First of all, "24V DC Cooling Fan" plus liquid oil is wrong. By bearing type decomposition of the second page, we know the use of sliding friction sleeve bearings, where oil will extend the use of time and with the volatile, noise will gradually increase. Add the appropriate grease to the bearing, not only can solve the noise problem arising therefrom, and will greatly extend bearing life. To the right fuel, you must first understand the oil. "24V DC Cooling Fan" oil, commonly known as "oil", "light oil", including mineral and synthetic oils. Sewing machine oil, watches oil belong to oil, transformer oil, vegetable oil is not such a case, commonly known as "butter", "dry oil", essentially lubricants + thickener + (additive) mixture of oil from lubrication or lubricant. "24V DC Cooling Fan" thickener in two ways: First, base metals, such as lithium, calcium-based; there are complex thickener, such as lithium complex, urea group, and its role is to grease "hold" in the bearing.
