Intelligent temperature and high pressure boiler drum level gauge (welded connection / flange connection)

CR-6031 intelligent boiler drum level gauge boiler boiler drum level gauge is an important ancillary equipment. Because boiler water vaporization loss at high temperatures, water and steam is large, we must continue to add water, the water level in the boiler to maintain a certain height, the water level is too low, there is the risk of boiler explosion. However, there are many defects can not be improved long-standing tradition of boiler drum level measurement methods, mainly in the following areas: (i) the defect dual chamber balanced container measurement of differential pressure level: 1, can not measure the implementation of the whole working conditions , there is "false water level .." measure in the boiler start, stop, emptying, platoon, accident and other unstable operating conditions to establish a long and stable differential pressure time, recovery time is longer or simply can not build a normal differential pressure , it requires manual intervention and other issues. 2, under steady operating conditions, due to structural constraints, can not completely solve the water side of the system due to the absolute temperature measurement and compensation issues caused errors. In the boiler missing, filled with water and other accident conditions, measurement error is too large could have serious consequences. 3, complex structure, static sealing points, and the presence of large-scale construction in winter insulation problems. 4, measuring long delay, not instant reaction boiler water level changes, measuring the difference between the signal quality of regulation. 5, the instrument requires regular sewage and sewage recovery after a long time. Since the instrument at high static pressure, small-scale conditions, so small vacuum tubes are unbalanced pressure will cause large errors in the measurement results. 6, due to the exothermic condensation tube, high cost. (Ii) defects industrial video-assisted measurement of an industrial video-assisted measuring system consists of a quartz tube level gauge, camera and display components. Which itself requires human intervention and by the field of environmental impact (such as cleaning), etc. 2, can not see when the real level of boiler operation, the level seen in the level must be false. This difference is due to the inner and outer containers of liquid density cooling measures to prevent erosion bullied taken quartz body caused by the formation of error of about 25% visible results. (Iii) defects, electric contact level gauge measurement 1, a segment display, there is no precision at all; 2, high failure rate, since the electrode corrosion or fouling in water, usually around six months must be replaced. 3, there is a false level and the phenomenon of false alarms, water in the boiler often in rollover state, water vapor mixture to form electrical contacts water level gauge error display and phenomenon of false alarms. 4, sealing points, wire and more maintenance workload. These flaws are due to the measurement principle itself there are deficiencies, it can not be improved. In the non-normal conditions for the safe operation of the boiler caused great problems. To solve the problems of drum level measurement, Henan Long Run Automation System Co., Ltd. for the boiler drum level measurement and control condition patented design and production CR-603 列 intelligent capacitive boiler drum level gauge. CR-603 series of intelligent capacitive boiler drum level gauge is the use of advanced, patented capacitive sensing technology has the full measure automatic compensation function made of. It solves the traditional capacitive level gauge measurement systems insurmountable temperature drift large variation in the dielectric constant of the measured medium on the measurement, testing linear poor and need artificial field calibration and other issues. Boiler drum level can achieve safe, reliable and accurate measurement and control of all operating conditions, to ensure boiler safety, efficiency, energy-saving operation is important. It can be widely used in a variety of industrial drum, high plus, plus low conversion furnace pressure vessel level monitoring and control. Full range of intelligent boiler drum level gauge from the applicable working conditions and the price is divided into three series: CR-6031 series, CR-6032 and CR-6033 series series, this series of explosion-proof electrical products by the State Quality Inspection Center qualified, made explosion-proof certificate. CR-6031 intelligent boiler drum level gauge using tomography technology, through a special sensor to scan and analyze the dynamic level gauge liquid, gas, dielectric constant and temperature, dynamic compensation. After comparison operation system software, 4 ~ 20mA standard current signal output proportional to the level of the boiler and four SPST solid state relay switch signal. Factors affecting the level meter during operation without the slightest change in dielectric constant, the boiler temperature, the gauge steam disturbance has no effect, more than one-thousandth of its measurement accuracy, long-term stability is very Well, almost no drift, comprehensive performance unmatched by other measurements, it is a full operating conditions, high precision and high reliability of boiler level gauge.
