The membrane isolation pumps is one kind of hydromass transportation hydraulic system,can reduce the cartage expense greatly,but indirectly brings the huge social efficiency,safe reliable,the work rate is high,may not stop nearly carries on the whole year to transport,does not have the material to lose nearly,the easy automatic control,to be advantageous for the maintenance management The hydraulic pressure diaphragm pump is one kind of fill domestic diaphragm pump which we develops in high-pressured,the small curr ent capacity pulp transportation aspect blank pumps plants,it and the common diaphragm pump main difference is:Has substituted for the crank connecting rod,the reduction gear using the hydraulic pump and so on aseries of equipments direct drive piston motion,this causes its structure is greatly the simplification,the cost drops greatly;When at the same time also requests the piston the commutation confidential assurance extremely accurately,but must realize this point theoretically and all has the very great difficulty in fact.

膜隔离泵就是一种浆体输送的液压系统，能大大降低运输费用，可间接带来巨大的社会效益，安全可靠，作业率高，几乎可不停地进行全年输送，几乎没有物料损耗，易于自动控制，便于维护管理。液压隔膜泵是我们开发的一种填补国内隔膜泵在高压、小流量矿浆输送方面空白的泵种，它与一般的主要区别是：利用液压泵取代了曲柄连杆、减速器等一系列装置直接驱动活塞运动，这使其结构大为简化，成本大大下降；但同时也要求活塞的换向时机要把握得非常准确，而要实现这一点理论上和实际上都存在很大难度。

The design mainly works on many factors which effecting the volume efficiency of fracturing pump. These factors are working conditions of the pump,imbibitional valve,expulsive valve,clearance volume,sealing property, condensability of influent, liquid leakage and elastic defletion of pump cylinder. Based on these facors, we should induce the efficiency expression, famulate differential eguation and emulational mathematical model of fracturing pump.

本设计主要针对影响压裂泵容积效率的因素如：泵的工作情况、吸液阀结构参数、余隙容积、密封性能、液体的可压缩性、液体泄漏、泵缸的弹性形变等方面进行分析，在此基础上导出效率的表达式，建立微分方程，并建立压裂泵效率仿真的数学模型。

In static analysis, small deflection theory of circular plate and electrostatic actuating theory are adopted to simulate electrostatic-structural coupled process. In modal analysis, harmonic response analysis and nonlinear transient dynamic analysis of pump membrane, the fluid in the pump is regarded as an additional mass acting on the pump membrane to approximately substitute the effect of fluid field on pump membrane, which reduces the amount of calculation and improves simulation efficiency.

其中在静态分析中，利用圆型薄板的小挠度变形理论和微机电系统中的静电力驱动理论来模拟静电－结构耦合过程；在泵膜的模态分析、谐响应分析以及非线性瞬态分析中，把腔内的流体当作附加质量作用在泵膜上，近似代替流场对泵膜的影响，从而减小计算量，提高了仿真效率。

paramedic should be strengthened ceaselessly about the retraining that accuses demulcent pump knowledge oneself, undertake to the patient before accusing demulcent pump to apply oneself; of true propaganda and education is in the life style that the rigor in accusing demulcent pump to use a process oneself observes a patient is asked for, enhance the security that accuses demulcent pump cure oneself and effectiveness, rise nurse quality.

结论护理人员应不断加强有关自控镇痛泵知识的再培训，在自控镇痛泵应用前对患者进行正确宣教；在自控镇痛泵应用过程中严密观察患者的生命体征，加强自控镇痛泵治疗的平安性和有效性，提高护理质量。
