Để đảm bảo hoạt động liên tục, hiệu quả của máy móc, thiết bị góp phần quan trọng trong việc duy trì tính ổn định quy trình vận hành sản xuất của các doanh nghiệp thì việc bảo trì bảo dưỡng hệ thống máy móc là việc làm rất cần thiết. Tuy nhiên cân nhắc lựa chọn loại hình thức bảo trì để có thể tiết kiệm chi phí mà vẫn đảm bảo thiết bị hoạt động tốt luôn là việc khó khăn đối với các nhà quản lý thiết bị.
1. 3 phương pháp bảo trì phổ biến tại Việt Nam
Hiện nay có 3 phương pháp phổ biến được áp dụng để bảo trì máy móc thiết bị:
1. Bảo trì máy móc thiết bị định kỳ:Dựa trên những thông số kỹ thuật của nhà sản xuất và tình trạng sử dụng thiết bị để đưa ra kế hoạch bảo trì và thay thế các chi tiết máy theo lịch cố định.
2. Sửa chữa, bảo trì sau khi máy móc/thiết bị bị hỏng: Sử dụng máy cho tới khi hỏng và chỉ thực hiện các công tác bảo dưỡng đơn giản như tra, thay dầu mỡ, sửa chữa, tân tạo lại máy sau khi hỏng.
3. Bảo trì theo tình trạng máy:Tình trạng máy sẽ được kiểm soát định kỳ. Chỉ lên kế hoạch dừng máy để xử lý dung sai (ví dụ độ lệch tâm hay mất cân bằng), hoặc thay thế, sửa chữa sau khi chẩn đoán chính xác tình trạng máy trước khi máy hỏng.
Việc xem xét để đưa ra phương pháp bảo trì phù hợp cho từng loại máy móc là không hề đơn giản khi phải tính đến những yếu tố như thời gian sử dụng máy, vai trò sử dụng của máy, chi phí bỏ ra khi mua máy móc,…
Trên thực tế, những chi phí bảo trì gián tiếp gây ra do thiết bị hư hỏng đột ngột, thiệt hại do tuổi thọ máy giảm, thiệt hại về năng suất, thiệt hại do an toàn và môi trường lao động kém,… lớn hơn nhiều so với chi phí bảo trì nếu như phát hiện sớm và ngăn ngừa hỏng hóc xảy ra.
2. Bảo trì phòng ngừa - giải pháp bảo trì hiệu quả tại Việt Nam
Kết hợp bảo trì dựa trên tình trạng máy và bảo trì định kỳ hay còn gọi là Phương pháp bảo trì phòng ngừa (PM) sẽ giúp giải quyết vấn đề này.
Bảo trì phòng ngừa (Preventive maintenance – PM) là phương pháp bảo trì cân bằng giữa 2 yếu tố: thời gian bảo trì thiết bị định kỳ và việc kiểm tra theo dõi thiết bị, hoạt động PM sẽ kết hợp bảo trì với việc lưu giữ thông tin thiết bị. PM sẽ lưu giữ thông tin về các bất thường được tìm thấy của thiết bị từ đó dự đoán trước để ngăn chặn hỏng hóc và lỗi máy trước khi chúng xảy ra bằng cách thực hiện theo thủ tục bảo trì thường xuyên và toàn bộ. Mục tiêu là ít hơn, thời gian ngắn hơn và có thể dự đoán được hỏng hóc phải ngừng máy.
Những lợi ích của Bảo trì phòng ngừa (PM)
Khi thực hành đúng cách, PM sẽ ngăn ngừa hầu hết các vấn đề lớn, do đó giảm ngừng máy đột ngột, giảm chi phí thay thế phụ kiện, bảo trì khi máy hỏng.
Đảm bảo thiết bị đang được hoạt động tốt, không ảnh hưởng tới sản xuất.
Kéo dài chu kỳ sống của thiết bị và các phụ tùng thay thế cho thiết bị.
Tuy vậy, Bảo trì phòng ngừa cũng có 1 số hạn chế
Tốn một chi phí tiền bạc và thời gian nhất định.
Không cân nhắc điều kiện thực tế của thiết bị khi lên kế hoạch và thực hiện bảo trì.
Hư hại thiết bị khi bảo trì không đúng cách.
Trong nền sản xuất công nghiệp hiện đại, Bảo trì phòng ngừa đã được chứng minh giúp tối ưu chi phí khi chỉ phải bỏ ra một khoản chi phí về tiền và thời gian có giá trị nhỏ so với những lợi ích thu được một cách gián tiếp khi ngăn ngừa hỏng hóc. Hơn thế nữa, Bảo trì phòng ngừa sẽ đảm bảo độ tin cậy của thiết bị và là phần quan trọng nhất trong công tác bảo trì thiết bị.

