Polishing and cleaning system and method for inner wall of copper tube

Abstract

The invention relates to the technical field of pipeline inner wall processing, in particular to a polishing and cleaning system for an inner wall of a copper tube. The polishing and cleaning system comprises a coiled tube platform and a polishing circulating device, wherein the polishing circulating device comprises a polishing solution tank, a high-pressure pump, a reversing valve and a pressureregulating valve; an inlet of the high-pressure pump communicates with the polishing solution tank, and an outlet of the high-pressure pump is connected with the reversing valve; an inlet of the pressure regulating valve is connected with the reversing valve, and an outlet of the pressure regulating valve communicates with the polishing solution tank; a working end of the reversing valve is separately connected with a first quick joint and a second quick joint; and the coiled tube platform is used for placing a to-be-polished coiled tube; the two ends of the coiled tube are separately connected with the first quick joint and the second quick joint. The invention further discloses a polishing and cleaning method for the inner wall of the copper tube, and the polishing and cleaning method comprises the following steps of: starting the high-pressure pump, operating the reversing valve at interval to reverse, and enabling the polishing solution to circulate back and forth in a coiled tube; and cleaning the inner wall of the copper tube in a circulating mode. The polishing and cleaning system has the beneficial effects that the inner wall of the coiled tube can be polished, processed and cleaned with high efficiency and high quality.

Description

technical field [0001] The invention relates to the technical field of pipe inner wall processing, in particular to a copper pipe inner wall polishing and cleaning system and method thereof. Background technique [0002] With the continuous growth of social demand, the application fields of copper tubes are becoming wider and wider. For example, medical stainless steel or plastic tubes are being replaced by copper tubes. There are also higher and higher requirements for the quality of copper pipes. Copper tubes are generally produced through a drawing process, and the smoothness of the inner wall cannot meet the requirements of some high-demand occasions. Due to the use of drawing fluid during the drawing process, the cleaning problem of the inner wall is more prominent. There are also many existing technologies for the polishing treatment of the inner wall of the copper tube, but generally the polishing brush head is penetrated into the tube and rotated at high speed for p...

AI Technical Summary

Problems solved by technology

This kind of polishing efficiency is low. The main reason is that it is impossible to polish the inner wall of the entire copper tube produced by continuous drawing on the production line, especially when the tube diameter is relatively small.
