The degradation of oil is inevitable, regardless of the machine in which it is used. This is because, over a period of time, contaminants will enter the oil, causing damage to internal components, hydraulic seals, O-rings and the like. When lubricant degrades, an entire system and hydraulic pressure can be affected, leading to reduced reliability and performance of equipment.
In an earlier article we discussed oil analysis in terms of outsourcing oil tests, ensuring proper sample areas and frequency. Here we will examine additional elements of proper oil analysis: strategy, equipment and alarms.
When cylinder performance begins to decrease and replacement is not an option, the search begins for ways to improve performance. This article will discuss suggestions for performance improvement as well as sizing and selection considerations.
High oil temperatures have many symptoms: slower machine speeds, sludge and varnish formation, and more leaks due to hardened O-rings. All these factors can do significant damage to hydraulic systems. The bottom line is that if the oil in your system is higher than 140 degrees, you are placing it at serious risk of failure. This article will outline the causes of high oil temperature, as well as some solutions to controlling it.
If you think of a hydraulic system as a human body, and the oil which goes in it as blood, the importance of ensuring the system’s oil is always healthy becomes clear. However, in order to do this, many steps in the right direction must be taken. There are several elements to oil analysis, and when they are put together, they can result in an efficient and successful means of analysing oil.
On the list of the most common causes of hydraulic equipment failure, overheating ranks at number two. Unfortunately, the general understanding about how to identify and address overheating issues is all too often misunderstood.
In hydraulic systems, lubricants can sometimes be mixed. Whether done accidentally or not, there are consequences to mixing lubricants. Even mixing the same kind of lubricants can place a system at risk if those lubricants have different viscosities.
The hydraulic power pack is a vital piece of equipment used to power hydraulic fluid from one location to another when a reliable or stationary source of power is not available.
In your search for hydraulic equipment lubricants, you likely discovered that lubricant suppliers can offer several other products and services. With each supplier offering something different from full service to niche-specific products, matching products and services to the needs and applications of your company can provide a significant challenge.
There are many ways to reduce the contamination that can cause an increase in your system’s copper levels. Although they can be alarming, significant increases in copper do far less damage. Interestingly, it’s when the increase in copper is small and subtle that hydraulic system trouble can follow. Close examination of these increases, as well as checking for simultaneous increases in aluminium, lead, zinc and tin is something which should also be watched closely and taken seriously.
