In order to ensure the long-term normal operation of the gas turbine flowmeter, the turbine flowmeter must always be inspected for its operating conditions, maintenance work must be done, and problems must be eliminated in a timely manner. Gas turbine meter maintenance method: 1 〠Before the turbine flowmeter is put into operation, it is necessary to set the meter factor, check it carefully, and confirm that the flowmeter can be connected without errors and the grounding is good before sending power. 2. Regularly clean, check and recalibrate the flowmeter. The flowmeter with lubricant or cleaning fluid injection port should be regularly injected with lubricating oil or cleaning fluid in order to maintain good operation of the impeller. 3 , monitoring shows the status of the instrument, the assessment shows the meter readings, abnormalities should be checked in time. 4 , keep the filter open. The filter is blocked by impurities, and can be judged from the increase in the reading of the pressure gauge at the entrance and exit of the filter. If the blockage occurs, the blockage will be eliminated in time. Otherwise, the flow rate will be seriously reduced. 5 , for large-flow trade settlement measurement, in order to ensure the accuracy of the flowmeter, the flowmeter must always check. The site should be equipped with on-line calibration equipment, or equipped with a mobile calibration device. Although the one-time investment is relatively large, it is worthwhile considering the long-term economic benefits. Troubleshooting method: 1. The gas turbine flowmeter sensor or the supporting display instrument has no output signal; Failure cause: The wiring is not stuck to the impeller. The detection coil is open or short circuit. The preamplifier is not good. The preamplifier has no power supply or the power supply voltage is too low . The instrument itself is faulty. ; Remedy: Check the wiring is correct Check whether there is debris in the pipeline inspection amplifier maintenance amplifier inspection amplifier or increase the power voltage requirements, inspection display. 2 , the flow rate is zero signal output; failure causes: external electromagnetic field interference pipe vibration caused by the impeller swing back and forth pipe vibration caused by magnetic steel and the coil between the relative removal of transport methods: check the shielding line grounding is good or eliminate interference eliminate pipe vibration Eliminate pipe vibrations. 3 , indicating that the flow does not match the actual flow. Cause: second failure causes adverse preamplifier air or steam mixed with low pressure outlet duct impurities adhered impeller bearing wear, booties pipe failure display instrument failure. Remedy: Elimination of pipe vibrations Repair amplifier Mounting air separator Increase pressure Replace bearing Purge pipe Reconstruct piping indicator.

Inconel, when heated, forms a thick yet stable oxide layer that protects its outer surface from further attack. This makes it the ideal choice for extreme temperature and pressure applications, where steel and aluminum would succumb to thermal creep. Available in numerous grades, the Inconel alloys exhibit shifting characteristics with slight variations in their chemistry.

In its more basic form, typical applications would include the food industry and heat treatment components. When alloyed with other elements, however, further strengthening and stiffening permits its use in the more demanding areas of the marine, aerospace and chemical processing industries. Alloyed to its peak performance, Inconel then becomes the material of choice in the most critical environments of turbine blades, rocket engines and key nuclear industry components.
