The embodiment of the application provides a bearing bush temperature monitoring method, as shown in fig. 1, the method includes:
101. and monitoring the bearing temperature data of the target bearing in real time.
Wherein, the bush temperature data refers to the bush temperature data of the bearing. The current execution end can be a control system of the compressor equipment, and can acquire and monitor the temperature data of the bearing bush of the bearing in real time through a temperature sensor arranged at the position of the bearing.
It should be noted that the bearing shell (bearing shell) is a portion where the sliding bearing contacts with the journal, is shaped like a half cylinder with a tile shape, has a smooth surface, and is usually made of an abrasion-resistant material such as babbitt metal. When the sliding bearing works, a thin oil film is required to be arranged between the bearing bush and the rotating shaft for lubrication. If lubrication is poor, direct friction exists between the bearing bush and the rotating shaft, and high temperature is generated, and although the bearing bush is made of special wear-resistant and high-temperature-resistant alloy materials, the high temperature generated by the direct friction is still sufficient for burning out the bearing bush. In addition, the bush may be burned due to the factors of excessive load, excessive temperature, impurities in the lubricating oil, abnormal viscosity and the like, and the sliding bearing may be damaged. Besides, the expression form of the bearing with the overhigh bearing bush temperature comprises the phenomena that the temperature is slowly increased to be close to an alarm value or even an interlocking value, the bearing bush temperature fluctuates irregularly, the bearing bush temperature rises after the load of compressor equipment is lifted, and the like, besides the most direct temperature rise, so that under the condition that the direct temperature is difficult to obtain, whether other expression forms of the bearing bush temperature overhigh can be judged to exceed the standard or not.
102. And if the tile temperature data exceeds a preset tile temperature threshold value, detecting whether the tile temperature data is accurate.
In the embodiment of the application, if the monitored bearing temperature data of the target bearing exceeds the preset bearing temperature threshold (can be specifically configured according to the material of a bearing bush, and can be configured between 95 ℃ and 105 ℃ under a normal condition), whether the acquired bearing temperature data is accurate is firstly confirmed, so that the condition that the running of compressor equipment is influenced due to false alarm is avoided. Specifically, whether the tile temperature data is accurate or not can be detected by firstly checking a wiring terminal of a temperature sensor (such as a temperature measuring resistor) and cleaning impurities such as oil stains, dust deposition and the like; furthermore, when the temperature of the single point is high, the interface of the measurement interface of the current high temperature point and the corresponding other measurement interfaces can be replaced, so that whether the temperature measurement resistance line has a fault or not is judged, and the data of the watt-temperature exceeding threshold value caused by the fault of the temperature measurement equipment is eliminated. In addition, if the resistance line is determined to be faulty, the faulty measurement point may be subjected to forced correction or masking, and the embodiment of the present application is not limited in particular.
103. And if the detection result of the bearing bush temperature data is accurate, starting a bearing bush temperature processing thread matched with the target bearing.
The bearing bush temperature processing thread is used for representing processing schemes adopted under the condition that the bearing bush temperature exceeds a threshold value, such as processing schemes of increasing the amount of lubricating oil, cleaning the surface of a bearing bush and the like. In the embodiment of the application, when the monitored over-threshold bearing temperature data is determined to be in an accurate state, a bearing temperature processing thread matched with a target bearing currently being monitored is started, for example, in order to reduce the influence on the normal operation of compressor equipment, a processing scheme which can be performed under the operation state of the compressor equipment can be firstly adopted for processing, and under the condition that the processing does not reach the target effect, the processing scheme which is performed under the stop state is adopted, so that the condition that the compressor equipment stops operating due to maintenance is reduced as much as possible while the safety of the bearing is ensured.
It should be noted that, because the size, roughness, clearance requirement, load and other parameters of different bearings are different, the bearing bush temperature processing threads adopted by different bearings are in one-to-one correspondence with the bearings. The bearing bush temperature processing thread database can be configured in advance, and relevant parameter data of all bearings to be monitored are stored in the bearing bush temperature processing thread database, so that relevant parameter data of a current target bearing are called and combined with a bearing bush temperature processing thread template, a bearing bush temperature processing thread matched with the current target bearing is generated, and further execution is carried out.