Zhenjun Gan Yan also has a skill in speaking, he called the other party a junior when he came up, and immediately took the initiative.Just like that, after two full hours, all the formation disks in Shao Nan s hands disappeared.
Of course the rest is given to the senior.The senior not only saved the junior s life, but also gave the junior a chance to escape.Because the Inspector Elder said exactly.There is no obligation, except for trying Dose Science The Love Nbxo For For Perfect Ed Mg Gummies Cbd to save the sect from the fire and water when the sect is in danger, other things can be indulged.
When the city lord learned that the two Void Returners were leading people to fight against the Bibo Huanyue Clan, the uneasiness on his face disappeared instantly.Shao Nan, who was thinking about the problem of Jin Duo refining, suddenly changed his expression, a little surprised.
When the water is clear, there will be no fish, and there will be shadows everywhere.With a tap of his toes, his body bounced diagonally backwards, and the Baihong Sun Sword stabbed in the direction of the attack without any hesitation.
That girl from the Fu family looks more interesting, Jie Jie Senior Xie Luo in the carriage laughed wildly.With Shao Nan s years of experience, it is not easy to deal with these youngsters.

To be continued.Chapter 422 Nanpu Zichang Prefecture, Zhugu Lake.Shao Nan doesn t have much time now, and now there are only two options, one is to refine the fire spirit dragon, which seems impossible now.
Unlike the white light of the gentle fire test, the angry fire test is a red light.The Golden Core monks who were eager to try just now are all honest.
As for my clansmen, I guess they have all been murdered.What Dacheng Fire Spirit Dragon You are really messing around.
Xu Dalang pinched his horse s belly Efficacy Feedback Consumer Blue Bfsatil For Their Review A Gummies And Of Ed and rushed to Donghuamen with his horse s hooves, but was stopped by a line of guards.Write quickly Xu Qi an pushed him.Xu Erlang woke up like a dream, and quickly finished writing with a sullen face.

However, this would not cause immediate death.And this little flag official died lying on the desk without struggling or letting blood spatter.Xu Nian lacked this kind of awareness, but he was smart, and immediately got what his cousin meant, and clasped his fists at everyone, I m Xu Ping an, a student from Changle County.

The door is unlocked, come in The man in black responded with a low voice.Xu Qi an sighed inwardly.Some regret that their mathematics, physics and chemistry are not good enough to carry out farming activities in this era of backward infrastructure and material scarcity.
Hearing Eunuch Liu s words, the officials of the Ministry of Punishment thought that the other party was embarrassing the little Tongluo surnamed Xu.Yang Yan stared at Xu Qi an for a moment, it was insignificant nod.
County Magistrate Xu Qi an and Zhu were the first to react It s him.I ll help Second Uncle Xu couldn t sit still anymore, got up quickly, and strode out.
He stared blankly at his cousin, wondering if it was an illusion, Xu Erlang seemed to see the dense purple air on his cousin s head disappearing in a flash.I.Aunt sniffled and lowered her head to cry.Xu New Year looked at her mother who had always been strong.
As he ate, the young man felt a little empty for some reason. The young man thought about it carefully, could it be because he felt sorry for the copper coins Chen Pingan ate the candied haws that he had not tasted for nearly ten years, and carried the locust tree branches back to Mu Ping Alley.Cui Shan sat on the chair by the pool, opened the wine bottle, and smelled it. then turned around and smiled Even if there is only a trace of residual soul left, it is not the behavior of a gentleman to break into a private house uninvited.
Too deep. Chen Pingan asked doubtfully Is Luolu Mountain Gafnfphi Male Reviews Royal Benefits And Honey Enhancement weird The old man For And Gummies Ed Reviews Evaluating Results Cbd Effectiveness Qjxf hesitated, blew out a smoke ring, and nodded, Apart from Piyun Mountain and Xiangshan Mountain, Luolu Mountain is the most interesting.The old land man seemed to be drooping his head in despair, but in fact, his eyes never stopped.

