Title       A design of small hydraulic pump station     

Abstract

This article describes the design of small hydraulic pump station, the first governor of the hydraulic system through the program, the pressure control scheme, the hydraulic circuit and hydraulic power source to work out the analysis and selection of the hydraulic system diagram. By a known pressure and flow hydraulic pump and tank to complete the design and calculation, and then hydraulic components required for selection. The selected hydraulic components connected through a plate mounted on the hydraulic valve block and complete the passage through the design and calculation settings and valve block layout. According to different requirements of different oil Outward flow calculation and selection of fittings and hydraulic accessories. Finally, checking the hydraulic system performance under reasonable circumstances, the use of hydraulic components solidworks software to complete its assembly drawing, and then piping connections together to achieve three-dimensional modeling for hydraulic pump station, complete the design of small hydraulic site .
