Impiegabile anche nelle seghe a telaio fortemente sollecitate. Βιομηχανικό λάδι σασμάν υψηλής ποιότητας, απογαλακτοματοποίησης σε βάση ορυκτέλαιου με υψηλή ανθεκτικότητα στη γήρανση και πολύ καλή φέρουσα ικανότητα. Please read for more information about how you can control adserving and the information collected. The viscosity of each grade ranges ± 10 % from the mid-point. For lubricating oils, viscometers tend to operate by gravity rather than pressure.
Ceci entraîne ainsi une réduction de l´usure. Understanding the relationship of the viscosity scales to one another is useful but the viscosity of an oil is only part of what makes an oil a proper lubricant for a particular application. Circulating oil is engineered to lubricate as well as separate water from oils when used on bearings, gears, metal surfaces and machine systems. Water goes through in one second. A study of possible temperatures indicated that 40ºC 104ºF was suitable for the industrial-lubricant classification as well as for the lubricant-definition properties mentioned above. Oil viscosity is measured several ways.
While all of these have served useful purposes to one degree or another, most lubrication practitioners settle on and use one method as a basis for selecting products. Aceite para engranajes industriales, desmulsificante, de alta calidad, de base mineral, muy resistente al envejecimiento y excelente capacidad de carga. It maintains viscosity over long periods of time and has a good thermal stability. This would reflect an order of center point uncertainty in calculations similar to that imposed by dimensional manufacturing tolerances. Given all of these variables and details, several organizations decided to come up with a way to characterize lubricating oils so that members of their respective organizations would have a uniform and simple way to communicate, educate and ultimately protect their interests.
This property is called absolute viscosity also known as dynamic viscosity and is measured in centipoises cP. Utilizabil şi în gaterele supuse unor solicitări extreme. It has a low traction coefficient relative to mineral oils and is generally compatible with other Polyalphaolefin based synthetics and mineral oils. Select a Product Category Below. Water has a low viscosity of 1 cSt and honey has a very high viscosity, lets say 1,000 cSt.
For vehicles, machinery, workshops, trade and industry. It performs well under varied conditions and is an economical alternative to synthetic oils. To determine the centipoise of a fluid it is necessary to multiply the viscosity of the fluid times the specific gravity of the fluid, or measure it directly using an absolute viscometer. That is at the bottom of the cSt scale. Please read for more information. Since its inception in 1975, the organizations have developed 20 viscosity gradients to cover the range of oils and lubricants that are common in hydraulic application.
Use the following chart to better understand the relationship of the viscosity measurement scales only. Its lower traction coefficient can provide reduced power consumption and lower operating temperatures. Efficiency improvements will vary based on operating conditions and application. As the viscosity of the oil increases, so does the density of the material, as a higher density results in oil that is less likely to respond to flow or other movement. Because the conditions are repeatable, it is now possible to measure the amount of time that it takes for the fluid to flow through the tube, and it should be nearly the same each time. A perhaps more common use of hydraulic oils is the oil that automobiles use for braking brake fluid.
Add the Engineering ToolBox extension to your SketchUp from the Sketchup Extension Warehouse! If the machine runs very fast then the machine designer will specify a lubricant that can get out of the way, and back into the way just as quickly. Mineral oil is a liquid by product made from petroleum. The logarithmic series has been rounded off for the sake of simplicity. Применяется также в высоконагружаемых бензопилах. Questo porta a sua volta ad una riduzione dell´usura.
To the new entrant into the lubrication field, the number of options can be confusing, particularly if the primary lubricant supplier does not associate one of the prominent viscosity systems to the product label. Można go stosować także w trakach pionowych podlegających wysokim obciążeniom. Through the years, lubricant users have been treated to a number of ways to designate viscosity grades of the lubricants used in manufacturing. The grade is a literal measurement of the oil's ratio of absolute viscosity in centipoise a unit of measurement to the density, also known as centistoke.
