Statistics show that a high percentage of plants have neglected to address toxicity levels and safety concerns surrounding the lubricant formulations they use.
Density is an important property in all fluids, including hydraulic lubricants. Density is defined as the measurement of a substance’s mass by relating it to a known volume. Usually, water is denser than lubricants, which is evidenced in hydraulic systems with moisture problems when water is observed settling at the sump’s bottom and then being drained before the system lubricant.
Although the viscosity of a base oil is its most important property, it’s also important to be aware of the roles that lubricant additives play. These compounds, whether organic or inorganic exist either as dissolved or suspended solids within the oil. Depending on the equipment, additives can represent between 0.1 to as much as 30% of an oil’s volume.
Our last blog post detailed the process which should occur to pare down the number, amount, and type of lubricants being used in a location. This post will detail the next step in the process, which is the creation of a lubrication specification document.
When selecting any lubricant for a hydraulic system, three elements must be in place. The lubricant you choose should not only be of sufficient quality, but also the correct lubrication for your application, as well as being as affordable as possible.
