Operation and Maintenance of Gas Verabar Flowmeters

<

  Verabar flowmeters always have a good advantage in plug-in flowmeters due to their unique advantages. The Verabar flowmeter is basically suitable for the measurement of all pipeline specifications on the site. The application on large-diameter pipelines shows more advantages. It is applicable to the flow measurement of various liquids, gases, and steam, especially ultra-low temperature, high temperature, high pressure, and humid fluids. The measurement of the medium. However, at the same time of application promotion, customers will also encounter the same problem of how to maintain. The following is a summary of the work and simple maintenance of Veripar flowmeter before it is put into operation:
1. Check the installation of the flow meter: After completing the installation of the Power Bar flowmeter, it must be inspected carefully. The welding is required to be firm, the direction is correct, and the test pressure does not leak.
2. Instrument calibration: read the manual of intelligent flow integrator carefully. According to the calculations attached to the Verabar flowmeter, the parameters in the intelligent flow totalizer are set correctly to ensure that the totalizer can correctly calculate and display the flow. If you go directly to the computer, you need to set the input data format and the corresponding compensation method inside the computer.
3. The instrument wiring is correct: The power flow meter and the flow totalizer together form a measurement system. Please check it repeatedly and make sure it is correct before putting it into operation.
4. System warm-up: After the commissioning preparation is completed, the measured medium is filled with the process pipeline, and the power flow meter is temporarily closed. At this time, the balance valve of the three-valve bank should be opened, and the high pressure valve and the low pressure valve are closed. status. Turn on the instrument and warm it up for 15 minutes.
5. System operation: After the preheating is completed, open the high pressure valve and low pressure valve of the three valve group, fill the differential pressure transmitter with the measured medium, open the drain valve after the differential pressure transmitter, and quickly discharge the dirty liquid or gas. Close the blowdown valve, and then close the balance valve of the three valve group, the transmitter will enter the measurement state, and the flow totalizer will also enter the working state, showing the media flow in the pipeline.

Polyester Spunbond Non-woven Fabric Production Line

PET polyester non-woven fabric equipment mainly includes: polyester filament non-woven fabric machinery, polyester staple non-woven fabric machinery. The produced non-woven fabric has the characteristics of high strength, high temperature resistance (can be used in 150 ℃ environment for a long time), aging resistance, ultraviolet resistance, high elongation, good stability and permeability, corrosion resistance, sound insulation, mothproof, non-toxic, etc. In addition, there is a very special physical property: anti gamma ray. The surface is smooth and glossy. It has excellent physical and mechanical properties in a wide temperature range. Its long-term use temperature can reach 120 ℃, and its electrical insulation is excellent. Even under high temperature and high frequency, its electrical performance is still good, but its corona resistance is poor, creep resistance, fatigue resistance, friction resistance, and dimensional stability are good.
