Parker hydraulic lifting mechanism is set to introduce the technology in the United States Pike domestic manufacturing,gas transfer pump assembling small hydraulic power systems. The heart of the system and the power source is the micro external gear pumps, its speed up to 3700 Rpm, instantaneous working pressure up to 35 MPa, which addendum circle diameter gear of only 14 mm, but it is also affected by the passing rate system One of the important parts.
Currently, this system is the company's qualified domestic Parker was about 75%.
Through experimental study found that the pump performance is not the main reason for compliance With the Traffic Load When Lifting Mechanism for this indicator. This article is the impact parameter tolerances of micro external gear pumps for the study of the flow from the external gear pump works, combining theoretical research and experimental verification,fuel card management system the mathematical model of miniature external gear pump flow, integrated use orthogonal experimental design, computer simulation and genetic algorithms, quantitative research to solve real business problems will start to analyze the impact of micro external gear pump gear pump performance tolerance parameters, and gives the optimum parameters of gear machining tolerances.
For enterprises to improve product pass rate laid the theoretical and experimental basis,mechanical fuel level gauge to improve the economic efficiency of enterprises, production and development of large quantities of new products have a certain significance.
