Processing device and processing method of simulated groove in inner wall of conical water inlet pipe of water pump

Abstract

The invention discloses a processing device and a processing method of a simulated groove in the inner wall of a conical water inlet pipe of a water pump. The processing device comprises a supportingmechanism, a processing mechanism, a rotating mechanism and a feeding machine, wherein the supporting mechanism is arranged at the outer part of the rotating mechanism; an output end of the rotating mechanism is connected with one end of the processing mechanism; the other end of the processing mechanism is connected with an action end of the feeding mechanism; one end of the supporting mechanismis defined as a front part, and one end of the feeding mechanism is defined as a rear part. The processing method comprises the following steps: fixing well a pipeline requiring to be processed, and regulating the feeding mechanism until a cutting tool assembly arrives a to-be-processed position; regulating the shape of a supporting frame, and enabling the supporting frame to press the inner wallof the pipeline; regulating a cutting blade of a cutting tool to be in contact with the inner wall of a to-be-processed pipeline; starting a rotating part, and starting to process a groove in the inner wall of the pipeline; repeating the operation, thus realizing continuous processing of the simulated groove in the to-be-processed pipeline. The processing device and the processing method, disclosed by the invention, have the beneficial effects that an application range is extremely wide, and the processing device and the processing method are not influenced by the size of a pipe wall; a self-locking function is obtained, and the accuracy is higher; the processing quality is high.

Description

technical field [0001] The invention relates to a processing device and a processing method for bionic grooves on the inner wall of a conical water inlet pipe of a water pump. Background technique [0002] As the world's energy crisis is aggravating day by day, the issue of energy saving is imminent. One of the main energy-saving means at this stage is to reduce the friction loss in the transportation process. According to the survey, in the long-distance pipeline transportation process, almost all the energy provided by the pump station is used to overcome the surface friction resistance. In most areas of the surface of these pipes, the flow is in a turbulent state, so research on how to reduce drag in turbulent flow is the primary task at this stage. [0003] Among the current turbulent drag reduction methods, the grooved surface drag reduction technology is recognized as the most promising due to its remarkable drag reduction effect and ease of popularization and use. ...
