Abstract
Изобретение относитс к области, испытани на трение и может найти применение дл определени потерь на трение в спиральных трубопроводах. Целью изобретени вл етс увеличение информативности за счет обеспечени измерени силы трени в любой точке трубы 3, выполненной в виде змеевика, намотанного на цилиндр 1, который установлен на основании 2 с возможностью вращени . Сматыва с цилиндра 1 по витку трубы, на выходе датчиком 7 измер ют силу трени и получают зависимость силы трени от количества витков змеевика трубы. 2 ил. фаг. 2The invention relates to the field of friction testing and can be used to determine friction losses in spiral pipelines. The aim of the invention is to increase the information content by providing a measurement of the frictional force at any point of the pipe 3, made in the form of a coil wound on a cylinder 1, which is mounted on the base 2 with the possibility of rotation. Winding from cylinder 1 along the turn of the pipe, at the outlet of sensor 7, the force of friction is measured and the dependence of the force of friction on the number of turns of the pipe coil is obtained. 2 Il. phage. 2
Description
Изобретение относитс к испытани м на трение и может найти применение дл определени потерь на трение в спиральных трубопроводах.The invention relates to friction tests and can be used to determine friction losses in spiral pipelines.
Целью изобретени вл етс увеличение информативности за счет обеспечени измерени силы трени в любой точке змеевика.The aim of the invention is to increase the information content by providing measurement of the frictional force at any point of the coil.
На фиг. 1 изображено устройство дл реализации способа, вид спереди, на фиг. 2 - то же, вид сбоку.FIG. 1 shows a device for implementing the method, front view; FIG. 2 - the same, side view.
Устройство содержит цилиндр 1, установленный на основании 2 с возможностью вращени , эластичную трубу 3, намотанную на цилиндр 1 в виде змеевика с пр молинейными участками 4 и 5 на концах. На одном конце тру бы закреплен штуцер 6 дл соединени с источником газа (не показан), а на другом в месте перехода криволинейного участка в пр молинейный установлен датчик 7 измерени силы трени .The device comprises a cylinder 1 mounted on a base 2 rotatably, an elastic pipe 3 wound on a cylinder 1 in the form of a coil with rectilinear sections 4 and 5 at the ends. At one end of the pipe, a nozzle 6 is fixed to be connected to a gas source (not shown), and at the other end, a sensor 7 for measuring friction force is installed at the transition point of the curvilinear section to a straight line.
Способ осущест:вл етс следующим образом.Implement method: is as follows.

В трубу 3, выполненную в виде змеевика, подают газ. Сматыва с цилиндра 1 по одному витку змеевика трубы 3 на выходе, измер ют силу трени датчиком 7 и получают зависи- мость силы трени от количества витков змеевика. Пр молинейные участки необходимы дл выравнивани течени потока.In the pipe 3, made in the form of a coil, serves gas. Winding from cylinder 1 one turn of the coil of the pipe 3 at the outlet, measure the frictional force of the sensor 7 and get the dependence of the frictional force on the number of turns of the coil. Straight line portions are needed to smooth flow.
