Design And Research On HY-WK Fuel Injection Pump Test Bench

Fuel injection pump assembly is usually installed in the fuel injection pump andgovernor parts together form a whole. The speed governor of diesel engine is the guaranteeand the limitation on the maximum speed, ensure that keep a certain relationship betweeninjection quantity and speed of the parts. And fuel injection pump is the diesel engine is themost important components, is seen as a "heart" of the diesel engine parts, once it’s out of theproblem can make the diesel engine work properly, the stand or fall of its performancedirectly determines the performance and fuel economy of diesel engine.Fuel injection pump test system is widely used in teaching, scientific research andproduction departments, become the key of the fuel injection pump research and manufacturelevel in China. Fuel injection pump fuel supply characteristics test (including pump sidepressure, nozzle pressure, the needle valve lift, fuel injection law, etc.) the production andresearch of fuel injection pump has important significance. Fuel injection pump test bench isa special equipment to test and adjust the fuel injection pump in the fuel injection pump playsan important role in manufacturing and maintenance. In addition, the fuel injection pump testbench is the automobile and diesel engine manufacturing and repair plant research anddevelopment, manufacture, inspection, and adjust the fuel injection pump parameters ofindispensable important equipment. One of its main purposes is to test and adjust the fuelinjection pump in different conditions of fuel injection quantity and injection interval Angleof each cylinder. Injection volume of the accuracy of measurement is to measure itsperformance and an important indicator of quality. At the same time, it also need to thespindle speed and fuel injection quantity for precise measurement, as we adjust or break animportant basis for fuel pump. At present, whether in domestic or in foreign countries, manymanufacturers have attached great importance to the design and research of fuel injectionpump test bench, and constantly use new technology, but also according to the newinternational standards to improve.This article first introduces the developing situation of the fuel injection pump testsystem, then mainly for fuel injection pump test bench a few big system (power transmission system, fuel supply system, oil system, control system, etc.) and its components, respectively,to carry on the design and selection of each part. This design using the SolidWorks3d designsoftware, the software of the virtual assembly and interference checking, and the prototypetest, prototype test and data analysis, finally, guarantee the precision of the test bench made adetailed introduction.
