Also improve the usability and reliability of entire motor.
Holding tank 32, holding tank 32 and 31 coaxial line of through hole are offered in the side of inlay 3 towards 2 import of fill hole,
Diameter is adapted to the diameter of stop collar 43；After current limliting plug 4 is mounted on inlay 3, stop collar 43 be located in holding tank 32 and with appearance
The bottom wall of slot 32 received contradicts, and holding tank 32 plays the role of limit to stop collar 43, so that current limliting plug 4 and inlay 3 be made to cooperate
It is more firm, it is more smooth when passing through water flow, improve stability.
Fill hole 2 is stepped hole, including the first hole section 21, the second hole section being arranged successively from 2 import of fill hole to outlet
22 and third hole section 23, wherein the aperture of the first hole section 21 is greater than the aperture of the second hole section 22, the diameter of the second hole section 22 is big
In the aperture of third hole section 23.First hole section 21 is used to increase the size of import, facilitates outside water to flow into fill hole 2 and is mended
It fills；Second hole section 22 is that submersible motor external pressure crosses senior general's limit in order to prevent for assembling inlay 3, the setting of third hole section 23
Stream plug 4 extrudes inlay 3, is limited in current limliting plug 4 in through hole 31, plays the assembly for keeping current limliting plug 4 and inlay 3
The effect of relationship.
Filtration members 5, the stirring rod 52 Z-shape including pylon 51 and shape of filtration members 5, pylon are additionally provided in fill hole 2
51 be entrenched in the second hole section 22, positioned at inlay 3 towards the side of the first hole section 21, offer via hole along its axis on pylon 51
511, stirring rod 52 is threaded through on pylon 51 by via hole 511, and there are gaps between the two so as to outside water inflow.
When outside water flows through via hole 511, because differential pressure action can go out form vortex in via hole 511, to drive stirring rod 52
Axis around pylon 51 makees rotary motion, by impurity gear outside submersible motor, plays the role of filtering；And first hole section 21 hole
Diameter is greater than the aperture of the second hole section 22, is more likely formed vortex when making water flow to via hole 511, makes 52 rotation speed of stirring rod faster,
Improve the filter effect of filtration members 5.
