Abstract

The invention discloses a rubber material of a bearing used in water. The rubber material comprises the following raw materials: chloroprene rubber, natural rubber, magnesium oxide, zinc oxide, high-abrasion furnace black, a vulcanizing agent, softening heavy oil, stearic acid, Vaseline, an anti-aging agent D, light calcium carbonate, an accelerant CBS and microcrystalline wax. The rubber material for a rubber bearing is obtained by respectively plastifying the chloroprene rubber and the natural rubber by using an internal mixer, then, mixing the plastified product with the residual raw materials, removing rubber in the mixed material, then, carrying out batching-off, cooling and standing, cutting a rubber sheet, then, placing the rubber sheet into a rubber bearing die, vulcanizing the rubber sheet together with a steel jacket of the rubber bearing in a vulcanizing machine, and deburring the vulcanized rubber bearing. The rubber material has the advantages that the rubber material for the rubber bearing has the characteristics of excellent corrosion resistance such as temperature resistance, heat resistance, sunlight resistance, oxygen resistance, acid and alkali resistance and chemical resistance, the service life of the rubber bearing is prolonged, and a water pump is enabled to be suitable for different liquid media.

Description

technical field [0001] The invention relates to a rubber material for bearings in water. Background technique [0002] With the popularization and development of industrialization, water pumps are more and more used in all aspects of industrial production and people's life, especially the submerged long shaft pump is widely used in various industries such as steel mills and water conservancy facilities due to its instant start performance. The impeller of the submerged long shaft pump works under the liquid, the structure is long, the transported liquid is in contact with the transmission shaft, and the transmission shaft of the submerged long shaft is composed of multiple shafts connected, in order to ensure the smooth transmission of the shaft, every All shafts should be equipped with bearings. Since this part of the shaft works in water, ordinary bearings cannot be used. This requires a bearing that can work normally in water. This kind of bearing is a water bearing. The...
