Analysis of core technical characteristics
Efficient two-stage vacuum system: high ultimate vacuum degree can reach a
lower ultimate vacuum value (usually in the range of 5-10 Pa, depending on the
model), which is much better than a single-stage vacuum oil purifier.
High dewatering and degassing efficiency: Under high vacuum, the boiling point
of water in oil is greatly reduced, and the solubility of gas is drastically
reduced. The first stage vacuum performs preliminary and rapid evaporation
separation; The second stage vacuum achieves the resolution and removal of deep
residual water and gas at lower pressures. The oil is sprayed in a
"mist" or "waterfall" shape through a specially designed
diffuser or tray.
Fast processing speed: Under the same conditions, the treatment efficiency is
significantly higher than that of single-stage
Vacuum
Oil Purifier, especially for deteriorated oil with high water and
gas content.
Deep purification: It can remove trace amounts of water and gases dissolved in
the oil more quickly and effectively (including corrosive gases, acetylene
gases or some hydrocarbon gases), reduce the moisture content of the oil to the
international level (up to ≤ 5 ppm or even lower), and the gas content ≤0.1%),
significantly improving the dielectric strength and dielectric properties of
the oil.
Core principle: A two-stage vacuum separation structure (usually a
high-efficiency combination of roots pump + rotary vane vacuum pump) is used to
construct a gradient vacuum environment, so that water and gas can obtain
sufficient space and time for efficient evaporation and analysis, and achieve
fast and effective separation.
The multi-stage precision filtration system intercepts and removes all kinds of
solid particle contaminants (metal shavings, dust, fibers, carbides, etc.) in
the oil step by step, and the filtration accuracy can reach NAS 1638 level 4,
significantly improving the cleanliness of the oil.
Optimized Heating and Temperature Control System: Multiple sets of
high-efficiency heaters are used with optimized oil circuit design to ensure
that the oil is heated evenly and avoid local overheating leading to oil
cracking. Equipped with high-precision temperature sensors and PLC control
systems, real-time monitoring of heating temperature and energy efficiency
control (usually set in the safe and efficient range of 0-80°C). Integrated
multiple temperature protections (such as over-temperature alarm, automatic
power off) ensure safe and reliable heating processes.
With its proprietary double stages high vacuum, optimized membrane degassing
technology, precise filtration system and intelligent control and protection.
DVTP Vacuum Transformer Oil Purifier provides an efficient, deep and reliable
purification solution for transformer oil. It can not only quickly restore the
key performance indicators of deteriorated oil, but also serve as a powerful
tool for preventive maintenance to ensure the safe, stable and long-term
operation of power transformers, and is an important and key oil treatment
equipment in the modern power system. By choosing our vacuum oil purifier, you
are choosing a high standard of care for the transformer's core insulation
media.