Compared with the prior art, the method and the device have the advantages that when the fact that the tile temperature data of the target bearing exceeds the preset tile temperature threshold value is monitored, whether the tile temperature data are wrong or not is detected, and therefore the situation of monitoring resource waste caused by the fact that the data are wrong is avoided; furthermore, after the fact that the bearing bush temperature data of the target bearing exceeds the standard is determined, a bearing bush temperature processing thread is started to control the bearing bush temperature data of the target bearing, and therefore the bearing bush temperature monitoring is wide and systematic.
For further explanation and limitation, in the embodiment of the present application, the bearing bush temperature processing thread includes an online adjusting thread and a parking rectification thread; the online adjusting thread is used for representing a bearing bush temperature processing thread which is carried out in the running state of the equipment; and the stopping rectification thread is used for representing a bearing bush temperature processing thread which is carried out in the stopped state of the equipment.
In order to minimize the stop of the compressor device due to the maintenance, the bearing bush temperature processing thread may be configured as an on-line adjusting thread and a stop rectification thread. The online adjustment thread can be used for bearing bush temperature processing in the running state of the equipment, and supports maintenance processing on the equipment in the running state of the equipment so as to avoid influencing the running of the equipment; the stopping rectification thread is used for representing a bearing bush temperature processing thread which is carried out in the stopped state of the equipment, and when the phenomenon that the bearing bush temperature exceeds the threshold value cannot be completely processed by the online adjustment thread, the stopping rectification thread is started again so as to further carry out fault processing on the equipment, so that the condition that the compressor equipment stops running due to maintenance is reduced as far as possible while the safety of the bearing is ensured.
For further explanation and limitation, in the embodiment of the present application, if the detection result of the bearing bush temperature data is accurate, starting a bearing bush temperature processing thread matched with the target bearing, specifically including: if the detection result of the bearing temperature data is accurate, starting an online adjustment thread to control the bearing temperature of the target bearing when the target equipment is in a running state; and receiving an ending instruction of the online adjustment thread, acquiring current bearing temperature data of the target bearing, and judging whether the current bearing temperature data exceeds a preset bearing temperature threshold value.
Specifically, if the detected result of the monitored bearing temperature data of the target bearing is accurate, the adjusting thread is started first, specifically including: an oil quantity control sub-thread and an oil control sub-thread. The oil quantity control sub-thread specifically increases oil pressure and increases oil supply quantity on the premise of meeting the oil pressure of the main pipe, so that cold oil entering a bearing is increased, cold-hot oil exchange is accelerated, and the effect of reducing the bearing bush temperature is achieved; and after the oil pressure of the branch pipe is increased, observing the oil return amount in the corresponding oil return sight glass, and if the oil return amount is not increased, detecting whether the isolated gas and the oil smoke in the bearing box are in an excessive state or not and discharging the isolated gas and the oil smoke out in time. The oil product control sub-thread is to detect the lubricating oil mark firstly; and detecting the lubricating oil products, particularly detecting parameters such as antioxidant content, paint film tendency index, air release value, foam tendency and the like one by one. If the overproof parameters are determined, a paint film oil filter can be used for the equipment, and the online cleaning and filtering of oil products are carried out by combining different types of filter cores.
