Изобретение касаетс испытательной техники и может быть использовано при проведении испытаний гидромашин.The invention relates to testing equipment and can be used in testing hydraulic machines.
Известны стенды дл испытаний гидромашин , содержащие открытый напорный бак, соединенный подвод щим трубопроводом с испытуемой гидромашиной, отсасывающа труба которой св зана с расходов мерным лотком с размещенным на его конце водосливом. ; Однако такие стенды невозможно ио пользовать дл испытани насосов или обратимых гидромашин, поскольку расходомерные водосливы, примен емые в этих стендах, могут измер ть расход лишь о ного направлени . С П мощью расходомер, ных устройств, установленных на этих стендах, невозможно быстро измен ть воврем переходные процессы расходов по величине и направлению. Test benches for hydraulic machines are known, which contain an open pressure tank connected by a supply pipe to a test hydraulic machine whose suction pipe is connected to the flow rate of a measuring tray with a spillway placed at its end. ; However, such stands cannot be used to test pumps or reversible hydraulic machines, since the flow metering weirs used in these stands can measure the flow rate only in the normal direction. With the use of a flow meter, devices installed on these stands, it is not possible to quickly change the transients of expenditures in magnitude and direction in time.
Целью изобретени вл етс обесп&|чение исследовани обратимых гидромашин и переходных процессов, происход щих, :Как в турби1шом, так и в насосном режимах .The aim of the invention is to provide a study of reversible hydraulic machines and transient processes occurring: In both the turbo and pumping modes.
Дл этого напорный бак и расходомер;Ный лоток дополнительно соединены обвоа;Ным трубопроводом, снабженным дроссельр .ным расходомером и задвижкой, а в подвод щем трубопроводе установлен двухсторонний бесконтактный расходомер.For this purpose, the pressure tank and the flow meter; The new tray is additionally connected by a pipe; The pipeline, equipped with a flow meter throttle valve and a gate valve, and a two-way contactless flow meter is installed in the supply pipeline.
На чертеже представлен предложенный стенд, продольный.разрез.The drawing shows the proposed stand, longitudinal.
Стенд содержит напорный бак 1, со&диненный ПОДВОД5ПЦИМ трубопроводом 2 с испытуемой гидромашйной 3, отсасываюша труба 4 которой св зана с расходомерным лотком 5, снабженным водосливом 6, Под |расходомерным лотком размещен сливной |бак 7, в котором размещены насосы 8 дл перекачки воды из сливного бака 7 в напорный бак 1. Параллельно проточному тракту испытуемой гидромашины проложен обводной трубопровод 9, соедин ющий напорный бак 1 с расходомерным лотком 5. На трубопроводе 9 установлен дросселыный расходомер) 10 и задвижка 11, а на подвод щем трубопроводе размещен бесконтактный расходомер.: 12. На валу испытуемой гидромашины 3 устпловлен The stand contains a pressure tank 1, a joint SUBDU 5PCIM pipe 2 with the test hydromachine 3, which pipe 4 is sucked out with a flow meter 5 equipped with a weir 6, Drain tank 7 is placed under the flow meter where pumps 8 are placed for pumping water from the drain tank 7 into the pressure tank 1. In parallel with the flow path of the test hydraulic machine, a bypass pipe 9 is installed connecting the pressure tank 1 with the flow meter 5. Pipe 9 has a throttle flow meter 10 and valve 11, and oprovode placed contactless flowmeter .: 12. On the shaft 3 of the hydraulic test ustplovlen
балансирна электромашина 13 посто н ного тока.balancing electric machine 13 dc.
Размеры напорного бака 1 и расходо- мерного лотка 5 подобраны таким образом, чтобы за врем переходного процесса в результате изменени отметок верхнего и нижнего бьефов, вследствие нарушени баланса расходов насосов 8 и - испытуемой машины 3, напор измен лс бы более чем на 1%. В случае испытаний, например, обратимой гидромашины в турбинном режиме и при переходных режимах, задвижка 11 закрыта, расход измер етс двухсторонним индукционным расходомером 12. В случае испытаний в насосном режиме задвижка 11 частично открыта. Вода, изливающа с из обводного трубопровода в лоток, частично засасываетс гидромашиной, а излишек ее переливаетс -через водослив 6.The dimensions of the pressure tank 1 and the flow chute 5 are selected so that during the transition process as a result of changes in the upstream and downstream elevations, due to the imbalance of the flow rates of the pumps 8 and - of the tested machine 3, the head would change by more than 1%. In the case of tests, for example, reversible hydraulic machines in turbine mode and under transient conditions, the valve 11 is closed, the flow rate is measured by a two-way induction flow meter 12. In the case of tests in pumping mode, the valve 11 is partially open. The water pouring from the bypass line into the tray is partially sucked in by the hydromachine, and the excess is poured over the weir 6.
Следовательно, подача гидромашины на установившемс режиме определ етс как разность между расходом, измеренным дроссельным расходомером 10 и расходом.Consequently, the flow rate of the hydraulic machine in the steady state is defined as the difference between the flow rate measured by the throttle flow meter 10 and the flow rate.
