| 目的 针对传统柱塞泵结构复杂、灌装稳定性较差，已经无法满足高温、耐腐蚀的高端无菌精密灌装需求，提出利用氧化锆陶瓷的高强度、高硬度、抗刮耐磨性、耐腐蚀性等特性，研究出高精密、高洁净度的陶瓷无阀泵。方法 通过改变传统的柱塞模式，全新设计一种无阀结构，使陶瓷柱塞能在陶瓷缸筒内同时实现周向旋转和轴向运动，获得液体压力差。建立压力和流量的关系模型，提出无阀旋转泵流量控制和精度微调等的实现方法。分析研磨杆制造缸筒的加工工艺，保障高装配精度的工艺方法。结果 当灌装范围为6 mL/r时，最高达灌装精度达0.42%，获得了高性能的氧化锆陶瓷无阀泵。结论 研制的无阀泵灌装具有范围大、灌装精度高等特点，适用于耐高温、耐腐蚀的高端无菌精密灌装行业。 |
| 英文摘要: |
| The work aims to develop valve-less ceramic pump with high precision and cleanliness by utilizing characteristics of zirconia ceramics such as high strength, high hardness, scratch and abrasion resistance and corrosion resistance, because the traditional plunger pump has complex structure and poor filling stability, what can no longer meet the high-end aseptic precision filling requirements of high temperature and corrosion resistance. By changing the traditional plunger mode, a new valve-less structure was designed to make the ceramic plunger rotate circumferentially and move axially in the ceramic cylinder at the same time, and the liquid pressure difference was obtained. The relationship model between pressure and flow was established. The realization methods of flow control and precision fine-tuning were put forward for the valve-less rotary pump. The processing technology of cylinder barrel manufactured by grinding rod and the processing method of ensuring high assembly accuracy were analyzed. When the filling range was 6 mL/r, the highest filling accuracy could reach 0.42%. Valve-less zirconia ceramic pump of high performance was obtained. The developed valve-less zirconia ceramic pump has a large filling range and high filling accuracy. It is suitable for the high-end aseptic precision filling industry with high temperature and corrosion resistance. |
