Problems solved by technology

[0002] The EFI fuel pump is an important accessory for the gasoline pump to extract gasoline from the fuel tank and supply it to the engine. If the existing EFI fuel pump is used for a long time, if the internal pressure is not detected, the internal pressure may be insufficient, causing the car to generate Failure, if there is a sudden failure and parking on the road, it is likely to cause a traffic accident and cause danger. Therefore, it is necessary to detect it in time when the power of the electric fuel pump is found to be insufficient to avoid danger.

Abstract

The invention discloses an electronic injection fuel pump detection system based on negative pressure. The system comprises a mounting plate, wherein four support columns are mounted at the top end of one side of the mounting plate, a support plate is connected to the top end of each support column, an open slot is formed in the middle of the bottom end of the mounting plate, a control panel is mounted on the front surface of the support plate, and a negative pressure pump is mounted on one side of the top end of the support plate. According to the electronic injection fuel pump detection system based on the negative pressure, change of pressure in an electric fuel pump can be detected by means of the negative pressure pump and a vacuum tank which are arranged, pressure in an electronic injection fuel pump can be detected by means of the arranged negative pressure pump, extruded gas can be collected by means of the arranged vacuum tank, a pressure testing circuit detects change of gas and displays the change on the control panel, the electronic injection fuel pump can form different angles with a horizontal plane through a rotating plate and a push rod motor which are arranged, and the working performance of the electronic injection fuel pump can be detected by simulating the process that an automobile goes uphill or horizontally runs or goes downhill or the like.

Description

technical field [0001] The invention relates to the field of electric fuel injection fuel pumps, in particular to a detection system for electric fuel injection fuel pumps based on negative pressure. Background technique [0002] The EFI fuel pump is an important accessory for the gasoline pump to extract gasoline from the fuel tank and supply it to the engine. If the existing EFI fuel pump is used for a long time, if the internal pressure is not detected, the internal pressure may be insufficient, causing the car to generate Failure, if there is a sudden breakdown on the road, it is likely to cause a traffic accident and cause danger. Therefore, it is necessary to detect it in time when the power of the electric fuel pump is found to be insufficient to avoid danger. [0003] Existing electronic injection fuel pumps often just fix the fuel pump on a horizontal or vertical position when testing, and carry out a pressure test on its fuel injection, thereby detecting whether it...
