Design And Analysis Of Water Hydraulic Pump With Oil Hydraulic Transmission

Modern hydraulic technology is the use of water,sea water to replace the hydraulic oil to form a new drive technology or transmission technology.Modern hydraulic drive technology is different from the ancient hydraulic pressure technology and the modern hydraulic drive technology,the main reason is that there are many aspects of water pressure technology,such as special media,materials and structures,etc.At present,mechanical and hydraulic transmission and other traditional power transmission technology has been developed quite mature.However,most of the traditional power transmission is difficult to avoid environmental pollution and waste of resources,and so on,therefore,under the driving force of technological innovation,hydraulic technology is emerging in people's vision.In order to achieve the purpose of energy saving,environmental protection,the world gradually began in-depth study of the hydraulic technology,and put a lot of manpower and resources,in the domestic water technology started late,but has hydraulic technology as the green engineering project development from.The proportional control hydraulic variable pump of the invention adopts a hydraulic component and a hydraulic element to carry out the mixed design.Hydraulic pump structure suitable for transmission medium.The utility model is also suitable for being used as an energy transmission hydraulic pump structure.The hydraulic cylinder is controlled by the hydraulic element,so that the hydraulic cylinder is moved back and forth to realize water absorption and drainage,and the function of the hydraulic variable pump is realized.The system uses only a small number of simple structure,low technical requirements of the hydraulic components(hydraulic cylinder,one-way valve,or accumulator),the drive and control design using hydraulic components.As the development of the technology of hydraulic components is mature and reliable,the control performance is high,and the development level is high,the drive and control of the hydraulic pump can effectively reduce the volume,improve the reliability and improve the control performance.Firstly,according to the output to meet the requirements,put forward the overall design scheme of the hydraulic pump;in addition,as a kind of pressure,there are high demands on the integration of the integration of hydraulic components,small size,light weight and compact structure is the key to solve the problems of structural design of a.The tank hydraulic system of the hydraulic pump volume impact,therefore,combined with the hydraulic characteristics of variable pump,the water tank,and through the Fluent optimization design,effectively reduce the volume of the tank;and the hydraulic cylinder hydraulic cylinder is an important element in the variable pump,the whole structure of the mass is larger.In order to realize the idea of lightweight structure,the finite element model.of hydraulic cylinder is established by using ANSYS Workbench.In order to ensure the strength and stiffness to meet the design requirements,not only reduce the quality of institutions,but also improve the natural frequency of the hydraulic cylinder,to avoid the resonance,which provides a reference for the optimization of other institutions in the system of hydraulic pump.
