Embodiment
Fig. 1,2,3 shows a kind of structural drawing of acid-alkali-corrosive-resisting spring mechanism.In figure, this acid-alkali-corrosive-resisting spring mechanism comprises a spring body 1, spring body 1 adopts the spring steel of rectangular cross-section to roll into sped structure, the two ends of spring body 1 are plane, on the upper-end surface of spring body 1 and lower end surface, set gradually a corrosion-resistant rubber cushion 3 and a spring seat board 2.Spring seat board 2 is provided with an endoporus 2c and an otch 2e, at the annular end of otch 2e mono-side, is made into kinking structure 2d under arc, and described corrosion-resistant rubber cushion 3 adopts the structure (being provided with identical endoporus and otch) matching with spring seat board 2.Spring seat board 2 outer peripherys are provided with 6 evagination bending plate 2a that match with spring body 1 end external cylindrical surface, and the inner periphery of endoporus 2c is provided with and 6 convex bending plate 2b that match at the inner cylindrical surface of spring body 1 end.Corrosion-resistant rubber cushion 3 is placed in to the bottom of spring seat board 2, both otch alignment, allow kinking structure 2d under the arc of spring seat board 2 be positioned at the lower position of the spring terminal afterbody 1a of spring body 1.The surface of spring body 1 is provided with the glue-line of anti-acid and alkali corrosion.
Fig. 4,5 shows the semi-finished product structure figure of spring seat board.In figure, spring seat board 2 outer peripherys are provided with 6 not yet evagination bending plate 2a of bending, and the inner periphery of endoporus 2c is provided with 6 not yet convex bending plate 2b of bending.For ease of the bending of evagination bending plate 2a, the both sides of evagination bending plate 2a are respectively provided with a technology groove 2f.
Adopt above-mentioned technological scheme, the features such as that the having of this spring mechanism installed is simple, high pressure, high compression amount, acid-proof alkaline are good, long service life.
High elasticity high compression amount: for the demand of pressure filter equipment, adopt < < spring design software > > design to meet spring hyperpressure and that guarantee high compression amount, this spring can guarantee long service life according to analog data and actual fatigue test checking.
High acid resistant alkali, highly corrosion resistant: by special surface processing, can reach and exceed the acid resistant alkali of 50 times of general springs, corrosion-resistant cycle.
Overlength life cycle: changed Traditional Thinking in the design concept of conventional springs.Point both ends of the spring and tight is carried out to opening processing, guarantee that spring itself all covers corrosion resistant coating.Because in the delivery process of spring, did the also tight point of opening processing in earlier stage and wanted also tightly, and will produce counterclockwise movement, the corrosion resistant coating on as easy as rolling off a log like this destruction spring surface with spring volume below.Adopted a kind of spring seat board and corrosion-resistant rubber cushion for this reason, can guarantee that spring fabulous assurance cover coat in delivery process is not damaged.By checking, in not abnormal appearance of 50,000 (being equivalent to 6 years spreadable lifes) spring surfaces of delivery.In marginal test process, can accomplish to deliver 100,000 also not abnormal appearance of (being equivalent to 11 years spreadable lifes) spring surface.According to the working life estimation that guarantees 5 years, if pressure filter adopts this spring mechanism, than the pressure filter that uses original spring because of safeguard and slow down and cause expensive and inefficient, approximately can reduce millions of economic losses.
