The invention provides a novel passenger car brushless alcohol pump, and belongs to the technical field of pumps. The novel passenger car brushless alcohol pump comprises a pole shell, an oil outlet base, a stator assembly, a rotor assembly, a pump chamber, a worm wheel and a pump cover; a controller is externally arranged outside the pole shell, connected through a wire and sealed by glue filling, the problem that control fails is avoided, a wiring harness and a sealing component arranged on the oil outlet base, an earth tag and a first electrode slice are of an integrated injection molding structure, a coil of the stator assembly, a second electrode slice and a plastic-coated layer are of an integrated structure and coat an insulation layer, and the plastic-coated layer, the sealing component and the oil outlet base are all sealed by a sealing gasket, so that the joint of the first electrode slice and the second electrode slice are completely isolated from methyl alcohol; in addition, a clad layer is arranged on the surface of the pole shell, and methyl alcohol resistance sealing solutions are arranged on the surfaces of the pump chamber and the pump cover; in this way, a power-on metal structure and a part of a non-power-on metal structure are isolated, methyl alcohol corrosion is avoided, and the service life of the pump is prolonged.
Description
technical field [0001] The invention relates to the technical field of pumps, in particular to a novel brushless alcohol pump for passenger cars. Background technique [0002] With the development and utilization of energy, methanol fuel vehicles have been developed to a certain extent, and the alcohol fuel suitable for fuel pumps needs to meet the requirements of ordinary gasoline. However, methanol, as an alcohol fuel, has strong swelling and corrosion properties, and is highly corrosive to alloy metals, which affects the structural stability and service life of the pump body. Moreover, methanol also has weak conductivity, which makes the The galvanic alloy metal immersed in it causes galvanic corrosion. [0003] Currently, fuel pumps on the market include brushed fuel pumps and brushless fuel pumps. Due to the limitation of the structure of the existing brushed fuel pump, its brush braids, connectors and other structures are exposed to immersion in methanol, resulting i...
