Abstract
For a ring structure of obturaging for Compressor test part bearing pivot, it is characterized in that: the described ring structure of obturaging for Compressor test part bearing pivot, comprises breathing pipe, ring of obturaging, comb tooth; Obturage ring side surface upper part with breathing pipe mounting hole, and ring of obturaging is inner with vent, and breathing pipe is arranged on mounting hole; Comb tooth and obturage between ring and form annular chamber.Advantage of the present utility model: the ring structure schematic diagram of obturaging for Compressor test part bearing pivot described in the utility model, improves the effect of obturaging of obturage ring and comb tooth, decrease the thermal radiation of high temperature and high pressure gas to bearing.Solve the problem of Bearing Temperature when testpieces working state raises.
Description
Technical field
The utility model relates to mechanical design field, particularly a kind of ring structure of obturaging for Compressor test part bearing pivot.
Background technique
Need the problem considering that bearing pivot is obturaged in engine compressor testpieces structured design process, at present a lot of testpieces adopts fixing ring of obturaging to coordinate with the comb tooth of rotation the sealing configuration formed.When testpieces working state raises, gas temperature and the corresponding rising of pressure, traditional ring structure of obturaging effect of obturaging is undesirable, and the thermal radiation of high-temperature gas simultaneously also strengthens, and causes bearing operating temperatures to raise, affects testpieces work safety, as shown in Figure 2.
Model utility content
The purpose of this utility model is the problem of obturaging to solve bearing pivot, and spy provides a kind of ring structure of obturaging for Compressor test part bearing pivot.
The utility model provides a kind of ring structure of obturaging for Compressor test part bearing pivot, it is characterized in that: the described ring structure of obturaging for Compressor test part bearing pivot, comprises breathing pipe 1, ring 2 of obturaging, comb tooth 3;
Obturage ring 2 side surface upper part with breathing pipe mounting hole 2a, and ring 2 inside of obturaging is with vent 2b, and breathing pipe 1 is arranged on mounting hole 2a; Comb tooth 3 and obturage between ring 2 and form annular chamber B.
During work, introduce one gas by breathing pipe and pass through the breathing pipe mounting hole and vent arrival comb tooth 3 obturaged on ring and the annular chamber B obturaged between ring.The gas temperature introduced because of breathing pipe is lower, flows through in the vent process of circumference distribution, can play cooling action to ring of obturaging at it, and then reduces high temperature and high pressure gas to the thermal radiation of chamber C; Simultaneously breathing pipe introduces gas pressure higher than gas in the A of chamber, gas leakage effectively can be stoped in the A of chamber to chamber C, thus effectively reduce the temperature of bearing 4, improve the Security tested by pressure reduction between the two.
Described comb tooth 3 is divided into two groups, front and back, respectively has three layers of comb toothing.
Advantage of the present utility model:
Ring structure schematic diagram of obturaging for Compressor test part bearing pivot described in the utility model, improves the effect of obturaging of obturage ring and comb tooth, decreases the thermal radiation of high temperature and high pressure gas to bearing.Solve the problem of Bearing Temperature when testpieces working state raises.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is the ring structure schematic diagram of obturaging for Compressor test part bearing pivot;
Fig. 2 is traditional seal structure schematic diagram;
Arrow in figure represents that gas moves towards.
Embodiment
Embodiment 1
Present embodiments provide a kind of ring structure of obturaging for Compressor test part bearing pivot, it is characterized in that: the described ring structure of obturaging for Compressor test part bearing pivot, comprises breathing pipe 1, ring 2 of obturaging, comb tooth 3;
Obturage ring 2 side surface upper part with breathing pipe mounting hole 2a, and ring 2 inside of obturaging is with vent 2b, and breathing pipe 1 is arranged on mounting hole 2a; Comb tooth 3 and obturage between ring 2 and form annular chamber B.
During work, introduce one gas by breathing pipe and pass through the breathing pipe mounting hole and vent arrival comb tooth 3 obturaged on ring and the annular chamber B obturaged between ring.The gas temperature introduced because of breathing pipe is lower, flows through in the vent process of circumference distribution, can play cooling action to ring of obturaging at it, and then reduces high temperature and high pressure gas to the thermal radiation of chamber C; Simultaneously breathing pipe introduces gas pressure higher than gas in the A of chamber, gas leakage effectively can be stoped in the A of chamber to chamber C, thus effectively reduce the temperature of bearing 4, improve the Security tested by pressure reduction between the two.
Described comb tooth 3 is divided into two groups, front and back, respectively has three layers of comb toothing.
Embodiment 2
Present embodiments provide a kind of ring structure of obturaging for Compressor test part bearing pivot, it is characterized in that: the described ring structure of obturaging for Compressor test part bearing pivot, comprises breathing pipe 1, ring 2 of obturaging, comb tooth 3;
Obturage ring 2 side surface upper part with breathing pipe mounting hole 2a, and ring 2 inside of obturaging is with vent 2b, and breathing pipe 1 is arranged on mounting hole 2a; Comb tooth 3 and obturage between ring 2 and form annular chamber B.
During work, introduce one gas by breathing pipe and pass through the breathing pipe mounting hole and vent arrival comb tooth 3 obturaged on ring and the annular chamber B obturaged between ring.The gas temperature introduced because of breathing pipe is lower, flows through in the vent process of circumference distribution, can play cooling action to ring of obturaging at it, and then reduces high temperature and high pressure gas to the thermal radiation of chamber C; Simultaneously breathing pipe introduces gas pressure higher than gas in the A of chamber, gas leakage effectively can be stoped in the A of chamber to chamber C, thus effectively reduce the temperature of bearing 4, improve the Security tested by pressure reduction between the two.
