Abstract

The invention discloses an elastic buffer pad special for a pump coupling and relates to the technical field of rubber materials.The elastic buffer pad is prepared from, by weight, 70-80 parts of nitrile butadiene rubber, 20-22 parts of acrylic resin, 10-15 parts of polyvinyl chloride, 8-12 parts of mountain flour, 6-10 parts of hydrogenated castor oil, 6-10 parts of carrageenan, 5-9 parts of diatom ooze, 4-7 parts of fatty acid glyceride, 3-5 parts of bamboo powder, 3-5 parts of tributyl citrate, 2-3 parts of sodium polyacrylate, 2-3 parts of nanometer alumina, 1-2 parts of N,N'-m-phenylenedimaleimide and 30-40 parts of n-butyl alcohol.The elastic buffer pad has excellent resilience, a buffer effect and a long service life, can effectively protect the coupling and accordingly ensures the normal operation of a pump.

Description

Technical field: [0001] The invention relates to the technical field of rubber materials, in particular to a special elastic buffer pad for a pump coupling. Background technique: [0002] The coupling is a part connecting the pump and the motor. The two ends are respectively installed on the motor and the pump shaft and connected by special bolts. The motor drives the pump shaft to rotate through the coupling to transmit torque. The coupling includes an elastic cushion, and the life of the elastic cushion is the life of the coupling, so a good elastic cushion is very important for the coupling. However, the service life of the elastic buffer pads currently on the market is not ideal, and the rebound and buffer effects are not significant, and they need to be lubricated frequently, and the maintenance is cumbersome. Invention content: [0003] The technical problem to be solved by the present invention is to provide a special elastic buffer pad for the pump coupling with ...
