A fluid-driven impeller with supercharging efficiency, low noise, small size and light weight

Abstract

A supercharging, efficient, low-noise, small-size and small-weight fluid drive impeller comprises a main shaft, a cone head assembly and a roller assembly. The supercharging, efficient, low-noise, small-size and small-weight fluid drive impeller is characterized in that the main shaft is a drive shaft with the middle section being a polygonal body and the two ends being cylinders; the cone head assembly is arranged at one end of the polygonal body main shaft part on the middle section, and the roller assembly is arranged at the other end of the polygonal body main shaft part on the middle section; on the cylinder main shaft parts at the two ends, ball bearing blocks used for installation are arranged at the two ends, one end of the main shaft is a power input end and is used for connectinga motor main shaft so that output power can be obtained, and the other end of the main shaft is suspended and is fluid entering space. High-pressure backflow is stopped through a cone head, a flow guiding sheet in the cone head conducts forward flow guiding and supercharging, forward flow guiding and supercharging of blades in the roller assembly and integral impeller fluid leakage avoiding are achieved, and therefore the needed air pressure and the needed air volume can be obtained with high efficiency; and thus, the beneficial effects of supercharging in place, high efficiency, low noise, small size and small weight are achieved. The supercharging, efficient, low-noise, small-size and small-weight fluid drive impeller is suitable for serving as a fluid driving impeller of indoor and outdoor ventilation equipment, pipeline air supply equipment, airplanes, helicopters, ships and other equipment.

Description

technical field [0001] The present invention relates to a fluid driven impeller. Specifically, it is a supercharged high-efficiency low-noise [0002] Small and light weight fluid driven impeller. Background technique [0003] At present, all indoor and outdoor fluid equipment used for ventilation and ducted air supply, including blowers, exhaust fans, ventilation fans, axial flow pumps, etc., generate air volume and pressure from rotating fluid-driven blades or wind wheels. Airplanes, helicopters, and power come from rotating blades, which push back away from the air to obtain forward thrust, and marine propellers, which rotate the blades, reversely push away from the water to obtain forward thrust. This forms the power source of the device. However, these existing blades or wind wheels generally have disadvantages such as poor strength, low power conversion rate, high noise, large volume, and heavy weight, which have been difficult to effectively overcome for a long tim...
