Embodiment
As Fig. 1, Fig. 2, shown in Figure 3.
A kind of electric pump of water cycle cooling motor mainly is made up of motor 2, cooling water inlet pipe 3, step 4, mechanical seal body 5, impeller 6, the pump housing 7 of: water proof cover 1, band cooling water circulation port.
A kind of electric pump of water cycle cooling motor, comprise: water proof cover 1, the motor 2 of band cooling water circulation port, cooling water inlet pipe 3, step 4, mechanical seal body 5, impeller 6, the pump housing 7, step 4, mechanical seal body 5, impeller 6 is installed in the rotating shaft of the motor 2 of being with the cooling water circulation port, mechanical seal body 5 is connected with step 4, cooling water inlet pipe 3 is installed on the outside of motor 2 housings of band cooling water circulation port, and be connected with the water inlet rectangular hole 11 of step 4, water proof cover 1 is set in outside the motor 2 of band cooling water circulation port, water proof cover 1, the motor 2 of band cooling water circulation port, cooling water inlet pipe 3, step 4, mechanical seal body 5, impeller 6 is worked in coordination back and the pump housing 7 connections is installed, impeller 6 is positioned at the pump housing 7, cooling water inlet pipe 3 sealings insert in the water intake of the circulating water of step 4 flanges, the symmetry place of the water intake of step 4 flange circulating waters is cast with the water inlet rectangular hole 11 of recirculated cooling water, the symmetry place of the water outlet of step 4 flange circulating waters is cast with the water outlet rectangular hole 9 of recirculated cooling water, mechanical seal cover 5 flanges are cast with the water outlet of recirculated cooling water and water outlet the rectangular hole 9 corresponding and big or small identical rectangular holes of step 4 flange recirculated cooling waters, and are provided with the gradient refluxing chamber 10 of band gradient below this hole.
Gap between the impeller 6 and the pump housing 7 is 0.5 millimeter.
Constitute cooling chamber 8 between the motor 2 of water proof cover 1 and band cooling water circulation port.
The housing of the motor 2 of band cooling water circulation port is provided with several cooling water circulation ports.
As shown in Figure 1, the electric pump structure of this water cycle cooling motor is as follows: this electric pump is made up of water proof cover 1, the motor 2 of being with the cooling water circulation port, cooling water inlet pipe 3, step 4, mechanical seal body 5, impeller 6, the pump housing 7 etc.
