Primarily utilizes vacuum separation and pressure filtration technologies to remove moisture, gas, impurities, and emulsions from oil, improving oil cleanliness and performance. It is widely used in industries such as power, metallurgy, chemical, and machinery manufacturing.
Core Features
**High-Efficiency Separation of Moisture and Gas:** Utilizing a vacuum environment to lower the boiling point of water, moisture and dissolved gases in the oil evaporate and are extracted at a lower temperature, achieving deep dehydration and degassing. For example, a thermal power plant in the power industry used this equipment to purify turbine oil, reducing the water content to below 50 ppm after three months of continuous operation.
**Precise Impurity Filtration:** The built-in pressure filter removes submicron-sized particulate impurities from the oil, with a filtration accuracy of up to 30 microns. Some models can achieve NAS 1638 standard level 6, successfully filtering submicron-sized metal particles in hydraulic oil systems, such as in steel rolling mills in the metallurgical industry.
Modular Design and High Processing Efficiency: Utilizing a modular structure, the processing capacity can be adjusted according to different operating conditions. A single unit can process up to 6000L/h, increasing efficiency by 40% compared to traditional methods, and optimizing energy consumption, making it suitable for large-scale industrial production.
Working Principle: The core principle of the vacuum oil filtration machine is a coupled process of "vacuum separation + pressure filtration": The oil is heated to a suitable temperature (usually controlled at around 50℃) to reduce viscosity before entering the vacuum tank. Under vacuum negative pressure, moisture and gases evaporate rapidly and are extracted. Simultaneously, the oil passes through multiple layers of corrugated plates or filter elements to remove solid impurities, ultimately yielding clean oil. Some models use a "hot oil circulation" method to re-inject the purified oil into the equipment (e.g., transformer oil tanks), achieving continuous filtration and improving processing efficiency.
Applications:
Power Industry: Used for purifying transformer oil and turbine oil, extending equipment maintenance cycles, and ensuring stable operation of the power system.
Metallurgical Industry: Used to treat hydraulic oil systems in steel rolling mills, filtering metal particles, improving oil cleanliness, and reducing equipment wear.
Chemical Industry: Solve lubricating oil emulsification problems, restore oil lubrication performance, and reduce production costs.
Machinery Manufacturing: Equip cutting fluid circulation systems to increase recycling rates to over 85%, reducing resource waste.
