Description

(54) УСТРОЙСТВО ДЛЯ КОНТРОЛЯ ПРЕВЫШЕНИЯ ТЕМПЕРАТУРЫ ПОДШИПНИКОВ(54) DEVICE FOR CONTROLLING THE EXCEEDING THE TEMPERATURE OF BEARINGS

На чертеже показано устройство, схема.The drawing shows the device diagram.

Выходы термодатчиков 1 соединены с входами первого 2 и второго 3 элементов ИЛИ, выходы которых подключены к входам первого 4 и второго 5 пороговых элементов с исполнительными элементами 6 и 7 на выходах . Каждый термодатчик 1 выполнен в виде четырехплечего моста 8, состо щего из двух резисторов, терморезистора, стабилитрона и усилител  9, входы которого подключены к диагонали моста. К выходам датчиков через замыкающие кнопки 10 присоединен измерительный прибор 11. Терморезисторы помещены Б корпуса подшипников.The outputs of the thermal sensors 1 are connected to the inputs of the first 2 and second 3 elements OR, the outputs of which are connected to the inputs of the first 4 and second 5 threshold elements with actuators 6 and 7 at the outputs. Each thermal sensor 1 is made in the form of a four-shoulder bridge 8 consisting of two resistors, a thermistor, a zener diode and an amplifier 9, the inputs of which are connected to the diagonal of the bridge. To the outputs of the sensors through the closing buttons 10 is connected to the measuring device 11. Thermistors placed B bearing housing.

Устройство работает следующим образом .The device works as follows.

При начальной температуре подщипников мосты 8 термодатчиков 1 сбалансированы и сигналы на выходах усилителей 9 равны иулю. При нагрезе подщипников происходит разбаланс мостов, сигналы разбаланса усиливаютс , инвертируютс  усилител ми 9 и поступают на входы элементов 2 и 3 ИЛИ, на выходах которых выдел етс  сигнал от термодатчика наиболее нагретого подщипника . При достижении последним температурь , при которой необходим дальнейший контроль за подшипником со стороны обслуживающего персонала, срабатывают пороговый элемент 4 и исполнительный элемент 5, включа  предупредительную сигнализацию . При нагреве одного из подщипников до недопустимой дл  него температуры срабатывают пороговый элемент 5 и .исполнительный элемент 7, отключа  вращающуюс  машину и предотвраща  повреждение ее подшипников.At the initial temperature of the sub-supports, the bridges of 8 thermal sensors 1 are balanced and the signals at the outputs of the amplifiers 9 are equal to il. When the subspins are heated, the imbalance of the bridges occurs, the imbalance signals are amplified, inverted by the amplifiers 9 and fed to the inputs of elements 2 and 3 OR, at the outputs of which the signal from the temperature sensor of the most heated subshell is extracted. When the latter reaches the temperature at which further bearing control is required by the operating personnel, the threshold element 4 and the actuating element 5 are triggered, including the warning alarm. When heating one of the support parts to an unacceptable temperature, the threshold element 5 and the executive element 7 are activated, disabling the rotating machine and preventing damage to its bearings.

Дл  осуществлени  периодического контрол  температуры подшипников, служат кнопки 10 и измерительный прибор 11.To periodically monitor the temperature of the bearings, use the buttons 10 and the measuring device 11.

Технико-экономическа  эффективность от применени  изобретени  заключаетс Technical and economic efficiency of the application of the invention is

в упрощении путем уменьшени  количества термодатчиков, повышении чувствительности и быстродействи .in simplification by reducing the number of thermal sensors, increasing sensitivity and speed.
