Abstract

The invention provides a device for improving the stability of a liquid flow. The device for improving the stability of the liquid flow comprises a shell, a flow stabilizing assembly, a flow fine adjustment assembly and a honeycomb-shaped channel. The shell comprises a shell front section and a shell rear section sliding relatively; the honeycomb-shaped channel is arranged on the cross section ofthe shell rear section; the flow stabilizing assembly comprises a main shaft, a front bearing and a rear bearing; the main shaft comprises a main shaft front section and a main shaft rear section inserting mutually and sliding relatively; the main shaft front section and the main shaft rear section are connected with the shell; the flow fine adjustment assembly comprises a fine adjustment impellerand an impeller shaft; the fine adjustment impeller is arranged on an outer ring of the front bearing in a sleeving mode; six cylindrical open holes are formed in one side of the impeller shaft; sixcylinders are arranged on the inner side of a connecting ring; an inner ring of the connecting ring is arranged on the rear bearing in a sleeving mode; and six circular slots are equidistantly formedin an outer ring of the connecting ring. The device for improving the stability of the liquid flow provided by the invention has the beneficial effects of elaborate design, lower manufacturing cost, and capabilities of reducing a turbulence effect and effectively improving the stability of the liquid flow, and has a flow fine adjustment function with higher accuracy.

Description

technical field

[0001] The invention relates to the technical field of experimental equipment for fluid mechanics, in particular to a device for improving the stability of liquid flow. Background technique

[0002] Fluid mechanics experimental instruments are widely used in various universities and research institutions. Today, there are several major brands of fluid mechanics experimental instruments in the world, such as Tecquipment, Elcometer, Armfield, OHAUS, etc. These experimental instruments mainly include consoles, water pumps, flow monitoring devices, hoses, and experimental areas. The water pump is responsible for pumping the liquid into the circulation; the flow monitoring device measures and records the flow data and transmits it to the console; the console is used to adjust the flow rate and display flow and other data; the hose is connected to various devices in the cycle; the experimental area is used for experiments , provided to the observer data.
