Novel turbine flowmeter with self feedback system

Abstract

The invention discloses a novel turbine flowmeter with a self feedback system. A front flow guiding member, a central shaft and a back flow guiding member are successively mounted in the central through hole of the turbine flowmeter body. A turbine wheel sleeves the central shaft through a flat key fixing sleeve. Two ends of the central shaft are mounted in the middle through hole of the turbine flowmeter through supporting frames and are radially fixed. Rolling bearings are mounted between two ends of the central shaft and the supporting frames. The central through hole of the turbine flowmeter body between the supporting frame which is next to the side of the back flow guiding member and the back flow guiding member is provided with an inner flange. The front flow guiding member is internally provided with an air bag for controlling flow. The air bag is connected with a rubber pipe. A rubber pipe penetrates through the turbine flowmeter body and is connected with an air source through a regulating valve. A flowmeter head is arranged outside the turbine flowmeter body. The flowmeter head and the regulating valve are connected with a comparator. The turbine flowmeter is provided with a feedback system and the flow can be adjusted. Furthermore the turbine flowmeter has advantages of reducing mounting precision error, reducing impact damage, prolonging service life, saving production cost and maintenance cost, realizing relatively high rectification effect and guiding function, and obtaining high adaptability and multiple functions.

Description

technical field [0001] The invention relates to a flowmeter, in particular to a new type of turbine flowmeter with a self-feedback system, which can obtain the required flow according to the set flow value. Background technique [0002] Turbine flowmeter is a speed type flow meter. The fluid impacts the turbine blades to make the turbine rotate. According to the relationship between the angular velocity of the turbine rotation and the flow value, the flow value is converted into the flow value according to the angular velocity of the turbine rotation. With good repeatability and other characteristics, it is one of the flowmeters with high precision in the flowmeters of today's era. [0003] Turbine flowmeters can be widely used in petrochemical and other fields. Due to the advantages of wide measurement flow range, compact structure, simplicity, and long service life, turbine flowmeters are currently one of the most widely used flowmeters. With the development of my country...
