隔膜泵驅(qū)動液壓系統(tǒng)研究
[Abstract]:With the rapid development of pipeline transportation technology, diaphragm pump is widely used in chemical, electric, mining, metallurgical and other industries as the equipment suitable for solid-liquid two-phase slurry pipeline transportation. However, the diaphragm pump used in industry mainly adopts crank and slider structure, the equipment is huge, the manufacturing cost is high, and the flow pulsation is large. Therefore, a reciprocating diaphragm pump driven by hydraulic cylinder is proposed in this paper. Firstly, this paper analyzes the flow characteristics of heterogeneous slurry transported by diaphragm pump in pipeline, and establishes the dynamic model of heterogeneous slurry flowing in pipeline. The method of calculating the flow velocity and resistance loss of heterogeneous slurry in horizontal pipeline is obtained. Secondly, the drive scheme of diaphragm pump is determined and the hydraulic system of diaphragm pump is designed. The mathematical model of hydraulic circuit of diaphragm pump driving hydraulic system is established. Through MATLAB/Simulink simulation, the stability of hydraulic system is analyzed, and the system is corrected by PID control method, and the dynamic of driving hydraulic system is optimized. Static characteristic; The simulation model of diaphragm pump driving hydraulic system is built by using AMESim software. The simulation of the whole hydraulic system is carried out to master the motion law of the driving cylinder, the variation law of the pressure and flow rate in the driving hydraulic cylinder and the law of the discharge flow of the pump. Finally, the test platform of diaphragm pump driving hydraulic system is built, the performance parameters of diaphragm pump driving hydraulic system are tested, and the correctness of the system model is verified. The experimental results show that the hydraulic drive system of the diaphragm pump designed in this paper can meet the requirements of material transportation and the output flow of the pump is stable, which verifies the correctness of the theoretical research.
