Bảo trì (Maintenance) là gì? Bản chất của bảo trì với doanh nghiệp
Bảo trì (tiếng Anh: Maintenance) là hoạt động chăm sóc kĩ thuật, điều chỉnh, sửa chữa hoặc thay thế một hoặc nhiều chi tiết hay cụm chi tiết máy.
1. Định nghĩa Bảo trì (Maintenance)
Bảo trì trong tiếng Anh là Maintenance.
Bảo trì là hoạt động chăm sóc kĩ thuật, điều chỉnh, sửa chữa hoặc thay thế một hoặc nhiều chi tiết hay cụm chi tiết máy nhằm duy trì hoặc khôi phục các thông số hoạt động, bảo đảm máy móc thiết bị hoạt động với năng suất, tốc độ, tải trọng đã xác định trước.
2. Bản chất của bảo trì trong doanh nghiệp
– Khi đề cập đến bảo trì, nhiều doanh nghiệp cho rằng đối tượng bảo trì bao gồm máy móc thiết bị của nhà xưởng. Nhưng nếu hiểu một cách toàn diện thì hoạt động bảo trì phải được quan tâm ở tất cả các bộ phận liên quan đến hoạt động sản xuất kinh doanh của một doanh nghiệp.
– Đối tượng của bảo trì bao gồm nhà xưởng, mặt bằng sản xuất, máy móc thiết bị sản xuất, thang máy, hệ thống điều hòa không khí, hệ thống máy phát điện, thậm chí cả căng tin và nhà vệ sinh công cộng.
3. Các hình thức bảo trì
Bảo trì bao gồm các hình thức sau:
(1) Bảo trì hiệu chỉnh
– Bảo trì hiệu chỉnh thực chất là việc sửa chữa, hoạt động này được tiến hành khi máy móc, thiết bị ngừng hoạt động.
Ví dụ: Động cơ điện không khởi động, băng tải bị rách hay trục bị gẫy. Trong trường hợp này bộ phận bảo trì ghi lại những sự cố và tiến hành sửa chữa cần thiết. Về lí thuyết, nếu doanh nghiệp chỉ làm công việc hiệu chỉnh thì sẽ là vô nghĩa khi thiết bị đã hỏng và cần được sửa chữa.
– Ưu điểm
• Tận dụng tối đa thời gian sử dụng máy
• Giảm đầu tư ban đầu, không cần có xưởng bảo trì
• Có thể dẫn tới hư hỏng toàn bộ và phải thay thế máy mới
– Nhược điểm
• Thụ động, lịch trình sản xuất không được đảm bảo
• Chi phí sửa chữa cao về nhân lực và phụ tùng thay thế.
+ Bảo trì dự phòng
– Bảo trì dự phòng là tổng hợp các biện pháp tổ chức, kĩ thuật về bảo dưỡng, kiểm tra và sửa chữa, được tiến hành theo chu kì sửa chữa và theo kế hoạch nhằm hạn chế sự hao mòn, ngăn ngừa sự cố máy móc thiết bị, đảm bảo thiết bị luôn hoạt động trong trạng thái bình thường.
– Trái ngược với bảo trì hiệu chỉnh, bảo trì dự phòng được tiến hành trước khi cần sửa chữa và nhằm giảm thiểu khả năng bị gián đoạn sản xuất. Bảo trì dự phòng bao gồm:
• Thiết kế và lắp đặt thiết bị đúng yêu cầu kĩ thuật
• Định kì kiểm tra nhà máy và thiết bị để ngăn ngừa những hỏng hóc trước khi chúng xảy ra.
• Lập kế hoạch sửa chữa nhỏ, vừa và lớn
• Điều chỉnh các bộ phận và tổ hợp máy
• Chăm sóc, bảo dưỡng các thiết bị
• Tra dầu mỡ đúng qui định, lau chùi, sơn nhà xưởng và thiết bị
• Dự phòng trước những sự cố có thể xảy ra thông qua công tác dự báo

No one in the industry or so called experts has analyzed that it is to deal with the problem of fragmentation of the chip being stuck in the neck.Moreover, many so called professional players in China are not paid.

