The invention discloses a high-stability isolation type electric water pump. The electric water pump comprises a pump body, a mounting base, a fixing base, an upper fixing ring, a fixing bolt, two upper fixing assemblies, multiple damping springs, multiple positioning columns and multiple positioning nuts, wherein the top end of the mounting base is connected to the bottom ends of the multiple damping springs, the top ends of the multiple damping springs are all connected to the bottom end of the fixing base, the top ends of the multiple positioning columns penetrate through the multiple damping springs correspondingly to be connected to the bottom end of the fixing base, the bottom ends of the multiple positioning columns penetrate through the mounting base to be connected to the multiple positioning nuts in a threaded mode correspondingly, one end of the upper fixing ring is connected to the fixing base in a rotating mode, a fixing sheet is arranged at the right end of the upper fixing ring, the bottom end of the fixing bolt penetrates through the fixing sheet to be connected to a threaded mounting hole in the fixing base in a threaded mode, and the two upper fixing assemblies are symmetrically arranged on the upper fixing ring.
Description
technical field [0001] The invention relates to the technical field of electric water pumps, in particular to a highly stable isolated electric water pump. Background technique [0002] Automotive water pumps are devices used to transport engine coolant in vehicles. According to the driving mode, they can be divided into mechanical water pumps and electric water pumps. Electric water pumps can be divided into brush electric water pumps and brushless electric water pumps according to whether they have carbon brushes. The mechanical water pump must be driven by the engine, and the speed of the water pump has a fixed ratio to the engine speed, which cannot meet the heat dissipation requirements under low-speed and heavy-load conditions, and cannot meet the cooling requirements of the main drive motor and other components of new energy vehicles when the engine stops working, and The water supply requirements on the RV; the brush electric water pump has poor anti-electromagnetic ...
