Description

Technical Field

[0001] The invention relates to the technical field of flowmeters, and in particular to a split-type azimuthally adjustable gas turbine flowmeter. Background Art

[0002] The gas turbine flowmeter is an instrument that measures gas flow based on the principle of turbine rotation. It is widely used in natural gas, petrochemical, electric power and other industrial fields. Accurate measurement of gas flow is of great significance to ensure the safety of the production process, improve energy efficiency and reduce costs. Traditional gas turbine flowmeters usually calculate the flow rate by directly measuring the change in gas speed when it flows through the turbine. This process requires that the installation of the flowmeter must ensure that the turbine can run smoothly in the airflow. However, the existing gas turbine flowmeters still have the following defects in practical applications: First, due to the complexity of the pipeline installation environment, airflow characteristics, and on-site installation conditions, the orientation and installation angle of the gas turbine flowmeter have a great impact on the measurement accuracy and performance of the flowmeter. Existing gas turbine flowmeters are mostly fixed designs, and the installation orientation cannot be flexibly adjusted according to actual conditions; especially in irregular pipelines, the installation and adjustment of the flowmeter are difficult, which often leads to inconvenient installation or inaccurate measurement results. The difficulty in orientation adjustment leads to the inflexible installation of the gas turbine flowmeter, inconvenient adjustment, and inability to meet the installation requirements under different working conditions.

[0003] Secondly, existing gas turbine flowmeters usually adopt an integrated structural design, and the installation and disassembly of the entire gas turbine flowmeter is relatively complicated; in many application scenarios, the installation and maintenance of the gas turbine flowmeter need to be carried out frequently, and this integrated structure makes the disassembly, inspection and maintenance of the equipment cumbersome and time-consuming, especially in some small spaces or special environments.
