- Title
Numerical Simulation and Experimental Research of Pump Head of Hydraulic Diaphragm Pump.
- Abstract
The pump head of the hydraulic diaphragm pump is a key component of the metering pump, which has a large impact on the metering accuracy and reliability and affects the normal operation of medium transportation and safe production. Based on CFD method, the dynamic mesh model provided by software FLUENT is applied for dynamic numerical simulation of the three-dimensional flow field of the diaphragm pump and to establish the calculation model for the motion law of the ball valve of the reciprocating pump. Through visual tests and measurements of the ball valve motions, the simulation and measurement results under the same condition are compared, and the two are basically consistent. Combined with the measurement of fluid pressure fluctuation in the pump and valve, the pressure fluctuation caused by the ball valve motions is analyzed, and the influence of speed ratio, stroke and medium viscosity on ball valve lift is deduced, which provides a reference for the design and selection of ball valves for the pump head.
