As safety requirements for the operation of power equipment continue to rise, two-stage vacuum oil purifiers-as core equipment for ensuring the performance of insulating oil-are becoming indispensable technical assets in global industries such as power, metallurgy, and petrochemicals. Leveraging over 20 years of technical expertise and innovative R&D, Wuhan Goldhome Hipot Electric Co., Ltd. has demonstrated the exceptional application value of its ZYD series high-efficiency dual-stage vacuum oil purifiers across multiple critical sectors. This article provides a comprehensive analysis of the core application areas for Goldhome's dual-stage vacuum oil purifiers.
Power Industry
The power industry is the core application area for Goldhome's two-stage vacuum oil purifiers. The products are widely used for the treatment of insulating oil in oil-immersed equipment such as 110kV to 500kV ultra-high-voltage transformers, reactors, current transformers, and circuit breakers. During the vacuum oil filling process at new substations, Goldhome equipment ensures that new oil meets insulation standards; during equipment maintenance, it enables deep purification of in-service oil; and in routine maintenance, it extends the service life of the oil through online circulation filtration.
Goldhome's two-stage vacuum oil purifier employs oil-water separation technology that combines thin-film evaporation with drying. Coupled with flow-matched two-stage vacuum pumping speeds, it can reduce moisture content in the oil to ≤3 ppm, gas content to ≤0.05%, and increase breakdown voltage to ≥75 kV-with all indicators far exceeding national standards. This deep purification capability directly contributes to the safe and stable operation of the main power grid.
Transformer Manufacturing and Operation & Maintenance Sectors
In transformer manufacturing plants and specialized O&M organizations, Goldhome equipment serves a dual purpose: purifying new oil and regenerating used oil. Newly purchased transformer oil often contains trace amounts of moisture and impurities and must be filtered to meet standards before being injected into equipment. For degraded oil from long-term operation, Goldhome equipment restores the oil's insulation and heat dissipation properties by removing emulsified water and particulate impurities, significantly extending the oil's service life and reducing operational costs.
The YD-100 vacuum oil purifier achieves a processing flow rate of 100 liters per minute, with a vacuum level as low as 60 Pa and two-stage filtration precision down to 1 micron, ensuring compliance with the NAS 1638 Class 4 cleanliness standard. It is particularly suitable for the maintenance of large transformers rated at 110 kW or higher.
Metallurgy and Petrochemical Industries
In the metallurgy and petrochemical industries, a large number of heavy-duty equipment, such as large steel rolling mills and electric arc furnaces, rely on hydraulic and lubrication systems for normal operation. Goldhome's two-stage vacuum oil purifiers effectively remove moisture and impurities from hydraulic oil and turbine oil, preventing equipment failures and downtime caused by oil contamination. The equipment features explosion-proof design and corrosion-resistant materials, meeting the specific operational requirements of chemical plants and refineries while maintaining reliable performance in harsh industrial environments.
Transportation and Special Operating Conditions
Railway transportation systems and marine platforms are another key application area for Goldhome equipment. Transformer oil in railway substations requires regular maintenance, while lubricating oil for shipboard power station transformers and large electric motors faces the challenge of high humidity in marine environments. Goldhome oil purifiers are compact, highly efficient, and easily portable, making them particularly suitable for on-site live-line operations.
To meet the special requirements of high-altitude regions, Goldhome equipment achieves a maximum vacuum of ≤5 Pa, an operating vacuum of ≤35 Pa, and a pumping speed of ≥330 L/s, satisfying the stringent demands of large-scale power transmission and transformation equipment in high-altitude environments. The equipment can perform live-line oil purification for over 300 consecutive hours, significantly improving operational and maintenance efficiency.