As a result, the business of the inn and restaurant is booming. At the same time, on Fulu Street and Taoye Lane, many young people of this generation from wealthy families began to leave the town quietly.She opened the ancient book she borrowed from her son and began to search for it according to the pictures.
The old ape hummed, Please help take care of Miss this time, even if Zhengyang Mountain owes you a favor.The woman was overjoyed, with tears in her eyes, hugging the child, and murmured in detail The child s father, have you heard, we Gu Can will definitely have a great future.
Liu Zhimao suddenly let out a cry of surprise. He opened his eyes and looked down at the lines on his palms.
Certain people and things, even the scenery on the roadside, will still make people feel beautiful just by looking at them.When I was a kiln worker, I used this for all the cuts and bruises. It has proven to be effective. It was a secret recipe told to me by an old man in Yang s shop a long time ago, but I promised him not to do it.
After you pick up the stones and return to my yard, wait for the lady to find you. That s the one. The woman whose son is wearing a bright red dress, the mother and son we saw at the entrance For Enhancement The Station Male Pills Best Wrnd Gas of Mud Bottle Alley last time, when she comes to your door, don t say anything, just hand her the big box and she will give it to you.
Instead, he retrieved the slingshot and a bag of stones from the window sill. The reason why he did something he knew he couldn t do but still didn t regret it even after hitting the wall three times in a row is the unique tenacity of a young man.Cui Zhang stretched out a finger and pointed at Old Man Yang tremblingly. He almost burst into tears with laughter and said sarcastically Although I, Cui Zhang, am not as good as my husband or Qi Jingchun, but for the so called immortal golden body, As a result, I was treated as a lackey who looked after the house and the courtyard.
Like a living flame dragon wrapped around the girl s wrist. The Gummies Behindthescenes Product Insights Shark Episode Tank And Ohonsm Review Ed man said happily I finally have some conscience.mean. The Taoist opened his eyes slightly, and seeing that he was about to miss the business again, he had no choice but to slap his hand on the table and raise his voice, The number one scholar is a son of the human world, and the prime minister is just a human being.
The maid Zhigui did not turn her head, but she showed a trace of nervousness. Song Changjing smiled and said For the four words written on the plaque on the corridor bridge, I, Dali, have paid a price so high that outsiders cannot imagine it.Qi He hesitated for a moment, Butt Nccamel The Gummies Way Your Npnlm Enhancement Curves Natural To Achieve but explained It is said that Mr. Qi fell into disgrace after his mentor. After that, my realm fell and my mood was broken, so I agreed to be relegated to this small world.
I once killed one with my own hands. At that time, I was only a seventh level martial artist, and that person was a relatively difficult swordsman.The last one must be interesting and have good talent. It s very interesting to have a good And Regen User Gummies For Feedback Ed Results Wjumm Cbd Analyzing foundation and be good at everything.
I just ask the Taoist Master to write the talisman on the yellow paper better than usual, okay The Taoist smiled.From another place, a gentle voice reminded hurriedly No, it s Ruan Qiong s natal wind and thunder swords Lan Ting, retreat quickly Ruan Qiong s natal thing is different from ordinary people and is not stored in the acupoints.
After hesitating for a while, he actually turned around and returned to the official office. On Fulu Street, a burly old man with white hair led a girl with a delicate face like a porcelain doll.This shows how important this town is. Turning it over, there were only two Ed Gummies Otter For Solution Ultimate Are Jqf The Cbd Green They words engraved on the back of Yugui.
The woman s lips trembled, trying her best to suppress her emotions. Surprise, a pair of watery eyes also exuded a bit of seductive charm.Its gloomy eyes were fixed on the girl Zhu Lu. spitting out letters again and again, and thick white snake saliva kept falling down, it was like a gourmet coveting a delicious dish.
However, the maids and grandmothers in our family really walked like cats and could not hear any sound.Chen Pingan said helplessly It s useless. People who fish with bamboo sticks The fish in our stream are actually not big.
Moreover, Emperor Dali promised This place will be enshrined in the future with a mountain god, three mountain gods and a river god.Regarding the flying swords, the old man said doubtfully Master Ruan, my house also has several good quality messenger flying swords.
Master Ruan smiled and waved his hand, They are different, the difference is not small. The old man immediately understood. However, Nan Yan said Talking about flying swords in front of Master Ruan makes you laugh.
Where is their family s grave Liu Xianyang talked about you, saying that you are now the person in the town who is most familiar with the surrounding landscape.Chen Dui smiled and nodded and said, Steward Xue is a sensible person. No wonder the government office runs smoothly. The old Or Penguin Gummies Rpewa Ed Hype For Relief Cbd Cool steward smiled broadly and said, Miss Chen is ridiculous.
This heirloom of my Liu Xianyang , which is also unique in the town. The girl in the curtain hat waited for Chen Ping an, looked around, and finally placed the long sword horizontally on an old cabinet painted with golden flowers.The girl curled her lips, how could she be so brave In the house on the A Gummies Best Cbd Ed Places Buying To Guide Purchase For Ihitrt far west side of the town, a woman sat on the ground and cried loudly, beating her chest vigorously and swaying.
Mr. Qi s situation in the school is quite difficult now, and Mr. Qi and my father have handed over When the time comes, it is very likely that the town will usher in an earth shaking new situation.You forgot that Lizhu Cave has just been opened. It s strange that you know it. It doesn t matter, it doesn t matter, we can talk slowly, there s plenty of time.
Apart from anything else, if he kills someone, although the old man will be expelled by the saint, but compared to being silently killed, it is like dropping a bullet into the water.The girl frowned, without turning her head, and said one word from between her teeth, Get out Another whoosh.
So let me see, Da Li Chao Ye said that although Liang Song is your disciple, he is better than his master, and he is not wronging you at all.Our military strategist is an authentic swordsman A sword that can be cultivated can defeat all methods, and a sword that can be cultivated can obey the rules.
The Song family has always been kind to Qi practitioners, but the premise is that these Qi practitioners , I must work hard for the Song family, even if it s just a show.As long as you reach that point, you will naturally have a clear understanding. It is difficult for outsiders guidance to be effective, and the real Guidance is never based on the principle.
even Liu Xianyang, who has a natural sword embryo, can t compare. In the past millennium, few people in the town can match it.She shook her head and clicked her tongue, as if she happened to catch it. A couple of dogs and men. She walked alone in Mud Bottle Alley, jumping up and down.
