High pressure titanium bulb floater type light display water level gauge

Abstract

The invention discloses a high pressure light display water level gauge with titanium bulb floater, which is a water Level measuring device for high-pressure boiler drum of large-scale thermoelectric generating set. The invention comprises a magnetic signal receiving element and a titanium bulb floater with diameter of 60 mm, the magnetic signal receiving element is electronically connected with a photoelectric display and also connected with an ultra bright two-color lighting surface, the ultra bright two-color lighting surface is used as a water level indicating device, and a magnetic steel with weight less than 1 g is freely disposed inside the titanium bulb floater or a soft magnetic material coating with weight less than 1 g is coated on the outer wall of titanium bulb floater. The application method comprises placing the titanium bulb floater a measuring tube connected with a high pressure and high temperature boiler drum, and disposing the magnetic signal receiving element outside the measuring tube for receiving the magnetic signal from the titanium bulb floater. The invention has the advantages of low manufacturing cost, rapid water lever dynamic response at high temperature, and lower water level measurement error.

Description

technical field [0001] The invention relates to a liquid level gauge, in particular to a high-pressure titanium bubble float type light-display water level gauge, which is a water level measuring device for a high-pressure boiler steam drum of a large thermal power generating set. Background technique [0002] At present, because medium and low pressure steam drums are usually used in small and medium-sized thermal power generating units, such units have high coal consumption, high pollution, and low efficiency, and have been clearly phased out by the state, and replaced by large and super large thermal power generating units. The main development goal of the supply. The boiler drum pressure of large-scale thermal power units reaches above 17Mpa, and the temperature reaches above 385°C. In this harsh environment, the measurement of high-temperature and high-pressure steam drum water level has always been a technical difficulty in the entire thermal power industry. There has ...
