Description

Technical Field

[0001] This utility model relates to an oil pump, specifically an anti-static oil pump for new energy vehicles. Background Technology

[0002] The electric fuel pump is the "heart" of the fuel supply system in an electronic fuel injection engine. There are two ways to arrange the electric fuel pump in the fuel supply system: one is external, where the fuel pump is connected in series in the fuel line outside the fuel tank; the other is internal, where the fuel pump is installed inside the fuel tank and submerged in gasoline. Internal installation allows for better heat dissipation, lower operating noise, and a longer service life, making it more widely used. Currently, many hybrid electric vehicles still commonly use internal fuel pumps.

[0003] Most built-in fuel pumps currently have filters or filter bags installed at the fuel inlet to filter the fuel entering the pump core, thereby preventing a large amount of solid impurities in the fuel from entering the car's fuel lines and engine. When replacing the filter or filter bag, the existing fuel pump must be removed from the fuel tank, which is very inconvenient and needs to be improved. Utility Model Content

A cylindrical body 15 is fixedly connected to the bottom of the connecting block 21. The bottom end of the cylindrical body 15 is open. A filter cover 18 is threadedly connected to the bottom end of the cylindrical body 15. A first sealing gasket 19 is fitted on the outer wall of the cylindrical body 15 at the corresponding position of the filter cover 18. A connecting hole 16 is provided through the outer wall of the cylindrical body 15. Sealing rings 17 are fitted on both the upper and lower sides of the outer wall of the cylindrical body 15 at the connecting hole 16. A connecting seat 11 is fixedly provided on the outer wall of the cover 2. An insertion hole 14 is provided through the connecting seat 11.
