Oil purity & sensors As already mentioned in various articles, oil cleanliness is very important for the service life of the system-relevant components and has a direct impact on the availability of the system/machine. Do you know how your oil is doing? Do you know the machine manufacturer’s requirements and how do you…
Errors during commissioning and repair Employees filling a unit Errors often occur before the system is switched on for the first time, leading to disruptions and failures. When it comes to proportional and servo-hydraulic valve technology, the following rules of thumb help to avoid common pitfalls. Hydraulic systems with proportional or servo-hydraulic valve…
Why is the installed filtration on my machine not sufficient? Why should I also install a bypass filtration! A customer asked us this question and… it’s justified… We cannot give a general answer to this question because the causes of medium contamination are diverse and vary from application to application. Some…
The determination of water, Karl Fischer titration (KFT) The Karl Fischer method is the quantitative determination of water by titration, hence also Karl Fischer titration or simply KFT. The method was developed in 1935 by the German chemist Karl Fischer at Lazăr Edeleanu GmbH and is also used to determine water in oils (source:…
Water in the oil?! In addition to contamination of the oil by particles, water is another trigger for malfunctions and damage to system-relevant components in the oil circuit. Water can occur in oil in different states: dissolved water, free water and emulsions. The dissolved water is initially uncritical and is usually created through…
Why oil care is so important our article at www.fluid.de Importance of oil care in hydraulics: Impure oil significantly shortens the lifespan of machines. At Leiber, a new filter system improved the oil purity class, which is essential for the longevity of the hydraulic components. Causes of Oil Pollution: Assembly, incorrect filling,…
That’s why oil care is important… 70-80% of hydraulic failures are caused by contaminated oil! But what does that mean specifically? Oil is the most important component in hydraulic and lubricating oil systems; nothing works without oil! And with contaminated oil, things don’t work for long; downtimes are sometimes associated with very high costs!…
Extend the service life of your hydraulic components! Defective radial piston and gear pump due to excessive contamination The cleaner the oil, the longer the system-relevant components last! Each hydraulic component has a minimum degree of cleanliness for the operating fluid according to the manufacturer’s specifications or other recommendations, usually according to ISO 4406:1999.…
Oil condition sensor or laboratory analysis? An oil analysis in an oil laboratory is essential in order to correctly assess the condition of the oil and to determine the current state of oil cleanliness and oil quality. Before any changes are made to the hydraulic system or the process on suspicion, the ACTUAL…
Oil change vs. oil maintenance – Hydraulic oil Although domestic sales of hydraulic oil have fallen significantly in recent years, they still amounted to an impressive 80.2 thousand units in 2018. tons (source: MWV Annual Report 2019). According to a study, an average of 75% of hydraulic oils are recycled and…
