【摘要】：为克服单臂螺旋线形阀压电泵单臂阀运行时侧向力造成的阀体在开启与关闭中倾斜而产生的负面影响,有效地发挥螺旋线形阀压电泵阀体"慢开启、快关闭"的优势,首先,构造了悬臂固支旋转对称双臂阀体结构,并针对该阀体设计了对称螺旋线形阀压电泵;然后,进行了悬臂固支旋转对称双臂阀体的力学分析,并据此进行了泵流量关系式的解析;最后,利用实际样机进行了单臂阀与旋转对称双臂阀的阀参数对泵参数影响的试验研究。试验结果表明:在输入电压为220 V、频率为10 Hz时,旋转对称双臂阀的臂宽为0.3 mm时的泵流量最高,达到124.2ml/min;旋转对称双臂阀泵比单臂阀泵流量提高1.25~2.84倍;对称阀的进出口阀臂宽不同时的泵流量大于阀臂宽相同时的泵流量,且进口阀臂宽大出口阀臂宽小时的泵流量大于进口阀臂宽小出口阀臂宽大时的泵流量。
[Abstract]:In order to overcome the negative influence caused by the lateral force of the single-arm spiral valve pressure pump in the course of opening and closing, the advantages of "slow opening and fast closing" of the piezoelectric pump valve body of the spiral valve can be effectively brought into play. The structure of the cantilever clamped rotating symmetrical double arm valve body is constructed, and the symmetrical spiral valve pressure pump is designed for the valve body, and then the mechanical analysis of the cantilever clamped rotating symmetric double arm valve body is carried out. Finally, the effect of valve parameters of single-arm valve and rotating symmetric double-arm valve on pump parameters is studied by using the actual prototype. The experimental results show that when the input voltage is 220V and the frequency is 10Hz, the pump flow rate is the highest when the arm width is 0.3 mm, and the flow rate of the rotary symmetric double-arm valve pump is 1.25U 2.84 times higher than that of the single-arm valve pump. When the inlet and outlet arm width of symmetric valve is different, the pump flow rate is larger than the pump flow rate when the valve arm width is the same, and the pump flow rate of the imported valve arm with wide outlet valve arm width is larger than that of the inlet valve arm with small outlet valve arm width.
