3 sai lầm cần tránh để tăng hiệu quả bôi trơn vòng bi
Ma sát tồn tại xung quanh chúng ta. Nếu thiếu ma sát, chúng ta sẽ gặp khó khăn khi chạy, đi bộ, hoặc thậm chí đứng trên hai chân của mình. Chúng ta cần ma sát để lái xe và bay máy bay; và chúng ta cần ma sát để động cơ đưa bơm hoạt động. Tuy nhiên, trong nhà máy sản xuất, ma sát có thể vừa là bạn và kẻ thù của máy móc thiết bị.
Nếu một phần công việc của bạn là bôi trơn vòng bi máy móc nhà máy, thì bạn biết rõ cuộc chiến chống lại lực ma sát đe doạ sự sống còn của vòng bi cuốn. Việc bôi trơn vòng bi cuốn là một trong những công việc thường bị nhầm lẫn và lạm dụng nhiều nhất trong ngành công nghiệp. Liệu có phải 40% vòng bi không bao giờ sống đủ thời gian thiết kế của chúng và rằng việc bôi trơn kém chất lượng là nguyên nhân hàng đầu dẫn đến điều này ?
Vòng bi cần dựa vào mỡ bôi trơn để giảm mức ma sát. Bằng cách tránh ba sai lầm phổ biến khi bôi trơn vòng bi, bạn có thể dự đoán được thời điểm thích hợp để bôi trơn, biết cần dùng bao nhiêu mỡ, và tự tin về tình trạng tổng thể của vòng bi.
Sai lầm 1 – Bôi trơn vòng bi dựa trên thời gian thay vì tình trạng
Bôi trơn vòng bi mỗi tuần hoặc mỗi tháng có vẻ hợp lý. Sau cùng, việc bảo dưỡng định kỳ vào khoảng thời gian cố định là một khái niệm quen thuộc của bất kì kỹ thuật viên nào.
Vòng bi cần chất bôi trơn chỉ vì một lý do duy nhất, để giảm ma sát. Miễn là chất bôi trơn đang thực hiện nhiệm vụ đó tốt thì chúng ta không cần phải thay đổi hoặc bổ sung thêm. Tuy nhiên, chúng ta thường làm điều đó định kì với kết quả thảm họa.
Bôi trơn vòng bi chỉ vì lịch của bạn nói “đã đến lúc!” là sai lầm đầu tiên. Theo dõi, đo lường và theo dõi mức độ ma sát bằng siêu âm để biết khi nào là thời gian thích hợp để bôi trơn chính là cách làm chính xác nhất để công việc bôi trơn thật sự diễn ra đúng lúc và đúng thời điểm.
Sai lầm 2 – Quá Nhiều hoặc Quá Ít Mỡ Bôi Trơn
Sai lầm thứ hai mà chúng ta cần tránh là thêm quá nhiều hoặc quá ít mỡ. Quá nhiều mỡ tạo áp lực, đẩy các phần tử cuốn qua lớp dầu và đẩy chúng chạm vào bề mặt ngoài. Vòng bi bây giờ phải làm việc nhiều hơn để đẩy các phần tử cuốn qua một bãi bùn dầu mỡ.
Ma sát và áp lực tăng lên từ quá nhiều mỡ làm tăng nhiệt độ bên trong vòng bi. Nhiệt độ quá cao có thể làm giảm hiệu quả của chất bôi trơn và làm cho dầu tách ra khỏi chất làm đặc.
Ngược lại, không thêm đủ mỡ cũng có hiệu ứng rút ngắn tuổi thọ tương tự.
Vậy làm thế nào chúng ta biết khi đã thêm đúng lượng chất bôi trơn ?
