Toothless triangular rotor for flow meter

Abstract

The invention relates to rotors for flow meters, in particular to a toothless triangular rotor for a flow meter. The toothless triangular rotor for the flow meter includes a triangular rotor body; grooves are formed in an upper end surface and a lower end surface of the triangular rotor body; a rotor shaft is positioned in the grooves; and through holes around the rotor shaft are formed in the grooves of the triangular body. The triangular rotor can match a bearing in the metering room through the rotor shaft, and rotation of the rotor can be achieved; the grooves formed in the rotor can reduce the weight of the rotor, and can provide moving gaps for an eccentric bearing disc; and the contradiction of rotation and revolution of the triangular rotor can be skillfully solved during a moving process. The triangular rotor is simple and practical in structure, is easy to manufacture, and can simplify the structure of the metering room.

Description

technical field [0001] The invention relates to a rotor for a flow meter, in particular to a toothless triangular rotor for a flow meter. Background technique [0002] The original rotor of positive displacement flowmeter is mainly driven by gears, and the internal structure of the rotor is an internal tooth type. Since this meshing rotation mode is applied to the flowmeter, it not only appears to be complicated in structure, but also increases the difficulty of processing, and also It is not suitable for complex metering environment and medium composition. For example, crude oil contains a lot of corrosive substances and has a large sand content. If this structure is adopted, it will easily cause gear wear or jamming during use. Contents of the invention [0003] In order to solve the above problems, the present invention provides a toothless triangular rotor for a flow meter. [0004] The present invention is realized by adopting the following technical scheme: a tooth...

[0002] The original rotor operation mode of positive displacement flowmeter is mainly driven by gears, and the internal structure of the rotor is an internal tooth type. Since this gearing rotation mode is applied to the flowmeter, it not only appears to be complicated in structure, but also increases the difficulty of processing. Not suitable for complex metering environment and medium composition

For example, crude oil contains a lot of corrosive substances and has a large sand content. If this structure is adopted, it will easily cause gear wear or jamming during use.
