In power, petrochemical, machinery manufacturing and other industrial sectors, the cleanliness of transformer oil, turbine oil, hydraulic oil and lubricating oil directly determines the stability and service life of equipment. During long-term operation, oil will inevitably be mixed with water, air and mechanical impurities, accompanied by oxidation, acidification and turbidity. These problems easily lead to reduced insulation performance, pipeline blockage, component wear and higher energy consumption.
As a professional oil purification device, ZLYC high efficiency vacuum oil purifier integrates vacuum separation and multi-stage precision filtration technology. It realizes deep purification and regeneration of various industrial oils, restores oil performance, cuts equipment maintenance costs, and serves as core equipment for industrial oil maintenance.
1. Working Principle
ZLYC series adopts integrated technology of vacuum flash separation, multi-gradient filtration and condensation recovery, which solves the limitation of single filtration of traditional oil purifiers and thoroughly removes impurities, water and gas step by step.
Based on the difference of saturated vapor pressure between water and oil, free water, emulsified water and dissolved gas in oil are vaporized and separated under negative vacuum environment. The vaporized water vapor is cooled and liquefied by condensation system and discharged separately. After dehydration and degassing, the oil passes through three-stage gradient filters in sequence. Gradient glass fiber filter media intercept particles of different sizes hierarchically, finally outputting clean oil with low water content and no bubbles to complete a full purification cycle.
2. Core Advantages
2.1 Multi-dimensional High-precision Purification
Integrated six major functions: dehydration, degassing, impurity removal, acid reduction, color improvement and insulation enhancement. It can thoroughly break oil emulsification, remove free, emulsified and dissolved water, intercept micron solid particles, adsorb acidic substances generated by oil oxidation, improve oil color and greatly boost the dielectric strength of insulating oil.
2.2 High Efficiency & Energy Saving
Equipped with optimized vacuum system, stable vacuum degree and fast flash dehydration speed. Multiple flow rate models cover different working conditions. Constant temperature heating system prevents oil high-temperature oxidation. Low filter material loss reduces long-term operation cost; running noise is low to fit daily workshop operation.
2.3 Complete Safety Protection & Long Service Life
Full set of safety protection devices including overload, overheating, phase loss and low pressure protection, effectively avoiding risks of oil pump idling, pipeline blockage and abnormal temperature. Front coarse filter blocks large particles to protect oil pump and precision filters, extending service life of core parts. Compact fully sealed structure prevents oil leakage and secondary air mixing, adaptable to wide temperature working environments.
2.4 Easy Operation & Low Maintenance
Integrated movable design with fixed and mobile optional models. One-button intelligent operation requires simple training for operators. Filter replacement and pipeline inspection are easy without special tools, greatly lowering maintenance labor cost.
