Abstract
Description
Technical Field
[0001] This utility model relates to the field of turbine flow meter technology, specifically a turbine flow meter with shock absorption function. Background Technology
[0002] A turbine flow meter with vibration damping function refers to a flow meter that adds a vibration damping device to the traditional turbine flow meter to reduce vibration and noise generated during fluid flow, thereby improving measurement accuracy and service life. This type of flow meter typically includes components such as axle, hub, rim, and vibration damper. The vibration damper is the core component; it absorbs and disperses vibration energy through structures such as hydraulic rods, thus achieving a vibration reduction effect. This design not only improves the measurement accuracy of the turbine flow meter but also extends its service life and reduces malfunctions and maintenance costs caused by vibration and noise.
[0003] Referring to the existing Chinese patent with publication number CN213515828U, a turbine flow meter with shock absorption function is disclosed, which relates to the field of turbine flow meter technology. It includes a housing, a preamplifier is provided on the top of the housing, a flow meter body is provided on the top of the preamplifier, a display screen is fixedly connected to the outer surface of the flow meter body, two mounting slots are opened on both sides of the inner wall of the housing, shock absorption components are installed in the interior of the four mounting slots, and a support rod is fixedly connected to one side of each of the four shock absorption components. One end of two of the support rods is fixedly connected to a first flow guide.
[0004] The aforementioned turbine flow meter with vibration damping can effectively reduce the vibration force generated by the liquid during flow by setting up a vibration damping device. Moreover, the vibration damping components are respectively installed on both sides of the first and second guide vanes, which can minimize the vibration force during the flow process and improve the measurement accuracy of the turbine flow meter to a certain extent. However, there are still some drawbacks. For example, when used as a turbine flow meter for water flow, the water flow may experience water hammer effect and easily generate eddies. This causes the force exerted by the water flow on each part of the vibration damping device to be different, which may cause the vibration damping device to tilt and get stuck, affecting the vibration damping effect of the turbine flow meter and the final measurement result. At the same time, it is not easy to judge from the outside when the internal pressure and temperature of the turbine flow meter are too high or overloaded. Therefore, we need to propose a turbine flow meter with vibration damping function. Utility Model Content
