Actuator seals and cylinder wear particles contaminate hydraulic oil. Clean hydraulic oil ensures the durable operation of extrusion presses and other hydraulic machinery for extended time periods.

As long as the hydraulic oil remains clean, the operation can run according to the plan. Yet, when particles and water contaminate the hydraulic fluid, its properties deteriorate fast. This contamination causes costly production downtime due to the failure of pumps and other equipment.

Modern hydraulic systems require the use of high-grade, clean hydraulic oil to maximize equipment utilization. A disc-stack centrifuge assures this level of cleanliness with 8,000 g-forces.

The image above shows small hydraulic oil centrifuge systems with built on pre-heaters. This system is ideal for servicing individual hydraulic fluid sumps in the aluminum extrusion or steel scrapping industry.

Operation

A hydraulic oil centrifuge separates water and fine solids from hydraulic oil on a continuous basis. The centrifuge bowl rotates at 7,800 RPM generating 7,000 Gs of force. This centrifugal force is enough to separate particles down to 0.5-micron level as well as all free water.

Applications

Hydraulic oil centrifuges are applicable in all industries that use hydraulic oil for different applications. Some of the common application examples are the Extrusion Industry for Plastic or Metal Extrusion Presses, Stamping Industry for Stamping Presses, Forging Industry for Forging Presses, Molding Industry, Rigging Industry for Cranes and Actuators, Scrapping Industry for Balers and Compactors, etc.

Benefits

Disc stack centrifuges offer several advantages over filters for the purification of hydraulic oil. Some of the main benefits are listed below.

Simultaneous Water And Solid Removal

Three-phase centrifuges are designed to separate water and solid contaminants from the oil simultaneously. The three phases refer to oil, water & solids. Filters do not remove water and require additional separating devices for water removal.

No Performance Degradation

A disc stack centrifuge is a flow-through type centrifuge meaning that the contaminated oil passes through the centrifuge and comes out clean. Unlike filters, the separated particles or solids do not obstruct the flow of the oil and degrade performance.

Wide Range of Particle Removal

Conventional filters have a set particle separation rating based on the perforation size of the media. A disc centrifuge separates particles and water using the centrifugal force generated by the bowl rotation. Therefore, centrifuges can separate a wide range of particles from 0.5-micron level to 250+ microns.

Low Operating Cost

The use of filters requires the ongoing replacement of filter media. This media change is labor and cost-intensive. On the other hand, a disc stack centrifuge does not use separation media that require replacement. Therefore, centrifuges have a big advantage on filters from the operating cost perspective.
