Hydraulic Filtration

Clean Hydraulic Fluids Are the Key to Top Performance

Clean Hydraulic Fluids Are the Keys to Top Performance - Power Lines - Parker Hydraulic Filtration DivisionFor optimum renewable energy performance, power generation equipment including transmissions, EHC drives, turbines, and transformers depend on clean hydraulic fluids and oil. When a hydraulic system becomes contaminated with air, water, or suspended solids, performance begins to break down. Any of these contaminants can cause a lack of lubrication between component surfaces, which results in increased friction, leading to more wear debris and eventual failure.

Power generation is one of the few industries that replaces hydraulic fluids and oils only when it is absolutely necessary, adding new fluid when reservoirs become low. This makes it even more important that power generation engineers utilize high-quality filtration systems to keep fluids and lubricants as clean and long-lasting as possible.

Protect mission-critical equipment

Clean Hydraulic Fluids are the Key to Top Performance - Sentinel Fluid Purification System, Hydraulic Filtration division, Parker HannifinWater, entrained air, gases, and solid particulates contaminate turbine oil and hydraulic fluid and must be removed on a regular basis. Water is one of the most common contaminants in a fluid system and one of the most damaging. Therefore, it is especially important to protect mission-critical hydraulic and lubrication systems through the use of appropriate filtration.

With conventional purifiers, water cannot be removed until the hydraulic reservoir fluid reaches and maintains a temperature of 150 degrees F. This can take hours, if the ambient temperature is low and the reservoir volume is large, which slows down operations and drives up energy costs. In contrast, Parker’s Sentinel™ fluid purification system removes water and other contaminants from hydraulic fluid more efficiently, and at less cost.

The Sentinel treats contaminated hydraulic fluid in smaller volumes. Every two minutes a 6KW heater heats 4-5-gallon batches of fluid at a time, cleaning the fluid and then releasing it. This conserves power and saves time that would otherwise be spent heating the entire main system reservoir to the required temperature.

 

Other advantages include:

  • Optimized size, weight, and design for oil reservoirs up to 1,000 gallons
  • Up to 75 percent lighter and smaller than most traditional full-scale purifiers on the market
  • Easy to place, position, and move due to smaller overall footprint
  • Can be automated with customer-selected parameters within Parker's IQAN interface

Automatic monitoring

The Sentinel is the only purifier on the market with an automatic monitoring system. A Parker IQAN controller allows the operator to set the parameters of operation. Once the parameters are set and the unit is turned on, it operates until the low limit of water content has been attained. At this point, the timing setting takes over. The timer can be set from 1 hour up to 720 hours. Once the time setting is reached, the unit turns on, pulls a sample of the fluid and measures the water content. If the content is below the high setting, the unit goes back to the timing mode. If the water content is at or above the high setting for water, the unit goes back into operation and runs until it reaches the low setting again and repeats. The Sentinel can also be operated in standard mode—once the parameters are set and the unit starts, it will run until it reaches the low water setting and then turns off. It will not come back on until the operator restarts the unit.

Automatic filtration extends the usable life of fluids, minimizes energy consumption, and reduces costs. By keeping the hydraulic system as dry as possible, the Sentinel lessens the chance of destroying a bearing on a turbine and losing millions in revenue as a result of lost time and mechanical repair.  

Sentinel™  an efficient, portable unit designed for fluid purification and protecting hydraulic systems was awarded the title of "Product of the Year 2015" by the magazine "Inżynieria i Utrzymanie Ruchu” (“Engineering and Maintenance" in Poland) in the category of "Diagnostics, monitoring, and regulation." The Sentinel stretches maintenance budgets and boosts productivity, by streamlining the dehydration process and reducing costly, unscheduled downtime.
