Abstract

Przedmiotem wynalazku jest silnik elektryczny do pomp z zamknietym ukladem chlodzenia ciecza. Zamkniety uklad chlodzenia sklada sie z plaszcza (5) zbudowanego z dwóch oddzielonych od siebie scianek (6) i (7) miedzy którymi znajdujaca sie przestrzen jest wypelniona ciecza chlodzaca odbierajaca cieplo silnika. Plaszcz (5) poprzez kanal doplywowy (8) i komore wyrównawcza (9) laczy sie z komora ssawna (10), w której znajduje sie wieloplatkowy wirnik obiegowy (11) o przeplywie osiowym. Jest on umieszczony pomiedzy uszczelnieniami. W wirniku (11) stosunek srednicy piasty wirnika dp do srednicy zewnetrznej wirnika do zawiera sie w przedziale od 0,3 do 0,99 oraz liczba lopatek (12) wynosi od 2 od 50 sztuk, zas wyróznik szybkobieznosci jest ? 800. Poczatek sciany przekazujacej cieplo (13) do pompowanego medium wchodzacej w sklad wymiennika ciepla skladajacego sie z kanalu wymiennika ciepla (14) i komory wymiennika ciepla (15) umieszczony jest od wirnika (11) w odleglosci wynoszacej od 0 do 10 srednic zewnetrznych wirnika do. Wysokosc h kanalu wymiennika ciepla (14), który odbiera nagrzana ciecz chlodzaca i komory wymiennika ciepla (15) jest równa wynikowi dzialania: h= [0,25, 6]*(do-dp)÷2, przy czym [0,25, 6] oznacza zamkniety zbiór mieszczacy sie w przedziale od 0,25 do 6, zas do oznacza srednice zewnetrzna wirnika, a dp - srednice piasty wirnika.The subject of the invention is an electric motor for pumps with a closed liquid cooling system. The closed cooling system consists of a jacket (5) made of two separate walls (6) and (7), between which the space is filled with a cooling liquid that receives the engine heat. The mantle (5) connects through the inlet channel (8) and the equalizing chamber (9) with the suction chamber (10) in which there is a multi-blade circulating rotor (11) with axial flow. It is placed between the seals. In the rotor (11), the ratio of the rotor hub diameter dp to the outer rotor diameter to is in the range from 0.3 to 0.99 and the number of blades (12) is from 2 to 50 pieces, while the discriminant of the speed is? 800. The beginning of the heat transferring wall (13) to the pumped medium consisting of a heat exchanger channel consisting of a heat exchanger channel (14) and a heat exchanger chamber (15) is located from the rotor (11) at a distance of 0 to 10 impeller outer diameters down. The height h of the heat exchanger channel (14), which receives the heated cooling liquid and the heat exchanger chambers (15), is equal to the result of the operation: h = [0.25, 6] * (do-dp) ÷ 2, where [0.25 , 6] means a closed set ranging from 0.25 to 6, while do means the outer diameter of the rotor, and dp - the diameter of the rotor hub.
