Differences between filtration method and electrostatic oil purification method.

Differences between filtration method and electrostatic oil purification method.

Detailed information about the characteristics of the "static electricity oil purification method," which has a working current of only a few mA and poses no danger.

The debris in oil varies greatly in shape and material, and its size ranges from molecular scale to several hundred microns. Moreover, there are many varnish-like semi-solid particles that are liquid at high temperatures but solid at low temperatures, which greatly differ from debris in other liquids. This document provides a detailed explanation of the "electrostatic oil purification method" that resolves contradictions based on the functionality of filters, such as the inability to remove debris smaller than 5 microns, as well as the "filtration mechanism."

[Data] Oil Lifespan

[Data] Oil Lifespan

How long does oil last? The results of the investigation reveal surprising facts!

Just as iron experiences metal fatigue, oil also undergoes fatigue reduction, and it is common practice to replace it before it becomes a significant issue. In this context, a representative from a major company requested an investigation into the specification limits of oil, or its "lifespan." As a result of extensive research and experiments conducted in-house, it has become clear that "as long as contaminants are completely removed, the more oil is used, the better its properties become, and it hardly wears out, exhibiting longevity." In other words, as long as harmful sludge is removed, oil can be used for many years. By properly managing "oil," it is possible to prevent a decline in equipment performance and failures, leading to increased productivity. [Contents] - About the lifespan of oil *For more details, please refer to the PDF document or feel free to contact us.

How to prevent hydraulic equipment failure caused by oxidized sludge?

How to prevent hydraulic equipment failure caused by oxidized sludge?

85% of hydraulic failures are caused by contamination!? As remote production adjustments increase, purification systems help prevent accidents before they occur! *Oil management materials available.

【Preventing Hydraulic Equipment Failures Before They Occur】 ~Keep the purification system running even if the equipment is stopped~ The majority of hydraulic equipment failures are caused by a contaminant in the oil known as "oxidized sludge." Due to the nature of oxidized sludge, when the machine is operating at high temperatures, it becomes fine particles that dissolve in the oil, and when the temperature drops, it tends to stick like glue (gelatinous). This is why machines may not operate after a holiday, necessitating extended warm-up periods. Therefore, it is essential to keep the "purification system" running, especially now when human movement is restricted and downtime for machines is increasing. Additionally, selecting the right purification system is crucial. Since oxidized sludge can become fine particles or gelatinous, standard filters or centrifuges are often insufficient. With electrostatic oil purification equipment, contaminants can be adsorbed regardless of particle size, minimizing the generation of "oxidized sludge" and contributing to the "prolongation of oil life and prevention of equipment aging." CleanTech offers a variety of electrostatic oil purifiers. If you are facing the issues mentioned above or are interested, please feel free to contact us. 【Content Overview】 Oil management amidst restrictions on human movement *For more details, please refer to the PDF document or feel free to contact us.*

Contributing to the SDGs: Numerous applications of wind turbines! Electrostatic oil purifier 'EDC'

Contributing to the SDGs: Numerous applications of wind turbines! Electrostatic oil purifier 'EDC'

The gearbox installed inside the wind turbine experiences severe oil oxidation degradation, leading to damage to the tooth surfaces and bearings.

The gearbox (gearbox) installed in wind turbines uses gear oil, but since it constantly splashes oil, oxidation deterioration is very severe. On the walls of the gearbox, there is a layer of oxidized degradation material more than 1mm thick, and oxidized degradation material also adheres to the gear tooth surfaces. The oxidized substances in the oil have a viscosity similar to glue, causing them to stick to metal wear particles, leading to troubles and damage in various parts. To replace the oil in the gearbox, a truck crane is required, which incurs significant costs. However, performing maintenance can also result in substantial damage. EDC removes oil-related contaminants generated during operation and maintains oil quality stability. It is a unique oil purification device that can reduce the burden on equipment. Clean Tech's EDC (electrostatic oil purifier) is widely adopted in wind power sites in Europe, continuously maintaining the oil in good condition within the generator. This also ties into efforts related to the SDGs, increasing interest in the reuse of oil. For more details about the machine, please check the download below.

Contributing to the SDGs: Did anyone know? Energy-saving effects through oil management!

Contributing to the SDGs: Did anyone know? Energy-saving effects through oil management!

Introduction to oil management, such as "operating oil cleanliness analysis" and "hydraulic motor power consumption change graph"!

How is oil filtration implemented? By cleaning the oil, it can lead to a reduction in power consumption and achieve energy savings. This document introduces "improvement methods" and "examples of improvements." Hydraulic equipment, after several years of operation, can cause issues such as oil leaks, valve sticking, and pump failures. Similarly, due to performance degradation, the power consumption of the motor driving the hydraulic pump, which is the main power source, can increase by 5% to 40%. Did you know this fact? [Contents] ■ Issues ■ Improvement methods ■ Examples of improvements ■ Hydraulic oil cleanliness analysis ■ Graph of hydraulic motor power consumption changes ■ Electrostatic oil cleaning machine "EDC-R25 model" Since the establishment of the Lubrication Research Institute, Clean Tech has exceeded 50,000 analysis cases and has become a group of engineers with accumulated data and knowledge. We are not just a manufacturer that produces and sells oil cleaning machines; we operate as a manufacturer that can make appropriate proposals with reliable technology related to oil cleaning. We will strive to contribute to the reduction of hydraulic equipment troubles through the cleaning of lubricating oil. *For more details, please refer to the PDF document or feel free to contact us.
