In the operation of the equipment in the production, because the installation does not reach the designated position, maintenance is not timely, lubrication and other factors, lead to shaft head are often damaged, bearing chamber wear phenomenon also frequently occurred.
Bearing chamber wear problems once appear, parts replacement is costly, manufacturing cycle is longer than the other.
Traditional methods generally use machining after welding to repair, and surfacing can make parts surface at high temperature, causing parts deformation or cracks, obtained by machining size cause downtime greatly extended.
Once appear in the process of running fit clearance will have severe damage to the drive shaft and gear, a significant outage production accident, the enterprise will be huge economic losses.
Than traditional in bearing chamber wear online repair solutions such as machining, Mosaic collar after repair welding, brush plating, spraying, pitting, scrap, etc. , these methods are to some extent cope with the demands of the production, but can't fundamentally solve the problem, and continuous production also planted hidden danger to safety, such as high temperature deformation, crack, coating fall off;
At the same time, the continuation of the traditional methods of equipment management work also won't bring substantial improvement.
Compared with the traditional technology, sauvy carbon nanometer polymer repair technology is relatively mature and high cost performance of a kind of maintenance plan.
Short time, low cost and good effect is several main characteristics of the technology.
The material as a function of high-tech materials, the future can not only change the way the user maintenance, and make the maintenance more simple, faster and more efficient, more economical, more environmental protection, equipment, long cycle life.
Caused by wear and tear down, for example, in view of the driving part, basic realization of the 3 ~ 6 hours rapid repair and restore production.
Run, run, drip, leak, which can realize the majority of cases of non-stop governance.
Sauvy SD7101H carbon nano polymer material has excellent adhesion, resistance to pressure and the comprehensive performance, through on-site rapid construction can bearing a on-line repair of wear, as long as the show wear surface, repair quickly and can effectively avoid the secondary equipment wear increase the service life of the equipment.
Sauvy materials and application technology can make the enterprise field repair quickly and efficiently in the first place, effectively avoid the equipment downtime for a long time, production and the benefits of losses;
Effectively avoid shipping costs, hoisting construction costs and security aspects of the comprehensive factors, to ensure the personal safety and enterprise loss, saves valuable production time for the enterprise.
