На фиг.1 представлен насос, общий вид; На фиг.2 — сечение А—А на фиг.1; на фиг.З — сечение Б—Б на фиг.1.Figure 1 presents the pump, a General view; In Fig.2 - section a — a in Fig.1; in Fig.Z - section B — B in Fig.1.

Насос содержит корпус 1 с впускным и ¹⁰выпускным патрубками 2 и 3 и установленные в корпусе 1 статор 4 электродвигателя 5 с обмоткой 6 и ротор 7, последний выполнен в виде беличьего колеса с радиальными каналами 8, а на внутренней _f5поверхности 9 статора 4 выполнены продольные пазы 10. Каналы 8 выполнены в виде продольных пазов по всей длине ротора Ί и закрыты поперечной перегородкой 11 со стороны выпускного патрубка 3, а пазы 10 статора 4 перекрыты приливами 12 со сторо- 20 ны впускного патрубка 2. Каналы 8 выполнены без нарушения беличьего колеса.The pump comprises a housing 1 with an inlet and ¹⁰ outlet pipes 2 and 3 and a stator 4 of an electric motor 5 with a winding 6 and a rotor 7 installed in the housing 1, the latter made in the form of a squirrel wheel with radial channels 8, and longitudinal ones are made on the inner _{f5 of the} surface 9 of the stator 4 grooves 10. The channels 8 are made in the form of longitudinal grooves along the entire length of the rotor Ί and are closed by a transverse partition 11 from the side of the outlet pipe 3, and the grooves 10 of the stator 4 are blocked by tides 12 from the side of the inlet pipe 2. The channels 8 are made without breaking the squirrel wheel .

Насос работает следующим образом.The pump operates as follows.

При подаче напряжения на обмотку 6 статора 4 электродвигателя 5 создается вращающееся магнитное поле, приводящее во вращение ротор 7. Перекачиваемая жидкость из впускного патрубка 2 корпуса 1 попадает в каналы 8, в которых под дей ствием центробежных сил отбрасывается на периферию к пазам 10 внутренней поверхности 9 статора 4, затем отводится к выпускному патрубку 3. Перегородки 11 способствуют радиальному течению жидкости в каналах 8, что позволяет повысить напор насоса за счет использования центробежных сил по всей длине тела ротора 7. Приливы 12 предотвращают обратный переток жидкости.When voltage is applied to the winding 6 of the stator 4 of the electric motor 5, a rotating magnetic field is created, which drives the rotor 7. The pumped liquid from the inlet pipe 2 of the housing 1 enters the channels 8, in which, under the action of centrifugal forces, it is discarded to the grooves 10 of the inner surface 9 stator 4, then diverted to the exhaust pipe 3. The baffles 11 contribute to the radial flow of fluid in the channels 8, which allows to increase the pressure of the pump through the use of centrifugal forces along the entire length of the body of the rotor 7. Tides 12 prevent backflow of fluid.

Кроме того, изобретение позволяет уменьшить габариты и массу насоса вследствие использования тела ротора в качестве рабочего колеса, а также вследствие хорошего охлаждения увеличить удельную мощность привода.In addition, the invention allows to reduce the dimensions and weight of the pump due to the use of the rotor body as an impeller, as well as due to good cooling, increase the specific power of the drive.
