Description
Technical field
The present invention relates to a kind of high-temperature high-speed rotary joint, belong to mechanical part field.
Background technique
Swivel joint is flowing medium (liquid, oil, gas etc.) is input to rotating equipment dynamic seal apparatus from static duct; solve run, drip, leak; energy saving, protection of the environment, improve working conditions requisite mechanical seal basis critical component.
Split-type multi-spring-structure rotating joint, adopts split fabricated construction, easy processing, assembling and easy to maintenance, and sealing is steady.Application number is 201110244316.1, and denomination of invention is that the patent of invention of " high-temperature high-speed rotary joint " discloses a kind of Split-type multi-spring-structure rotating joint.The stuck situation of bearing that this technology effective occurs when improving conveying high temperature heat conductive oil, but still there is following deficiency: 1, the space of cooling chamber is excessive, and cause cooling liquid utilization ratio low, cooling effect has retardation phenomenon; 2, there is axial clearance between bearing and spacer, easily produce outer tube axial float phenomenon, cause bearing damage.Based on above-mentioned two defects, swivel joint in use, cannot bear the Environmental Conditions of high temperature and high speed.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of high-temperature high-speed rotary joint, improves the utilization ratio of cooling liquid, compensates the axial clearance between bearing and spacer, ensure the stable use under high temperature and high speed state.
In order to solve the problems of the technologies described above, the invention provides following technological scheme:
A kind of high-temperature high-speed rotary joint, the cooling chamber comprising housing, end cap, outer tube and surrounded by three, described housing is provided with flushing interface, some bearings are provided with in described cooling chamber, spacer is provided with between described bearing, be provided with some guide rings in described cooling chamber, between described bearing and spacer, be provided with elastic element.
Further, described guide ring is two, is separately positioned on the two ends of cooling chamber.
Further, the Sealing adopted is high-temperature-resisting corrugated pipe mechanical seal part.
Further, heat-insulation chamber is provided with in the tube wall of described outer tube.
A kind of high-temperature high-speed rotary joint of the present invention, improves the utilization ratio of cooling liquid, accelerates rate of cooling, compensate for the axial clearance between bearing and spacer, prevent bearing damage, ensure that swivel joint normal operation under the environment of high temperature and high speed.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of high-temperature high-speed rotary joint of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of high-temperature high-speed rotary joint, the cooling chamber 4 comprising housing 1, end cap 2, outer tube 3 and surrounded by three, housing 1 is provided with flushing interface 5 (to it should be noted that, the interface of both sides is for rinsing interface, and the interface of centre is for connecting temperature transducer), cooling liquid realizes turnover thus, two bearings 6 are provided with in cooling chamber 4, spacer 7 is provided with between bearing 6, being provided with spring 8 between bearing 6 and spacer 7, for compensating the axial clearance between bearing 6 and spacer 7, preventing outer tube from producing axial float.
Be provided with two guide rings 9 in cooling chamber 4, be separately positioned on the two ends of cooling chamber 4, not only reduce the space of cooling chamber 4, guide cooling liquid first to flow to Sealing 10 simultaneously and be back to bearing 6 again, thus accelerate rate of cooling.
The Sealing 10 adopted be high-temperature-resisting corrugated pipe mechanical seal part, and heat resistance is strong, and institute's bearing temperature brings up to 450 degrees Celsius from 170 degrees Celsius of conventional seals, reduces the spoilage of Sealing, the working life of prolongation swivel joint.
Be provided with heat-insulation chamber 11 in the tube wall of outer tube 3, play heat-blocking action.
A kind of high-temperature high-speed rotary joint of the present invention, improves the utilization ratio of cooling liquid, accelerates rate of cooling, compensate for the axial clearance between bearing and spacer, prevent bearing damage, ensure that swivel joint normal operation under the environment of high temperature and high speed.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
