Description
Technical field：
The invention belongs to steam turbine equipment technical field, and in particular to a kind of steam turbine radial journal bearing temperature measurement structure.
Background technology：
Steam turbine radial journal bearing is used for the load for bearing steam turbine, ensures radial alignment of the rotor relative to stator part.In order to
Steam turbine it is safe for operation, radial journal bearing all designs temperature measurement structure, to detect bearing operation conditions.Measuring temperature of bearing structure at present
Mainly there is survey bearing liner gently to survey two methods of bearing return oil temperature.Surveying the method for bearing liner temperature need to be embedded in sensor in bearing
Portion, the replacing of sensor need to dismantle bearing, are inconvenient.The method for surveying bearing return oil temperature is primarily present error, not
It very can really react the maximum temperature of bearing.
The content of the invention：
In place of the present invention makes up and improved above-mentioned the deficiencies in the prior art, bearing temperature can both be ensured by the temperature measurement structure
Accuracy, while also ensure that sensor is readily disassembled and change the outfit, reasonable in design, securely and reliably, cost is cheap, is easy to advise greatly
Promote and use mould.
The technical solution adopted by the present invention is：A kind of steam turbine radial journal bearing temperature measurement structure, including radial journal bearing and bearing
Case, in addition to temperature transducer, be provided with the radial journal bearing can draw bearing internal layer lubricating oil draw oilhole；The thermometric passes
Sensor, which is connected through a screw thread, to be installed on bearing housing, and the probe of temperature transducer is stretched into and drawn in oilhole.
Beneficial effects of the present invention：Reasonable in design, securely and reliably, cost is cheap, is easy to promote on a large scale and makes
With.The temperature measurement structure can both ensure the accuracy of bearing temperature, while also ensure that sensor is readily disassembled and change the outfit.By in axle
The lubricating oil at perforate extraction bearing minimum oil film on body is held, measures the oil temperature of extraction, the highest temperature of bearing can be objectively responded
Degree.The mounting temperature sensor on bearing housing, realize the separation of temperature transducer and bearing.Bearing temperature can truly be reflected
Degree, while the Quick universal of temperature transducer can be completed in the case where not dismantling bearing.
Brief description of the drawings：
Fig. 1 is the structural representation of the present invention.
Embodiment：
Reference picture 1, a kind of steam turbine radial journal bearing temperature measurement structure, including radial journal bearing 2 and bearing housing 3, in addition to temperature transducers
Device 4, be provided with the radial journal bearing 2 can draw bearing internal layer lubricating oil draw oilhole 1；The temperature transducer 4 passes through screw thread
It is connected and installed on bearing housing 3, and the probe of temperature transducer 4 is stretched into and drawn in oilhole 1.
The temperature measurement structure is calculated by bearing determines that radial journal bearing 2 opens the position for drawing oilhole, draws oilhole 1 by setting, draws
Go out the lubricating oil of bearing internal layer oil film.Temperature transducer 4 is connected through a screw thread on bearing housing 3, the probe of temperature transducer 4
Put in bearing to draw in oilhole 1, the oil temperature that measurement bearing is drawn.Measurement by drawing oil can truly reflect the operation of bearing
Temperature, while temperature transducer separates with bearing, on the premise of bearing is not dismantled, can be rapidly completed temperature transducer 4 more
Change.
