Intelligent energy-saving fan system based on three-dimensional flow impeller

Abstract

The invention discloses an intelligent energy-saving fan system based on a three-dimensional flow impeller, and relates to the technical field of intelligent fan systems. The intelligent energy-savingfan system comprises a fan frame; one side in the fan frame is fixedly connected with an air inlet cavity; the three-dimensional flow impeller is arranged on the side, far away from the fan frame, ofthe air inlet cavity; the end, far away from the air inlet cavity, of the three-dimensional flow impeller is fixedly connected with a first rotary shaft; the end, far away from the three-dimensionalflow impeller, of the first rotary shaft is fixedly connected with a second rotary shaft; the second rotary shaft penetrates through the fan frame and extends out; the right side of the outer wall ofthe fan frame is fixedly connected with a ventilation cavity; the inner wall of the ventilation cavity is fixedly connected with an air cavity reinforcement pipe; and the interior of the air cavity reinforcement pipe is fixedly connected with a power motor. By means of the intelligent energy-saving fan system based on the three-dimensional flow impeller, the problems that the efficiency of a fan is low, fan and system characteristics are not matched, the fan operates off a high efficiency area, the operating efficiency is low, and valve resistance loss is very high by utilizing a baffle and avalve for throttling are solved.

Description

technical field [0001] The invention relates to the technical field of intelligent fan systems, in particular to an intelligent energy-saving fan system based on a ternary flow impeller. Background technique [0002] The water pump and fan are driven by the prime mover such as the motor to rotate the impeller, which converts the mechanical energy of the prime mover into the kinetic energy and pressure energy of the fluid being conveyed. In the space coordinate system (R, φ, Z) that rotates synchronously with the impeller, any point in space can be determined by this coordinate system. The flow velocity W at any point can be expressed as the function W=f(R, φ, Z) of the point coordinates, which is the basic concept of ternary flow. Calculate the flow velocity W at any point in the flow channel in Figure (1), this is the ternary flow solution. Through the ternary flow calculation, the flow velocity at any point of the pump and fan can be obtained. The ternary flow design tec...
