Constant pressure water supply vacuum degassing unit
Product overview
Constant pressure water supply vacuum degassing unit is a new type of equipment, which is developed by the international advanced technology to realize central heating and central air conditioning system with constant pressure, expansion, water supply and vacuum degassing four. The equipment is a voltage regulator, automatic water supply and drainage system in automatic expansion, removal system free gas and dissolved gas. The system is always in high efficiency, environmental protection, energy saving movement.
Two, working principle
The constant pressure water supply device can automatically adjust the change of the water quantity of the user by using the adjustable capacity of the pressure tank, and when the water consumption is reduced or no water is used, the water pump can not be started for a long time, so as to achieve the purpose of energy saving. Compared with the water tower, water tank can save investment of about 40%-60%. Compared with the traditional water supply device, the utility model has the advantages of compact structure, less land occupation and less land resource. The device is fully automatic operation, without the need for special management, reliable work.
At the same time in the water circulation system: there is a lot of gas, if not easy removal of air resistance, resulting in partial or whole system circulation is not smooth and uneven, and the damage of the equipment and pipeline; on the other hand the water containing oxygen makes the heating (cooling) equipment, pipe and steel radiator etc. the terminal equipment corrosion, perforation, Water Leakage directly affects the safety of the whole system. Degassing unit in the equipment according to Henry's Law: in a certain temperature and pressure water in a certain amount of gas dissolved when increasing the temperature or pressure is reduced, the principle of gas dissolved in water will be reduced; in the case of not changing the water temperature through the vacuum equipment, will be released free and dissolved gases in water. Then through the automatic exhaust valve exhaust system. After the unsaturated water, the gas in the absorption system is used to seek the balance of water and air. So that all the water in the system can be removed, and the system is stable and safe.
Three, equipment characteristics
1 automatic constant pressure, automatic water supply, automatic drainage system, automatic removal of free gas and dissolved gas.
2 set the operating parameters, suitable for any constant pressure water supply. 3 save energy: automatically read system information, only when necessary to start the device running. 4 degassing efficiency and deoxygenation efficiency >99%. 5 can greatly shorten the heating or cooling system after the initial water injection exhaust time, is conducive to the initial commissioning of the system. 6 remove the gas in the system, to prevent gas resistance, to ensure the normal operation of the system stable and reliable. 7 eliminate pump cavitation, reduce system noise.
8 due to the removal of oxygen in the water, it will reduce the oxygen corrosion of the system and prolong the service time of the equipment. 9 single for system capacity up to 150m can be used in parallel multiple fand. 10 covers an area of small, easy to install and use, fully automatic operation, safe and reliable, easy maintenance.
Four, equipment function
A set of automatic constant pressure water, vacuum degassing and expansion, four in one, to cancel the expansion tank and large pressure tank, simplify the system, prolong the service life of the pipeline and equipment, to improve the efficiency of heat transfer equipment to eliminate noise and gas resistance phenomenon of the pipeline system, a single processing system degassing the largest volume to 150m with a fand. Preparation of double vertical pump water supply function, frequency control and general control optional.
