Pump - Fuel Pump Introduction to the working principle

Fuel pump works: Introduction to the working principle of the fuel pump (Asian Fluid Network) Fuel pump works - currently used in the fuel tank mounted in the fuel pump. Fuel pump is a turbo pump, pressure relief valve, residual pressure check valve. Turbine pump is driven by the motor impeller, sucked out of the fuel from the tank, the motor needs to be cooled and lubricated by fuel, if the amount of oil reduction may make the motor burn; relief valve role is when the pump outlet pressure value is, the relief valve Will open and unload excess oil Residual pressure check valve's role is to stop working when the pump, the valve is closed, the residual oil pressure in order to restart the pump is controlled by the engine speed signal switch (when the engine does not turn the fuel Pump stopped working). Related pump working principle: Rotary oil pump working principle Rotary oil pump working principle: When the inner rotor rotates, the outer rotor is driven to rotate. As the rotor tooth profile is designed so that the rotor to any position, the inner and outer rotor tooth profile of each tooth can always maintain a point contact with each other state; so, between the inner and outer rotor Form four working chambers. When a working chamber is rotated from the suction chamber, the volume increases to generate a vacuum, and oil is drawn into the working chamber through the oil inlet hole. As the inner and outer rotors continue to rotate, the working chamber is rotated to the position where the pressure chamber is communicated , The smaller the volume, the hydraulic pressure increases, the oil pressure from the oil hole into the lubricating oil in the channel. Rotor pump compact structure, uniform oil supply, vacuum suction high, large pump oil, widely used in the car engine. Such as: Xiali tj7100, Japan mazda323, honda and other car engines are used rotor-type oil pump.
