【Weekly Topic】Discussion on summer equipment maintenance (first week of June)
Thread Content
As temperatures rise and summer approaches, and given the operational characteristics of chemical manufacturing enterprises – many of which operate under high temperatures and pressures and are prone to poisoning incidents – preventing equipment from overheating or overpressuring becomes an issue that must be taken into consideration every summer. This week’s topic: What effective measures have you taken this summer to prevent equipment from overheating? Everyone is welcome to engage in in-depth discussions! 【Call for Essential Knowledge Compilation in the Mechanical Field】http://bbs.hcbbs.com/thread-1389197-1-1.html Seeking weekly topics and daily questions (prizes for participation) http://bbs.hcbbs.com/thread-1373282-1-1.html
1. Establish a special maintenance team for pumps and machinery during the hot season. Inspections were mainly carried out on the air-cooled fans, as well as on the temperature, vibration, leakage, lubrication, and turning of pumps; attention was paid to the proper operation of the cooling water system and the lubricating oil system. 2. Establish a safety inspection team for the peak summer period. The main goal is to prevent production disruptions caused by failures in electrical systems, instruments, pumps, etc., as a result of high temperatures ； Ensure that no safety accidents occur due to electrical systems, instruments, pumps, etc., under conditions of high temperature and high load. 3. Strengthen process management, increase the frequency of inspections, and enhance monitoring as well as the identification of potential hazards. Pay close attention to the operation of heat exchangers, cooling water, etc. 4. Strengthen the management of ventilation and cooling equipment to ensure that the indoor temperatures in areas such as instrument rooms, power distribution rooms, and control rooms are kept within normal ranges. 5. Increase the inspection of safety facilities, such as safety valves, thermometers, and sprinkler systems, to ensure they are in good condition.
There are no specific summer maintenance procedures in northern Shaanxi; primarily, electrical substations and instrument cabinets require continuous cooling； There are very few mechanical parts.
The temperature in Guizhou isn’t very high; the main concerns are lightning protection and flood prevention. For circulating cooling water, it’s sufficient to pay attention to temperature control. :P
What 1L said is very comprehensive. All the doors and windows in the turbine building need to be opened, and the cooling water valves should be set to a higher level. There’s no need to worry about the electrical room, as the air conditioning there maintains a constant temperature throughout the year.
What is mentioned on the first floor refers to overall behaviors, that is, the behaviors of senior management as a whole. However, when it comes to specific equipment, things may differ; for example, it’s not advisable to open the windows in the factory building when using an air compressor, as this can allow more dust to enter. It is also very necessary to conduct an early inspection of the cooling system
In hot weather, it is necessary to ensure that the air conditioning systems in the cabinet rooms are functioning properly； Regular cleaning of the pump’s water jacket ； Regular cleaning of the compressor oil cooler ； Adjust the circulating water flow rate as needed based on the inlet and outlet temperatures of the heat exchanger ； Adjust the blade angle of the air-cooled fan based on temperature.
