Automatic constant pressure filling water principle of vacuum degassing device can adjust the volume of air conditioning water system caused by temperature change and expansion and contraction. The air conditioning water system pressure is constant set point; Through the pressure sensor real-time detection system, and the output signal to micro processing center, open the overflow solenoid valve open decompression or constant pressure pump pressure, thus stable system pressure, the stability of the air conditioning system.

A, automatic constant pressure water inlet vacuum degasser principle overview

Automatic constant pressure water inlet vacuum degassing device principle is a kind of voltage stabilizing filling water device, it is mainly composed of buffer tank, pump, pressure switch, intelligent control box, valve, the base and line; Products are widely used in air conditioning, heating system, residential quarters, factories, commercial, hotel, hospital facilities multi-story or high-rise buildings water supply, fire water, it can replace traditional expansion tank water tank, can decrease The Times of the primary system circulating pump start-up and adjustable system of water pressure, water volume, easy to realize automatic filling water.

Second, automatic constant pressure water inlet vacuum degasser principle works

Constant pressure water inlet device using the expansiveness of the gas. When the constant pressure water inlet device after the installation is complete, you can switch to pressure P2 (water pump stop pressure), UCLA P1 (pump start-up pressure) and the set pressure value (specific value can be set according to the customer), after completion of the work can be connected to the power began to water. Start the pump, pipe network and voltage tank filling water to buildings, because the water is incompressible fluid, with the water increasing, expanding the volume of water chamber, capsule shape of the diaphragm are outward expansion and the extrusion chamber, make its volume shrinking, tank pressure is increasing, when reach the set pressure P2, the pump automatically stop the pump. Due to the volume of water through the system, the system pressure decreases, the gas expansion tank will be a bag of hydraulic system. Such water chamber volume shrinking, shrinking diaphragm capsule form, when the water indoor almost exhausted, tank pressure is to design pressure P1, the pressure switch contact met set pressure, the pump automatically open, the water filling the pipe network and water room again. Repeat the above process, water supply system with water. The above operation process is controlled by the pressure switch electrical control box pump start-up and implemented.

Three, automatic constant pressure water inlet vacuum degasser principle, product features

1) an inflatable can keep the long-term use, the user does not need the other set aeration equipment.

2) tanks for airtight device, gas water contact, not pollution to water quality is not affected by the outside world.

3) cover an area of an area small, investment saving, quick installation, simple operation, easy maintenance.

4) save life building roof and fire cistern, is advantageous to the aseismic and buildings is beautiful; Can abate noise, cavitation flow, pipeline resistance and water hammer effect, avoid the phenomenon of water meter idling measurement are not allowed to appear.

5) flexible, installation position is not subject to height restrictions, easy to reconstruction, expansion and migration.

6) automatic control, easy to use, reliable operation.

7) the supply pressure needed to water and fire hydrant, water supply is reliable.

Four, automatic constant pressure water inlet vacuum degasser principle, technical parameters

Five, the structure size

Automatic constant pressure water inlet vacuum degasser principle function and principle:

Constant pressure water device of constant pressure function: regulates air conditioning water system caused by temperature change and volume expansion and contraction, make air conditioning water system pressure is constant set point;

Through the pressure sensor real-time detection system, and the output signal to micro processing center, open the overflow solenoid valve open decompression or constant pressure pump pressure, thus stable system pressure, the central air conditioning system of stable work;

Constant pressure exhaust gas hydrate device features: high pressure circulating water in the process of exhaust gas under pressure into the normal pressure tank, air separation, water product gas through the exhaust valve atmosphere, can discharge gas in the system not only can vent gas from hydrate;

Constant pressure water device of hydrating function: due to exhaust gas and system dripping water can be lost by the control unit real-time monitoring, once below the set value, both by the constant pressure pump automatically from the diaphragm tank water supplement. Diaphragm tank how much water can be real-time monitoring by weighing sensor, water set during the installation.

Automatic constant pressure water inlet vacuum degasser principle role:

Constant pressure constant pressure function of filling water: when the medium is heated up, because the temperature can make the volume expansion of the whole system pressure height, when the pressure is to set pressure (P0 + 0.2 bar), the equipment of pressure solenoid valve is opened, the system of discharge volume expansion due to heating medium to the atmospheric pressure inside the tank, to maintain the system pressure constant.

Hydrating function of constant pressure water: when hot water after cooling equipment cooling, the temperature drop and shrinkage, the system pressure drop, when the pressure drop to set (P0 to 0.2 bar), the pump will be stored in the atmospheric pressure inside the tank of the gray other peripheral supplies the water through the pump to the system, to maintain the system pressure constant.

Vacuum degassing function of constant pressure water, can be add in the system from the system with water or water in a vacuum degassing, eliminate system of dissolved gas and free gas, large bubbles, etc., to protect equipment and system stable operation.

Softening function of constant pressure water: filling water softening water devices are installed on the pipeline system (optional), for water softening system outside water.

Automatic constant pressure hydrating principle of vacuum degassing equipment characteristics of the equipment:

1. Don't import rubber cyst of inert gas, applicability, province work material.

2. By spraying a degassing, secondary circulating degassing degassing of the limit.

3. Water storage tank for atmospheric pressure tank, a pressure tank shell thickness thinning, can save steel, atmospheric tanks for unconfined equipment at the same time, the sexual pressure equipments.

4. Total volume pot rubber pouch storage water tank shell are equal, in the case of the adjustment of the same volume, atmospheric tank volume was only about 1/3-1/2 expansion tank volume.

5. The main capsule structure is used to attach tank, and is very different from the traditional diaphragm tank, diaphragm type expansion pipe is move up and down through the membrane to absorb the pressure fluctuations, half direct contact and the media of tank, the diaphragm tank in use after a period of time will be corroded badly, and capsule type expansion is a complete capsule in jars, through to balance the pressure fluctuation of expansion and contraction of sac, medium do not direct contact with carbon steel shell, hence the tank use for a long time also won't rust.

Automatic constant pressure water inlet vacuum degasser principle applies to the production system of pressurized water supply, fire protection, life, air conditioning system and circulating water system.
