Description
Изобретение относитс к технической диагностике, а именно к устройствам дл креплени тензодатчика к диагностируемому трубопроводу гидравлических систем, в частности топливной системы двигателей внутреннего сгорани .The invention relates to technical diagnostics, in particular, to devices for attaching a strain gauge to a pipeline being diagnosed of hydraulic systems, in particular the fuel system of internal combustion engines.
Известно устройство дл креплени тензодатчика к трубопроводу, в котором последний устанавливаетс в рабочее положение при помощи специального переходного приспособлени .A device is known for attaching a strain gauge to a pipeline, in which the latter is placed in an operating position using a special adapter.
Недостатком известного устройства вл етс сложность установки тензодатчика на трубопровод.A disadvantage of the known device is the difficulty of installing a strain gauge on the pipeline.
Наиболее близким к предлагаемому устройству по технической сущности вл етс устройство дл креплени тензодатчика на трубопроводе, содержащее тензодатчик и шарнирно соединенные и подпружиненные рычаги с выемками под трубопровод 2.The closest to the proposed device according to the technical essence is a device for fastening a strain gauge on a pipeline, which contains a strain gauge and pivotally connected and spring-loaded levers with notches for pipeline 2.
Однако известное устройство не обеспечивает непосредственный контакт тензодатчика с трубопроводом.However, the known device does not provide direct contact of the strain gauge with the pipeline.
Цель изобретени - обеспечить .контакт тензодатчика с трубопроводомThe purpose of the invention is to provide .contact load cell with pipeline
Это достигаетс .тем, что в выемках рычагов установлена эластична This is achieved. The fact that in the grooves of the levers is set elastic
прокладка, к которой с помощью кле прикреплен тензодатчик.laying to which with the help of glue the strain gage is attached.
На фиг. 1 показано предлагаемое устройство, общий вид; на фиг. 2 -. схема прибора дл измерени средней и пульсирующей составл ющих давлени .FIG. 1 shows the proposed device, a general view; in fig. 2 -. a circuit for measuring the average and pulsating pressure components.
Устройство содержит два щарнирно соединенных между собой рычага 1 и 2, The device contains two pivotally interconnected levers 1 and 2,
0 концы которых подпружинены пружиной 3, котора создает необходимое усилие прижима рычагов к трубопроводу 4.0 the ends of which are spring-loaded spring 3, which creates the necessary force of pressing the levers to the pipeline 4.
Рычаги имеют выемки под трубопровод , в которых установлены проклад5 ки 5 и б из эластичного материала, например резины. К поверхности прокладок при помощи кле прикреплены тензодатчики 7 и 8, которые включены в одно плечо мостовой схемы. The levers have grooves for the pipeline in which gaskets 5 and b are made of an elastic material, for example, rubber. Strain gauges 7 and 8 are attached to the surface of the gaskets with glue, which are included in one shoulder of the bridge circuit.
0 Мостова схема включает в себ резисторы 9, 10 и 11 и источник питани 12. Измерительна диагональ моста подключена ко входу тензометрического усилител 13.0 The bridge circuit includes resistors 9, 10 and 11 and a power source 12. A bridge diagonal measurement is connected to the input of the strain gauge amplifier 13.
5five
На выходе тензометрического усилител установлены два измерительных прибора 14 и 15, например миллиамперметра , один из которых подключен к выходу усилител через интегри0 рующую RC-цепочку 16 и 17, а второйAt the output of the strain gauge amplifier, two measuring devices 14 and 15 are installed, for example, a milliammeter, one of which is connected to the output of the amplifier through an RC circuit 16 and 17, and the second
