Diesel Injector Fuel Injector 0445120267 Bosch for Ford Cargo 1723 / 2423 / 2429 / 2623 / 2629 6.7L Isb L6 Engine

1. Design idea of nozzle flow detection equipment

In the current domestic standards, there are clear regulations and requirements on the test method of the total oil quantity of the nozzle and the deviation value of the flow, but there is no requirement on the flow rate of each nozzle. In order to further improve the production of the current conditions of the nozzle, there is a machine to detect the difference of the flow rate of each nozzle accurately and quickly, and timely discover the difference in the processing of the nozzle In order to provide testing means for further improving product quality, we develop the reaction point of the attack. Under the premise of R1DBR suburban part a flow detection requirements, the structure is simplified as far as possible, and the structure and parts with high reliability are adopted.

2. Main structure and working principle of the equipment

The testing equipment is composed of mechanical system, measurement system and control and display system.

(1) Mechanical system. The mechanical system is mainly composed of frame, oil supply system, quick clamping mechanism, acquisition device and so on. The framework design mainly considers the integrity, easy internal maintenance, as well as beautiful appearance, reasonable layout, easy to operate. The function of the oil supply system is to provide a stable measuring oil that is consistent with the actual operating oil of the injector. The main oil circuit is composed of oil storage tank, filter, oil pump, accumulator and pressure regulating valve, etc. The oil pressure is continuously adjustable in the range of 0~0.6MPa. By heating and cooling equipment, the oil temperature can be kept in the range of 40 ℃ 2℃. The quick clamping mechanism is composed of turning bracket, oil passage body, quick clamping nut, etc. The oil passage body is made of brass and is mainly used for placing magnetic steel to avoid the influence of magnetic force lines.
