Bus/Financial - الاقتصاد | | أنجليزي مصطلح أو جملة: 90 weight | Описание насоса:
The 90 weight gear oil is used for high-pressure pumps using 1/2 horsepower motors or larger and rated for operation
over 1000 PSI.
Не могу понять, что здесь означает 90 weight Это не опечатка. никакие граммы и килограммы не пропущены - далее в тексте встречается еще раз.
Перевод:
Редукторное масло 90 weight* используется для насосов высокого давления с электродвигателями мощностью 1/2 лошадиной силы или более и рассчитано на рабочее давление более 1000 фунтов на кв. дюйм.
Спасибо!

The viscosity grade (for example, 5W-30) tells you the oil's thickness, or viscosity. A thin oil has a lower number and flows more easily, while thick oils have a higher number and are more resistant to flow. Water has a very low viscosity -- it is thin and flows easily. Honey has a very high viscosity -- it is thick and gooey.
The standard unit used to measure viscosity is the centistoke (cSt). According to the Automotive and Industrial Lubricants Glossary of Terms:
Viscosity is ordinarily expressed in terms of the time required for a standard quantity of the fluid at a certain temperature to flow through a standard orifice. The higher the value, the more viscous the fluid. Since viscosity varies inversely with temperature, its value is meaningless unless accompanied by the temperature at which it is determined. With petroleum oils, viscosity is now commonly reported in centistokes (cSt), measured at either 40°C or 100 °C (ASTM Method D445 - Kinematic Viscosity).
The centistoke rating is converted into the SAE weight designation using a chart like the one shown on the Superior Lubricants Web site.

شرح:
Gear oil is heavy oil, rated at 80 to 100 weight viscosity that is used in enclosed units containing gears. Industrial gear oils are multigrade lubricants containing sophisticated extreme pressure additives. The viscosity of the oil should be high enough to muffle gear teeth and protect against failure. The viscosity is selected based on the system's requirements. Viscosity is the most important property of gear oil. The rate of change of viscosity with temperature is called the viscosity index. The ability of oil to maintain a small viscosity differential over the operating range of gearbox provides a more consistent lubricating films to the gears and more predictable wear performance

شرح:
С сайта производителя масел:
"0W-30, 5W-30 and 10W-30 synthetic motor oils are ALL 30 weight oils. The answer is that ANY one can be used regardless if your vehicle owners manual says to use, for example, a 5W-30. "W" means winter. In winter weather the 0W oil will flow like a 0W oil, and the 5W will flow like a 5W oil and a 10W will flow like a 10W oil just until the engine warms up. In order to understand the differences one has to first understand that the numerical values given to these various weight oils are strictly empirical numbers. For example, 0W does not mean that the oil has no weight. That is one of the reasons why we say it is strictly an empirical number."