In fact, the demons were not inferior to the Storm Legion in terms of their combat power on paper, and were even higher than it, but in the battle it was a one sided massacre.Zira Countless grasses grow rapidly. Because the growth rate is too fast, even if it is just grass with no fighting power, it will cost Zhao Hao a lot of life.

Li Yuanba lifted the Nascent Soul Dharma. Although he only activated his natal flying sword three times this time, most of his spiritual power was consumed.The proportion of magic weapons that are truly pure and non metallic among magic weapons is very small, which means that the Baidi Sect s invisible magnetism magical power restrains a large part of the magic weapons in the world of immortality.
Li Yuanba shook his head. It was useless to think about these things.If Li Shiming hadn t had a half life cave and realized the process of generating the rules of thunder and lightning in the half life cave, his Jade Pure Thunder Code would not be comparable to the real thunder cultivator.
Even if Brother Zhao Qingfeng was seriously injured, he could easily kill Li Shiming.After receiving the news, he didn t bother Patriarch Liu much and went home while it was still early in the day.
This is not What a good thing. Just when the Nascent Soul Ancestors were thinking about their own thoughts, a fierce sword intent came from the cave nearby, and surging spiritual power soared into the sky along with the sword intent.The formation of the palace was forcibly broken open by the Samadhi Divine Wind and the energy flying sword.
When Li Yuanba showed his great power through the help of Venerable Hongguang, he recalled the injured mid stage golden corpse to his side.He used his Shenmu to observe the formation of Xiaoleiyin Temple, and contacted ibz15, who conducted analysis and research on the formation.

one batch of fourth grade elixir, plus the energy consumption, it would be good for a normal alchemy master in the late stage of the golden elixir to be able to refine one batch in a month.
It was really that the force field controlled by Lingbao Wanjianfeng was too strong.Since his cave does not yet have the ability to solidify the rules, when the thunder and lightning disappear, the rules of thunder and lightning will also disappear, and his thousands of years of efforts will end in failure.
The Innate Jianmu Tree Heart was not a magic weapon at all, but a strange object.But there are very few sword cultivators who can truly study the Broken Void Sword Intent to a very deep level.
Li Shiming had a temporary cave at the headquarters of Zhongzhou Commercial Bank.This is the gap between them and the superpowers. Look at the great monk of the Baidi Sect, he can easily hit the fourth grade top flying needle magic weapon, which means that he has at least two top grade fourth grade magic weapons in his body.

identity jade disk, entered the corresponding information, and gave the identity jade disk to the Great Venerable Hongfa.Go to the library quickly A Yuanying monk quickly reminded loudly.
Jian Lao looked at Xing Yijian with surprise in his eyes.If he really attacks the target on the ground with his thousands of flying swords, he will leave no one alive.
Each fourth grade mountain type magic weapon requires a huge amount of fourth grade refining materials.Several formation masters frowned from the beginning of the formation.
The energy balancing effect of the Nascent Soul. Li Shiming s eyes lit up slightly.This also made the sect s elixir refining tasks more and more delayed.
When the light of Xiantian Yimu magical power fell on his body, he felt the rapid healing of his injuries.As for the appearance of the third grade Muyang Queen Bee, the sect will definitely handle the matter.
Although he was not a top monk, he was the great monk Lei Xiu, who was considered an extremely difficult existence among the great monks.Li Yuanba s combat power makes the sword cultivators extremely convinced.
Only the faint aura coming from a distant direction told him that Li Yuanba was thousands of miles away.This was a flying sword that could threaten the body refining monks in the middle stage of Nascent Soul due to its own quality.
I feel very good. Although my left leg is still a little weak, most of its functions can be restored in ten days at most Brother Hu landed on his feet and swayed slightly before standing firm.
