【摘要】：螺桿泵采油技術(shù)現(xiàn)如今已經(jīng)得到廣泛應(yīng)用。螺桿泵主要是由金屬轉(zhuǎn)子和橡膠定子組成，，其中橡膠定子襯套是螺桿泵系統(tǒng)的關(guān)鍵部件之一，其使用壽命直接影響到螺桿泵整體的使用壽命及開采效率，因此研究橡膠定子的制造過程及工藝十分重要。螺桿泵橡膠定子的制造方法一般分為壓注法和注射法，但目前鮮有人從理論上定量分析生產(chǎn)過程中各物理參數(shù)、橡膠流動過程中各種內(nèi)部參數(shù)的變化及相互聯(lián)系。對此，論文開展了螺桿泵橡膠定子注模過程的仿真研究。 首先構(gòu)建螺桿泵橡膠定子的有限元模型，通過模流分析軟件對橡膠定子注模過程進行仿真。分析澆口位置對注模過程的影響；著重研究注模過程中不同流速與填充時間、注射壓力、鎖模力、最大剪切速率之間的關(guān)系并確定最佳工藝參數(shù)范圍；研究了等壁厚螺桿泵橡膠定子注模過程的流態(tài)，并與常規(guī)螺桿泵橡膠定子的注模流態(tài)進行對比分析，從注模角度確定了等壁厚螺桿泵的優(yōu)勢；通過正交試驗法中極差分析，研究了對于不同目標影響因子的顯著性，并確定最佳注模參數(shù)組合。 通過以上分析，得出對于論文中所采用定子模型的最佳注模參數(shù)范圍，形成了一般螺桿泵橡膠定子模型的注模過程分析方法，并可以確定注模過程中最佳模具溫度、熔體溫度、填充速率等注模參數(shù)，最后通過正交試驗法可以得出最優(yōu)注模參數(shù)組合。
[Abstract]:Screw pump oil recovery technology has been widely used today. The screw pump is mainly composed of metal rotor and rubber stator, in which the rubber stator bushing is one of the key components of the screw pump system. Its service life directly affects the whole service life and mining efficiency of the screw pump. Therefore, it is very important to study the manufacturing process and process of rubber stator. The manufacturing methods of screw pump rubber stator are generally divided into pressure-injection method and injection method. But at present few people quantitatively analyze the physical parameters in the production process and the change and interrelation of various internal parameters in the rubber flow process. In this paper, the simulation of injection process of screw pump rubber stator is carried out. Firstly, the finite element model of rubber stator of screw pump is constructed, and the injection process of rubber stator is simulated by the software of mold flow analysis. The influence of gate position on the injection process is analyzed, and the relationship between different flow rate and filling time, injection pressure, mould locking force, maximum shear rate and the optimal range of process parameters are studied. The flow state of the rubber stator of the constant wall thickness screw pump is studied, and the flow state of the rubber stator of the conventional screw pump is compared with that of the conventional screw pump. The advantages of the equal wall thickness screw pump are determined from the angle of injection mold, and the range difference analysis of the orthogonal test method is used to determine the advantages of the equal wall thickness screw pump. The significance of influencing factors for different targets was studied and the optimal injection parameters were determined. Through the above analysis, the optimum parameters range of the stator model used in the paper is obtained, and the injection process analysis method of the general screw pump rubber stator model is formed, and the optimum mold temperature and melt temperature can be determined during the injection process. The filling rate is equal to the injection parameters, and the optimal injection parameters can be obtained by orthogonal test.
