Abstract
1. Насос (10), характеризующийся тем, что содержит импеллер (20) и корпус (50), охватывающий импеллер, у которого имеется главный канал (24), разделенный на первый канал (241) и второй канал (242) с общим впускным участком (22), ориентированным параллельно оси (А) вращения насоса и соответствующим входу в главный канал (24), причем первый канал (241) имеет радиально ориентированный первый выход (243), расположенный относительно оси (А) вращения на первом диаметре и обеспечивающий выпуск текучей среды под первым давлением, а второй канал (242) имеет радиально ориентированный второй выход (244), расположенный позади первого выхода (243) на втором диаметре, превышающем первый диаметр, и обеспечивающий выпуск текучей среды под вторым давлением, превышающим первое давление, при этом импеллер (20) и корпус (50) совместно формируют систему осевой балансировки, содержащую камеру (90), образованную между задней стороной (27) импеллера и обращенной к ней частью (57) корпуса, причем вход в камеру (90) расположен на уровне второго выхода (244).2. Насос (10) по п.1, отличающийся тем, что первый канал (241) и второй канал (242) разделены перегородкой (40), по меньшей мере участок которой расположен между первым выходом (243) и вторым выходом (244).3. Насос (10) по п.2, отличающийся тем, что перегородка (40) заходит в главный канал (24) в направлении впускного участка (22).4. Насос (10) по п.2 или 3, отличающийся тем, что наружный отрезок (48) перегородки (40), расположенный между первым выходом (243) и вторым выходом (244), снабжен динамическим уплотнением, установленным в зазоре между перегородкой и промежуточной стенкой (58) корпуса (50).5. Насос (10) по п.1, отличающийся тем, что в зазоре между передней стенкой гл�1. The pump (10), characterized in that it contains an impeller (20) and a housing (50), covering the impeller, which has a main channel (24), divided into a first channel (241) and a second channel (242) with a common inlet section (22), oriented parallel to the axis (A) of rotation of the pump and corresponding to the entrance to the main channel (24), and the first channel (241) has a radially oriented first exit (243) located relative to the axis of rotation (A) on the first diameter and providing fluid outlet under the first pressure, and the second channel (242) is radially oriented a second outlet (244) located behind the first outlet (243) on a second diameter greater than the first diameter and allowing fluid to be released at a second pressure higher than the first pressure, while the impeller (20) and the housing (50) together form an axial system balancing device containing a chamber (90) formed between the rear side (27) of the impeller and the housing part (57) facing it, the entrance to the chamber (90) being at the level of the second output (244) .2. A pump (10) according to claim 1, characterized in that the first channel (241) and the second channel (242) are separated by a partition (40), at least a portion of which is located between the first output (243) and the second output (244) .3 . A pump (10) according to claim 2, characterized in that the partition (40) enters the main channel (24) in the direction of the inlet section (22) .4. A pump (10) according to claim 2 or 3, characterized in that the outer segment (48) of the partition (40) located between the first outlet (243) and the second outlet (244) is equipped with a dynamic seal installed in the gap between the partition and the intermediate the wall (58) of the housing (50) .5. Pump (10) according to claim 1, characterized in that in the gap between the front wall of the head
