Description
Technical field
The present invention relates to fuel oil pump technical field, specially a kind of constant voltage electric fuel punp.
Background technique
Fuel pump is the technical term of automobile parts industry.It is one of the basic composition of electro jet car fuel injection system.
Effect be fuel oil is transported in fuel feed pump after being sucked out, pressurizeing in fuel tank and fuel pressure regulator cooperation establish it is certain
Fuel pressure.Fuel pump guarantees to supply lasting fuel oil to atomizer to oil distributing pipe conveying high-pressure fuel oil.
Fuel pump works in starting and engine operating, if engine stop and ignition switch are still in ON,
HFM-SFI control module closes the power supply of fuel pump, to avoid accidental ignition.
Fuel pump is made of electric motor, pressure restrictor, test valve, combustion of the electric motor real work in oil pump casing
In oil, do not have to worry, because fuel oil can lubricate and cool down fuel oil motor, fuel-displaced without any thing that can be lighted a fire in shell
Test valve is housed, pressure restrictor is located at oil pump casing on the pressure side, with the channel for leading to oil inlet at mouthful.When rotor disc spins
When, roller is pressed outward by centrifugal force, and the oil sealing that image rotation turns is the same, and rotor rotation pumps up effect, fuel oil is sucked from oil inlet, and
Fuel oil is pressed into fuel system from oil outlet, when closing oil pump, the test valve of oil outlet is closed, and prevents fuel oil from passing through fuel pump
Fuel tank is flowed back to, the fuel oil pipe pressure that test valve maintains is known as " residual pressure ".Fuel pump maximum pump oil pressure dependence is limited in pressure
The standard of device processed, if fuel pump pressure is limited more than predetermined pressure, pressure restrictor, which can open bypass, makes fuel oil flow back to fuel oil
At pump inlet.
Old-fashioned electric-spraying fuel pump structure is that brush motor drives turbulence pump to generate flow work, and existing passenger car voltage is
12V, when rectifier fault on vehicle or unstable output voltage, brush motor generates rotation speed change vulnerable to voltage fluctuation,
Cause oil pump output flow unstable, overtension more has the possibility burnt out.
