Abstract
The utility model relates to a submersible pump, which is composed of a pump cover, a pump body, an electric motor and a worm shell, wherein, a water pump impeller, a net cover and a water outlet connecting opening are arranged on the worm shell. The auxiliary of the electric motor of the water pump is connected with a working capacitor in series. The working capacitor is connected with a starting capacitor and a centrifugal switch in parallel. Compared with the existing submersible pump, the utility model has the advantages of small volume, light weight, low cost and power consumption saving. The utility model is especially used as the water pumping devices of field irrigation, civil building, family life, etc.
Description
The utility model belongs to a kind of water plug, particularly a kind of submersible pump.
Submersible pump is a kind of field irrigation that is widely used in, the water plug of engineering construction and family life etc.Have only a starting capacitance in the circuit of existing its motor of submersible pump, when submersible pump was worked, this electric capacity and the secondary winding that is in series with it were not all worked, and this reduces the submersible pump working efficiency.Simultaneously, present submersible pump also exists the deficiency that volume is big, weight is heavier, cost is high, power consumption is big.
Task of the present utility model is at the existing above-mentioned deficiency of existing submersible pump, and the submersible pump that a kind of efficient height, volume are little, in light weight, power consumption is economized, cost is low is provided.
Task of the present utility model is finished in the following way: mutual capacitance of series connection on the secondary winding of existing motor for submerged pump, this mutual capacitance is in parallel with starting capacitance and centrifugal switch.Simultaneously, stator and rotor length in the motor on the existing submersible pump are all shortened 1/3rd to sixth.
The utility model is compared with existing submersible pump, has the advantages that volume is little, in light weight, cost is low, power consumption is economized, efficient is high.The utility model is particularly suitable as a kind of field irrigation, the water plug of engineering construction and family life etc.
