In the port of Liaoning Province, the rotary veeing of No.8 Stark and Recreation Mare was initially issued with a strange sound, and the metallic beams, Sio-Wan, stayed in the port for a long time. This equipment has been in operation for 11 years, and the sound of it is "normal". 3 months later, the rotation was stalled in a clear way, and the machine was stopped by Chiyoda Chihaku. After the disintegration, whoもが冷たい息を吸った:ベアリング轨道面40%のスポーリング面積、ケージ骨折、推定35万嵐から820,000にメンテナンスコスト、ダウンタイムが26日延びた。
These words have been widely circulated in the repair industry of Starka and Recremator. RotaryベアリングStatic and Recreational MapsThe most centrally located high-priced part of this part is the failure of this part, which is the result of an unexpected problem, and the accumulation of warnings that have been ignored.
I. 5 Progress Stages of the Cycloneベアリング Failure
The damage to the rotary veiling is carried out by Yukuri, and the vibration modelling data is classified in 5 different stages:
Stage 1: Wazukanakonaki (6 to 12 months of surgical succession is possible)
Characteristics: The number of cycles that characterise the breakage of theベアリング is the number of vibration spikes, and the amplitude is very small. The acceleration value is usually 0.5 to 1.0m/s² at this stage, according to the data of the project at the power plant.
Treatment: Lubrication is enhanced, lubricationサイクル is shortened from once a month to once every half a month, and EP additives are used to add high-quality grease.![图片[1]-回转轴承深度维修指南:从早期预警到修复完成的126天实战记录(针对“堆取料机回转轴承故障诊断与维修方案”)-大连富泓机械有限公司](https://cndlfh.com/wp-content/uploads/2025/12/QQ20251215-201724-800x530.png)
Stage 2: Medium Degree of Stripping (Recommended for repair within 3 months)
Characteristics: Vibration amplitude is increased and high modulation wave is present. The temperature of the outer wheel of the beam is usually 8 to 12°C higher with the same surrounding temperature and load.
實際のケース:江蘇省のある製鉄所は、この段階でメンテナンスを進めることこと決定し、メンテナンス費用は280000 人民元、ダウンタイムは9日間となった。 もし次の段階まで待っていたら、コストは45万元以上、ダウンタイムは15日以上なる見込みだった。
Stage 3: Profound Damage (Naochi-ni-Suspended)
Characteristics: Cyclic jamming sensation during rotation, unique size. Vibration acceleration value is 4.0m/s².
Stage 4: Causes of failure (possibility of fatal failure)
Characteristics: The pique of the sylphon is generated by vibration, and the sound changes from a continuous sound to a broken sound.
Stage 5: Complete failure (the direction of the machine changes)
We have had a lot of experience in this field. The cement plant in Hunan Province has experienced this and the final repair cost is 18% of the equipment's value.
II. 7 Diagnostic Methods for On-site Practice (Expertise in the use of machines to make judgements)
We have a vibration analyser for all companies, and our experienced instructors are able to make practical judgements on the spot:
Method 1: を聴いて位置を認識する
Long ドライバーか聴診器を使い、もう一方の端を耳に近づけてベアリングハウジングに接触させる。 Normal sound is a uniform "gas gas sound". The "dun, dun, dun" and periodic sound is the possibility of stripping the track surface, the "kata kata, kata kata, kata kata" and the sound is the possibility of a problem with the causeway.
Harbour Master's masterpiece: He was able to judge the damage caused by the sound. He said. "音が最も大きくなるとき、カンチレバーがどの角度を向いているか。" The position of its angle of veering is the place where the damage is done."
Method 2: Temperature Comparison
The temperature of several points on the outer wheel of the vee-ring is measured at the same circumferential temperature and under the same load in the red outer temperature measurement gantry. Normally, the temperature difference is less than 5℃. In case the temperature of the housing is too high, the possibility of damage to the housing is high.![图片[2]-回转轴承深度维修指南:从早期预警到修复完成的126天实战记录(针对“堆取料机回转轴承故障诊断与维修方案”)-大连富泓机械有限公司](https://cndlfh.com/wp-content/uploads/2025/12/QQ20251002-200941.png)
Method 3: Rotary resistance test
The driving motor is equipped with an external drive, a turbocharger, and a rotary mechanism that is manually operated. 360° of rotation is necessary to record the maximum amount of turbocharging. A monthly newsletter and a Versiländerdata have been established. It is necessary to pay attention to the cases where the torque is exceeded by 20%.
Method 4: Grills Status Chick
The oil injection is not only a small amount of oil, but also a small amount of grease that is taken out of the grease outlet and observed. Normal grease is a uniform grease:
Including Metal Sheet: Increase in Dissipation
Change of colour on grey and black: Possibility of water immersion
Block: Grease deterioration or staining
Method 5: Gallery Measurement
Measurement of the rotation of the parser guides. In the case of a 1.5mm overrun of the Crianza, the adjustment of the Prerod is necessary, and in the case of a 2.5mm overrun, the possibility of an aggressive wear and tear of the Beauregard is not possible.
