1.Working principle of Vacuum deaerator
According to Henry's law,the solubility of gas in water is related to the water temperature and pressure. At a certain temperature,the pressure of the gas is proportional to the pressure.Under the pressure,the water temperature decreases,the solubility of the gas increases,the water temperature increases and the gas solubility decreases.When the water pressure is reduced,the gas can be dissolved in the water,so that the gas in the water can be removed.Vacuum deaerator is through the generation of vacuum,the free gas and dissolved gas released from the water,and then through the automatic exhaust valve system,the water re injection system.These low water volume of water is unsaturated water and is highly absorbent of gas,it will absorb gas system so as to achieve a balance between water and gas.Vacuum deaerator to repeat such a cycle every 20~30 seconds.Most gas of the system will be removed by adopting such circulation.
2.Technical characteristics of vacuum deaerator
1.Can greatly shorten the heating or cooling system for the first time after the initial injection of the exhaust time,is conducive to the initial commissioning of the system.
2.The vacuum deaerator can remove the gas from the system,reduce air resistance significantly and reduce energy consumption to ensure the reliability during the operation of the system.
3.Eliminate the pump cavitation,reduce system operation noise.
4.The time and cycle of the vacuum deaerator can be adjusted according to need.
5.The capacity of single equipment applicable system can reach up to 150 m3 and more than one set can be used in parallel.
6.The vacuum deaerator is equipped with terminal and has the function of remote control.
7.The vacuum deaerator can be used in any heating or cooling system to improve the performance of heat exchanger.
8.Because the type of the equipment is vacuum degassing and deoxidation, there is no secondary pollution problem.
9.The vacuum deaerator can slowly down the oxygen corrosion of pipe network,radiator and water pump significantly and prolong the service life of the system.
10.When the system runs normally,the equipment can exhaust the gas resulted from the leakage of pipe network and the make up water of the system with non-stop to keep stable operation of the system.
11.The vacuum deaerator can eliminate the small bubbles attached to the surface of the heat exchanger to improve the heat changing efficiency.
12.The vacuum deaerator is small in size and saves space.The installation is easy with flexible installation location and it is convenient for maintenance.The equipment runs automatically with safe and reliable performance.
3.Application of vacuum deaerator
1.All closed water circulation system
2.All kinds of heat supply and cooling system water circulation system
3.Central heating system
4.Heating and cooling system of capillary network

6.Installation notes of vacuum deaerator
1.The vacuum deaerator must be installed on the return line of heating supply and cooling system. The point of the installation shall be within the range of working pressure and its water temperature shall not exceed 60ºC.
2.If the vacuum deaerator is installed in the heating supply system,the distance between installation location and highest point of the system shall not less than 15 m.While the vacuum deaerator is installed in the cooling system,the distance between installation location and highest point of the system shall not less than 5 m.
3.Please install the vacuum deaerator in the ventilated and dry position.
4.The equipment shall connect to the power source of 380V/50-60Hz.
5.Please confirm that the equipment shall be equipped with suitable constant pressure and expansion system and the fluctuation within a narrow range of system pressure will be caused by the water when the water comes in and out the vacuum deaerator.
6.The overpressure protection valve must be installed in the system to prevent the system from excessive pressure.
Application:degassing of circulating chilled water and hot-water system of central air-conditioning Client: Wanda Plaza Core advantage:The degasifying effect of vacuum deaerator developed and produced by Peide Water Treatment Equipment Co.,Ltd. has reached up to 99% with automatic operation and the equipment is reliable and stable. Introduction to the vacuum deaerator:The operating pressure of the system is 0.67 Mpa and the water capacity of system is 102 m3.During the initial operation stage,the average operating time is 15 hours/ day in one month.After the first month,the average operating time is 2-3 hours/ day. The sound of water flow is much louder at the beginning.But the sound of water flow will disappear after one month.
