Description
(5А) СПОСОБ ОПРЕДЕЛЕНИЯ ТЕМПЕРАТУРЫ ДВИЖУЩЕЙСЯ НИТИ(5A) METHOD FOR DETERMINING THE TEMPERATURE OF A MOVING THREAD
1one
Изобретение относитс к термометрии , а именно к измерению температуры движущейс нити при ее производстве на однопроцессной машине ложного кручени .The invention relates to thermometry, namely to measuring the temperature of a moving thread during its production on a single-process false-torsion machine.
Известен способ измерени температуры движущейс нити, заключающийс в том, что ввод т в контакт с нитью рабочий спай термопары и измер ют его температуру l .юA known method for measuring the temperature of a moving filament is that the working junction of the thermocouple is brought into contact with the filament and its temperature is measured.
Однако известный способ не обладает требуемой точностью измерени изза погрешности, обусловленной дополнительным нагревом спа термопары за счет трени .15However, the known method does not have the required accuracy of measurement due to the error caused by the additional heating of the thermocouple spa due to friction .15
Наиболее близким по технической сущности к изобретению вл етс способ определени температуры движущейс нити, заключающийс в том, что 20 ввод т в механический контакт с движущейс нитью в зоне термообработки неподвижный рабочий спай термопары и измер ют его температуру 2 . The closest to the technical essence of the invention is a method for determining the temperature of a moving filament, namely, that the stationary working junction of the thermocouple is brought into mechanical contact with the moving filament in the heat treatment zone and its temperature is measured 2.
Однако известный способ не обладает требуемой точностью измерени из-за погрешности, обусловленной нагревом рабочего спа , которое выдел етс при трении между термопарой и нитью.However, the known method does not have the required measurement accuracy due to the error due to the heating of the working spa, which is released during friction between the thermocouple and the filament.
Цель изобретени - повышение точности измерени . .The purpose of the invention is to improve the measurement accuracy. .
Дл достижени цели ввод т в механический контакт с движущейс нитью неподвижный рабочий спай термопары в зоне,где нить имеет температуру окружающей среды, измер ют температуру рабочего спа термопары в этой зоне и температуру окружающей среды, а искомую температуру нити определ ют как сумму между температурой рабочего спа в зоне термообработки и разность между температурами окружающей среды и рабочего спа в зоне, где нить имеет -температуру окружающей среды.To achieve the goal, the stationary working junction of the thermocouple is brought into mechanical contact with the moving thread in the zone where the thread has an ambient temperature, the temperature of the working thermocouple spades in this zone and the ambient temperature are measured, and the desired temperature of the thread is determined as the sum between the operating temperature the spa is in the heat treatment zone and the difference between the ambient temperature and the working spa in the zone where the thread has is the ambient temperature.
