(54) СПЮСОБ КАВИТАЦИОННОГО ИСПЫТАНИЯ ЛОПАСТНОГО(54) THE SPEACH OF CAVITATION TESTING OF VEHICLE
НАСОСАPUMP
Изобретение касаетс испытаний лопастных насосов, в частности кавитационного испытани насосов, и может быть использовано при проверке кавитационных характеристик -питателных насосов паровых котлов в химической про мышленности и криогенной технике.The invention relates to the testing of vane pumps, in particular the cavitation test of pumps, and can be used in testing the cavitation characteristics of boiler boilers in the chemical industry and cryogenic technology.
Известны способы кавитационного -испытани лопастного насоса на жидкости с различной температурой путем прокачки жидкости через основной насос при помощи вспомогательного насоса. II.Known methods of cavitation test of a vane pump on a liquid with different temperatures by pumping fluid through the main pump using an auxiliary pump. Ii.
.Недостатками таких способов испытаний вл етс высока трудоемкость и сложность, св занна с необходимостью поддержани посто нного теплового режима.The disadvantages of such test methods are the high labor intensity and complexity associated with the need to maintain a constant thermal regime.
Цель изобретени - снижение трудоемкости и упрощение способа испытаний лопастного насоса.The purpose of the invention is to reduce the labor intensity and simplify the method of testing a vane pump.
Это достигаетс тем, что при посто нном входном давлении, соответствующем режиму кавитадионного запирани рабочего колеса основного насоса, измен ют температуру жидкости и измер ют соответствующую каждому значению температуры величину расхода жидкости через основной насос.This is achieved by the fact that at a constant inlet pressure corresponding to the mode of cavitational locking of the impeller of the main pump, the temperature of the liquid is changed and the value of the liquid flow through the main pump corresponding to each temperature value is measured.
Способ осуществл ют следующим образом.The method is carried out as follows.
При заданных значени х минимальной температуры жидкости и максимальной объемной производительности входное давление уменьшают до наступлени режима запирани , а затем при посто нном его значении увеличивают температуру жидкости до получени минимальной заданной объемной производительности насоса. После зтого за счет увеличени входного давлени восстанавливают ее исходное максимальное .згачение и далее в заданном диапазоне изменени производительности неоднократно повтор ют нагрев и повьпиение входного давлени вплоть до достижени максимально заданной температуры жидкости.At specified values of the minimum fluid temperature and maximum volumetric flow rate, the inlet pressure is reduced until the onset of the locking mode, and then at a constant value, the fluid temperature is increased to obtain the minimum desired volumetric flow rate of the pump. After that, by increasing the inlet pressure, its initial maximum pressure is restored and then, in a predetermined range of capacity, the heating and penetration pressure are repeated several times until the maximum predetermined temperature of the fluid is reached.
Предлагаемый способ позвол ет избавить .с от громоздкого терморегулирующего оборудовани - холодильников, и существенно удешевить и ускорить процесс испытаний.The proposed method allows you to save on cumbersome thermostatic equipment - refrigerators, and significantly reduce the cost and speed up the testing process.
