The course is THOR-105. The density of the oil, pour point, flash point

The company BALTECH invites all technicians training course TOR-105 "Tribodiagnostics. Basics lubrication of machines and equipment". These courses are held us once in two months. This course addresses issues tribotechnology.

Density is a fundamental the property is oil, which is measured in kg/m3 at temperatures of +15°C or 20°C. Depending on the type and quality of base oils and additive packages density oils is from 700 to 950 kg/m3. Is determined according to GOST 3900-85.

Pour point - the temperature at which the oil remains stationary under the action of gravity (not flowing). This temperature should be below 5-7°C temperature pumping oil in the lubricating system of the engine. Unambiguous relationship temperature pour oil from its starting properties in the cold does not exist. Determined according to GOST 20287-91.

Flash point - the lowest the temperature at which the vapors of hydrocarbons from oil to form an air mixture, can, by introducing an external source of fire to ignite. Temperature outbreaks associated with fractional composition of oil and the molecular structure of the base components. Under other equal conditions of high temperature flash the preferred. A significant decrease in flash point at the investigated oils can talk about diluting the oil with fuel. Is determined according to GOST 4333-87 and GOST 6356-75 (GOST R EN ISO 2719-2008) and GOST R 53717-2009.

Ignition temperature - the minimum temperature at which the pair above the surface of the heated oil are formed with such speed that when a present to him an open fire a pair of light up and burn at least 5 C. Usually the ignition temperature is higher than the flash point of at 10-50°C. is Determined according to GOST 4333-87.

Total base number (TBN) reflects stock the neutralizing properties of the oil that is created is added to the oil and detergents dispersant additives that have alkaline properties.

The more alkaline the number, the better than the oil to neutralize acids formed during the oxidation and the combustion of the fuel.

Is determined according to GOST 30050-93 (ISO 3771-77), GOST 11362-96 (ISO 6619-88) and GOST 29255-91 (ISO 6618-87).
