Description

Improve interior gear electromagnet's flowmeter

Technical Field

The utility model relates to a flow meter technical field, in particular to improve interior gear electromagnet's flow meter.

Background

When fluid passes through the rotating gear in the middle of the flowmeter, the gear is pushed to rotate, the electromagnet on the gear is intersected with the circuit plug-in unit under the counting display to generate magnetic induction, and the counting display starts to count.

A shaft sleeve made of PEEK material is pressed on a center hole of the existing gear, and then the gear provided with the shaft sleeve is sleeved on a shaft at the center of a shell. When the flow meter is used for too long time or is used in an environment, the temperature of the flow meter body rises, the shaft sleeve made of PEEK deforms, the fit clearance between the PEEK shaft sleeve and the shaft is enlarged, the concentricity is enlarged, and the flow is unstable.

The electromagnet on the existing gear is exposed out of the surface of the gear, and is directly soaked in fluid when in use, so that the phenomena of corrosion, oxidation, rusting and the like are caused, and the gear is easy to rotate unsmoothly, has weak induction signals and is blocked.
