What is the difference in lubricant selection between normal temperature chains and high-temperature chains?
June 21, 2023
What are the requirements for selecting lubricants for normal temperature chains? Basically, the lubricant used for the chain must meet the following two requirements: 1. Basic requirements: capable of handling slow oscillation motion/high frequency pressure and oscillation loads; The wear caused by mixed friction and boundary friction. 2. Under the premise of sufficient budget, it is required that the lubricant has good permeability, adhesion, and wear resistance. Why should we meet the above two requirements? That's because: the anti wear effect is good, which can maximize the service life of the chain.
Good permeability and adhesion allow the oil to reach the friction area within the chain link, providing a continuous lubrication supply for the chain. The frequency of oiling will decrease; The dosage naturally decreases. How to choose lubricants for high-temperature chains? The working conditions of high-temperature chains are more severe than those of normal temperature chains, so the selection of lubricants requires higher requirements. In addition to meeting the requirements of normal temperature chain oil, high-temperature chain lubricating grease must also meet the following four points: 1. [Good Permeability] Chain oil with good permeability can ensure that each joint of the chain is lubricated. 2. The performance of low volatility and low fuel consumption is better; The usage cost is only low 3. Low residual carbon rate is necessary for the chain to have a long service life 4. [Good pumpability] Many factories use automatic oiling to refuel the chain; The fluidity of the oil is good; Adding oil is more convenient. 5. [Good adhesion] Can it reduce the consumption of chain oil and provide long-lasting lubrication for the chain.
