Abstract

The invention provides a high-stability efficient water turbine impeller and a water inlet component thereof. The high-stability efficient water turbine impeller comprises the water inlet component and an impeller body, the water inlet component comprises a water turbine pump and a water inlet sleeve, a sliding groove is formed between the water turbine pump and the water inlet sleeve, the impeller body comprises mounting plate and six blades, each blade comprises a first circular arc section and a second circular arc section, a push plate has a trilateral section, the section comprises a first edge, a second edge and a third edge, and stabile plates with guide blocks are arranged on the blades. The impeller is simple in structure and reasonable in design, the impeller body rotates along the sliding groove through a stabile block in a guiding manner, stability is greatly improved when the impeller body rotates, the blades are designed by the aid of a double-arc-shaped mode, kinetic energy collection efficiency of the water turbine can be effectively improved, a direction of water flow can be normalized by the push plate, the strength of turbulent flow in a volute can be reduced, discharging efficiency of the water flow is improved, a buffering bent pipe is matched, impact of the water flow is reduced, and the power conversion efficiency of the water turbine is improved when theservice life of the water turbine is prolonged.

Description

technical field [0001] The invention relates to a water turbine assembly, in particular to a highly stable and efficient water turbine impeller and a water inlet assembly thereof. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy, and it belongs to the turbomachinery in fluid machinery. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, the water in the upstream reservoir is led to the turbine through the diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. [0003] Currently used water turbines, especially small water turbines, generally have the disadvantage of low water kinetic energy collection efficiency, resulting in low conversion rate of electric energy, and the unconverted kinetic energy is easy to impact the water turbine impeller, resulting ...

Problems solved by technology

[0003] Currently used water turbines, especially small water turbines, generally have the disadvantage of low water kinetic energy collection efficiency, resulting in low conversion rate of electric energy, and the unconverted kinetic energy is easy to impact the water turbine impeller, resulting in damage to the impeller. Moreover, the water flow in the water turbine volute The lack of regular guidance is prone to turbulent flow, which aggravates the low power conversion rate. At the same time, the stability of the impeller of the old-fashioned water turbine is relatively poor, which affects the use effect
