ABSTRACT:
This invention relates to a wear lining containing rubber e.g. for pumps intended for handling wearing material such as dredger and mud pumps of the centrifugal type, which wear lining comprises a layer of wear rubber rigidly combined with a support plate. One of the problems with wear linings of such pumps is that already in manufacture they must be given a shape corresponding to the shape of the shell of the pump housing in which they are to be mounted, and must be manufactured in sections to permit mounting in their pump housing. For this a great number of moulds is required, which involves great costs of manufacture, and as the known wear linings for pumps are manufactured in sections, mounting thereof will be difficult and time-consuming, at the same time as there will be a joint between two sections, which has turned out to be a part of the wear lining that is exposed to wear. To avoid these problems a wear lining of rubber containing means included in the layer of wear rubber of the lining and increasing the resistance of the wear lining to wear is suggested according to the invention, in which these means consist of pins of metal arranged within the layer of wear rubber in one or more reciprocally separated layers and spaced from each other, which pins are oriented in radial planes extending from the center of curvature and at least across the wear surface of the lining, and of compression in the layer of wear rubber increasing from the support plate towards the wear surface, and produced by bending of the wear lining from a substantially plain state to the intended curved shape.
