The above technical purpose of the present invention is mainly solved by the following technical solutions: the pump is characterized in that the top cover body is provided with a through hole, a bolt penetrates through the through hole to form a threaded hole in the motor shell of the pump, the top cover is provided with a threaded hole, the size of the threaded hole is matched with the size of the threaded hole in the motor shell, and the corresponding bolt sequentially forms a threaded connection with the threaded hole in the top cover and the corresponding threaded hole in the motor shell, so that the top cover is fixed on the motor shell. Set up screw hole and through-hole simultaneously on the top cap, make the top cap fix on the motor casing through the bolt that passes screw hole and through-hole respectively, when needs dismantle the top cap, adopt spanner or wind to criticize, make the screw thread section on spanner and the wind criticize form the spiro union with the screw hole on the top cap, conveniently dismantle the top cap through instruments such as spanner or wind criticize, conveniently believe the inside spare part of change motor a little.
As further improvement and supplement to the above technical scheme, the utility model discloses a following technical measure: screw hole size on the top cap and dismantle the screw thread section size adaptation on spanner or the wind batch for on dismantling the top cap make things convenient for spanner or wind batch to assemble to the top cap, the power of dismantling is applyed to the top cap to the convenience, makes the convenient dismantlement of top cap. The size of the threaded hole in the top cover is also adapted to the size of the through hole in general.
The top cover is provided with at least two threaded holes which are arranged in a central symmetry manner. Under the general condition, the screw hole on the top cap is the even number, and two screw holes of central symmetry are located the diameter direction of top cap, and screw thread section (like the bolt) on spanner or the wind batch forms with the screw hole that corresponds respectively to be connected, makes spanner or wind batch connect to the top cap on, conveniently rotates spanner or wind batch, drives the top cap and rotates, dismantles the top cap that can be convenient.
Preferably, the through holes are at least two and are arranged in a central symmetry mode.
The utility model discloses beneficial effect who has: 1. set up screw hole and through-hole simultaneously on the top cap, make the top cap fix on the motor casing through the bolt that passes screw hole and through-hole respectively, when needs dismantle the top cap, adopt spanner or wind to criticize, make the screw thread section on spanner and the wind criticize form the spiro union with the screw hole on the top cap, conveniently dismantle the top cap through instruments such as spanner or wind criticize, conveniently believe the inside spare part of change motor a little. 2. The threaded hole on the top cap is even number, and two threaded holes of central symmetry are located the diameter direction of top cap, and screw thread section (like the bolt) on spanner or the wind batch forms with the threaded hole that corresponds respectively to be connected, makes spanner or wind batch connect to the top cap on, conveniently rotates spanner or wind batch, drives the top cap and rotates, dismantlement top cap that can be convenient. 3. The size of the threaded hole in the top cover is matched with the size of the threaded section on the disassembling wrench or the screwdriver, and is also matched with the size of the through hole.
