Problems solved by technology
[0004] The fuel main pipe testing machine has the following problems in the process of testing the fuel main pipe: when the existing testing machines test the tightness of the fuel main pipe and the oil outlet effect of the nozzle, many of them cannot intuitively see the problem of the fuel main pipe, and it is necessary to use sophisticated instruments to carry out data analysis. analysis, the test cost is high; the fuel main pipe test needs to be clamped and fixed, and the existing clamping mechanism is cumbersome to operate when clamping the fuel main pipe

The invention relates to the technical field of fuel manifold testing, in particular to an online testing machine of a fuel manifold, which comprises a testing frame, a clamping mechanism and a testing mechanism, the testing frame is a rectangular shell structure with an opening at the upper end, and the testing mechanism and the clamping mechanism are respectively arranged at the left side and the right side in the testing frame. According to the invention, the sealing performance of the fuel manifold and the oil outlet effect of the nozzle can be tested through the sealing test part and the oil outlet test assembly, and the sealing performance test mainly comprises the steps of introducing gas into the fuel manifold soaked in water, and synchronously observing whether bubbles exist in the water so as to judge the sealing performance of the fuel manifold. The oil outlet effect of the nozzle is mainly analyzed by observing the oil outlet effect of the nozzle through the transparent testing circular cover, and meanwhile whether the oil outlet amount of the nozzle is qualified or not is judged according to the amount of fuel oil sprayed out of the nozzle and collected by the measuring cylinder with the scale strip.
Description
technical field [0001] The invention relates to the technical field of fuel main pipe testing, in particular to an online testing machine for fuel main pipes. Background technique [0002] The fuel manifold is an important component of the fuel supply system of the engine combustion chamber. Its main function is to deliver fuel to the nozzles evenly. As the power source of the engine, the fuel manifold is very important for its performance and reliability. [0003] Such as Figure 10 As shown in the figure, the fuel main pipe is connected with multiple nozzles along its length direction, the two ends of the fuel main pipe are welded with connecting pieces, and the upper and lower ends of the connecting piece are provided with round holes, and one end of the fuel main pipe is provided with an inlet. The fuel main pipe needs to have good sealing performance. To avoid oil leakage from the fuel main pipe, at the same time, whether the fuel injection effect of the nozzles connect...
