Description
Technical field
The utility model relates to a kind of shaft seal, relates in particular to a kind of efficient shaft seal, belongs to stirring reaction device structure component technology field.
Background technique
Shaft seal is a kind of friction sealed or stuffing box, in order to prevent compressor or the leak of liquid between other conveying equipment for fluid substances axle and bearing.Shaft seal is the seal arrangement preventing pump shaft and housing place from leaking and arranging, and conventional type of shaft sealing has packing seal, mechanical seal and power envelope, the shaft seal normally packing seal of reciprocating pump, when conveying does not allow leaking medium, can adopt diaphragm-type reciprocating pump; The shaft seal of rotary pump mainly contains packing seal, mechanical seal and dynamic seal.Shaft seal is in the market a lot, but the following problem of ubiquity: 1) complicated structure, cost is higher, and detachable maintaining comparatively bothers, 2) sealing effect is poor, and the assembly precision of whole equipment is reduced; 3) replacement frequency is fast, and service time is shorter, and therefore, a kind of new technological scheme of exigence solves above-mentioned technical problem.
Model utility content
The utility model is just for the technical problem existed in prior art, and provide a kind of efficient shaft seal, this equipment de-sign is ingenious, compact structure, and cost is lower, and this shaft seal good sealing effect, working life is longer, has saved cost.
To achieve these goals, the technical solution of the utility model is as follows, efficient shaft seal, described shaft seal comprises shaft seal body, lubricating cup, gland and filler, described shaft seal body is arranged between stirring shaft and Stuffing box, described gland is arranged on the top of filler, by bolt, nut, gland is fixed on Stuffing box, described lubricating cup is arranged in the middle of filler, the side of described shaft seal is provided with water jacket and coolant outlet, described efficient shaft seal also comprises stationary seal ring, and described stationary seal ring is arranged in shaft seal body.Whole Technical Design is ingenious, compact structure, good sealing effect, substantially increases the assembly precision of product.
Improve as one of the present utility model, described shaft seal also comprises seal ring, and described seal ring is arranged on the outside of filler, strengthens its sealing effect further.
Improve as one of the present utility model, described shaft seal also comprises lining, and described lining is arranged on gland.Stuffing box gland on lining is set, greatly can improve assembly precision, make axle have good centering, when filler compresses, stressed more even, ensure that packing seal carries out work in a good condition.
Improve as one of the present utility model, described filler is set to annular packing.Because the filler of other shapes is turning the very difficult guarantee of timing size, filler can not ensure often to enclose all even good contacts with axle after compressing completely, and stress is bad, causes charging seal failure and leaks, and adopt annular packing, sealing effect improves greatly.
Relative to prior art, the advantage of this technology is as follows: 1) the utility model overall construction design is ingenious, and compact structure is practical; 2) this technological scheme good sealing effect, substantially increases the assembly precision of product; 3) Stuffing box gland on lining is set, greatly can improve assembly precision, make axle have good centering, when filler compresses, stressed more even, ensure that packing seal carries out work in a good condition; 4) being provided with stationary seal ring in this technological scheme, further enhancing its sealing effect, 5) this technological scheme cost is lower, is convenient to apply on a large scale.
Accompanying drawing explanation
Fig. 1 is the utility model perspective view;
In figure: 1, Stuffing box, 2, coolant outlet, 3, water jacket, 4, lubricating cup, 5, Gland, 6, nut, 7, bolt, 8, seal ring, 9, cooling water intake, 10, filler, 11, lining, 12, stirring shaft, 13, stationary seal ring.
Embodiment
In order to deepen understanding and cognition of the present utility model, below in conjunction with the drawings and specific embodiments the utility model be further described and introduce.
embodiment 1: see Fig. 1, a kind of efficient shaft seal, described shaft seal comprises shaft seal body, lubricating cup 4, gland 5 and filler 10, described shaft seal body is arranged between stirring shaft 12 and Stuffing box 1, described gland 5 is arranged on the top of filler 10, by bolt 7, nut 6, gland 5 is fixed on Stuffing box 1, described lubricating cup 4 is arranged in the middle of filler, the side of described shaft seal is provided with water jacket 3 and coolant outlet 2, described efficient shaft seal also comprises stationary seal ring 13, and described stationary seal ring is arranged in shaft seal body.Whole Technical Design is ingenious, compact structure, good sealing effect, substantially increases the assembly precision of product,
embodiment 2: see Fig. 1, improve as one of the present utility model, described shaft seal also comprises seal ring 8, and described seal ring 8 is arranged on the outside of filler, strengthens its sealing effect further.All the other structures are identical with embodiment 1 with advantage.
embodiment 3: see Fig. 1, improve as one of the present utility model, described shaft seal also comprises lining 11, and described lining 11 is arranged on gland 5.Stuffing box gland on lining 11 is set, greatly can improve assembly precision, make axle have good centering, when filler compresses, stressed more even, ensure that packing seal carries out work in a good condition.All the other structures are identical with embodiment 1 with advantage.
embodiment 4: see Fig. 1, improve as one of the present utility model, described filler is set to annular packing.Because the filler of other shapes is turning the very difficult guarantee of timing size, filler can not ensure often to enclose all even good contacts with axle after compressing completely, and stress is bad, causes charging seal failure and leaks, and adopt annular packing, sealing effect improves greatly.All the other structures are identical with embodiment 1 with advantage.
