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 a negative pressure-based electronic fuel pump detection system, which includes a mounting plate, four supporting columns are installed on the top of one side of the mounting plate, the top of each supporting column is connected with a supporting plate, and the bottom of the mounting plate is There is a slot in the middle, a control board is installed on the front of the support plate, and a negative pressure pump is installed on one side of the top of the support plate. The negative pressure-based EFI fuel pump detection system of the present invention, through the negative pressure provided The pump and vacuum tank can detect the change of pressure in the electric fuel pump, and the pressure inside the electric fuel pump can be detected by the negative pressure pump, and the extruded gas can be collected by the vacuum tank. The unique pressure test circuit detects the change of gas and displays it on the control board. Through the rotating plate and the push rod motor, the electronic injection fuel pump can present different angles with the horizontal plane, which can simulate the car driving uphill, horizontally or Downhill and other processes to test the performance of the electronic fuel pump.

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...
