Problems solved by technology

[0002] The electric fuel pump is installed in the fuel tank, soaked in the fuel, pressurizes the gasoline, and continuously pumps it into the oil supply pipeline. When it is running, its motor part is also immersed in the gasoline, and the fuel is supplied by the gasoline. The high temperature generated during its work cools down, so the fuel lamp alarms for a long time, but if it is not refueled in time, it will cause the motor part to have no gasoline to cool down, and the temperature is too high, which will cause the motor and the absorber diaphragm to burn out; The suction pipe and diaphragm are blocked; and when the oil pressure is too high, the safety valve will continue to decompress, and the electric fuel pump needs to be disassembled for inspection to find out, and the internal oil pressure cannot be visually detected to be abnormal

Embodiment 1

[0011] A high-durability electric fuel pump, including: one-way valve 1, safety valve 2, semiconductor cooling plate 3, motor 4, temperature sensor probe 5, impeller 6, oil inlet 7, filter screen 8, housing 9, sealing strip 10. Magnet 11, slot 12, inner shell 13, pump cover 14, controller 15, vane 16, pressure detection valve 17, check valve 1 is installed on the top of the housing 9, safety valve 2 is installed on one side of check valve 1, single Install the controller 15 on one side of the valve 1, install the motor 4 under the one-way valve 1, install the magnet 11 on both sides of the motor 4, install the slot 12 on the side of the magnet 11, install the sealing strip 10 on the side of the slot 12, and install the bottom of the slot 12 The pressure detection valve 17 is installed, the semiconductor cooling chip 3 is installed on the motor 4, the temperature sensing probe 5 is installed under the semiconductor cooling chip 3, the impeller 6 is installed under the motor 4, t...

Embodiment 2

[0013] When the electric fuel pump is running, the fuel is introduced into the pump from the oil inlet 7, and the filter screen 8 will filter the fuel before it enters the pump, and then the motor 4 drives the impeller 6 to rotate, and the blades 16 on the impeller 6 introduce the fuel into the one-way Valve 1 is discharged after adding a certain pressure. If there is too little fuel and the motor 4 cannot be cooled by fuel, the temperature sensing probe 5 will send a signal to the controller 15 to make the semiconductor cooling chip 3 operate to cool down the motor 4 and avoid the high temperature of the motor 4. The continuous operation under the condition will shorten the service life of the motor 4; when the car is not in use, the sealing strip 10 can be removed, and the slot 12 can be disassembled to clean the inside of the pump to avoid excessive impurities in the pump, which may cause the electric fuel pump to be damaged. The service life is greatly shortened; when check...

Abstract

The invention discloses a high-durability electric fuel pump. The high-durability electric fuel pump comprises a one-way valve, a safety valve and the like, and is characterized by further comprising a semiconductor refrigerating chip, a temperature sensing probe, a sealing strip, slots, a controller and a pressure detecting valve; the one-way valve is mounted above a shell; the safety valve is mounted on one side of the one-way valve; the controller is mounted on one side of the one-way valve; a motor is mounted below the one-way valve; magnets are mounted on two sides of the motor; and the slots are formed in one sides of the magnets. The high-durability electric fuel pump is additionally provided with the temperature sensing probe for detecting the temperature of the motor; when the temperature of the motor is too high, the controller is triggered; the semiconductor refrigerating chip is operated for cooling the motor to prevent high-temperature operation to shorten the service life; the slots can be termly dismounted to clean the internal of the electric fuel pump to prevent damage caused by excessive internal impurities; and when the electric fuel pump is checked, the pressure detecting valve can directly observe the pressure index, so that the whole electric fuel pump has no need to be dismounted for inspection, and a lot of time is saved.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to a high-durability electric fuel pump. Background technique [0002] The electric fuel pump is installed in the fuel tank, soaked in the fuel, pressurizes the gasoline, and continuously pumps it into the oil supply pipeline. When it is running, its motor part is also immersed in the gasoline, and the fuel is supplied by the gasoline. The high temperature generated during its work cools down, so the fuel lamp alarms for a long time, but if it is not refueled in time, it will cause the motor part to have no gasoline to cool down, and the temperature is too high, which will cause the motor and the absorber diaphragm to burn out; The suction pipe and diaphragm are blocked; and when the oil pressure is too high, the safety valve will continue to decompress, and the electric fuel pump needs to be disassembled and inspected to find out, and the internal oil pressure cannot be visually detected ...
