Winter bag breaker machine maintenance: special plan for antifreeze and lubrication

The maintenance of bag breaker machines in winter requires special attention to anti freezing and lubrication schemes to ensure the normal operation and service life of the equipment in low-temperature environments. Based on the information I have searched, please provide a detailed explanation of the anti freezing and lubrication maintenance measures for the winter bag breaker machine

1. Antifreezing and lubrication optimization of lubrication system

-In low temperature environments during winter, lubricating grease with excellent low-temperature performance should be replaced, such as low-temperature lithium based grease (suitable for temperature range of -30 ℃ to 120 ℃) or synthetic hydrocarbon lubricating grease (such as Mobil SHC series), to ensure the normal operation of the lubrication system under cold conditions.

-Reduce the oil injection amount by 20% and adjust the lubrication frequency according to the operating status of the equipment, such as checking the lubrication status every 3 months and timely supplementing or replacing hardened grease if necessary.

-For hydraulic systems, it is recommended to regularly check the viscosity of hydraulic oil and replace it with hydraulic oil suitable for low-temperature environments. At the same time, clean the oil-water separator and diesel tank to ensure smooth oil flow.

2. Anti freezing and crack prevention measures for metal components

-Low temperatures in winter may cause metal parts to loosen due to shrinkage, so it is necessary to regularly check the tightening of bolts and apply anti seize agents (such as Loctite 557) to prevent rusting.

-Regularly calibrate the equipment using a laser level to ensure its operational accuracy is not affected by low temperatures.

-For valves and pipelines that are prone to freezing, steam heating can be used to gradually thaw them to avoid equipment damage caused by sudden temperature rise.

3. Plastic protection and load control

-In environments below -15 ℃, the load on plastic components should be reduced to 70% of the rated value to avoid brittle fracture caused by low temperatures.

-For equipment with plastic casings, it is recommended to use epoxy resin to temporarily repair cracks and replace damaged parts if necessary.

4. Environmental humidity and icing management

-Lay moisture-proof mats or heating blankets around the equipment to reduce the impact of condensed water on the equipment.

-Regularly clean the equipment surface of snow and ice debris, and use compressed air to blow them clean.

-If the device freezes, a hot air gun can be used to heat the local area (temperature controlled within 60 ℃), and avoid directly thawing with hot water.

5. Daily inspection and emergency response

-Before starting the device every day, it needs to be manually rotated 3-5 times to confirm that there is no jamming before putting it back into operation.

-If leakage is found on the sealing surface, it should be promptly sealed and the equipment should be stopped if necessary.

-For deactivated equipment, the internal medium should be emptied and insulation measures should be taken to prevent freezing.

6. Long term protection upgrade suggestions

-For outdoor equipment, insulation curtains can be added or the heating system can be partially modified.

-Use silicone sealing rings and stainless steel rollers to improve cold resistance.

-In terms of coating materials, it is recommended to use polytetrafluoroethylene (PTFE) coating or anti sticking coating to enhance frost resistance.

7. Other precautions

-During winter construction, all mechanical equipment should undergo comprehensive maintenance and upkeep to ensure that the lubricating oil meets local antifreeze requirements.

-Under extreme low temperature conditions, it is advisable to avoid applying impact loads to equipment and regularly inspect batteries and electrical circuits.

The maintenance of the bag breaker machine in winter should focus on optimizing the lubrication system, antifreeze treatment of metal parts, protection of plastic parts, and environmental humidity management. Through a scientifically reasonable maintenance plan, the service life of equipment can be effectively extended and its normal operation can be guaranteed.
