Remanufacturing method of high pressure oil pipe

Abstract

The invention discloses a high-pressure oil pipe reproducing method and belongs to the technical field of reproduction of a diesel machine. The method comprises the steps of cleaning disassembled high-pressure oil pipes and removing oil dirty on the surfaces of the high-pressure oil pipes; placing the plurality of high-pressure oil pipes in a sand-blasting machine, blasting the surfaces of the high-pressure oil pipes by taking soda ash as grinding particles to remove paint and oil dirty on the surfaces of the high-pressure oil pipes; cleaning the residual soda ash on the surfaces of the high-pressure oil pipes; blowing the residual cleaning fluid on the surfaces of the high-pressure oil pipes; examining the state of the high-pressure oil pipes and sorting out the high-pressure oil pipes in good sueface state; cleaning the inner cavities of the high-pressure oil pipes to achieve the demand of cleanliness, and sorting out the high-pressure oil pipes meeting the reproducing demands; assembling the high-pressure oil pipes into a high-pressure oil pipe assembly part. According to the high-pressure oil pipe reproducing method, the sand-blasting surface cleaning technology is utilized, the surface cleaning speed of the high-pressure oil pipes is accelerated, the cleaning effect is improved; blockage is not generated in the cavities of the high-pressure oil pipes by utilizing the soda ash as the grinding particles and the high-pressure oil pipes are easy to wash, so the reproduction of the high-pressure oil pipes is realized and the utilization rate of old parts is improved.

Description

technical field [0001] The invention belongs to the technical field of diesel engine remanufacturing, in particular to a method for remanufacturing high-pressure oil pipes. Background technique [0002] The high-pressure fuel pipe undertakes the task of transporting high-pressure fuel, and its strength requirements are very high. The high-pressure oil pipe is one of the important parts of the diesel engine, and it is an assembly structure on the diesel engine. In the process of producing and remanufacturing diesel engines in the past, the high-pressure oil pipe assembly that was directly assembled was a new product, and the high-pressure oil pipe assembly that was dismantled from the old engine was directly discarded. However, some of the high-pressure oil pipes in the abandoned high-pressure oil pipe assembly are in good condition. Therefore, the production method of directly discarding the old high-pressure oil pipes will cause a great waste of resources, which is not in ...
