Vacuum degassing machine

Exhaust function:

After the system water enters the vacuum tank under negative pressure, the gas and water are separated. The separated gas is discharged through the exhaust valve, and the discharged water is injected into the system by the pump, repeating the cycle. This effectively solves the air problem in the piping system.

Exhaust principle:

When the vacuum exhaust equipment is running, the pump runs to replenish the water inside the vacuum tank back into the system, simultaneously evacuating the vacuum, and the water in the system is discharged back into the vacuum tank. Due to the large pressure changes, the system water separates gas and water in a vacuum. As the water continuously releases pressure into the vacuum, the separated gas is compressed and expelled through the exhaust valve.

Device features

According to Henry's Law, the solubility of a gas in water depends on temperature and pressure. When the temperature is constant, the higher the pressure, the greater the solubility of the gas in water; in a relative vacuum environment, the gas is almost insoluble in water.

The automatic vacuum exhaust device uses this principle to artificially create a vacuum environment (inside a vacuum tank), introducing water from the system into the vacuum tank for intense gas-water separation. The almost gas-free water is then replenished back into the system. This unsaturated water has a strong adsorption capacity for gases, absorbing bubbles and gas blockages in the system, and then carrying this gas back to the automatic vacuum exhaust device for centralized discharge. The water in the system will exist in an unsaturated form (with almost zero gas content), and even if the temperature rises, the water will not release gases again. This achieves centralized exhaust, and the parallel connection with the system prevents pressure fluctuations in the system.
