(54) СПОСОБ КАВИТЛЦИОННЫХ ИСПЫТАНИЙ ЛОПАСТНЫХ НАСОСОВ(54) METHOD OF CAVITLATION TESTS OF BLANED PUMPS
Claims (1)
Формула изобретенияClaimСпособ кавитационных испытаний лопастных насосов на моделирующей жидкости, включающий перепуск части потока жидкости из полости высокого давления насоса на вход рабочего колеса в его периферийную зону по каналу, расположенному параллельно оси насоса, отличающийся тем, что, с целью расширения диапазона и повышения точности испытаний, перепускаемую часть потока жидкости нагревают.The method of cavitation testing of vane pumps on a simulating fluid, comprising bypassing part of the fluid flow from the high-pressure cavity of the pump to the inlet of the impeller into its peripheral zone along a channel parallel to the axis of the pump, characterized in that, with the aim of expanding the range and improving the accuracy of the tests, the bypass part of the fluid flow is heated.
