Abstract

Заглибний електронасос стосується продукції машинобудування, зокрема агрегатів для подачі продуктів, обладнаних відцентровими електронасосами. Заглибний електронасос містить корпус 1, в якому розташований відцентровий насос 2 з електродвигуном 3, що містить водозахищений статор 4 і ротор 5. Порожнина електродвигуна 3 заповнена сумішшю, компонентами якої є вода з упорядкованою молекулярною структурою і необроблений гліцерин, при співвідношенні "гліцерин-вода" в межах від 0,4:0,6 до 0,6:0,4. Електродвигун 3 містить також компенсаційну камеру 7, розташовану з боку хвостової частини вала 8 ротора 5, яка сполучена з порожниною електродвигуна через систему каналів 9'-9". Компенсаційна камера 7 призначена для збирання зазначеної суміші, що витікає з порожнини електродвигуна 3. Така конструкція дозволяє відвернути перегрівання і підвищити рівень вибухозахищеності електронасоса. Зворотний клапан на виході насоса забезпечую сприятливі умови для роботи електронасоса при понижених температурах навколишнього середовища, у результаті чого підвищується загальна надійність електронасоса.Submersible electric pump refers to mechanical engineering products, in particular units for feeding products equipped with centrifugal electric pumps. Submersible electric pump contains a housing 1, which houses a centrifugal pump 2 with an electric motor 3, containing a waterproof stator 4 and a rotor 5. The cavity of the electric motor 3 is filled with a mixture whose components are water with ordered molecular structure and untreated glycerin in the range from 0.4: 0.6 to 0.6: 0.4. The motor 3 also includes a compensation chamber 7 located on the tail side of the rotor shaft 8, which is connected to the motor cavity through a system of channels 9'-9 ". Compensation chamber 7 is designed to collect this mixture flowing from the cavity of the motor 3. This design The non-return valve at the pump outlet provides favorable conditions for the operation of the electric pump at low ambient temperatures, which increases the overall reliability of the electric pump.
