In the field of industrial power equipment, oil purification treatment is an important link in ensuring the stable operation of key equipment such as transformers and hydraulic systems. In recent years, with the increasing requirements for oil cleanliness across various industries, the oil purifier product line has been continuously enriched, forming diversified solutions covering different scenarios.
From the perspective of structural form, the plate-and-frame pressure oil purifier, as a classic model, uses filter paper as the filtration medium and achieves the interception of impurities in the oil through pressure drive. The matching plate-and-frame oil purifier filter paper has a density and thickness that directly affect filtration accuracy and flow capacity, and users need to reasonably select the model according to oil viscosity and pollution degree. This type of equipment has an intuitive structure and is easy to maintain, making it suitable for occasions with relatively broad requirements for oil precision.
Vacuum oil filtration technology has developed in response to the need to remove dissolved moisture and gas. A single-stage vacuum oil purifier can effectively remove free water and part of the dissolved water in oil, while a two-stage high-efficiency vacuum oil purifier, through a two-stage vacuum separation system, improves dehydration efficiency while also taking into account the retention of light hydrocarbon components. Taking the transformer oil vacuum oil purifier as an example, its design focus lies in matching high vacuum degree with a large evaporation area to meet the strict requirements of the power industry for indicators such as dielectric loss and breakdown voltage of insulating oil. Small-specification models such as the 30L vacuum oil purifier provide flexible options for laboratories or small equipment.
In terms of application form, mobile oil purifiers such as TY-100 integrate the oil filtration system into a movable vehicle body, facilitating on-site oil treatment in substations, workshops, and other locations, and reducing the links involved in oil transfer. Explosion-proof vacuum oil purifiers, meanwhile, are aimed at environments with explosive gases such as petrochemical and coal mining sites, and adopt corresponding protective measures in electrical control and motor selection to meet the safety specifications of special locations.
The vacuum plate-and-frame plate-type oil purifier combines the characteristics of vacuum degassing and plate-and-frame filtration and can handle oil containing more mechanical impurities. Overall, the technical route of oil filtration equipment has developed from single filtration to combined processes, and users can choose suitable models according to oil type, pollutant components, and processing capacity. Equipment manufacturers are also continuously optimizing structural design and control methods to improve operating economy and operational convenience.
