What's the best way to maintain the Concrete Batching Plant in winter? With the change of seasons, the special oil for screw compressors should also be replaced, because the oil used for compressors in summer is different from that in winter, and the temperature in some areas is particularly low, so special oil with freezing point lower than local temperature should be replaced. There is a great temperature difference between day and night in winter, which leads to the looseness of screws and bearings of air compressors. Therefore, the user must also check the looseness of the equipment in a planned and step-by-step manner. Water pumps are reasonably waterproof and unfrozen in winter!
