Using the wrong hydraulic oil in your system is one of the more common hydraulic equipment mistakes.
In short, the better maintained your hydraulic equipment is, the longer your hydraulic fluid is going to last. Most hydraulic contamination can be removed through off-line filtering, and a system that is carefully maintained will not have major issues with overheating and accelerated degradation. If you maintain your hydraulic system well, you will discover that the hydraulic fluid lasts much longer and may only need to be replaced when the additives have been depleted.
The only accurate way to determine when hydraulic fluid needs to be changed is to perform an analysis on fluid samples, preferably from different points in the system. In fact, heat, water, and contamination are the three key factors in shortening the life of your hydraulic fluid. Natural degradation of the hydraulic fluid over time.Operating temperature (high temperatures cause oil to degrade faster).Most recommendations are based on service hours, but there are many other variables that can affect when your hydraulic fluid needs to be changed, such as: Many hydraulic systems come with manufacturer recommendations as to how often the hydraulic oil should be changed, and these recommendations are meant to serve more as guideline than a hard and fast rule. Hydraulic fluid is expensive, and changing it before it actually needs to be changed wastes money, results in more system downtime than is necessary, and can even increase the risk of hydraulic contamination – none of which are good for the system or for your bottom line. Whether it is changing hydraulic filters too often or using the wrong type of hydraulic fluid, these errors can lead to serious problems such as unnecessary maintenance costs, increased repair costs, system downtime, premature wear of components, and even catastrophic failure. When it comes to the repair and maintenance of hydraulic systems, there are certain hydraulic equipment mistakes that occur more often than others.
