摘要

目的 测试、分析高速螺旋转子泵在不同转速下的性能。方法 对高速螺旋转子泵进行三维建模,并建立其理论流量数学模型,进行样机试制及装配。搭建螺旋转子泵性能测试硬件及软件系统,通过Labview对信号进行控制和采集。结果 螺旋转子泵实际流量与流量波动随着转速的升高呈线性增加,流量波动从转速为2700 r/min时的0.43 L/min增大到转速为8400 r/min时的1.76 L/min。螺旋转子泵转速小于5800 r/min时,转速增加与实际流量增加基本呈线性关系,当转速超过7000 r/min时,实际流量基本不再增加。结论 螺旋转子泵的实际输出流量及流量波动随转速增加而增大,实际输出流量的增大提高了螺旋转子泵的输出压力,而流量波动的增大降低了螺旋转子泵的稳定性。

Abstract

The work aims to test and analyze the performance of helical rotor pump (HRP) operating at different speeds. Three-dimensional model of HRP and mathematical model of theoretical flow rates were built. Prototype of HRP was processed and assembled. Hardware and software system used to test the performance of HRP was established. The signals were controlled and captured by Labview. The actual flow rates and flow rate fluctuation of HRP linearly increased with the increase in the rotational speeds. Flow rate fluctuation was observed and went up to 1.76 L/min from 0.43 L/min when the rotational speed increased to 8400 r/min from 2700 r/min. When the rotational speed was lower than 5800 r/min, the increase of rotational speed was basically linear with the increase of the actual flow rate. However, the actual flow rate basically no longer increased when the rotational speed exceeded 7000 r/min. The actual output flow and flow rate fluctuation of the HRP increase with the increase in the rotational speed. The increase of actual output flow improves the output pressure of the HRP; however, the increase of flow rate fluctuation decreases the stability of the HRP.
