Machining equipment used for impeller with super-hydrophobic surface and impeller manufactured by machining equipment

Abstract

The invention discloses machining equipment used for an impeller with the super-hydrophobic surface and the impeller manufactured by the machining equipment. The machining equipment comprises a fixingsupport used for clamping the impeller, driving equipment used for driving the impeller to rotate, laser etching equipment used for machining the super-hydrophobic surface on the surface of the impeller, a dust suction device used for sucking dust particles, and a controller used for controlling the whole machining process. The driving equipment is mounted on the fixing support; the laser etchingequipment is mounted on the driving equipment; a dust suction opening of the dust suction device is aligned with a working area of the fixing support; and the control end of the driving equipment, the control end of the laser etching equipment and the control end of the dust suction device are electrically connected with corresponding pins of the controller. The impeller comprises an impeller body. The impeller body comprises an impeller front cover plate, an impeller rear cover plate and a plurality of impeller blades. A plurality of grooves used for improving the surface lubricating characteristic of the impeller blades are etched in the surfaces of the impeller blades. The machining equipment has the beneficial effects that manual disturbance is avoided, detaching is convenient, and the viscous resistance and hydraulic loss of the impeller are reduced.

Description

technical field [0001] The invention relates to a processing device for a superhydrophobic surface impeller and the impeller. Background technique [0002] The impeller is the core part of the centrifugal pump. The blades on the impeller act on the fluid. In the traditional process, the inner and outer surfaces of the impeller are required to be smooth to reduce the friction loss of the water flow. The latest theory confirms that the non-smooth surface can change the streamline of the fluid on the solid surface, such as forming a secondary vortex, changing the quasi-order structure of the turbulent flow, and achieving vibration and drag reduction. Therefore, applying the non-smooth surface to the impeller of the pump has good economic value and research significance. [0003] Many special occasions also require pumps to pump liquids. Many industries, such as corrosive medium transportation in chemical production, chlorine water wastewater treatment and acid addition process...
