Boiler type and role of thermometer

Boiler thermometer is an instrument of measuring boiler temperature, in the hot water boiler system installed on the boiler outlet, water segregator and of Siamese, economizer, the main test hot water temperature and return water temperature. For boiler operators adjust running state, in order to meet the requirements of the design of heating temperature. Common boiler industrial pointer thermometer have double metal thermometer, glass mercury thermometer and pressure type thermometer. Bimetallic thermometer is mainly through the nut or flange installed on the equipment or pipeline, through the test tube directly detect the medium temperature. Glass mercury thermometer and share standard type glass mercury thermometer and rod type glass mercury thermometer, used for hot water boiler system, the first rod type used to test the liquid or gas temperatures. Internal standard type is in a glass tube filled with a certain amount of mercury, and then into a vacuum. When inserted the tested medium temperature package heat expansion of mercury, the mercury glass tube liquid level increases, or the temperature drops and the liquid level down, and mark it in a metal sheath tube temperature scale, according to internal standard to measure the medium temperature type glass mercury thermometer. Glass mercury thermometer can be installed in both horizontal and vertical pipe runs, when installed in vertical pipe runs, can with the tube center into 30 Angle & deg; ,45度; 90度; Wait for a variety of installation location, installed in horizontal pipe runs for vertical installation, bulb parts should be at the center of the pipe, surface should be easy to observation direction installation time. Pressure type thermometer, mainly by thermal bag, capillary and the spring pressure gauge. Capillary set within the metal hose, thermal package installed in the interface of tested medium, hot water boiler is generally installed in the hot water outlet, metal hose shall not be close to hot surface area to avoid affect its accuracy, hose bend less as far as possible, and redundant hose rolled into the case, according to temperature stress dial may be placed on a lower position for easy reading. Pressure type thermometer is suitable for measuring the temperature of the medium over a long distance, installed in the hot water boiler exit. Boiler thermometer model is also a lot of, can according to need to customize, choose according to need. Use areas: family, hotels, industrial, heating system, piping, hot water boiler, incubator, etc.
