Constant pressure water plant equipment using the system hydrostatic pressure head as the initial design of the expansion tank, as in the fixed line terminal expansion tank pressure head within the guarantee system uses hot water not vaporized pressure. First, start up the pump to the initial runtime system and pressure tank filled with water in the water chamber constant pressure water device size, the system is filled with excess water is squeezed into the capsule. Constant pressure water device acts as incompressible nature of water, with the increasing amount of water, the volume of the water chamber is also continuing to expand and compress the gas chamber, the pressure tank has also been increased. While the water system: on the one hand there is a lot of gas constant pressure water device selection, if not removed prone to vapor lock constant pressure water equipment, resulting in partial or poor circulation of the whole system and Enthusiasm, as well as equipment and damage to the pipeline; on the other hand oxygen contained in the water so that the heating (cooling) equipment, piping and steel radiators and other terminal equipment corrosion, perforation, leakage directly affects the security of the entire system. Constant pressure water device samples, Suizhou constant pressure water equipment, Wuhan Han Wei Wei Li Yuen Yuen provided by the Wuhan-being of Equipment Co., Ltd. Wuhan Han Wei Li Yuen-being of Equipment Co., Ltd. (www.whhwly.com) strong, credible, in Wuhan, Hubei fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Wuhan Han Wei Li Yuen and you hand into the brilliant, for a better future!