III. 4 Options and Conceptual Analyses of Montranes and Progrms
The need for repair is clear and 4 options are available:
OPS 1: Preroll Adjustment (Minimum Cost)
Applicable conditions: Damage to the shaft or low pre-pressure during prolonged operation.
Method: Adjust the シムthickness and restore the preroduction.
Fee: About 20,000 to 50,000 ドル, 1 to 2 days of download.
Success rate: The state of the reusable is good at 85% or more.
Opus II: Exchange of Damaged Parts (Medium Repair)
Applicable conditions: Damage to the office and other parts are in good condition.
Practical example: The Hangzhou regeneration machine in Tangshan implemented the "Inner Wheel + Full Roller Exchange" programme after the track surface of the inner wheel was partially peeled off.
Fee: 180,000dl (120,000dl for Shinshii Innerring, 40,000dl for rollover, 20,000dl for parts), 6 days for Download Taim.
Important Points: It is important to ensure that new and used parts fit together accurately, and that professional repairers look forward to doing so.
Opus 3: Re-adjustment of theベアリング (Cost-effective Opus)
We have many users who know how to do this. Pro's veiling regeneration business is to regenerate damaged veiling:
Chipping and Grinding of Lesbos
Exchange of all roles and responsibilities
Reheat treatment (surface hardness recovery)
コスト:Approx. 40~60% for new beauty, and 70~80% for new products.
Note: Qualified restoration practitioners should be selected and thoroughly inspected after restoration.
OPS 4: Veoliage Full Exchange (最も完全なもの)
Applicable conditions: Damage to the veiling can be severe, and the damage can be compounded.
Constituent structure (Example: Φ3000mm rotary veiling)
New productsベアリング:250,000~400,000ドル(ブランドによって大きく異なる)
Refting fee: 30,000 - 60,000 dolars
Piece rate: 40,000 - 80,000 dl.
Supplementary materials: 20,000-30,000 dl
Total: 340,000 to 570,000 dl.
Download: 10-20 days (for construction organisations)
IV.Management Portfolio on Maintenance Works
We have traced and documented the entire process of the success of the rotary bridge exchange at the Shandong provincial power station, and managed all 23 portfolios:
Disintegration stage (first 3 days):
Before the disintegration, Doshun had printed and photographed the film.
The order of the bolts is symmetrical between left and right.
The selection of the lifting point is necessary to calculate the centre of gravity in order to prevent deformation.
Measurement of the inches of the old veil after landing, and the basis of the new veil's acceptance.
Setting stage (コア 2 days):
5. Cleanliness of the face of the camera: A white cloth should be used to wipe off any stains.
6. The revolutions are in 3 stages, 30%-70%-100%.
7. After the pretreatment is made, the flatness of the material is measured to be less than 0.2 milimetre per metre, and then every time.
8.The final TORQUE value is for 2 people.
Trial spin stage (after 2 days):
9.30am Giving the temperature to be チェックしながら, less and more than 4 hours without load to test test the turnaround.
10. Experimental loading test by stages: 25%-50%-75%-100% loading.
11. Vibration tests are carried out on all loading levels.
The 3 Most Elaborate Links
Revolutions are made in the order in which they are made: at the ironworks, the revolutions are made in the order in which they are made, the veiling and hurdling are deformed, and the 7-day period is spent on re-processing the veiling and hurdling.
Cleaning of the embedded surface: Fine sand particles are induced by localised stress concentrations, which may cause early damage to the surfaces.
Grease Filling: The new beauty veil is necessary to lubricate the specified grease, and it is necessary to fill the grease several times by completely saturating the grease.
V. Defensive and protective gardens and stadiums
The best models are theノーmaintainers. The average durability of the cyclone beams at the Bentmac Power Plant in China is 16 years, compared to the industry average of 4 years, and the value of the practice is learned from the experience:
Standardisation of daily inspection:
1Day1Record:Soundを聞き、漏れがないかチェックする
Every week: Temperature measurement, lubrication checking
Month 1: Vibration Measurement, Gap Chick
Improvement of lubrication management:
The automatic oiling system is used, and the manual oiling port is disabled. If there is a lot of grease or a lot of good grease, the grease drenches are overflowing with new grease and every time it is refilled, the remaining grease is discharged within 15 minutes after the turnaround time.
Intelligent status monitoring:
The vibration, temperature, and spin resistance are monitored by the realtime operating system. The system is set up with a 3-stage warning level:
ベル 1 アラート (電子メール通知) : パラメータがベースラインを超える 20%
Level 2 Alarm (SMS Notification): Parameter exceeded the reference value 50%
Level 3 Alcatel (Telephone): Parameter exceeds the reference value 1001 TP3T
The decision on the Montanus is finalised:
He has established a soundness scoreboard and system that combines data on vibration, temperature and gas analysis, and has started a soundness scoreboard of 60 and a maintenance preparation programme.
The Ultimate Adobois: Repair of a rotary beacon is a systematic programme of pure disassembly and exchange. When choosing a repairer, we will provide you with information on the contents of the repair, as well as examples of repairs to similar models, complete construction plans, and professional inspection machines. Repairing is successful, so we have been using the VAILINGG for 10 years, or failing to do so for half a year, so we have been able to repair the VAILINGG.
