertheless, in extreme hard working conditions of the tribological systems (high pressures, velocities and temperatures, temporary lubricating lack during starting) the machine elements are not secured enough. In connection with the above mentioned the idea to introduce the additional substance - operating preparation into tribological systems (with the lubricating oils) was put forward. Now the chemical interaction preparations have the widest application. These preparations are characterized by big molecular weight and high thermal and chemical stability. Besides filtering, lubricating oils used in marine engines are purified. In connection with it the question arises if the operating preparations (which have higher density then oils and water) are able to join permanently with lubricating oil in order not to separate in the purifying process and what influence they have on lubricating oil ability to separate the water. The lubricating oil with operating preparation MOTOR LIFE PROFFESIONAL and water purifying research were presented in the article so as to answer the above questions. The test stand consisted of two WESTFALIA purifiers. One of these purifiers was working in UNITROL, the other in SECUTROL system. In the research the UNITROL system purifier was used. The research object was MARINOL RG 1240 lubricating oil used in marine diesel engines.
