t4-contribution from shaft seal-safety margin см. Explanation: значение температуры для группы воспламеняемости T4 - (минус) составляющая температуры уплотнения вала - (минус) запас надежности -------------------------------------------------- Note added at 25 мин (2020-01-22 08:44:34 GMT) -------------------------------------------------- Temperature Classes The ignition temperature of a flammable gas/liquid is the lowest temperature of a hot surface at which ignition of the gas/air or vapour/air mixture takes place. The maximum surface temperature of the equipment must therefore be lower than the ignition temperature of the ambient atmosphere. Temperature classes T1 to T6 have been introduced for electrical equipment within a Group II hazardous area. Class Hazards which will not ignite at temperature below: T1 450°C T2 300°C T3 200°C T4 135°C T5 100°C T6 85°C https://www.sensorland.com/HowPage109.html |

Температурный класс T4 - влияние уплотнения вала - запас надежности Explanation: Ловите, там все уже описано. Страница 7, по-моему. Откорректируйте и переводите на здоровье :) file:///C:/Users/HP/Desktop/Programmi/Grundfosliterature-3417.pdf -------------------------------------------------- Note added at 41 mins (2020-01-22 08:59:50 GMT) -------------------------------------------------- Простите, сбросила ссылку на свой ПК (бывает). Попробуйте вставить текст и по нему ищите документ На основании температурного влияния уплотнения вала HQQX, класса среды 1, диаметра вала ∅22 и давления 2,5 MПa. Класс температур (T4) = 135 ... |
