Description
включение электронагреватсльннлх элементов 2 в nporiapoaiioit камере /.the inclusion of electric heating elements 2 in nporiapoaiioit camera /.
При повышении температуры сверх заданной рычаг термографа отойдет от декал1а и вызовет отключение нагревателей. При о.х.лаждении и ириближеиии контакта к лекалу произойдет включение магнитного пускател , в результате чего профиль лекала станет пагон ть контакт на рыч.аге терм&графа, а нагреватели пропарочной камеры будут попеременно включатьс и выключатьс , тем самыМ регулиру заданную температуру.If the temperature rises above the set point, the thermograph lever will move away from decal and cause the heaters to turn off. During cooling operation and contact with the piece, the magnetic starter will turn on, causing the profile of the piece to begin contacting the lever of the & graph and the heaters of the steam chamber will turn on and off alternately, thereby adjusting the set temperature.
Предмет изобретени Subject invention
Способ ускоренного испытани цементов и бетонов дл определени их прочности в двадцативосьмидиевном возрасте путем автом атическон тепловлажностной обработки образцов, отл и ч а ю щи йс тем, что, с целью получени данных ускоренного испытани , сопоставимых с данными двадцативосьмидневных испытаний, образцы после изготовлени выдержнвают в течение двадцати четырех часов в тех же услови х, что и при двадцативосьмидневиых испытани х, после чего их подвергают в камере пропарке при температуре, повышающейс в течение четырех часов до 80, удерживаемой на этом уровне в течение часа и снижающейс в течение п тнадцати часов с 80 до 50, а затем охлаждают и подвергают обычным испытани м.The method of accelerated testing of cements and concretes to determine their strength at twenty-eight-eight years of age by automatic heat treatment of samples, except that, in order to obtain data of accelerated testing comparable to those of twenty-eight days of testing, the samples after production are kept for twenty-four hours in the same conditions as in the twenty-eight-day trials, after which they are subjected to steaming in the chamber at a temperature that rises to 80 in four hours, held at this level for one hour and reduced for fifteen hours from 80 to 50, and then cooled and subjected to the usual tests.
