Изобретение относитс к области гидромашиностроени , а именно к способам балансовых испытаний модельных центробежных насосов.The invention relates to the field of hydraulic engineering, in particular to methods of balance testing of model centrifugal pumps.
Известен способ испытаний модельного центробежного насоса с камерой уплотнени вала, включающий последовательное измерение потребл емой мощности насоса на рабочем режиме и на режиме холостого хода Л1 .A known method of testing a model centrifugal pump with a shaft seal chamber, which includes the sequential measurement of the pump power consumption in the operating mode and in the idle mode L1.
Однако известный способ не обеспечивает доста очную точность при определении , например, полезной потребл емой мощности и КПД, при отработке ступеней модельного насоса, так как потери мощности в сальниковом или торцовом уплотнении вала завис т от давлени , которое поддерживаетс вкамере уплотнени .However, the known method does not provide sufficient accuracy in determining, for example, useful power consumption and efficiency when developing stages of a model pump, since the power loss in the packing or end shaft seal depends on the pressure that is maintained in the seal chamber.
Целью насто щего-изобретени вл етс повышение, точности испытаний.The purpose of the present invention is to increase the accuracy of the tests.
Цель достигаетс тем, что на рабочем режиме дополнительно измер ют давление в камере уплотнени и поддерживают это давление на режиме холостого хода.The goal is achieved by the fact that, during the operating mode, the pressure in the seal chamber is additionally measured and this pressure is maintained at idle mode.
На чертеже представлен график зависимости мощности холостого хода NXJ от давлени в камере торцовогоThe drawing shows a graph of the idle power NXJ versus the pressure in the end-face chamber
уплотнени вала Р, полученный дл одного из испытываемых насосов.shaft seal P obtained for one of the pumps tested.
Способ испытаний модельного центробежного насоса реализуют следующим образом.The method of testing a model centrifugal pump is implemented as follows.
Последовательно измер ют потребл емую насосом мощность на рабочем режиме и на режиме холостого хода, причем на рабочем режиме дополнитель10 но измер ют давление в камере уплотнени и поддерживают это давление на режиме холостого хода.The power consumed by the pump is successively measured in the operating mode and in the idle mode, while in the operating mode the pressure in the seal chamber is additionally measured and the pressure is maintained in the idle mode.
Измерение мощности,потребл емой насосом, производитс известным способом, например, с применением балансирного электродвигател .Measurement of the power consumed by the pump is carried out in a known manner, for example, using a balance motor.
По результату испытаний установлено , что такой способ обеспечивает уменьшение погрешности измерени по20 лезной мощности с 6% до 1%, а КПД с 6,5% до 1,5% по сравнению с известным способом.According to the test results, it was found that such a method provides a reduction in the measurement error of the effective power from 6% to 1%, and the efficiency from 6.5% to 1.5% in comparison with the known method.
