Product overview
Heating and cooling system, if there is gas, the system is easy to produce air resistance, resulting in local or systemic circulation is poor, resulting in heating system is not hot, the refrigeration system is not cold. At the same time, because of the oxygen in the water, the heating (cooling) equipment, the pipeline and the steel radiator have oxygen corrosion, which can cause the water leakage and leakage. The gas in the system can also cause the corrosion of the pump, which directly affects the safety of the whole system. The vacuum degassing machine adopts vacuum degassing method to remove the free gas and dissolved gas in the system.
Two, working principle
According to Henry's law, the solubility of gases in water is related to water temperature and pressure. At a certain temperature, it is proportional to the pressure of the gas. Under certain pressure, the water temperature decreases, the solubility of the gas increases, the water temperature increases, the gas solubility decreases. When the pressure of the water surface is reduced, the gas dissolved in water can be precipitated at a lower temperature, thereby removing the gas in the water. Vacuum degassing machine is through the production of vacuum, the water free gas and dissolved gas release, and then through the automatic exhaust valve exhaust system, after the re injection of water into the system. These low gas content in water is not saturated water, with a high degree of absorption of the gas, it will absorb the gas in the system so as to achieve the balance of water and gas. This cycle is repeated every 20~30 seconds for the vacuum deaerator. In this way, the system of all gas removal. Three, product characteristics 1, can greatly shorten the heating or cooling system after the initial water injection exhaust time, is conducive to the initial commissioning of the system.
2, remove the gas in the system, to prevent air resistance, to ensure the normal operation of the system stable and reliable.
3, eliminate pump cavitation, reduce system noise. 4, due to the removal of oxygen in the water, will reduce the oxygen corrosion of the system to extend the use of equipment.
5, due to the removal of water gas, heat exchanger surface will not be accompanied by gas bubbles, improve the heating efficiency.
6, the working time and cycle can be adjusted according to needs. 7, a single application system capacity up to 150m can be used in parallel multiple fand.
8, easy installation, automatic operation, safe and reliable, easy maintenance.
