Vacuum Products vacuum boiler boiler is a hot water boiler, water heater, also called vacuum, vacuum boiler from the basic principles of the 1972 Zurich University of the invention. Vacuum boiler is mainly used for civilian heating, can be used in specific situations hotels, residential areas, commercial establishments like heating, sanitary hot water heating. Vacuum boiler vacuum boiler works a negative pressure vacuum is formed in a closed environment inside the furnace, the heat medium is filled in the body of water. Or otherwise heated by combustion heat medium water, heat medium water is heated to generate steam, the water heat exchanger heated by the pipe of the condensing heat exchanger, to achieve the supply of hot water. Vacuum boiler leak leak detection method described may be employed soapy water pressure. Wipe the first leak site (e.g., wire head, flange, etc.), and find a diameter 3-4mm thick sheet or plank is placed between the disk and the blade is about 80mm, prevent the boiler pressure proof sheet is bulged blade punctured. Allow operation of the burner, turn off the vacuum and high vacuum diaphragm valve means, so that the pot 0.05MPa pressure rise, closing the burner, pressure, liquid soap applied with a brush in the presence of all possible leak site, carefully, if leakage point will produce bubbles. Note that the pot pressure should not exceed 0.1MPa! For an examination site: explosion-proof valve, high vacuum diaphragm valve (hose connection), the furnace outfall seat, mirror, automatic vacuum device, a pressure control means on the furnace level, water temperature and other probe mounting interface. Found leakage diaphragm valve position required to open the high vacuum vapor discharge, reinstall the leak. After installation is complete again with soap and water leak detection method for detecting pressure, missing dots after confirmation, closing the diaphragm valve is opened after the high vacuum vapor release, and the plates come between the blade and the disk, closing the circulation pump, and then evacuated so half an hour to run the apparatus evacuated to a vacuum state.

1. What is a vacuum? Divided into physical vacuum and vacuum industrial vacuum. Vacuum means that no physical space of any particle. Industrial vacuum means a pressure lower than the atmospheric gas space standard. It refers to a thin gas state. It is usually obtained by a special pump. Vacuum vacuum boilers are industrial vacuum.
2. What are vacuum hot water boiler? Vacuum boiler is a vacuum environment, the sealed furnace body negative pressure, so that the furnace body is filled with heating medium water. The heating medium water heated by burning or otherwise, and then evaporated by the heat medium and condensed water into a heat exchanger, then heating the water to be heated by the heat medium water. Vacuum heat boiler indicated: oil, gas, natural gas, natural gas, electricity -> combustion (heat conversion)> heat medium water -> steam condensation heat after boiling -> heat -> Heat Conduction -> vacuum boiler water working principle: the use of water at low pressure characteristics of a low boiling point, rapid heating of the heat medium water sealed furnace body, the heat medium temperature steam generated by the boiling water, the steam condenses on the heat transfer tubes within the heat transfer tubes heating the cold water, to supply hot water purposes. Vacuum boiling point of water and the corresponding table: structural diagram of the degree of vacuum (Kpa) 0-31-54-70-81-89-94-97-99-101 boiling point of water (℃) 10090807060504030200 vacuum hot water boiler:
