Description

Technical Field

[0001] The utility model relates to the technical field of fluid delivery pumps, in particular to a Tesla pump. Background Art

[0002] In the prior art, water pumps are generally divided into volumetric water pumps and vane water pumps. When the above two types of water pumps convey some corrosive, highly viscous, highly shear-sensitive fluid materials, the fluid has a certain viscosity, which will reduce the fluid conveying efficiency. As the working time increases, the body is seriously worn and prone to blockage. In addition, the vane water pump is assembled in different positions. When the vane water pump is immersed below the water surface, the residual air in the impeller chamber cannot be discharged from the vane water pump, causing the vane water pump to fail to operate normally in some cases, that is, the "cavitation" phenomenon. Later, a hole was drilled in the upper part of the impeller chamber to achieve the purpose of discharging the residual air in the impeller chamber. However, when the vane water pump is running, water will spray out through the exhaust hole, reducing the operating performance of the vane water pump. In the process of liquid transmission, the volumetric pump has a high output pulse, which leads to unstable liquid delivery and high noise during operation.

[0003] The Chinese utility model patent with application number: 201721779542.9 discloses an anti-cavitation water pump, which relates to the field of fluid conveying equipment. It includes a pump body, an inlet pipe, an outlet pipe and an impeller, the inlet pipe and the outlet pipe are respectively connected to the pump body, the impeller is located in the pump body, a pressure controller and a filter are arranged on the inlet pipe, the pressure controller is provided with a metal coating on the inner arc surface of the pump body at one end away from the pump body, and the impeller includes a plurality of blades evenly distributed along the circumferential direction, and a metal baffle is arranged on the inner side of each blade. However, although this anti-cavitation water pump can avoid the influence of the "cavitation" phenomenon, when it is used to transport corrosive, highly viscous, and highly shear-sensitive fluid media, the fluid viscosity will reduce its conveying efficiency, and when it is used to transport corrosive, highly viscous, and highly shear-sensitive fluids, its pump body is severely worn and easily blocked.
