Description

Technical Field

[0001] The invention relates to the field of common rail pipe processing, in particular to a port grinding device used for processing a common rail pipe of an engine. Background Art

[0002] The common rail pipe is the main component of the engine. The common rail pipe is in a "T" shape. The left and right ends of the oil pipe (for sensor and circuit installation ends) and one or more connecting ends (for oil inlet ends) are arranged at intervals in the axial distribution in the high-pressure chamber of the oil pipe.

[0003] When the two ports of the common rail pipe are polished, more powder will be generated when the inner wall of the port is polished, and the powder will remain inside the common rail pipe. The traditional method of cleaning the powder inside the common rail pipe is to align the pump mouth of the air pump with the port of the common rail pipe, and then the air pump works to remove the dust and impurities in the common rail pipe through the outlet.
