Abstract:In order to change the status quo of the traditional manual push and pull cleaning method,based on the use characteristics and technical requirements of gun cleaning machine,through the analysis of the basic structure and related parameters of high-pressure water jet,the solid finite volume method was used to simulate the cleaning process,and the cleaning mechanism of water jet was studied.A gun cleaning machine based on high pressure water jet was designed to clean carbon,copper and nylon in the gun bore in all directions,and it could achieve the reciprocating movement of telescopic rotation in the gun bore.In view of the domestic demand and problems existing in the maintenance process of the gun bore,combined with the actual situation of field operation,the design scheme,device composition and working principle of the gun bore cleaning device were put forward.The device was adopted overall layout.On the premise of ensure the use function,the equipment operation is simple,practical,and can do further structure optimization.To a certain extent,the transmission chain is shortened,to ensure equipment normal operation,reduce the occurrence of fault,make late maintenance more convenient,so its service life is prolonged to the maximum extent.
