Изобретение относитс к области испытани уплотнений.This invention relates to the field of seal testing.
Известен стенд дл испытани набивных сальниковых уплотнений, содержащий каме ру дл установки вала с испытываемым уплотнением, устройство дл подвода рабочей среды, устройство дл измерени давлени рабочей среды и св занные с ним трубки дл отбора рабочей среды между валом и испытываемым уплотнением. В этом стенде трубки дл отбора давлени установлены радиально через набивку и корпус камеры. Однако при переменном перепаде давлени на уплотнении нарушаетс его нормальна работа , так как подвижность уплотнени ограничена из-за фиксации его трубками.A test bench for packing stuffed seals is known, comprising a chamber for mounting a shaft with a test seal, a device for supplying a working medium, a device for measuring the pressure of a working medium and associated tubes for taking off the working medium between the shaft and the test seal. In this stand, pressure tubes are installed radially through the gasket and the camera body. However, with a variable pressure drop on the seal, its normal operation is disrupted, since the mobility of the seal is limited due to its fixation with tubes.
В предлагаемом стенде дл увеличени точности измерени трубки установлены с возможностью перемещени вдоль оси вала.In the proposed stand, in order to increase the measurement accuracy, the tubes are mounted for movement along the axis of the shaft.
На чертеже изображен предлагаемый стенд.The drawing shows the proposed stand.
Стенд содержит камеру / дл установки вала 2 с испытываемым набивным сальниковым уплотнением 3, устройство 4 дл подвода рабочей среды, устройство дл измерений давлений рабочей среды и св занные с нимThe stand contains a camera / for mounting the shaft 2 with the stuffed gland seal 3 under test, a device 4 for supplying the working medium, a device for measuring the pressures of the working medium and associated with it
трубки 5 дл отбора рабочей среды между валом 2 и испытываемым уплотнением 3.tube 5 for the selection of the working medium between the shaft 2 and the test seal 3.
Набивное сальниковое уплотнение испытывают следующим образом.Printed stuffing seal is tested as follows.
При вращении вала 2 и подаче давлени рабочей среды в устройство 4 между валом 2 и испытываемым уплотнением возникает жидкостной клин, распределение давлени в котором замер етс путем отбора жидкости трубками 5. При изменении перепада давлепи на уплотнении или подт жке уплотнени трубки 5 перемещаютс по осевым пазам расточки в камере / вместе с уплотнением 3.When the shaft 2 rotates and the pressure of the working medium is pumped into the device 4, a fluid wedge occurs between the shaft 2 and the seal under test, the pressure distribution in which is measured by fluid extraction by the tubes 5. When the pressure difference changes, the seal 5 moves along axial grooves bores in the chamber / together with the seal 3.
