Advantages
Strong corrosion adaptation for special oil medium
Full stainless steel body and fluororubber sealing configuration resist strong chemical corrosion of phosphate ester medium. It avoids seal aging and equipment leakage, realizing long term stable operation in power plant DEH hydraulic systems.
Eliminate core failure of servo valve corrosion
Exclusive dry ion exchange and polar adsorption technology removes invisible polar degradation products. It stably improves oil resistivity, fundamentally suppresses micro current electrochemical corrosion and reduces servo valve replacement frequency.
Meet precision hydraulic cleanliness standards
Equipped with 1μm high precision filter elements. The outlet oil cleanliness stably reaches NAS1638 Grade 6, matching the ultra high cleanliness requirements of precision hydraulic components.
Flexible intelligent upgrade capability
Reserved installation interface for online detection and PLC system. It supports automatic monitoring, data recording and early warning, helping users realize unmanned maintenance and standardized oil management.
High efficiency vacuum evaporation structure
Optimized three dimensional vacuum flash structure expands evaporation area. It features high dehydration and degassing efficiency, and adapts to on site oil pumping and oil replenishment demands of various working conditions.
Application
Mainly applied to DEH fire resistant oil purification for thermal power and nuclear power steam turbine control systems. It is also suitable for fire resistant oil regeneration in high temperature and high pressure hydraulic equipment in petrochemical, metallurgical and large industrial fields.
FAQ
Q: Why phosphate ester fire resistant oil causes servo valve corrosion after long term operation?
A: Long term high temperature operation leads to hydrolysis and oxidation of phosphate ester oil, producing polar conductive substances. These impurities reduce oil resistivity, form micro electrochemical loops inside the hydraulic system, and cause precision servo valve spool corrosion and sticking failure.
Q: What is the essential difference between this purifier and ordinary vacuum oil filters?
A: Ordinary equipment only removes water and solid particles. This model targets the core problem of fire resistant oil deterioration. It removes dissolved polar pollutants through ion exchange and adsorption, which is the key to recovering oil resistivity and eliminating corrosion risks.
Q: How to judge whether the adsorbent and resin need replacement?
A: On site judgment is based on two core indicators: continuous failure to raise oil resistivity to standard value and ineffective acid value reduction after circulation purification. Regular testing can avoid system corrosion hidden dangers caused by saturated adsorption materials.
Q: What harm will substandard oil resistivity bring to power plant DEH system?
A: Low resistivity will continuously trigger electrochemical corrosion on precision valve groups. It leads to valve core wear, jitter and action deviation, causing unit load fluctuation and even unplanned shutdown in severe cases.
Q: What are the advantages of optional online detection modules for power plant operation?
A: It realizes real time tracking of oil water content, particle pollution and operating status. It avoids lag errors of manual sampling and laboratory testing, supports early fault warning and regular maintenance scheduling.
Q: What operating precautions ensure long term purification stability?
A: Avoid empty heating and over vacuum operation. Filter elements need regular cleaning according to oil pollution degree. Prevent excessive gelled oil from entering the equipment to avoid blockage of internal adsorption and evaporation structures.
