Vacuum pump drive parts wear is a common problem, including the bearing bit, bearing seat, bearing room, keyway and thread and other parts of the traditional methods to repair welding and brush plating spraying, but both have certain drawbacks: welding high temperature Resulting in thermal stress can not be completely eliminated, easy to cause material damage, resulting in parts bent or broken; and brush plating coating thickness limit, easy to peel off, and the above two methods are used metal repair metal, can not change the "hard Hard "with the relationship between the combined effect of various forces will still cause wear and tear again. Contemporary Western countries to address the above problems and more use of polymer composites repair methods, and more applications have its superior adhesion, excellent compressive strength and other comprehensive performance. Application of polymer materials repair, free demolition, free machining. Neither the impact of welding thermal stress, repair thickness is not limited, while the product has the metal material does not have the concession, shock absorption equipment can be shocked to avoid the possibility of wear and tear, and greatly extend the life of equipment components for the Enterprises save a lot of downtime, creating enormous economic value.