Bằng cách theo dõi mức độ ma sát bằng siêu âm khi áp dụng mỡ mới – từ từ, từng lần một. Lắng nghe vòng bi và đo sự giảm ma sát khi mỡ chảy vào vòng bi. Khi mức độ đạt tới một giá trị tối thiểu và ổn định, hãy chú ý. Thêm từng lần. Nếu mức độ âm thanh bắt đầu tăng một chút thì dừng lại! Đó chính là cách để xác định chính xác lượng chất bôi trơn mà vòng bi của bạn cần.
Sai lầm 3 – Đánh giá hiệu quả bôi trơn vòng bi bằng cảm nhận chủ quan
Như bất kỳ công việc nào, có cách đúng và cách sai để thực hiện. Chỉ nghe vòng bi bằng thiết bị siêu âm mà không cung cấp thông tin đo lường là một sai lầm thường dẫn đến hiệu quả kém.
Phản hồi từ âm thanh của thiết bị siêu âm là quá chủ quan để đưa ra bất kỳ kết luận so sánh nào. Không có hai người nào nghe giống nhau và không cách nào để nhớ rằng tiếng vòng bi nghe như thế nào một tháng trước đó.
Sai lầm thứ ba là phụ thuộc hoàn toàn vào việc chỉ dựa vào âm thanh siêu âm chủ quan thay vì các dữ liệu trực quan khác. Vì vậy, luôn sử dụng một thiết bị siêu âm với máy đo âm thanh số cụ thể. Tốt hơn, sử dụng một thiết bị cung cấp nhiều chỉ số về tình trạng.
Các chỉ số Max RMS và Peak dB chỉ ra các mức cảnh báo và khoảng thời gian bôi trơn trong khi Hệ số Ultrasonic Crest Factor cung cấp thông tin về tình trạng vòng bi liên quan đến mỡ bôi trơn. Hệ Số Peak, and Crest Factor giúp chúng ta phân biệt giữa vòng bi cần mỡ và vòng bi cần phải thay thế.
Lợi ích rõ ràng khi tránh ba sai lầm
Việc sử dụng siêu âm để hỗ trợ bôi trơn tài sản máy móc cung cấp lợi ích đáng kể mà bôi trơn dựa trên lịch trình không thể mang lại. Bôi trơn phục vụ mục tiêu chính là tạo ra một lớp mỏng của chất bôi trơn giữa các phần tử trụclăn và trượt giảm ma sát. Vì vậy, công việc này sẽ hiệu quả khi xác định yêu cầu bôi trơn của máy móc là bằng cách dõi mức ma sát của vòng bi.
Tối ưu hóa việc bôi trơn máy móc cơ sở bằng siêu âm sẽ dẫn đến việc giảm lượng chất bôi trơn sử dụng đáng kể. Việc có một hệ thống siêu âm tốt có khả năng phân tích nhiều số liệu và đồng bộ chúng với cơ sở dữ liệu của phần mềm quản lý bảo trì CMMS sẽ giúp tạo ra văn hóa tốt hơn bao gồm việc bảo quản sạch sẽ, lấy mẫu, và tránh sự kết hợp của các loại dầu mỡ khác nhau.
Máy móc được bôi trơn đúng cách đòi hỏi ít năng lượng hơn để hoạt động. Hãy tưởng tượng rằng việc giảm lượng tiền tiêu cho mỡ sẽ dẫn đến hóa đơn năng lượng thấp hơn. Máy móc tiêu thụ ít điện năng hoạt động mát hơn và máy móc hoạt động mát hơn có tuổi thọ dài hơn.
Cuối cùng, bằng cách theo dõi tình trạng bôi trơn của máy móc của bạn, bạn cùng lúc đó đang thu thập dữ liệu tình trạng quý báu về máy móc. Dữ liệu siêu âm động và tĩnh kết hợp với các chỉ số tình trạng như tổng RMS, tối đa RMS, Peck và Crest Factor đều là các chỉ số về tình trạng của vòng bị.
