Description
Technical Field
The invention relates to the field of metal pipe inner wall repair, in particular to a multifunctional device suitable for electric cleaning and electroplating repair of a metal pipe inner wall.
Background
Currently, collar methods, local lining methods and the like are the most commonly used methods in pipe fitting repairing technologies, and although the methods are the current mainstream methods, the methods still have some defects in the actual production and use processes. The collar method is to repair by using a method of installing a water-stop collar outside the pipe fitting, and has the defects that the method cannot effectively inhibit or prevent the corrosion of the inner wall of the pipe fitting, and on the other hand, the method needs to add the water-stop collar outside the pipe fitting, so that the method cannot be used in a specific working environment; the local lining method is to fix a glass fiber hose fully soaked by resin on a pipeline repairing device, then move the pipeline repairing device to a position where a pipe fitting is to be repaired, make the glass fiber hose closely attached to the inner wall of the pipe fitting to be repaired by inflating the pipeline repairing device, and repair the pipe fitting after the hose is cured, and has the defect of complex operation steps compared with other local repairing technologies. The metal pipe plays an indispensable role in daily life and industrial production and manufacture of people, but because the inner wall of the metal pipe is easy to wear, corrode, erode and the like, the service life of the metal pipe is reduced, even the metal pipe is directly scrapped, the life and development of people are seriously affected, so that the technology for repairing the inner wall of the metal pipe is already a key technology, and the requirements for the metal pipe are also higher and higher along with the development of society. For example: the pipeline for conveying petroleum has the problems that hard particle impurities are contained in crude oil, so that some local areas of the inner wall of the pipeline are easy to erode, pitting and even coating falling off, but the pipeline is difficult to repair by using a common method due to the limitation of the working environment; the hydraulic cylinder is easy to cause problems in the working process, particularly the inner surface of the cylinder is easy to scratch, if the hydraulic cylinder is not timely processed after being strained, the hydraulic cylinder can be damaged too early, but the common method has poor repairing effect because of the limitation of the working environment; for workpieces with high precision requirements, the common repair method cannot meet the precision requirements. There is thus an urgent need for new repair devices to meet this demand.
The principle of the electrochemical deposition technology is that oxidation-reduction reaction occurs on an electrode under the action of an external electric field through the migration of positive and negative ions in an electrolyte solution, so as to form a plating layer. Because the potential difference of the anode and the cathode becomes large under the action of an externally applied electric field, a large amount of metal ions move towards the cathode in a directional way, and therefore, the electrochemical deposition technology can rapidly form a metal coating on the surface of the substrate. The nano particles have strong chemical property stability, corrosion resistance, antifriction and wear resistance and the like, and the addition of a certain amount of nano particles in the plating solution can obviously improve the performance of the plating layer, so that the service life of the part is greatly prolonged. The nano particles are adsorbed on the surface of the nano particles in the electrochemical deposition process mainly by virtue of ions in the plating solution, so that the nano particles are driven to move in the directional movement process of the ions, and then the nano particles are subjected to oxidation-reduction reaction after moving to the surface of a cathode, and the separated metal plating layer wraps the nano particles into the plating layer, so that the performance of the plating layer is enhanced, and the technology has good development prospect in practical application. The principle of electric cleaning is the same as that of electrochemical deposition technology, except that the cathode and anode are completely opposite in connection mode, under the action of an external electric field, oxidation reaction occurs on the surface of a pipe serving as an anode, a large number of bubbles are generated on the surface of the pipe, the bubbles are separated from the surface of the pipe when the bubbles are gathered to a certain degree, and meanwhile, the bubbles damage oxide films, stains, residual coatings and the like on the surface of the pipe to expose the substrate, so that a foundation is provided for subsequent work. The electrochemical polishing and the electric cleaning have the same working principle, and when the inner wall surface of the metal pipe fitting is provided with microscopic and macroscopic bumps or high points and burrs at rough positions, the area has a certain tip effect, so that under the action of current and electrochemical polishing liquid, the current density of the area is larger, the corresponding dissolution speed is also fast, and the uneven dissolution ensures that the raised part of the surface is dissolved faster, thereby playing the role of flattening and polishing.
The technology for repairing the pipe fitting mainly comprising an alloy coating or a nonmetallic lining is mainly researched at present through searching and referring related documents at home and abroad, but various performances of the nano composite coating are superior to those of the alloy coating through a great deal of related document researches. The nano particles have certain agglomeration, are not easy to be effectively dispersed in the plating solution, and further cause agglomeration and precipitation of a large number of nano particles, so that the nano particles cannot enter the plating layer. In the prior art, the coagulation phenomenon of the nano particles cannot be effectively solved, so that the dispersibility of the nano particles in the plating solution is poor, the repairing effect of the inner wall of the pipe fitting is greatly reduced, the performance of the plating layer in the actual use process is affected, and the expected effect cannot be achieved.
