Air conditioning constant pressure tank | constant pressure units | floor-expansion tank | constant pressure water equipment

First, David Cheng constant pressure water equipment systems: a bladder pressure tank, two pumps, a set of cabinet, two pressure gauges, two check valves, two valves, piping systems and base Block and other components. Second, David Cheng constant pressure water supply pump device selection: automatic fill water supply pump circulating water system can be considered 1%, 3% pay accident circulating water system to consider directly into the circulating pump up the entrance, water pump head height should pay point and the highest point of the system plus the amount of 3 ~ 5mH2O wealthy consideration. Third, David Cheng constant pressure water system pressure tank Selection: maximum working pressure should be greater than the pressure tank fill pump head. Inflation pressure shall meet the requirements of the system pressure. The volume of the tank should the tank body water volume selection, the body water volume of the tank volume of the expansion tank should select, i.e., the volume of water inside the tank should be able to accommodate the amount of expansion of the water system. Subject to detailed pressure tank volume adjustment is calculated according adjust the volume to match the size of a volume of the pressure tank. Adjust the volume is small, would not achieve the expansion of the role of regulating the volume is too large, increase investment. Four, Hong Cheng constant pressure water device classification: single pot double pump constant pressure water equipment, dual tank twin pump constant pressure water equipment, three cans of double-pump constant pressure water equipment. HCDY series products can be based on user requirements and the size of a can of water in a pump, two pumps jar, two pump cans, four pump three cans (two pump three cans) and other different settings, set two pumps of both alternately run separately, can also be run in parallel, so that prolong the life of the equipment, but also to meet the user's requirements to ensure safe water supply and system uptime. Fifth, the constant pressure water system works: the use of the system as a design initial hydrostatic pressure head inside the expansion tank, as in the fixed line terminal expansion tank pressure head within the guarantee system uses water pressure is not vaporized. First start up the pump to the system and the initial running water chamber pressure tank filled with water, the system is filled with excess water squeezed inside the capsule. Because of the incompressibility of the water, with the increasing amount of water, the volume of the water chamber has been the expansion of the compression chamber, the pressure tank also continuously increasing. When the pressure reaches the design pressure, through the pressure controller makes up the water pump is turned off. When the thermal expansion of the water within the system so that the system pressure rises above the design pressure, the excess water to drain through the safety valve makeup tank recycling, when the water in the system due to leakage or temperature drop volume is reduced, system pressure is lowered, the capsule The water is constantly pressed into the pressure drop pipe network complement system, when the system pressure is the lowest pressure allowed to design when making up the pump by pressure controller to restart the pipeline network and water pressure tank, again and again. Vacuum degasser with a reasonable constant pressure water is composed of vacuum exhaust unit. Six, Hong Cheng constant pressure water equipment Features: 1, good sealing performance tank, once inflated long-term use 2, the pipe network can automatically eliminate water hammer and noise was 3, using non-toxic capsules, to ensure water quality from pollution 4 , small footprint, easy installation and construction of complete sets of equipment 5, with vertical pumps, low noise operation normal seven, Hong Cheng fixed pressure water device is suitable for a range of industrial and civil construction production and living fire water system. 2, the hot water supply systems, water heating systems, air conditioning systems. 3, as the high-rise building water supply system, water hammer noise cancellation device. 4, ideal for rural water supply, and construction, temporary job flow of water supply equipment. 5, the fountain of tourist facilities and tourist spots, forest rural irrigation systems. 6, the central heating system for hot water floor heating expansion tank.
