Abstract:In order to obtain the relationship between the plunger displacement of the pressure generator and the output pressure, and to achieve the accurate control of the output pressure, the pressure generation system is first modeled mathematically. Then, based on the effective volumetric elastic modulus model of AMEsim, a new interpolation polynomial function of oil gas content is established to solve the derivative mutation problem in the middle position of saturated vapor pressure and air separation pressure. Then, the influence of air content and temperature on the system pressure transfer process is simulated and analyzed. The results show that the system is greatly affected by air content, but less affected by temperature. For every 0.5% increase in air content, the response time and stabilization time of the system will lag about 0.7seconds, and the displacement of the plunger used to compress the oil bubble will increase about 20mm. Finally, by comparing the simulation and measurement results, it is known that the pressure generation system is affected by the air content, the time consumption and response error of the booster section are generally greater than that of the buck section, and the pressure fluctuation of each measuring point is within the range of ±0.03MPa when the pressure is maintained for 5s.
