Description
(5М СПОСОБ ЗАПУСКА ЦЕИТРОБЕЙНОГО НАСОСНОГО АГРЕГАТА(5M METHOD FOR LAUNCHING A CEITROBEAN PUMPING ASSEMBLY
II
Изобретение отйоситс к области энергетики и может быть использовано при эксплуатации самовсасывающих центробежных насосных агрегатов.The invention relates to the field of energy and can be used in the operation of self-priming centrifugal pumping units.
Известен способ запуска центробежного насосного агрегата, включающий заполнение всасывающей полости насоса жидкостью путем отсоса из нее воздуха 13.A known method of starting a centrifugal pumping unit, including filling the suction cavity of the pump with liquid by sucking air from it 13.
Недостатком известного способа вл етс большое врем заполнени всасывающей линии жидкостью, что обусловлено небольшой объемной подачей воздуха, которую способен создать водокольцевой насос.A disadvantage of the known method is the large filling time of the suction line with liquid, which is caused by the small volumetric air supply that the water ring pump is capable of creating.
Цель изобретени - ускорение запуска .The purpose of the invention is to accelerate the launch.
.Указанна цель достигаетс тем, что при заполнении всасывающей полости рабочее колесо насоса вращают с частотой, превышающей рабочую частоту вращени , а по заполнении всасывающей полости жидкостью частоту вращени уменьшают до рабочей.The above objective is achieved by rotating the pump impeller at a frequency exceeding the operating frequency when filling the suction cavity, and when the liquid is filled with the suction cavity, the rotation frequency is reduced to the working one.
На чертеже изображен центробежный насос, реализующий предлагаемый способ.The drawing shows a centrifugal pump that implements the proposed method.
Центробежный насосный агрегат с электродвигателем 1 содержит корпус 2 с всасывающей -полостью 3, установленное в корпусе 2 рабочее колесо k, причем во всасывающей полости 3 установлен датчик 5 среды, а на электродвигателе 1 размещено устройство 6, The centrifugal pumping unit with an electric motor 1 comprises a housing 2 with a suction cavity, 3, an impeller k installed in the housing 2, and a sensor 5 of the medium is mounted in the suction cavity 3, and a device 6 is placed on the electric motor 1,
10 измен ющее частоту вращени ротора электродвигател 1, подключенное к датчику 5 среды.10 which changes the frequency of rotation of the rotor of the electric motor 1 connected to the sensor 5 of the medium.
Способ запуска центробежного насосного агрегата включает заполнение The method of starting the centrifugal pumping unit includes filling
ts всасывающей полости 3 насоса жидкостью путем отсоса из нее воздуха, причем при заполнении всасывающей полости 3 когда датчик 5 среды показывает наличие воздуха, рабочее ts the suction cavity 3 of the pump with liquid by sucking air out of it, and when filling the suction cavity 3 when the medium sensor 5 detects the presence of air, the operating
20 колесо k насоса вращают с помощью устройства 6 с частотой, превышающей рабочую частоту вращени , а по заполнении всасывающей полости 320, the pump wheel k is rotated using the device 6 with a frequency exceeding the operating frequency of rotation, and after filling the suction cavity 3
