Turbine flowmeter failure process solution
In the event of a failure in the use of turbine flowmeters , this time you will be anxious to find instructions, find manufacturers, through a variety of telephones to deal with the following article is the use of feedback Hing Hing instrument combined with customer feedback and Hongxing instrument professional knowledge of this product Teach you how to deal with turbine flowmeter problems.
Hongxing Instrument Co., Ltd. is a high-tech industrial enterprise specializing in R&D, production, sales and service of industrial automation instruments. The company introduced advanced technology from developed countries, combined with its own years of industry experience, developed a variety of automatic control instruments and industrial automation process instrumentation, with advantages of reliable performance and timely delivery, has been widely used in metallurgy, chemical industry, electric power, light Engineering, thermal power, machinery, hydraulics, boilers, paper, pharmaceuticals and other industries.
Problem I. Instability of data: Due to the multiple impurities of coke oven gas, it is easy to crystallize, and the impurities condense on the sensor head, thus causing measurement inaccuracy. As the temperature rises, the impurities volatilize, the sensitivity increases, and the signal increases; on the contrary, it decreases. As a result, data is unstable.
Solution: During the installation and connection of the instrument, ensure that each link is accurate, including the inspection of the site before installation, the wiring of the instrument during the installation, and the grounding line of the system. Real data and accurate output.
Problem 2: Abnormality in the production status of the flowmeter: The temperature of the coke oven gas is high and the humidity is high at the time of delivery. Therefore, there will be moisture in the gas transmission process. The flow of gas drives the water to reciprocate and fluctuate, creating a pulsating flow. When the vortex flow sensor is in such a fluid state, the output data suddenly changes greatly, which cannot reflect the production status at all.
Solution: 1. Regularly drain the pipeline, especially the water in front of the straight section, and set up regular discharge according to specific conditions to reduce the water content in the measurement section as much as possible to eliminate the pulsation in the fluid.
2. Periodically clean the instrument as a whole, and if necessary, purge the sensor head of the instrument to avoid the condensation of impurities at the sensor head. In the cold season, the addition of heat tracing devices in the straight section of the metering section and the meter section also helps to reduce the condensation of impurities at the meter.
The above are some simple examples. To learn more about the flowmeter knowledge or purchase, contact Hung Hing Instruments.
