(54) СПОСОБ ОПРЕДЕЛЕНИЯ МОЩНОСТИ, ПОТРЕБЛЯЕМОЙ СТУПЕНЬЮ МОДЕЛЬНОГО НАСОСА(54) METHOD FOR DETERMINING POWER CONSUMED BY THE STAGE OF A MODEL PUMP
II
Изобретение относитс к насосостроению.The invention relates to a pump engineering industry.
Известен способ определени мощности, потребл емой ступенью модельного насоса с радиальными подшипниками, установленными в корпусе масл ной ванны, путем измерени балансирным двигателем мощности на валу насоса на заданном режиме его работы и мощности холостого хода 1.A known method for determining the power consumed by a stage of a model pump with radial bearings mounted in the housing of an oil bath is measured by a balanced motor for power on the pump shaft at a given mode of operation and at idle speed 1.
При реализации известного способа на точность определени мощности холостого хода модельного насоса вли ет температура масла в корпусе радиальных подщипников, что вносит погрешность в результаты испытаний в целом.When implementing the known method, the accuracy of determining the idling power of a model pump is influenced by the oil temperature in the housing of the radial bearings, which introduces an error in the test results as a whole.
Целью изобретени вл етс повышение точности.The aim of the invention is to improve the accuracy.
Достигаетс это тем, что при измерении мощности на валу насоса дополнительно измер ют температуру масла в масл ной ванне и выдерживают эту величину при измерении мощности холостого хода.This is achieved by measuring the power at the pump shaft to additionally measure the temperature of the oil in the oil bath and withstand this value when measuring the idle power.
На чертеже изображен график зависимости мощности холостого хода модельного насоса в зависимости от температуры масла.The drawing shows a graph of the idling power of a model pump versus oil temperature.
Способ определени мощности, потребл емой ступенью модельного насоса с радиальными подшипниками, установленными вThe method for determining the power consumed by the stage of a model pump with radial bearings mounted in
корпусе масл ной ванны, заключаетс в измерении балансирным двигателел мощности на валу насоса на заданном режиме его работы и мощности холостого хода, а при измерении мощности на валу насоса дополнительно измер ют температуру масла в масл ной ванне М выдерживают эту величину при измерении мощности холостого хода.the body of the oil bath consists in measuring the engine with the balancing power on the pump shaft at a predetermined mode of operation and idling power, and when measuring the power on the pump shaft, the temperature of the oil in the oil bath M is also maintained with this value when measuring the idling power.
Реализаци описываемого способа повышаетс точность определени мощности fQ и КПД ступени модельного насоса. В результате этого повышаетс и точность прогнозировани характеристик натурных насосов, пересчитываемых с характеристик ступени модельного насоса.The implementation of the described method improves the accuracy of determining the power fQ and the efficiency of the stage of the model pump. As a result, the accuracy of prediction of the characteristics of full-scale pumps, recalculated from the characteristics of the stage of the model pump, is increased.
