The VFD series products are intelligent vacuum oil filters specially developed for insulating oil products. They are used for the purification and filtration of electrical insulating oil products such as transformer oil, insulating oil, switch oil, capacitor oil, and refrigeration oil.
The purpose of the VFD series vacuum oil filtration treatment is to eliminate particles, moisture, gas and other pollutants in the oil, and to reduce the acid value. The key indicators of the oil such as dielectric strength, gas content, acid value, dielectric loss, etc. meet the corresponding specifications and requirements to ensure the safe operation of the user's electrical equipment.
This product is widely used in the purification of oil products in the power supply, power generation, power transmission and transformation, power equipment manufacturing, power engineering, electrical equipment maintenance, power testing, electrical scientific research and other industries.
The oil filter also has functions such as vacuuming, vacuum drying, online oil filtering, oil injection, and hot oil circulation, which can fully meet the various use requirements of users on site.
The VFD vacuum oil filter is an independent oil purification and filtration system with a skid-mounted structure. It can be energized online circulation filtration, or it can be moved to the oil filtration point for offline oil filtration.
In addition to reliable oil filtering and purification functions, the equipment can also conveniently switch valves for separate oil extraction, oil injection, oil replenishment, and other functions to meet various user requirements on site.
Features
High dewatering and degassing efficiency: Adopting a three-dimensional evaporation degassing and dehydration system, plus special vacuum fillers, to increase the surface area of the oil film and quickly separate the water and gas in the oil.
Strong impurity removal ability: high β value precision filter material, multi-stage filtration, and step-by-step encryption, to remove fine particles in the oil. The filter element has a large volume, large dirt holding capacity, and long service life, and is equipped with an automatic detection function for the contamination of the filter element.
Short oil processing time: high vacuum and high pumping speed can quickly and efficiently remove water vapor in the oil. After one filtration, the dryness and breakdown voltage of the oil are greatly improved, shortening the oil processing period, and thereby improving the performance of the oil.
Automatic control: This machine adopts high-end configurations such as automatic constant temperature control, automatic liquid level control, and automatic pressure protection to ensure that the equipment does not spray oil during operation and operates safely and stably.
Interlock protection: Overload protection, overpressure alarm shutdown protection, oil shortage protection, oil injection protection, phase sequence protection, etc. ensure the long-term reliable operation of the whole machine.
Humanized indication: Automated design, with oil temperature, pressure, vacuum and other indications, the markings are concise and clear.
Modern design: The oil purification process design of this machine is advanced, it can be processed online or offline, with a high degree of automation, and can realize unattended operation. The equipment has a compact structure and is flexible and convenient to move.
Good comprehensive performance: This machine has the advantages of low noise, easy operation, long maintenance interval, low energy consumption, low operating cost, and high oil filtration efficiency.
Advantages
Double-stage vacuum with large pumping speed and advanced dehydration and degassing system adopts large-area three-dimensional flash evaporation technology, which can quickly and efficiently remove moisture, impurities, hydrocarbons, and other harmful components in the oil, and improve the flash point and Dielectric strength.
It can meet the needs of vacuuming and vacuum oiling the transformer body at the installation or maintenance site.
A sophisticated filtration system, high-quality filter element, and multi-stage filtration step-by-step encryption can effectively remove mechanical impurities in the oil.
Advanced automatic constant temperature control system, automatic liquid level control system, automatic defoaming control system, automatic pressure protection system, and sophisticated configuration ensure high-performance operation of the equipment.
Highly automatic, can be unattended, and the operating status is displayed by the indicator light.
The machine has humanized design, low noise, simple operation, long maintenance interval, low energy consumption, and low operating cost.
The whole machine is equipped with interlocking safety protection, and the oil discharge system, vacuum system, and heating system are interlocked to avoid adverse effects caused by misoperation.
Equipped with leakage and overload shutdown devices to protect the motor.
