Fuel Pump The Structure Of The Form
Aug 30, 2017

What is the structure of the fuel pump? In fact, the fuel pump as a professional auto parts industry, a term, it is EFI fuel injection system, one of the basic components. The role is to take fuel from the fuel tank, pressurized and transported to the oil supply pipe, and fuel pressure regulator with the establishment of a certain fuel pressure.

structure type:

Fuel pump by the electric motor, pressure limiter, check valve composition, the electric motor actually work in the oil pump shell fuel, do not worry, because the shell does not have anything to ignite the fuel, the fuel can lubricate and cool the fuel motor, Is equipped with a check valve, the pressure limiter is located on the pressure side of the oil pump housing, with a passage leading to the inlet port.


ZYB ignition supercharged fuel pump is suitable for conveying diesel oil, heavy oil, residue oil, fuel oil and other media, especially for the road and bridge engineering mixing station in the fuel pump, is to replace the ideal product of imported products.

ZYB supercharged fuel pump is not suitable for conveying highly volatile or low flash point of the liquid, such as ammonia, benzene and so on.

working principle:

When the rotor disc rotates, the roller is centrifugal force outward pressure, like the rotating oil seal, the rotor rotation, pump function, from the inlet into the fuel, and the fuel from the oil into the fuel system, when the oil pump off , The oil port of the check valve closed to prevent fuel flow through the fuel pump back to the tank, check the valve to maintain the fuel pipe pressure is called "residual pressure."
