我部研制的PT喷油器试验台可完成喷油量和密封性2个项目测试工作,是PT喷油器性能测试和故障检查的理想设备。该试验台主要由油路系统、气路系统、电控系统组成,由外接空气压缩机供气,外接电源供电,由电动机带动燃油泵供油。该试验台采用与发动机相同形状的凸轮,通过电动机、胶带传动装置及机械油压复合夹紧机构,模拟PT喷油器在发动机上的实际工作状态,运用光电燃油计量显示系统进行检测。为保
PT injector test bench developed by our company can test two items of fuel injection quantity and tightness, which is the ideal equipment for PT injector performance test and fault inspection. The test bench is mainly composed of oil system, gas system and electronic control system. The external air compressor supplies gas and external power supply, and the motor drives the fuel pump to supply oil. The test bench uses the same shape of the engine cam, motor, tape drive and mechanical hydraulic compound clamping mechanism to simulate the PT injector on the engine’s actual working state, the use of optical fuel metering display system for testing.
