Background technique
Existing pump housing mechanical sealing device of silicon carbide peculiar to vessel comprises the stationary seal ring, the stationary ring L pad that are socketed on the axle, rotating seat, moving sealing ring, driving ring, rubber cup, spring seat and spring; Described stationary seal ring and stationary ring L pad are fixed on the pump housing, described moving sealing ring is force-fitted on the stationary seal ring, the inwall of described driving ring and axle close-fitting, described driving ring and rotating seat are circumferentially spacing, on axle, described rubber cup is located between rotating seat and the moving sealing ring and between driving ring and the axle, described spring socket sleeve is on axle by the rotating seat close-fitting for described moving sealing ring, and with the rotating seat close-fitting, described spring housing is on spring seat.
Moving sealing ring assembly in this mechanism rotates along with the rotation of axle, and stationary seal ring and moving sealing ring form the sealing flour milling, forms liquid film in the sealing flour milling and realizes inner with extraneous mechanical seal, avoids extraneous working medium to leak into inside.
The pump housing mechanical sealing device of silicon carbide peculiar to vessel of above prior art has the following disadvantages: because described driving ring and the circumferential spacing employing of rotating seat is that axial bore embedding corresponding on a plurality of axial projection and the rotating seat end face of driving ring cooperates, to realize circumferential interlock, both circumferential driven natures of this Placement are also relatively poor; And in actual moving process, axial projection and axial bore can cause both to come off (separation) when frequently beating because of excesssive gap, thereby whole mechanical seal was lost efficacy.
The model utility content
Technical problem to be solved in the utility model is, provide a kind of driving ring with drive seat circumferentially driven nature good, avoid driving ring and drive both pump housing mechanical sealing device of silicon carbides peculiar to vessel of separating of seat.
Technological scheme to be solved in the utility model is, what provide a kind ofly has a pump housing mechanical sealing device of silicon carbide peculiar to vessel of structure, comprises the stationary ring L pad, the stationary seal ring that are socketed on the axle, moving sealing ring, rotating seat, rubber cup, driving ring; Described moving sealing ring is force-fitted on the stationary seal ring, the inwall of described driving ring and axle close-fitting, described moving sealing ring passes through the rotating seat close-fitting on axle, described rubber cup is located between rotating seat and the moving sealing ring and between driving ring and the axle, and described driving ring and rotating seat close-fitting and both are provided with circumferential limit structure.
Limit structure on described driving ring and the rotating seat refers to, the leading portion outer wall of described driving ring is provided with circumferential polylith the first plane, and the inboard, hole of described rotating seat is provided with for the first plane and matches and the second plane one to one.
Described the first plane and the second plane all distribute along even circumferential.
After adopting above structure, the utility model pump housing mechanical sealing device of silicon carbide peculiar to vessel compared with prior art, have the following advantages: because described driving ring and rotating seat close-fitting and both are provided with circumferential limit structure, the leading portion outer wall of described driving ring is provided with circumferential polylith the first plane, the inboard, hole of described rotating seat is provided with for the plane and matches and the second plane one to one, the first plane matches one by one with corresponding the second plane, both circumferential driven natures of this Placement are also better, be difficult for skidding, and in actual moving process, both close-fittings are firm, even also can avoid both to come off (separation) when frequently beating, thereby guarantee whole mechanical seal normal operation.