It should be noted that if the rotor and the bearing generate friction during operation, the temperature of the supporting bearing bush will be too high. When the oil supply of the equipment bearing is insufficient and the jacking oil of the equipment bearing cannot jack the rotor, friction is generated between the rotor and the bearing, so that a Babbitt metal layer on the surface of a tile is damaged, the gap of the bearing is changed, and the bearing capacity of an oil film is reduced. In this case, the oil supply amount can be increased by starting the oil amount control sub-thread, and the friction between the rotor and the bearing can be reduced, thereby improving the condition that the bearing bush is over-heated. As another possible case, the lubricating oil grades used in the centrifugal compressor device are 32# turbine oil and 46# turbine oil, and 46# turbine oil is often used, and extreme pressure turbine oil is required to be used for the centrifugal compressor device including the gear box. Therefore, when the lubricating oil grade used by the centrifugal compressor equipment is wrong, the oil films formed at the design temperature are different, which has great influence on the bearing bush temperature, so that when the condition that the bush temperature is high is monitored, whether the lubricating oil grade is used wrongly needs to be detected. Moreover, because the lubricating oil used for a long time is easy to be oxidized, and the lubricating oil is easy to be thermally degraded and slightly burnt due to the action of high temperature in the using process, at the moment, a layer of lubricating paint film is formed on the surfaces of the supporting bearing and the rotor by generated oxides and degradation products, and the generation of the lubricating paint film is difficult to control, so that the lubricating paint film needs to be prevented by a real-time monitoring and processing mode. Therefore, in equipment operated for a long time, parameters such as antioxidant content, paint film tendency index, air release value, foam tendency and the like of the lubricating oil need to be detected, and if the data exceeds the standard, the lubricating oil starts to form or paint films already slowly form. In addition, because the requirement on the performance of the lubricating oil of the compressor is high, the lubricating oil of the compressor needs to be pretreated in a general situation, which specifically includes: 1) Pre-cleaning an oil tank and a valve of a lubricating oil station; 2) Pickling and passivating a lubricating oil pipeline, and removing slag and blowing inside; 3) Cleaning a bearing area and a bearing of the compressor; 4) The oil station is subjected to external circulation for 15-20 days, a filter screen is arranged at the outlet of the pump and in front of the regulating valve, and the filter screen is checked and replaced twice a day until the quantity of soft-point and hard-point impurities in the lubricating oil is qualified; 5) Carrying out multi-point sampling on the lubricating oil after the oil station external circulation is finished, and analyzing the quality of the lubricating oil until the quality is qualified; 6) The compressor is internally circulated for about 7-10 days, and the filter screens are added on the oil inlet pipeline and the oil return pipeline, and the filter screens are checked and replaced twice a day until the quantity of soft point impurities and hard point impurities in the lubricating oil is qualified; 7) And (4) sampling at multiple points after the internal circulation is finished, analyzing the quality of the lubricating oil, and putting the lubricating oil into use after the lubricating oil is qualified.
Further, when an ending instruction of the online adjusting thread is received, the oil quantity control sub-thread and/or the oil product control sub-thread is completed, at the moment, the current bearing temperature data of the target bearing is obtained again, whether the current bearing temperature data exceeds a preset bearing temperature threshold value or not is judged, and therefore whether the target adjusting effect is achieved or not is determined.
As a possible situation, in the embodiment of the present application, after determining whether the current wattage temperature data exceeds the preset wattage temperature threshold, the method of the embodiment further includes: and if the current tile temperature data exceeds a preset tile temperature threshold value, triggering a device parking interlocking event, and starting a parking rectification thread to control the tile temperature of the target bearing when the target device is in a stopped state.
Specifically, if after the on-line adjustment thread is overhauled, the again obtained tile temperature data of the target bearing still exceeds the preset tile temperature threshold, at this time, an equipment shutdown interlock event needs to be triggered, for example, the temperature alarm of the centrifugal compressor support bearing and the thrust bearing is set to 105 ℃, the interlock temperature is set to 115 ℃, the interlock mode is set to one-out interlock or two-out interlock, and a shutdown rectification thread is started to control the tile temperature of the target bearing when the target equipment is in a shutdown state, and the shutdown rectification thread specifically includes: the device comprises a bearing bush trimming sub-thread, a bearing bush mounting sub-thread, a pipeline cleaning sub-thread and an oil inlet hole trimming sub-thread. The bearing bush dresser thread is characterized in that a compressor support bearing is firstly inspected, and whether the surface of a support bearing bush block has coking, scratching, alloy layer falling and other phenomena is detected; if coking exists, cleaning the coking materials, and further detecting the surface of the pad, wherein the coking generally indicates that the bearing is locally overheated in the use process, and the purpose of reducing the temperature of the pad can be realized by increasing the clearance of the bearing and increasing the oil inlet amount of the bearing body; furthermore, the condition that the surface of the tile is scratched and the alloy layer falls off can be treated by manual repair and local repair welding or spare part tiles can be replaced. The bearing bush mounting sub-thread is specifically that parameter data of a current target bearing is called, the thickness of a bearing block is measured by using a spherical micrometer before the bearing block is mounted, and the deviation is guaranteed to be below 0.01 mm; further adjusting the gap of the support bearing to an upper limit value, and processing an adjusting gasket at the back of each bearing tile block to ensure that the removal amount of each tile block is consistent, so that the thickness of the adjusted tile blocks is uniform; and will carry out contact detection with rotor shaft footpath department after the tiling installation, guarantee area of contact and reach more than 85%, if area of contact is not up to standard, can grind the not contact position of tiling. The pipeline cleaning sub-thread is used for detecting the pipe diameter of an oil inlet pipeline and an oil return pipeline of the compressor equipment, the pipe orifice size and whether foreign matters exist or not and cleaning in time. Specifically, the purpose of increasing the oil inlet amount of the bearing is to enlarge the hole through the bearing throttle plug or the oil inlet hole, as shown in fig. 2, the remaining amount of the oil system is further calculated according to the oil consumption of the lubricating oil system and the oil consumption of each bearing, so that the oil consumption increased by enlarging the hole is kept below the remaining amount. As a possible situation, for a large support bearing with a shaft diameter of more than 200mm, as shown in fig. 3, an oil baffle can be added on the basis of a conventional oil inlet hole to efficiently utilize cold oil in combination with a structural form of a plurality of nozzles, so that more cold oil can enter the bearing to increase the lubrication area and the heat exchange efficiency, thereby achieving the effect of reducing the temperature of the bearing.
