Transformer Oil Vacuum Filtration Machine

I. Introduction

The.No Chinese content provided. Please provide the text to be translated.Since the birth of the Taiwan full-laying vacuum oil purifier, it has been recognized for its lightweight design (only weighing as much as imported and vertical machines)60%Compact, low-noise, and user-friendly, the product has been widely promoted and applied by various manufacturers, winning international and domestic gold awards multiple times. Popular domestically, it is also exported to Southeast Asia and the United States.DZLThe single-stage unit is designed for transformer processing and vacuum oiling, featuring high efficiency, low noise, lightweight design, ease of use and maintenance, and the absence of the need to replace filter paper and cores. It effectively removes moisture, impurities, and harmful gases like hydrocarbons, enhancing flash points and oil withstand voltage values. It is suitable for drying damp transformers and current transformers, and when connected in parallel with regeneration units, it accelerates acid removal, improves insulation strength, and reduces dielectric losses.

Section II: Principle

Under vacuum, the boiling point of moisture in oil significantly decreases, allowing for the volatilization of a large amount of moisture at lower temperatures. As shown in Figure 1, the higher the vacuum level, the greater the decrease in boiling point, leading to faster evaporation of moisture. Similarly, higher temperatures also accelerate the evaporation process.

III. Performance of Departments

1Coarse Filter: Removes coarse impurities, preventing blockages in the filter's flow pipes and reducing wear on the oil pump.

2High Precision Oil Filter: Achieves a higher degree of oil precision.

3Heater: Placed on the horizontal vacuum vessel, it enhances evaporation efficiency and surface area, significantly reducing...

The weight and dimensions of the oil filter are crucial, especially when placed horizontally, as they can remove a significant amount of moisture even under relatively low vacuum conditions.

4The Anti-Spill Nozzle: Oil spraying is a common issue in standard vacuum oil separators. Our machine's anti-spill nozzle separates oil froth into oil and gas, where the oil returns to the oil pump, and the gas is expelled through the vacuum pump, preventing oil splashes that occur when oil froth enters the vacuum pump.

5Vacuum Pump Oil Filter: During the vacuum pump's suction process, a portion of the steam is released into the atmosphere, while the rest is condensed into water, remaining in the vacuum pump oil. This device separates the water from the oil, allowing for water discharge through the bottom drain valve. Additionally, it serves to remove a significant amount of impurities and lower the temperature of the vacuum pump oil.
