【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]:Objective to test and analyze the performance of high speed spiral rotor pump at different speeds. Methods the 3D model of high speed screw rotor pump was established and its theoretical flow mathematical model was established. The prototype was trial-produced and assembled, and the hardware and software system for testing the performance of the screw rotor pump was built. The signal was controlled and collected by Labview. Results the actual flow rate and flow fluctuation of the screw rotor pump increased linearly with the increase of rotational speed. The flow fluctuation increased from 0.43 L / min at 2700 r / min to 1.76 at 8400 r / min. When the speed of the screw rotor pump is less than 5800 r / min. The increase of rotational speed is linearly related to the increase of actual flow rate, when the rotational speed exceeds 7000 r / min. Conclusion the actual output flow and flow fluctuation of the screw rotor pump increase with the increase of rotational speed, and the actual output flow increases the output pressure of the screw rotor pump. The increase of flow fluctuation reduces the stability of the screw rotor pump.
