The purpose of the utility model can be realized by the following technical proposal: the pump cover of the single-hole outlet submersible pump comprises a pump cover body and is characterized in that a single outlet hole is formed in the top of the pump cover body, a sealing element and a fastening element are sequentially arranged at the outlet hole, the bottom of the sealing element protrudes downwards to form a tensioning part matched with the outlet hole in structure, the tensioning part is in interference fit with the outlet hole, two sealing holes are formed in the top of the sealing element in parallel, the tensioning part and the sealing holes are communicated with each other in the inner part, a cavity matched with the upper structure of the sealing element is formed in the fastening element, the volume of the cavity is smaller than that of the upper structure of the sealing element, and locking holes matched with the positions of the sealing holes are formed in the cavity.
The pump cover of the single-hole outlet submersible pump has the technical effects that: the main cable and the floating ball cable respectively penetrate through the two sealing holes of the sealing element and penetrate out of the tensioning portion below the sealing element, the main cable and the floating ball cable are connected with a submersible pump motor through the wire outlet hole in the pump cover body, the tensioning portion presses downwards into the wire outlet hole to fix the two cables through internal contraction to prevent movement, then the fastening element is pressed downwards to be fixed with the pump cover body, and the cavity inside the fastening element is smaller than the size of the upper structure of the sealing element, so that the sealing holes are contracted inwards through the locking holes to be in tight contact with the outer wall of the cable to achieve sealing.
In the pump cover of the single-hole outlet submersible pump, the outer part of the pump cover body, which is positioned on the outlet hole, protrudes upwards to form a step structure, and the upper end surface of the step structure is a rhombic plane with the same shape as the bottom surface of the sealing element.
In the pump cover of the single-hole outlet submersible pump, the left end and the right end of the step structure are provided with screw holes, and the sealing element and the fastening element are provided with through holes corresponding to the two screw holes.
In the pump cover of the single-hole outgoing line submersible pump, the sealing element is made of rubber.
In the pump cover of the single-hole outlet submersible pump, the pump cover is made of aluminum alloy.
Compared with the prior art, the pump cover of the single-hole outlet submersible pump is used for simultaneously penetrating through the main cable and the floating ball cable by arranging the single outlet hole, and the two sealing holes of the sealing element are locked and sealed with the outside of the cable through the fastening piece, so that the pump cover has the advantages of higher structural strength and more convenient forming.
