What are the role in the thermometer in the hot water boiler system?

Thermometer is an instrument of measuring medium temperature, the thermometer in the hot water boiler system is usually installed on the boiler outlet, water segregator and Siamese ( Or the total main backwater) , economizer classy place, its main role is to test the hot water temperature and water temperature. For boiler operators adjust hot water boiler's running status, ensure the normal operation of hot water boiler system. Usually installed on the hot water boiler with double metal thermometer thermometer, mercury thermometer glass tube used in industry and pressure type thermometer. The bimetallic thermometer measurement range is larger, and more durable, can be divided into axial, radial and universal type. General as long as the bimetallic thermometer installed in proper place is good, but should pay attention to regularly check the thermometer, in case the materials such as scale affect its accuracy. Industrial glass mercury thermometer, is usually used for hot water boiler system of internal standard type glass mercury thermometer, rod type glass mercury thermometer to test more liquid or gas temperatures. 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, best location in the center of the tube bulb parts, installation time surface should be easy to observation direction. Pressure type thermometer, mainly by thermal bag, capillary and the spring pressure gauge. Pressure type thermometer is suitable for measuring the temperature of the medium over a long distance, installed in the hot water boiler exit, more show that temperature stress when installation the dial can be placed in the lower position for easy reading.
