3 forklift in the engine and the application of test First, we will assemble the six injector installed in the HVAC imports TCMFD60Z7 forklift truck, I use October, the performance has been good. Again in the injection pump test stand fuel pump assembly debugging good domestic assembly capacity tests, the use of more than half a year, the good performance indicators. Comply with the recommendations of the Technical Department, in July 1998 and assembled a homemade fuel pump assembly of the people's livelihood Ports Corporation installed in the Shanghai TCM forklift truck imports, the use of a good performance so far. The units that were assembled in domestic fuel pump and injector HVAC can replace imported parts in the original 6 BB1 engine use. 4 Summary of development work 1) evaluation for the assembly of Chinese-made parts will completely replace the fuel pump assembly of imported original pump, and prove the reliability, we have imported from original Chinese-made parts are assembled and the fuel pump assembly and one each in Taiwan, commissioned by the Ministry of Industry Machinery Wuxi Pump Choke Institute to conduct a comprehensive performance comparison tests. The results proved that Chinese-made parts are assembled by the fuel pump assembly, its structure and performance may meet BB1-6 engine maintenance requirements, save foreign exchange and improve the economic efficiency of enterprises. 2) from domestic assembly of the fuel injector and fuel pump assembly in the engine installation and operating methods were similar and imports, into the pipeline, to tubing, high pressure pipeline are no changes can be easily replaced by domestic Injector and fuel pump assembly, the assembly will not only meet the requirements of the exchange will not be affected, and more than 90 percent of Chinese-made parts can be bought with the injector and fuel pump interchangeable parts, repair use is extremely convenient. 3) the domestic assembly of the fuel injector and fuel pump assembly import prices were only original injector fuel pump assembly and the 8% to 1 0%, the need for regular maintenance of the three pairs of precision dual (plunger , the oil valve and nozzle) is only 6.6 per cent of the prices of imports. 6 BB1 entire fuel system - a total of more than 300 parts 160 kinds of parts, which Guochanhualu: has reached more than 90 per cent, and domestic assembly of the fuel injector and fuel pump in all the consumable parts are sufficient supply to users Maintenance is easy to use, and low price.
