Abstract

The invention discloses a portable universal high-lift self-priming water pump which comprises a pump body, a motor shell, a water pump impeller and a motor, wherein the motor is provide with a motor rotor shaft along the axial direction of the motor shell; one end of the motor rotor shaft is fixed on the motor shell through a tail bearing, and the other end of the motor rotor shaft is fixed on a series-excited motor sealing end cover through a front bearing; a motor commutator, a motor rotor magnetic valve, a motor radiating blade, a sealing gasket and a water pump impeller are sequentially arranged on the motor rotor shaft from right to left; the end, at which the water pump impeller is arranged, of the motor is fixed on the pump body after the motor and the motor shell are mounted. According to the water pump, a series-excited motor is adopted, so that the water pump is high in working efficiency and suitable for being used in multiple places, and can be safely and reliably used.

Description

technical field [0001] The invention relates to a centrifugal pump, in particular to a portable high-lift self-priming water pump. Background technique [0002] At present, most of the centrifugal pumps on the market use ordinary motors, which have low working efficiency and small water output; traditional water pumps have complex structures, large volumes and heavy weights, poor portability, and limited use occasions; The pressure in the body is relatively high, and ordinary water pumps sold on the market do not have additional protection measures for this, which brings potential safety hazards to users. Contents of the invention [0003] Purpose of the invention: In order to enhance the safety of the water pump during use and improve the working efficiency of the water pump, the present invention provides a portable high-lift self-priming water pump. [0004] Technical scheme: in order to achieve the above-mentioned purpose of the invention, the technical scheme adopted...
