Novel wing type efficient centrifugal impeller

Abstract

The invention discloses a novel wing type efficient centrifugal impeller which comprises an impeller main plate, an impeller side plate and blades, the front face of the impeller main plate is fixedly connected with the back face of the impeller side plate, the multiple blades are fixedly installed on the front face of the impeller side plate, and the torsional angle of each blade is 40-50 degrees. According to the novel wing type efficient centrifugal impeller, wear-resistant protection on the blades can be achieved by coating the surfaces of the blades with protective coatings, and meanwhile the purposes that the friction factor of the coatings is greatly reduced by applying paraffin components in the coatings, so that the adhesive force of the surfaces of the blades is reduced are well achieved; according to the centrifugal impeller, the protection effect of the centrifugal impeller is greatly improved, the situation that the surfaces of the blades are prone to being scratched by solid particles in air in the long-term use process, and consequently the surfaces of the blades are rusted and corroded is well avoided, the service life of the blades is greatly prolonged, and the blades are easier to clean.

Description

technical field [0001] The invention relates to the technical field of impellers, in particular to a novel wing-type high-efficiency centrifugal impeller. Background technique [0002] The centrifugal wind wheel refers to the wind wheel that enters the wind in the axial direction and leaves the wind in the radial direction, and uses the centrifugal force (depending on the speed and outer diameter) to do work to increase the pressure of the air. The wind wheel of the centrifugal fan can be divided into forward-leaning wind wheel, According to the blade angle of the impeller, the centrifugal impeller can be divided into three types: forward-inclined, radial and backward-inclined. According to the structure of the impeller, the impeller can be divided into multi-wing type. There are two types of impeller and sub-wheel. According to the installation requirements of the motor, it can be divided into outer rotor impeller and inner rotor impeller. Forward-inclined impeller means th...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a novel wing-type high-efficiency centrifugal impeller, which solves the problem that the existing centrifugal impeller has poor protection effect, and the surface of the blade is easily scratched by solid particles in the air during long-term use. damage, which leads to rust and corrosion on the surface of the blade, which greatly reduces the service life of the blade. At the same time, the surface of the existing blade will be covered with a lot of dust during long-term use, which is difficult to clean. Protective coatings are used to protect the blades against wear, but at the same time, the friction coefficient of the coating is greatly reduced by applying the paraffin wax component in the coating to reduce the adhesion of the blade surface.
