How to clean the spiral pre-cooler after use: One: After each time, the spiral pre-cooler is completely rinsed with water, but it cannot be directly washed with a spray pipe. Two: The grease is replaced once every six months in the spiral pre-cooler bearing, and calcium-based grease is used. Three: The chain of the spiral pre-cooler may cause the original lubricating oil to volatilize after long-term operation, which may cause the chain of the spiral pre-cooler to be unbalanced during operation, increase noise, and crawl. Add butter or a thicker lubricant to the chain. Four: The spiral pre-cooler should not be in contact with corrosive materials, so as not to affect the use and shorten the service life of the equipment.
