The Research On The CAD System For Dual Horsehead Pump Unit

It is a practical engineering project to research on the CAD system for the Dual Horsehead Pump Unit, of which the purpose is to produce highly efficient pump units, and to resolve the dynamic simulation problem of the flexible rod of the Dual Horsehead Pump Unit.This paper, first of all, demonstrates the development upon the graph supporting library of the CAD system, including integrated output of the three dynamic linked libraries, which are the library of the geometric tools, the library of the graphic tools and the library of the geometric kernel, thus realizing the support and operation to the three-dimensional model in the CAD system for the Dual Horsehead Pump Unit.Secondly, according to the special structure features of the Dual Horsehead Pump Unit, the mathematical model of the motion analysis and dynamics analysis are established, which finally helps to accomplish the design of the analytical modules of the Dual Horsehead Pump Unit, mainly involving the development on the motion analyzing module, dynamics analyzing module and the components designing module as a whole. The CAD system for the Dual Horsehead Pump Unit is a computer auxiliary design system which combines the pump parameter optimization design, the components strength calculation (including finite element analysis) and the pump dynamic emulation all together.In the end, based on the development of the CAD system for the Dual Horsehead Pump Unit, we finished the design of the Dual Horsehead Pump, type CYJ145, and the test to its CAD system. It is based on this kind of CAD system that we can better design the CAD/CAE development platform for the Dual Horsehead Pump Unit, and so, as a result, the study on this subject will definitely have a far-reaching influence on much more advanced oil withdrawal equipments for the oil-field industry.
