AI Technical Summary

Technical Problem

Traditional membrane degassing devices are inefficient in low-temperature environments and cannot accurately measure gas volume, resulting in large errors in degassing efficiency and measurement results.

Method used

The degassing structure employs constant low pressure and gas volume measurement. By raising the liquid temperature through a heating element to reduce the solubility of dissolved gases, combined with piston drive and air pump circulation, it achieves rapid gas escape and uniform distribution. Furthermore, the conical cavity guides the gas flow, increasing the oil-gas contact area to achieve efficient degassing and accurate measurement.

Benefits of technology

Improving degassing efficiency under constant low pressure conditions, reducing the impact of temperature on efficiency, achieving accurate measurement of gas volume, and enhancing the accuracy and efficiency of gas detection.

Abstract

The utility model provides a kind of degassing structure based on constant low pressure and gas volume measurement, first, the liquid (for example transformer oil) to be degassed enters the degassing cavity inside the degassing chamber. The heating element arranged on the degassing chamber heats the liquid, increases the temperature of the liquid, thereby reduces the solubility of the dissolved gas therein, and promotes the release of the gas in free state. The characteristic gas released is rapidly circulated and uniformly distributed in the gas circuit by the air pump, and the gas circulation generates bubbles in the liquid, which can increase the gas-liquid contact area and further improve the degassing efficiency. The liquid is circulated in the oil circuit by the oil pump, which plays a role in stirring the liquid in the degassing chamber to improve the degassing efficiency. Through the comprehensive synergistic effect of heating, air extraction, bubbling and stirring, the problem of low degassing efficiency of traditional permeation membrane method is solved. The displacement amount of the piston in the cylinder can be used to reflect the gas volume entering the cylinder, and thus direct measurement of the volume of the released gas is realized.