Bây giờ bạn đã biết rằng có thể có nhiều lợi ích tốt từ một sự chuyển đổi đơn giản từ lịch sang bảo dưỡng dựa trên tình trạng

This Heaven reaching Spirit Treasure, the Great Rijing Wheel, is the most powerful treasure of the Sunset Demon Lord s body.Seeing this, Xu Yang thanked the phantom, and entered the space passage together with Wang Lin and disappeared.
Suddenly, Li Chengzu had a very bold idea. He wanted to snatch Du Heng over and take him to the Orthopedics Department.Brother Gong, do you think the earth won t explode if the weather is so abnormal Du Heng suddenly had a nonsensical idea in his mind and couldn t help but ask.
The effect is very good, Dr. Du. It s even better than the recovery after our internal fixation.Most of the hands and hands suffered superficial second degree burns with many blisters.
Du Heng kept looking around, looking at the vast white area and the traces of rolling.Looking at the half finished meal, Li Jianwei laughed, What s going on, let s go there Du Heng also smiled softly, Check Out Easy 9926 Hemp Recipes Isn t the table being cleared It s not being cleared.
The table is full The beard is messy The beard is dripping and the traces are rejected The beard is dripping The test is allowed to support the instructions The beard is warm and steaming, the branches are worried and green.Is this because I feel that my life is too comfortable, or do I think that after I finish my practicing exam in the middle of the year, the health center will definitely want me He glanced at Zhang Shuai who was digging a hole for him, and quickly stood up and caught up with Han Yujian, Thank you, Teacher Han, or I.
Okay, go do your job. The young man smiled gratefully and left quickly.
Seeing Wu Buwei s expression at this time, he laughed out loud, I don t, you are only six years older than me.Now that I think about Indulge In The Bliss Of Agl Strawberry Thc Cbd Gummies 59 A Comprehensive Guide Ycssk it, the damage to Amei Liu s liver function caused by this is not a problem of ovarian cancer, but a problem of stillbirth.
But before these people left, they mentioned an issue that caused headaches for both Du Heng and the district bureau, that is, if they want to upgrade the second level hospital, the composition of the hospital s doctors and the number of directors and deputy directors are also mandatory conditions.
Du Heng had no choice but to continue, You said it yourself before, Yang Ming s disease is really the same as the Wei family.Wu Zhong sitting in front of the hospital bed were left in the ward.
She thought she had discovered something very funny, and she would still chuckle from time to time until the next day when she and Du Heng went to the health center.When something happens, the two of them can work together and support each other.
There was no support throughout the whole process, just like going through normal hospitalization procedures.Wu Shengnan s mother burst into tears and asked Du Heng in a trembling tone, Is there no possibility of saving it I can only say that I will try Finding Restful Sleep With Olly 8573 Sleep Gummies Milligrams A Comprehensive Guide Gkgjf my best, but I can t guarantee how many toes I can save in the end.
And these doctors and nurses, in almost a year, have really become accustomed to it.But compared to doing an examination Taking films requires a lot of time.

After Du Heng finished speaking, Zuo Liangliang patted his thigh, This is good, this is a good thing.They are not afraid of retribution. Hey, you don t know, their family has already suffered retribution.
Du Heng thought for a moment, looked at Xiao Li who was following Yu Haiting, and shouted quickly, What is the name of the man who came with you, Liu Xiao Li quickly replied, Dean, his name is Liu Shuaijun.Of course, for cars priced under RMB 100,000, there is not much to choose from.
He is 75. He suddenly suffered from hemiplegia in the second half of last year.Generally speaking, it is simple and bland, like a glass of warm water, bland but very comfortable.
Li Jianwei also played a trick and directly called Du Heng Xiao Du to close the distance between them.Then I ll take you there. No, Qiuqiu and Du Yi haven t eaten either.
Wang Shuqiu really felt Du Heng s kindness, and her tense mood really relaxed, I have had a problem since I was a child.Apply to a big hospital Du Heng couldn t accept this path of work, and few hospitals wanted him as a health center doctor.

