後藤 零MiembroSilica gel can lose some moisture through air drying, but it is not an effective method for full regeneration. Air drying is slow and does not reach the temperatures needed to thoroughly remove absorbed moisture. For complete moisture removal, heating the silica gel to 120-150°C is necessary. GlobeCore offers equipment designed to automate this process for larger-scale regeneration, ensuring that the silica gel is properly dried and can be reused efficiently without relying on the slow process of air drying.
後藤 零MiembroSilica gel removes moisture through adsorption, where water molecules are attracted to and held on the gel’s surface. Over time, the silica gel becomes saturated with moisture and loses its effectiveness. Regeneration is required to remove this moisture and restore its drying capacity. By heating the gel to 120-150°C, the absorbed water evaporates. For industrial applications, GlobeCore offers advanced equipment that automates this process, ensuring effective moisture removal and maximizing the lifecycle of the silica gel.

Filtration primarily removes solid contaminants like dirt, metal particles, and sludge using filters, while purification goes beyond filtration by addressing dissolved gases, moisture, and chemical impurities. Purification often involves degassing, dehydration, and sometimes regeneration of the oil through chemical treatments to restore its dielectric properties, making it more comprehensive than filtration alone.
octubre 7, 2024 a las 1:00 pm en respuesta a: How does Hydraulic System Filtration impact the maintenance schedule of hydraulic machinery? #123036後藤 零MiembroHydraulic System Filtration significantly impacts the maintenance schedule of hydraulic machinery by determining the frequency and scope of maintenance activities. Effective filtration ensures that contaminants such as particulates, moisture, and acids are consistently removed from the hydraulic oil, thereby protecting machinery components from wear, corrosion, and damage. This protection reduces the need for frequent repairs and extends the lifespan of hydraulic parts like pumps, valves, and actuators. As a result, maintenance schedules can be optimized, focusing on proactive rather than reactive maintenance. High-efficiency filtration systems allow for longer intervals between oil changes and filter replacements, minimizing downtime and operational disruptions. Additionally, cleaner hydraulic oil improves system performance and reliability, reducing the occurrence of unexpected failures and extending overall equipment life. Consequently, robust hydraulic system filtration contributes to a more efficient and cost-effective maintenance regimen, ensuring sustained performance and reducing overall maintenance costs.
