Изобретение относитс к насосостроению , в частности к способам испытаний модельных , центробежных насосов, и вл етс усовершенствованием основного изобретени но авт. св. N° 844818.The invention relates to pump engineering, in particular to methods for testing model, centrifugal pumps, and is an improvement of the basic invention of the authors. St. N ° 844818.
Цель изобретени - повышение точности испытаний.The purpose of the invention is to improve the accuracy of the tests.
Способ реализуетс следуюп им образом .The method is implemented in the following way.
При испытани х модельного центробежного насоса с камерой уплотнени вала путем последовательного измерени потребл емой мощности насоса на рабочем режиме и на режиме холостого хода измер ют на рабочем режиме давление в камере уплотнени и поддерживают это давление на режиме .холостого хода. Кроме того, на режиме .холостого хода прикладывают к валу переменное осевое усилие, которое создают специальным , например, механическим или гидравлическим устройством. При этом за .мер ют значение мощности холостого хода и стро т тарировочный график в виде зависимости мощности холостого хода от величины осевой силы. Дл рабочих режимов насоса расчетным путем определ ют величину осевой силы и по тарировочному графику получают соответствующее значение мощности холостого хода.When testing a model centrifugal pump with a shaft seal chamber, measuring the power consumption of the pump successively in the operating mode and in the idle mode, the pressure in the seal chamber is measured in the operating mode and the pressure is maintained in the idle mode. In addition, in the idle mode, a variable axial force is applied to the shaft, which is created by a special, for example, mechanical or hydraulic device. At the same time, the value of the idling power is measured and the calibration curve is plotted in the form of the idling power depending on the axial force value. For the operating modes of the pump, the axial force is determined by calculation and the corresponding idle power value is obtained from the calibration curve.
Определение потребл емой мощности модельного насоса согласно предлагаемому способу позвол ет повысить точность результатов испытаний ввиду того, что учитываютс потери мош:ности не только в зависимости от давлени в камере уплотнени , но и от действи осевых сил.Determining the power consumption of a model pump according to the proposed method allows to increase the accuracy of the test results due to the fact that losses are taken into account: not only depending on the pressure in the seal chamber, but also on the effect of axial forces.
