What are the key points of daily maintenance for grain coolers

　　What are the key points of daily maintenance for grain coolers?Let's take a look together.

　　Cleaning and fastening:Clean the condenser and exposed parts of the unit daily to remove dust and dirt;inspect and tighten all bolts to eliminate vibration.

　　Operation status inspection:Check daily to ensure that electrical wiring is secure and well insulated;observe whether there are any abnormal noises during the operation of components such as compressors and fans;check whether the lubricating oil level is normal.

　　Pipeline and filtration maintenance:Clean the filter cartridge on the inlet side of the cooling water and chilled water systems monthly,and check for air inside the pipes.Regularly inspect the cooling tower nozzles and filters for blockages.

　　Refrigeration system monitoring:Observe the state of the refrigerant through the oil sight glass.If foam appears,investigate for leaks or adjust the expansion valve.Regularly check the refrigerant level and replenish as necessary.

　　Startup and shutdown and protection:In case of faults such as high/low voltage protection and overload,it is necessary to investigate the cause and repair before restarting the machine.Unauthorized adjustment of protection settings is strictly prohibited.

　　Long-term shutdown management:Do not cut off the main power supply unless in an emergency.Before long-term shutdown,it is necessary to shut down the unit,drain the water from the system,and carry out moisture-proof treatment.
