It is common practice to install a gas-liquid separator to protect vacuum pumps during operation. When liquid impurities are present in the working environment, they must be separated in advance to prevent damage to internal components. However, in practice, gas-liquid separation does not always proceed smoothly. This is particularly true in high-temperature or medium vacuum conditions, where the difficulty of separation increases significantly.
High temperatures and medium vacuum conditions can alter the state of liquid, causing them to transition from liquid to gas. Once this change occurs, conventional gas-liquid separation equipment may fail to effectively capture these gaseous impurities. This is because typical separators rely on physical methods such as baffle separation, cyclone separation, or gravity sedimentation. When liquids vaporize into gases, the effectiveness of these methods diminishes considerably. Gaseous impurities may flow along with the gas into downstream equipment, and if inhaled by the vacuum pump, they can reduce efficiency or even cause damage
To ensure effective gas-liquid separation and prevent gaseous liquids from entering the vacuum pump, a condensation device must be added to the separator. The condenser lowers the temperature, re-liquefying the vaporized liquids so that the gas-liquid separator can then capture them. In high-temperature and medium vacuum environments, the role of the condenser becomes especially critical, significantly enhancing the stability of the separation process and ensuring smooth operation.
In summary, temperature and vacuum level greatly influence the gas-liquid separation process. To achieve efficient separation under high-temperature or medium-vacuum conditions, the use of a condensation device is essential. This not only maintains separation performance but also protects equipment such as vacuum pumps from damage caused by gaseous liquids. Therefore, in practical applications, it is important to select a gas-liquid separator equipped with a condensation unit tailored to the specific operating conditions.
