Different types of fuel pump

 

1.Electric centrifugal booster pump edit voice


In some aircraft, the electric centrifugal booster pump is used as an auxiliary fuel pump for the fuel system. The motor is usually installed on the spar corresponding to the lower position of the fuel tank, and the pump body is immersed in the fuel at the bottom of the fuel tank. Take sealing measures between the pump impeller and the motor to prevent fuel or oil vapor from leaking into the motor. When the fuel enters the pump body, the high-speed rotating impeller ejects the fuel outward in the radial direction, generating centrifugal force, increasing the fuel pressure, and delivering the fuel to the system. The rotating agitation of the pump also has the function of separating air and oil vapor from the fuel, so that the fuel supplied to the engine does not contain oil vapor.

 

2.Plunger electric fuel pump edit voice


Due to the high cost of electric centrifugal booster pumps, many small low-wing aircraft fuel systems use electric plunger pumps as auxiliary fuel pumps for the fuel system. The plunger pump is usually installed in parallel with the engine-driven diaphragm fuel pump so that they can supply fuel to the engine individually or together.
The plunger fuel pump is a pulsation pump, which consists of a solenoid coil, a plunger, a calibration spring, and two one-way valves (net 9-14). The electromagnetic coil is wound on the brass tube connecting the two oil chambers. The elastic force of the calibration spring pushes the plunger upward, and the electromagnetic force of the coil pushes the plunger downward. One one-way valve is installed in the middle of the plunger, and the other is installed in the middle of the bottom of the brass tube extension in the oil inlet cavity.

When the plunger pump is not energized, the force of the calibration spring pushes the plunger up along the brass tube, and the plunger will attract the magnet and make the contacts contact through the pivot. After being energized, the current flows through the electromagnetic wire through the contact to generate electromagnetic force, which draws the plunger downward into the coil part. At this time, the fuel in the B cavity flows upward into the plunger through the one-way valve. When the plunger moves down to the middle of the solenoid coil, the magnet will no longer be attracted, the contact will open, and the solenoid coil will be de-energized. The electromagnetic force disappears. At this time, the calibration spring pushes up the plunger, and the fuel in the C cavity is squeezed out and supplied to the engine. At the same time, the fuel from the fuel tank is pumped into the A cavity, and then into the B cavity through the bottom one-way valve, ready for the next fuel supply cycle.
If the engine receives the entire output of the pump, the pump's pulsation frequency is high; but if the engine carburetor idle valve is closed, or there is pressure between the carburetor and the pump, the pump will be in a low-speed pulsation state.

 

3.Vane fuel pump edit voice


The four steel blades slide along the radial direction of the rotor in the sliding grooves opened on the rotor. One end of the blade presses against the inner wall of the pump barrel, and the other end is in contact with the floating shaft through a spring. The internal cavity of the rotor is divided into 4 working cavities by the blade and the floating shaft. The pump barrel is fixed on the casing of the pump, and there are oil inlet and outlet ports on both sides. The power of the rotor can be driven by an engine or a motor.
When the rotor is working, it rotates clockwise. Because the pump barrel and the rotor are eccentric, the volume of each working chamber is constantly changing with the rotation of the rotor. The fuel in the fuel tank is sucked into the working chamber. When the blades turn to the outlet side, the volume of the working chamber becomes smaller, and the fuel is squeezed out to flow to the carburetor.
When the pump outlet pressure is greater than the specified value, the pressure acting on the lower surface of the pressure relief valve overcomes the spring force, pushes the pressure relief valve upwards, and guides the excess fuel from the pump outlet back to the inlet, so that the fuel supply pipe between the pump outlet and the carburetor The fuel pressure in the road is always kept within the specified value. When the vane pump fails during engine operation, as long as the inlet pressure of the pump is slightly greater than the outlet pressure, the pressure acting on the surface of the bypass valve plate overcomes the force of the thin spring and opens the bypass valve plate downward to make the fuel full. The flow goes to the carburetor of the engine.
The head of the pump is equipped with a fuel supply pressure regulating device, which can automatically adjust the fuel pressure at the pump outlet within the specified range. If the fuel pressure is abnormal when the pump is working, the pressure regulating device should be checked first, and the pressure should be corrected by the adjustment screw test method.
