Abstract
The invention provides a high-temperature high-speed rotary connector. The high-temperature high-speed rotary connector comprises a shell body, an end cover, an outer pipe and a cooling cavity defined by the shell body, the end cover and the outer pipe, wherein the shell body is provided with a flushing connecting port, a plurality of bearings are arranged in the cooling cavity, spacer bushes are arranged among the bearings, a plurality of flow guide rings are arranged in the cooling cavity, and an elastic element is arranged between each bearing and the corresponding spacer bush. The high-temperature high-speed rotary connector increases the utilization rate of cooling liquid, increases the cooling speed, compensates for the axial interval between each bearing and the corresponding spacer bush, prevents the bearings from being damaged, and guarantees that the rotary connector can normally work in a high-temperature high-speed environment.
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 that flowing medium (liquid, oil, gas etc.) is input to the dynamic seal apparatus rotating equipment from static pipeline; to solve run, drip, leak; energy saving, protection of the environment, requisite mechanical seal basis critical component improves working conditions.
Split-type multi-spring-structure rotating joint, adopts split fabricated construction, easy processing, and assembling and easy to maintenance, sealing is steadily.Application number is 201110244316.1, and the patent of invention that denomination of invention is " high-temperature high-speed rotary joint " discloses a kind of Split-type multi-spring-structure rotating joint.This technology has effectively been improved the stuck situation of bearing occurring while carrying high temperature heat conductive oil, but still exists following deficiency: 1, the space of cooling chamber is excessive, causes cooling liquid utilization ratio low, and cooling effect has retardation phenomenon; 2, between bearing and spacer, there is axial clearance, 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 is to overcome existing defect, and a kind of high-temperature high-speed rotary joint is provided, and improves the utilization ratio of cooling liquid, and the axial clearance between compensation bearing and spacer, ensures 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, comprise housing, end cap, outer tube and the cooling chamber being surrounded by three, on described housing, be provided with flushing interface, in described cooling chamber, be provided with some bearings, between described bearing, be provided with spacer, in described cooling chamber, be provided with some guide rings, 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 adopting is high-temperature-resisting corrugated pipe mechanical seal part.
Further, in the tube wall of described outer tube, be provided with heat-insulation chamber.
A kind of high-temperature high-speed rotary joint of the present invention, has improved the utilization ratio of cooling liquid, has accelerated rate of cooling, has compensated the axial clearance between bearing and spacer, prevents bearing damage, has ensured swivel joint normal operation under the environment of high temperature and high speed.
Brief description of the drawings
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification, for explaining the present invention, is not construed as limiting the invention together with embodiments of the present 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, only for description and interpretation 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, comprise housing 1, end cap 2, outer tube 3 and the cooling chamber 4 being surrounded by three, on housing 1, being provided with flushing interface 5 (it should be noted that, the interface of both sides is for rinsing interface, and middle interface is for connecting temperature transducer), cooling liquid realizes turnover thus, in cooling chamber 4, be provided with two bearings 6, between bearing 6, be provided with spacer 7, between bearing 6 and spacer 7, be provided with spring 8, for compensating the axial clearance between bearing 6 and spacer 7, prevent that outer tube from producing axial float.
In cooling chamber 4, be provided with two guide rings 9, be separately positioned on the two ends of cooling chamber 4, not only reduced the space of cooling chamber 4, direct coolant first flows to Sealing 10 and is back to bearing 6 again simultaneously, thereby accelerates rate of cooling.
The Sealing 10 adopting be high-temperature-resisting corrugated pipe mechanical seal part, and heat resistance is strong, and institute's bearing temperature is brought up to 450 degrees Celsius from 170 degrees Celsius of conventional seals part, reduces the spoilage of Sealing, the working life of prolongation swivel joint.
In the tube wall of outer tube 3, be provided with heat-insulation chamber 11, play heat-blocking action.
A kind of high-temperature high-speed rotary joint of the present invention, has improved the utilization ratio of cooling liquid, has accelerated rate of cooling, has compensated the axial clearance between bearing and spacer, prevents bearing damage, has ensured swivel joint normal operation under the environment of high temperature and high speed.
Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
