There are two main consequences of water hazards - it causes wear and tear of machines and it causes rust and corrosion of metals. Equipment requires lubricants, the main function of which is to lubricate and reduce wear, preventing metal wear. In addition, lubricants provide protection against rust and metal corrosion. Water weakens the lubricant's lubrication and anti-wear effect, and also affects the ability to prevent rust and corrosion, whether it is water or moisture in the air (water vapor or high air humidity).
Moisture on the lubricating oil, grease performance mainly affect the following aspects:
Reduce the lubricity of the lubricant:
Lubricating oil has hygroscopicity, some kinds of oils are more serious, such as ester oils, most of the lubricating oils have poor water resistance, so the use of waterproof consciousness and waterproof measures.

Reduce the adhesion of grease:
Lubricating grease has a certain adhesion ability, grease if absorbed water will become soft and thin, lose adhesion, in the water flushing will fall off from the lubrication part, so the water resistance of the grease is an important indicator, there are special testing standards to detect the water resistance of the grease, the test results recorded grease in the role of the percentage of the loss of water, the larger the percentage, the worse the resistance of the grease to water.

Low temperature performance:
After the lubricant absorbs a certain amount of water, the low temperature performance will be affected, mainly because water freezes at 0 degrees. After absorbing water in the grease, it will become hard at low temperature, which affects the low temperature pumpability and lubrication ability of the grease.

How to waterproof?
The best strategy is to prevent the main, sealing is the key, in addition to the use of good performance seals, but also often check the lubricant / grease. Observe whether the grease is thinning and whitening, and whether the lubricant is whitening, emulsifying (looks milky), and decreasing in transparency. Avoid water sources around the equipment, avoid sealing parts when flushing the machine with a water gun, and prevent water from entering the lubrication system.
