Products detail

Introduction

The fuel pump delivers high-pressure fuel to the fuel distribution pipe to ensure continuous fuel supply to the fuel injection nozzle.
The fuel pump consists of an electric motor, a pressure limiter, and a check valve. The electric motor actually works in the fuel in the fuel pump housing. Don’t worry, because there is nothing in the housing that can be ignited. The fuel can lubricate and cool the fuel motor. There is a check valve, and the pressure limiter is located on the pressure side of the oil pump housing, with a passage leading to the oil inlet.
The ZYB ignition booster fuel pump is suitable for conveying diesel, heavy oil, residual oil, fuel oil and other media, especially suitable for the fuel pump of the burner in the road and bridge engineering mixing station. It is an ideal product to replace imported products. The ZYB booster fuel pump is not suitable for transporting highly volatile or low flash point liquids, such as ammonia and benzene.
When the rotor disc rotates, the roller is pressed outward by centrifugal force. Like a rotating oil seal, the rotor rotates and the pump works. It sucks in fuel from the oil inlet and presses the fuel into the fuel system from the oil outlet. When the oil pump is turned off , The check valve at the fuel outlet is closed to prevent fuel from flowing back to the tank through the fuel pump. The fuel pipe pressure maintained by the check valve is called "residual pressure".
The maximum pump pressure of the fuel pump depends on the standard of the pressure limiter. If the pressure of the fuel pump exceeds the predetermined pressure limit, the pressure limiter will open the bypass to allow the fuel to flow back to the inlet of the fuel pump.

Plunger electric fuel pump

Due to the high cost of electric centrifugal booster pumps, many small low-wing monoplane 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 drawn into the A cavity, and then enters the B cavity through the bottom one-way valve, ready for the next fuel supply cycle.
If the engine receives the full 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.
