Planned production shutdown and maintenance content
Thread Content
Chemical companies have planned shutdowns for maintenance every year. What are the contents? This post was last edited by DAC Junlintianxia on 2009-3-2 13:15 ]
Maintenance content: ⒈Internal inspection of static equipment and replacement of scrapped parts ； ⒉Disassembly and inspection of moving equipment and replacement of some parts ； ⒊New technology application transformation and equipment capacity upgrade ； ⒋Replacement of catalysts and chemicals. 5. Adding and replacing lubricating oil for some moving equipment. 6. Inspection of safety valves. This post was last edited by yfq4308 on 2009-3-2 14:21 ]
The 2nd floor said most of it. Some parts that are periodically replaced or potentially damaged also need to be replaced (such as bearings, gaskets, instruments, switches, etc.), although they are not broken. Unblock cleaning equipment. Equipment maintenance (such as refueling and oil change). Most of the content to be overhauled is accumulated in daily life and forms a pattern.
Basically, it mainly involves maintenance, replacement, cleaning, etc., as well as taking the opportunity of maintenance to carry out technical reforms, adding or deleting equipment, pipelines, etc.
Generally, plans should be made in advance to dismantle and inspect mechanical equipment and replace damaged valves. Handling of missing points. Equipment cleaning, etc.
The content depends on the specific conditions of the device, such as: Equipment overhaul, equipment replacement, leakage point treatment, technical transformation project implementation, hidden engineering inspection and repair, valve grinding or replacement, etc.
Then add: Another important task during the shutdown and maintenance of chemical equipment is to use this opportunity to conduct regular inspections of special equipment such as pressure vessels and pressure pipelines, especially the calibration and constant pressure inspection of safety accessories (such as safety valves, etc.) that cannot be verified offline at ordinary times.
There is also the use of this time to carry out reconstruction and expansion of the network. During the maintenance period, workers should use their time to conduct histology * Operation and safety, especially the use of newly added equipment, must also be trained.
Before maintenance, a detailed maintenance plan must be formulated to achieve the purpose of maintenance.
There are also electrical inspections, such as PT100 calibration, etc.
The first thing I want to say is that maintenance does not necessarily need to be done every year. That is very unreasonable. It's very expensive and time-consuming. Under normal circumstances, it is overhauled once every three years. The maintenance contents during shutdown include:: ⒈Internal inspection of static equipment and replacement of scrapped parts ； ⒉Disassembly and inspection of moving equipment and replacement of some parts ； ⒊New technology application transformation and equipment capacity upgrade ； ⒋Replacement of catalysts and chemicals. 5. Major problems that need to be solved urgently in daily production, and 6 minor repair projects that cannot be handled at ordinary times. 7. Inspection of the protective effect of device corrosion, etc.
Agree with the suggestion on the 13th floor!! But does it mean that a new factory that has just been opened for a year can be overhauled in one year?
Large-scale technical modifications can also be carried out if there are people! :handshake
Centrally deal with hidden dangers that cannot be rectified during production.
1. Overhaul of key equipment and critical equipment 2. Cleaning of heat exchangers, easy-to-block and scale-prone equipment 3. Safety valve calibration 4. Technological transformation and technical measures projects, new projects related to the device 5. Repair projects that must be stopped before they can be carried out
