How about the development trend of fuel pump test bench? The development trend of the injection pump test bench has the following points: (1) Because the injection pump test bench is mainly used in the oil pump nozzle manufacturers and maintenance debugging, and manufacturers because of the production is batch, therefore, it requires fuel injection test bed Of the high degree of automation, such as rapid installation of fuel injection pump and rapid digital measurement of fuel injection; and maintenance requirements of the fuel injection pump test bench should be able to adapt to a variety of fuel injection pump debugging, with a full range of accessories. (2) In the future, the technical development of fuel injection pump test bench should mainly focus on making full use of computer measurement and control technology so that the measurement of various conditions and technical parameters in fuel injection pump commissioning can be automatically measured digitally to adapt to the technology and quality of fuel injection pump products Constantly improve the fuel pump test bed production speed control technology, the motor direct output, the transmission principle is to input three-phase AC to the inverter, the inverter will be three-phase AC into a variable frequency and voltage of the three-phase AC, so that the three-phase asynchronous motor stepless speed regulation.The advantage is speed stability (error I rpm), speed range (0 a 4000rpm), the output torque, over voltage, under voltage automatic protection, overload Automatic protection, energy saving, easy operation, the host of ultra-low noise, reducing the load speed, etc. BD850 fuel injection pump test bed and the first use of speed preset, improve labor productivity; speed, counting, temperature control, positive and negative pressure, spray Advance all the oil pump advance digital display, to achieve the so-called full-function. With the continuous development of frequency control technology, frequency control fuel injection pump test bench in the domestic manufacturers have produced. Different manufacturers choose the inverter control methods are different, fuel pump test bench configuration of different functions, the price will be very different. So the user can not be compared in the choice of price alone, but from all aspects to be considered, such as: Frequency The model, function configuration, production process, pre-sale service, etc., select the best satisfied with the equipment. At present, the domestic fuel pump test bench manufacturers are developing and producing screen display fuel pump test bench, the so-called screen test bench is The test bed speed, counting, temperature control, positive and negative pressure, pump rack travel table and other functions through the computer screen display, and the test bed fuel pressure, flywheel scale, especially the amount of oil has not yet achieved screen display. Oil screen has appeared in foreign countries, is still a high-tech projects in China, is tackling the problem, has been gratifying results. Currently on the market screen injection pump test bench in its configuration vary widely, and the control method is not The same, thus resulting in a great disparity between the price of the manufacturer, the user should pay attention to compare the configuration is complete, the function is perfect. With the pump hair Exhibition, injection pump test bed is also growing.Nowadays there has been electronic fuel injection pump, common rail system, led to the measurement of electronic governor special equipment-EDC (or ECD) and common rail test system Therefore, this requires that we fuel pump test bed manufacturers should work harder in this regard to meet the continuous development of fuel injection pump.
