Description

обмотке 6 соленоида. Магнитное поле основной обмотки соленоида вт гивает се; дечник 5, который через рычажную систему 8 воздействует на каретку 2 и подводит очистной инструмент 1 к очищаемой трубе. В момент касани  инструментом издели  замыкаетс  электрическа  цепь рабочего напр жени  и ток проходит через дополнительную обмотку 7 соленоида. Если инструмент касаетс  издели  с усилием большим номинального, то электрическое сопротивление между изделием и рабочим инструментом мало, а сила тока, проход щего через дополнительную обмотку соленоида, велика. Поскольку дополнительна  обмотка соленоида имеет оббратную пол рность и усилие магнитного пол  ее совпадает с иаправлением действи  пружинного механизма 9 отвода очистного инструмента, то инструмент отходит от издели  на величину, обеспечивающую номинальнзю величину усили  касани . Таким образом, обеспечиваетс  посто нство нат га и гарантированное горение электрической дуги.winding 6 solenoid. The magnetic field of the main winding of the solenoid engages ce; The dead plate 5, which through the lever system 8 acts on the carriage 2 and brings the cleaning tool 1 to the pipe being cleaned. When the instrument touches the product, the electric circuit of the operating voltage closes and the current passes through the additional winding 7 of the solenoid. If the instrument touches the product with a force greater than the nominal, then the electrical resistance between the product and the working tool is small, and the current through the additional coil of the solenoid is large. Since the additional solenoid winding has a reverse polarity and the magnetic field force coincides with the direction of the spring mechanism 9 to remove the cleaning tool, the tool moves away from the product by an amount that provides the nominal value of the contact force. Thus, a constant tension and guaranteed burning of the electric arc are provided.
