AI Technical Summary

Problems solved by technology

Especially in urban gas metering, medium and high pressure transmission and distribution network metering, and gas pressure regulating station metering, it is widely used; however, at the same time as it is widely used, the gas turbine flowmeter often suffers from insufficient fuel supply due to the lack of regular maintenance by the user. Problems such as timely pressurization and pressure release rate are too fast, resulting in wear or even seizure of shafts, bearings, and impellers

Abstract

The invention provides a gas turbine flowmeter.A volume correction instrument is arranged on a shell, a high-pressure oil supply system is arranged in the shell, an electronic switch for recording the number of oiling times and oiling time is arranged at the high-pressure oil supply system, and is electrically connected with the volume correction instrument, and a comparing module and a reminding module are arranged in the volume correction instrument.The electronic switch provided at the high-pressure oil supply system is connected with the volume correction instrument, the volume correction instrument detects the electrical level state of the electronic switch to judge whether the flowmeter is oiled or not, and if no oiling action exists in preset time, outputting is carried out through a corresponding output interface to remind a user of maintaining and oiling.

Description

technical field [0001] The invention relates to the metering field, in particular to a gas turbine flowmeter. Background technique [0002] The gas turbine flowmeter is a speed instrument with high accuracy and repeatability, simple structure, wide range ratio, small pressure loss, good anti-vibration and anti-pulsation performance, and relatively convenient maintenance. Therefore, it is widely used in petroleum, chemical industry, metallurgy, electric power, industrial boiler, urban gas pipeline network and other industries. Especially in urban gas metering, medium and high pressure transmission and distribution network metering, and gas pressure regulating station metering, it is widely used; however, at the same time as it is widely used, the gas turbine flowmeter often suffers from insufficient fuel supply due to the lack of regular maintenance by the user. Problems such as timely pressurization and depressurization rate are too fast, resulting in the wear and tear of s...
