How lubricants are affected by temperature.

It’s common knowledge that lubricants are affected by temperature – in extreme cases negatively influencing performance.

It’s obvious that lubricants are affected by temperature – that’s why multigrade engine oils have a winter rating and an operating temperature rating. But what in the oil chemistry changes with a change in temperature.

Lubricants are affected by temperature changes in several ways.

Use synthetic lubricants to cut costs.

How do synthetic lubricants cut costs in a factory?

We’re often asked the question “How do synthetic lubricants cut costs” – especially when their initial cost is higher!

When estimating the life-cycle costs of machinery, you must take into account several factors. Of course, there is the initial purchase and installation of the equipment, as well as any aftermarket accessories attached to the machine. There is also the cost of ownership, including all the maintenance procedures that are performed routinely to ensure the pump, motor, conveyor, fan, gearbox, etc. is running correctly. Then there’s

What is a phosphate ester fire resistant fluid?

Phosphate ester fire resistant fluid has excellent anti-wear and fire resistance properties.

Phosphate ester fire resistant fluid is primarily used as a fire-resistant basestock in applications such as hydraulic systems, turbines and compressors.

Phosphate esters were formerly a common derivative of coal tar and as a result consisted of a mixture of isomeric aryl phosphates, including the neurotoxic orthotolyl phosphate.

However this production method has declined along with the commercial use of coal tar. Today, phosphate esters are commonly derived from the reaction of phosphorus oxychloride

What Does Water In Gearbox Oil Do To The Lubricant?

Just 1% water in gearbox oil can reduce bearing life by up to 90%.

With water in gearbox oil, the effectiveness of a gear lubricant is compromised when the oil and water do not separate and the oil becomes diluted.

Its destructive effects on bearings can be worse than that of particle contamination, depending on conditions. As with dirt ingress, vigilant control must be exercised over water in gearbox oil to minimize its accumulation in the lubricants and its damage to bearing surfaces.

Experts agree that using a gear oil that quickly separates from water is the most effective way of

What are the causes of engine sludge build up?

There are several causes of engine sludge build up.

Although some of the causes of engine sludge build up, also known as black sludge, may be debatable the consequences are not: If left unattended, oil starvation will lead to catastrophic engine failure. But it’s not only a failure that drivers should be concerned about; while the engine sludge is building up the engine is loosing lubrication and therefore wear increases.

What are the common causes of engine sludge build up?

Engine sludge build up can usually be traced
