Claims (4)

1. Индуктор для насоса с большой всасывающей мощностью, включающий картер (124), окружающий ротор индуктора (123), имеющий множество лопаток (136), которые образуют зазор (J11) с картером (124), отличающийся тем, что зазор (J12) между периферической частью лопаток (136) и картером (124) выполнен увеличенным и имеет величину, превышающую величину нормального зазора (J11), в области, которая одновременно простирается в первой цилиндрической части (127) внутренней стенки картера (124) выше ротора индуктора (123) и на участке (127А) внутренней стенки картера (124), прилегающей к этой первой цилиндрической части (127) и распространяющейся выше части ротора индуктора (123) на расстоянии (d11), начиная с переднего края лопаток (136), ротора индуктора (123), и тем, что соотношение между увеличенным зазором (J12) и зазором нормальной величины (J11) выше 10.1. An inductor for a pump with high suction power, comprising a crankcase (124), a surrounding rotor of the inductor (123), having a plurality of vanes (136) that form a gap (J11) with a crankcase (124), characterized in that the gap (J12) between the peripheral part of the blades (136) and the crankcase (124) is made larger and has a value greater than the normal clearance (J11), in the region that simultaneously extends in the first cylindrical part (127) of the inner wall of the crankcase (124) above the inductor rotor (123 ) and on the section (127A) of the inner wall of the crankcase (124) adjacent to this first cylindrical part (127) and extending above the part of the inductor rotor (123) at a distance (d11), starting from the front edge of the blades (136), inductor rotor (123), and the ratio between the increased clearance (J12) and a clearance of normal value (J11) above 10. 2. Индуктор по п.1, отличающийся тем, что зазор нормальной величины составляет 0,4 - 1% радиуса периферической части лопаток индуктора. 2. The inductor according to claim 1, characterized in that the gap of normal size is 0.4 - 1% of the radius of the peripheral part of the blades of the inductor. 3. Индуктор по п.1 или 2, отличающийся тем, что зазор нормальной величины (J11) составляет 0,4 - 0,9 мм, а увеличенный зазор (J12) составляет 5 - 10 мм. 3. The inductor according to claim 1 or 2, characterized in that the normal clearance (J11) is 0.4-0.9 mm and the increased clearance (J12) is 5-10 mm. 4. Индуктор по одному из пп. 1-3, отличающийся тем, что расстояние (d11), простирающееся вдоль оси ротора индуктора (23), начиная с передней кромки лопаток (136), составляет 15 - 20% осевой длины лопаток индуктора. 4. The inductor according to one of paragraphs. 1-3, characterized in that the distance (d11), extending along the axis of the rotor of the inductor (23), starting from the leading edge of the blades (136), is 15 - 20% of the axial length of the blades of the inductor.
