Experimental Study on Pressure Characteristic of Pulsed Liquid Jet Pump

The pulsed jet and the steady jet were applied to carry on experimental study on the pressure characteristic of the liquid jet pump.It is analyzed that the pressure variation characteristic of the liquid jet pump and the influence on the performance of jet pump.The results show that the pressure characteristic and performance of the pulsed liquid jet pump is better than the steady liquid jet pump.The results prove that pulsed jet is an effective way to enhance the jet pump's efficiency.The research results provide reliable basis for deeply studying pulsed liquid jet pump's fundamental performance.
