Problems solved by technology
Smart water is mainly a dry water meter. Due to structural reasons, the impeller rod of the dry water meter is long, which causes unstable rotation. The concave hole of the shaft sleeve on the water baffle is easy to trap air, the initial flow is large, and the rotation of the small flow is unstable. , the accuracy R value is relatively low
In addition, the traditional water meter impeller box and baffle plate have single damping, and there is pulse water flow damping, which causes instability to the impeller rotation

The invention relates to the field of water meter, and particularly relates to a cycloid impeller gyroscope principle object networking water meter core, which comprises an impeller box, a filter cover, a water-proof plate, an impeller component and a pulse induction component, wherein the impeller component comprises an impeller body, an upper shaft and a blade, wherein the blade is a cycloid curved surface. The cycloid impeller gyroscope principle object networking water meter core blade is a pendulum linear curved surface, which not only increases the stress area of the water flow, indirectly increases the rotation moment of the impeller, reduces the starting moving flow rate, improves the metering precision of the water meter, but also the water outlet damping is continuously and smoothly smooth. Besides, the impeller assembly adopts a gyroscope principle to design, the distance L between the apex of the upper shaft and the center of gravity of the impeller assembly is smaller thanthe nominal diameter D of the impeller assembly, which reduces the moment of inertia, breaks the resonance point, and reduces the centrifugal force caused by high-speed rotation, so that the impellerassembly rotates more smoothly.
Description
technical field [0001] The invention relates to the field of water meters, in particular to a cycloidal impeller gyroscope principle Internet of Things water meter movement. Background technique [0002] In recent years, society has developed rapidly, science and technology have continued to advance, the water meter industry has combined microelectronics and sensor technology, and smart water meters have achieved breakthrough development, gradually realizing unmanned meter reading, automated management, and leakage management. Smart water is mainly a dry water meter. Due to structural reasons, the impeller rod of the dry water meter is long, which causes unstable rotation. The concave hole of the shaft sleeve on the water baffle is easy to trap air, the initial flow is large, and the rotation of the small flow is unstable. , the precision R value is relatively low. In addition, the traditional water meter impeller box and water baffle have single damping, and there is pulse...
