By rubber washer and clamp nut screwing hermetic between terminal box, the incoming line with terminal box is provided with described pump head
Corresponding clip and cable wire clamp is fastened by clip, be located on described power transmission shaft between water inlet joint and the pump housing and arrange
There is shaft coupling and couplings outside lane is sealed by O-ring.
In a kind of above-mentioned submersible pump, the power transmission shaft is provided with nylon bearing and sealing with the junction of water inlet joint
Circle.
In a kind of above-mentioned submersible pump, it is located on described power transmission shaft and water dumping is provided between water inlet joint and pump head
Device.
In a kind of above-mentioned submersible pump, the outer ring of the water inlet joint is provided with grid.
In a kind of above-mentioned submersible pump, fixed with nut by flat key between described impeller and power transmission shaft, and leaf
Stator is provided with above wheel.
In a kind of above-mentioned submersible pump, the water outlet of the pump head is provided with water out adapter, on described pump head
Delivery port edge is provided with hand to climb.
In a kind of above-mentioned submersible pump, described hand is climbed to be coordinated by bearing pin and split pin and fixed.
The technique effect of this submersible pump is：Cable extension clamping is fixed by arranging clip on pump head,
Can effectively prevent cable from causing water to enter in terminal box because stretching makes line outlet go out deformation, increased the anti-of submersible pump
Aqueous energy, and the outer ring of shaft coupling is provided with O-ring, just in case the sealing ring of shaft coupling front end is old during long-time use
Change seepage, further waterproof action can be played by O-ring.
Compared with prior art, this submersible pump makes it have the more preferable advantage of water resistance by the setting of clip.