It should be noted that, because the assembly deviation of the support bearing can cause the situation of the overhigh temperature of the bearing, the clearance is small, the hot oil cannot be discharged in time after the compressor equipment runs, the thickness of the oil film becomes thin, and the overhigh temperature of the bearing is easy to occur in the support bearing; the contact area of the bearing does not reach more than 85%, and the condition that the temperature of the bush is too high can be caused, so that when the support bearing is assembled, the condition can be avoided by detecting parameters such as bearing clearance, bearing contact and bearing interference. Meanwhile, the bearing pads have quality problems, for example, when the surface of the pad has defects of pits, pad, babbit alloy layer falling off, poor swing angle of the pad and the like, the situation that the temperature of the supporting bearing pad is too high can also be caused. In addition, the bearing clearance of the compressor equipment is too small, the wrap angle of the bearing bush block is not suitable to be selected, the bearing preload is too small, the specific pressure of the bearing is too large, and other design defects can also cause the bearing capacity of the supporting bearing to be reduced, and when the rotor runs to the designed rotating speed, the temperature is easy to continuously rise, so that the temperature of the bearing bush is too high.
For further explanation and limitation, in the examples of the present application, the example method further comprises: and receiving an ending instruction of the parking rectification thread, and controlling the target equipment to recover the running state.
In a specific application scenario, the analysis of the cause of the problem of high bearing bush temperature is shown in fig. 4. Reasons that may lead to insufficient oil supply to the bearings include: the oil supply quantity calculation deviation of the bearing caused by the parameter problem or the calculation method problem causes the design of an oil inlet hole to be small, and further causes the condition of insufficient oil supply of the bearing; the oil pipeline and the mailbox are not thoroughly cleaned, and oil impurities are more, so that the bearing is blocked, and the condition that the oil supply of the bearing is insufficient is caused. The reasons that may cause the bearing assembly deviation include: the bearing clearance is small, the bearing interference is large, the thickness of the tile is not uniform, and the contact area does not reach the standard. Oil problems include: the oxidation resistance is reduced, the grade of the lubricating oil is wrong, the lubricating oil is filled with water, the paint film index is large, and the like. The actual operation parameter exceeding comprises the following steps: large axial force, high rotation speed, large load and the like. All the reasons can cause the condition of poor oil film support, and further cause the over-high temperature of the centrifugal compressor bush.
In a specific application scenario, as shown in fig. 5, when the temperature of the centrifugal compressor shoe is too high, the problem analysis shown in fig. 4 can be combined to perform troubleshooting from several aspects of bearing design selection, manufacturing, installation and operation, so as to make a targeted maintenance scheme.
The application provides a bearing bush temperature monitoring method, which comprises the steps of monitoring the bush temperature data of a target bearing in real time; secondly, if the tile temperature data exceeds a preset tile temperature threshold value, detecting whether the tile temperature data is accurate or not; and finally, if the detection result of the bearing bush temperature data is accurate, starting a bearing bush temperature processing thread matched with the target bearing.
