Introduction to oil cleanliness
Fluid is one of the most important components of the hydraulic system. The majority of hydraulic failures are caused by contaminated fluid. This contamination can enter the system in different ways causing various contamination types and system failures. To help you reduce downtime of your hydraulic system we offer you the white paper "Introduction to Oil Cleanliness" for free. Divided in five chapters we discuss contamination, oil analysis, filtration, maintenance...
Clean oil thanks to RMF offline filter
To make sure that the hydraulic fluid in Hawe's HPU remains well conditioned the oil is kept clean through an RMF offline filter OLU2B en KL121R desiccant breather. HAWE manufactures sophisticated hydraulic components and hydraulic controls for the Mobile, Industrial and Renewable Energy market. HAWE Inline Hydraulik GmbH in Berlin is the production facility for the swash plate design piston pumps. Recently a state of the art test centre was build in the facility...
Desiccant breathers prevent condensation
Drillmec was experiencing water problems in their hydraulic system and investigated the cause. Investigation showed that condensation of moist air in the reservoir was the cause of the water contamination. RMF offered a solution with the RMF air conditioner (desiccant breather) product range. After a long testing period RMF air conditioner type KL121R are now fitted to all new build HH series drilling rigs and also available as a retrofit. Drillmec is an international leader in design, manufacture and distribution...
Filtration of water from biodegradable hydraulic oil
Two watercooled hydraulic power units, owned by IHC Hydrohammer, were contaminated with water. The Panolin oil needed to be dried before the start of a new project. The solution for this water problem was a vacuum dehydration unit: the RMF Maxi Water Vac. Water concentration both HPU’s at start: 420 ppm. Water concentration after 7 days of running the unit: 60 ppm for HPU 1 20 ppm for HPU 2....
Micro filtration and monitoring in one
Fugro purchased RMF "smart" offline filters to be mounted to the central hydraulics system of it's newly build survey vessels, the Searcher & Galaxy. The central hydraulic system drives the deck equipment such as A-Frame and winches. On top of the hydraulic tank of the hydraulic power unit a RMF offline filter OLUS was installed, the filter unit acts as a kidney loop continuously pumping a small amount of oil through extreme fine...
Combining micro fitration, monitoring and heating
RMF combined micro filtration, condition monitoring and standby heating in one design in order to maintain the oil quality of 6 Rolls Royce thrusters on a deep water drillship. Before installation (Q4 2015) oil cleanliness result was ISO 18/16/12 and after running the RMF unit for three months it improved to ISO 14/12/7. The customer is positive about the results and equipped the whole fleet with OLUHWS units. In total...
Desiccant breathers to protect hydraulic power packs
The hydraulic powerpacks of Incat’s high speed ship are protected against moisture and solid particles by RMF desiccant breathers KL121R. The vessel contains three hydraulic powerpacks, one forward and two aft. All powerpacks are alarmed for low oil level,high temperature, filter clogged and low pressure. The powerpacks supply hydraulics for capstans, trim tabs, steering gear and stern ramp. The power packs are critical for the proper functioning of the vessel. Incat...
Preventing contamination in flight simulators
The hydraulic systems of flight simulators are equipped with highly silt sensitive servo valves and therefore need to be protected against any type of contamination. To prevent all type of fluid contamination at Qantas Flight Training, each hydraulic system is equipped with RMF offline filter OLU2A and RMF air conditioner KL121R (desiccant breather). For over fifty years, Qantas Flight Training has been supporting pilots as they obtain licence approval to fly...
