Advanced Multi-Stage Filtration SystemThis oil purifier features a three-stage filtration process: primary, fine, and ultra-fine, employing stainless steel or cellulose composite filters to efficiently remove particles as small as 1 micron. The systems high vacuum degree (up to -0.099 MPa) and ultimate vacuum ( 5 Pa) ensure effective extraction of moisture and dissolved gases, resulting in clean, dielectric-strong oil suitable for high-performance transformers.
Efficient and Safe OperationDesigned for both automatic and manual operation with a digital control panel and PLC options, the ZYD Series allows accurate monitoring and adjustment of settings. Built-in safety features, including a sampling valve, make oil analysis straightforward and regulated, while the quiet (<70 dB), electric-heated operation meets industrial standards for reliability and worker comfort.
Portability and VersatilityFeaturing a trolley-mounted, compact build, the ZYD Series is easy to transport and position on-site. Its design supports a range of flow rates (1,500 LPH for the highlighted version) and adjustable temperature control (ambient to 80C), making it suitable for diverse transformer maintenance tasks across different industries and transformer sizes.
FAQs of Transformer oil filtration machine(vacuum oil purifier):
Q: How does the transformer oil filtration machine remove water and gas from the oil?
A: The machine employs a high vacuum system, using both high vacuum and roots pumps, to create a low-pressure environment. This setup enables efficient extraction of moisture and dissolved gases from transformer oil by promoting evaporation at lower temperatures, reducing water content to 5 ppm and gas content to 0.1% after treatment.
Q: What is the process sequence during oil purification in the ZYD Series unit?
A: Incoming oil first passes through primary, fine, and ultra-fine filters to remove particles down to 1 micron. Simultaneously, the oil is heated (using an integrated electric heater) and exposed to a deep vacuum, which draws out water and gases. The processed oil is monitored for dielectric strength and collected for transformer use, ensuring superior purity and electrical performance.
Q: When should transformer oil be filtered using this device?
A: Transformer oil should be filtered whenever routine testing reveals elevated moisture, gas, or particulate levels, or during maintenance prior to energizing a transformer. Regular filtration ensures optimal insulation properties, prolongs transformer lifespan, and prevents costly breakdowns due to degraded oil.
Q: Where can this oil filtration machine be deployed?
A: The ZYD Series units compact, trolley-mounted design makes it suitable for transformer yards, substations, power plants, and industrial sites. Its mobility allows easy movement between transformers for on-site oil purification, supporting field and workshop maintenance applications.
Q: What are the key benefits of using the ZYD Series oil purifier?
A: Benefits include restoration of oil dielectric strength to 70 kV, precise removal of moisture, gas, and particulates, extended transformer operating life, reduction in maintenance costs, and compliance with IS 6034 / IEC 60422:2013 standards. The automatic controls and high filtration efficiency (>99%) improve safety, reliability, and ease of use.
Q: How is the operating temperature managed during filtration?
A: The machine is equipped with an electric heater integrated in the oil circuit, allowing temperature adjustment from ambient up to 80C. Digital monitoring ensures precise temperature control suited to different oil conditions, guaranteeing optimal filtration results.
Q: What type of oil samples can be collected, and how is sampling performed?
A: A dedicated sampling valve is provided for easy extraction of treated oil samples. This facilitates routine quality checks, verifying that the water content, gas content, and dielectric strength meet specification after filtration.
