НАСОСОВPUMPS
1one
Изобретение относитс к гидромашиностроению , более конкретно к конструкци м стендов.дл испытаний насосов.The invention relates to hydraulic engineering, more specifically to the design of test benches for testing pumps.
Известен стенд дл кавитационных испытаний насосов, содержащий расходный бак, св занный с испытываемым насосом посредством всасывающего и напорного трубопроводов с запорными органами 1.A stand for cavitation testing of pumps is known, containing a supply tank associated with the test pump through suction and pressure pipelines with shut-off members 1.
Недостатками известного стенда вл ютс больща продолжительность испытаний и низка точность получаемых результатов .The disadvantages of the known stand are the longer test duration and the low accuracy of the results obtained.
Наиболее близким к изобретению по технической сущности И достигаемым результатам вл етс стенд дл кавитационных испытаний , содержащий расходный бак, св занный с испытываемым насосом посредством всасывающего н нагнетательного трубопроводов с запорными органами, и герметичную емкость с дренажным краном и уровнемером, подсоединенную к всасывающему трубопроводу посредством подвод щей гидролинии 2.The closest to the invention of the technical essence and the achieved results is a cavitation test bench containing a supply tank connected to the test pump through suction and discharge piping with shut-off members, and a sealed container with drain valve and level gauge connected to the suction piping by connecting hydraulic hose 2.
Недостатком этого стенда вл етс невысока точность результатов, обусловленна невозможностью регулировать скоростьThe disadvantage of this stand is the low accuracy of the results, due to the inability to adjust the speed
снижени уровн жидкости в герметичной емкости.lowering the fluid level in an airtight container.
Целью изобретени вл етс повыщение точности испытаний.The aim of the invention is to increase the accuracy of the tests.
Поставленна цель достигаетс тем, чтоThe goal is achieved by the fact that
5 герметична емкость посредством патрубка5 hermetic tank by pipe
с запорным органом подключена к нагнетательном-у трубопроводу, а входное сечениеwith shut-off body connected to the injection-y pipeline, and the input section
подвод щей гидролинии расположено нижеdownstream hydroline is located below
горизонтальной плоскости, проход щей рез ось насоса.horizontal plane passing through the axis of the pump.
Кроме того, расходный бак и герметична емкость посредством перепускной магистрали св заны между собой.In addition, the supply tank and the sealed container are connected to each other via a bypass line.
На чертеже представлена схема стенда.The drawing shows the scheme of the stand.