When she heard the child s mother said that the child had a high fever, she had already put a thermometer on the child before going upstairs to The Benefits Of Spring Valley Adult Gummy Probiotic A Comprehensive 93 Guide Bzaug call for help.The Magazin Incident happened at that time. I felt that everyone in the dormitory was not a good person, especially one of our classmates who looked very similar to that person.
Thinking about it now makes me laugh to death. I started studying educational psychology, and later I read about the psychology of mutation and criminal psychology because of my interest, but I only had a brief taste of it, and I couldn t stand it after turning through dozens of pages at most.
Dong Yuezhang thought for a while and said first, It s not common sense to push people with conflicts to good units.Du Jiang had no choice but to clarify, It s a little inconvenient.
When she and Wang Shuqiu stand together, they give people two different feelings.My own experience. Wang Zhenzhen looked at Du Heng in disbelief, but she couldn t figure out why.
Du Heng continued, Actually, it is still The best way is to take a warm bath.Look at this chicken, it s real meat, but there s no potatoes, radishes or the like.
feel.

And he has begun to gradually master the essence of martial arts if you want it, don t want it, if you don t want it, you want it.Jiao, why treat it from below and heal it from above Secondly, Ligusticum chuanxiong is a yang medicine, how can it still be effective when it is put into yin Dr.
The older ones thought the doctor said, Why don t you think about it If the public medical system is abolished, then gold dollar medical care, excessive medical treatment, High priced medical care will be rampant.Are you a nymphomaniac Gong Daoyang laughed playfully.
But Du Heng and others frowned when they looked at the gloomy sky.Unknown. Jin Zan calmed down his emotions a little.
In fact, not only Wang Qingpeng was curious, but Guan Bo s parents outside the ward, and Zhang Dewen were also curious now, and they all stared at the junior.At this time, the young man suddenly asked, Did we be exposed and make the suspect alert Wu Shengnan still shook his head slightly, This is even more impossible.
Our hospital has now entered the fast lane. Things like today will definitely happen again in the future.Either the medication is inaccurate, or more medication is prescribed, which disrupts the overall treatment rhythm, making the treatment slow or not effective at all.
Du Heng took a deep breath and said with a straight face, People have two qi, yin and yang.He just asked if he had a cold, checked his pulse, and left with the medicine.
Madam, did you admit the wrong person Du Heng was stunned for a moment, and as the checklist fell from his face, he also frowned.Ah Wu Shengnan shouted angrily, Are you going to say that you don t want Best Cbd Gummies For 30235 Hip Pain Relief Benefits Science And Reviews to get this certificate Yes, of course I do.
He took the prescription and walked to the computer.The disgust in his eyes became even more intense for a while.
Wu Shengnan acted coquettishly , and then said cheerfully, It s okay now.I m afraid your side The doctor is not very accepting of our therapy.
I m angry. Du Heng nodded clearly, It s normal to be angry.If your mother in law hadn t helped you, you might have been in a much worse situation than you are now.

These people were all busy people, and it was impossible for them to come to the health center in a group just to see someone who was insignificant to them.In order to get the paper quota or the employment quota, which one is not Understanding The Benefits And Effectiveness Of 90 Earthmed Cbd Gummies obtained by breaking one s head But look at Du Heng now, who used the first six years to lay the groundwork, and then was promoted year by year.
Was it their decision that he would not be able to survive without a replacement It was them, and they were the ones Just Cbd Gummy 87 Worms who screamed the most fiercely.If it were in the past, if he said it right, Du Heng would say it clearly.
But he still had one thing to figure out. Thinking of this, Wu Buwei continued to ask, Dean, why does this man have breast nodules Hearing this question, Du Heng hesitated and was not in a hurry to answer Wu Buwei.I won t stop you and will sponsor you. However, your current results are not enough for you to go wandering.
I found that Zhang Dewen was more liberal than Lan Changhua.Uncle, I came to you to help me, not to let you scold me.
