Description
(54) СПОСОБ СТЕНДОВОГО ЗАПУСКА КРИОГЕННОГО(54) METHOD OF THE CRYOGENIC BENCH LAUNCH
НАСОСАPUMP
1one
Изобретение относитс к области испытаний криогенных насосов.This invention relates to the field of cryogenic pump testing.
Известны способы запуска криогенных насосов путем охлаждени его до рабочей температуры и раскрутки ротора насоса 1.Known methods for starting cryogenic pumps by cooling it to the operating temperature and unwinding the rotor of the pump 1.
В известных способах охлаждение насоса осуществл ют перед раскруткой ротора, что увеличивает врем запуска.In the known methods, the pump is cooled before the rotor is unrolled, which increases the start time.
Цель изобретени - сокращение времени запуска.The purpose of the invention is to reduce the launch time.
Указанна цель достигаетс тем, что охлаждение насоса и раскрутку ротора производ т одновременно.This goal is achieved by cooling the pump and spinning the rotor simultaneously.
При запуске число оборотов насоса увеличивают в соответствии с понижением температуры жидкости на входе в насос дл предотвращени кавитации. Принудительна подача жидкости увеличивает коэффициент теплоотдачи от насоса к охлаждающей жидкости и снижает врем охлаждени , а значит и врем запуска.At start-up, the speed of the pump is increased in accordance with a decrease in the temperature of the fluid entering the pump to prevent cavitation. The forced flow of fluid increases the heat transfer coefficient from the pump to the coolant and reduces the cooling time, and hence the start time.
