Abstract

For a long time, in China's auto parts industry, the fuel pump valves open and close feature detection, has been using the sixties and seventies the traditional method - manual or semi-automatic mode, this traditional inspection methods and complex system structure and the test accuracy is not high, heavy workload, long cycle detection inefficiency, the valve can not be efficiently and accurately test the features, it is difficult to meet the requirements of modern industrial production. Shortcomings of traditional detection methods, the paper of the fuel pump valve testing technology are discussed, both from the theoretical and experimental work on the fuel pump valve characteristics were analyzed, and combined with a fuel pump auto parts plant assembly line project development and design characteristics of the fuel pump valve opening and closing line detection system, using gas instead of oil detection test method has been applied for a Chinese invention patent, patent application No. 200510018668.X. The new fuel pump valve operating characteristics of intelligent testing device, high detection efficiency, small error can not only detect the static properties of the fuel pump valves, but also for its dynamic performance test, suitable for fuel pump assembly production line online testing, which can overcome the fundamental shortcomings of traditional detection methods, in order to correctly grasp the performance and status of the valve. In this paper, some research work carried out as follows: (1) study the development of automotive fuel system; analyzes the necessity of intelligent detection system development and market prospects. (2) depth of the fuel pump system, including EFI system's main component structure and working principle, the fuel pump electronic injection system in the role of the oil seat assembly structure and operating characteristics analysis. (3) presents the fuel pump valve operating characteristics of intelligent testing device design program, in accordance with the one-way valve, relief valve performance requirements and test methods, the design of the system means the overall program. (4) In the analysis of the traditional defect detection method is proposed based on the detection of the gas passage path instead of a new detection method. (5) were carried out for the bench mechanical part of the design, pneumatic part of the design, the circuit part of the design, and software part of the design and research. With the rapid development of computer technology, computer technology used in hydraulic testing techniques have shown high precision, test speed, greatly reducing the workload of superiority. Fuel pump valve operating characteristics of intelligent on-line detection technology for valve testing technology has opened a new approach to development. According to the literature search and apply for patent novelty search results, carried out at present there are no studies of this new detection device. Therefore, with regard to the fuel pump valve operating characteristics of intelligent testing device research and development, has a certain theoretical significance, and has broad application prospects and economic value.
