Impeller positioning structure for vertical suspended semi submersible vertical turbine pump
The impeller positioning structure used in a vertical suspended semi submersible vertical turbine pump includes a pump shaft with an impeller connection section; Impeller, which has an impeller fixing seat; Positioning cone sleeve, located between the impeller fixing seat and the impeller connecting section; And, the connecting flange is fixedly combined with the first end of the positioning cone sleeve, and the connecting flange is axially opposite to the impeller fixing seat, and is also fixedly combined with the impeller fixing seat. The advantages of this technical method are: (1) eliminating the need for specialized disassembly and assembly tools - punching tubes, saving costs; (2) Reduced the difficulty of assembly and disassembly; (3) Can accurately and easily ensure the inlet section size of the impeller; (4) Being able to control the magnitude of the clamping force between the cone sleeve and the shaft, reducing the probability of the impeller falling off during operation.
Technical requirements: 1. An impeller positioning structure for a vertical suspended semi submersible vertical turbine pump, characterized by comprising a pump shaft with an impeller connection section, wherein the outer peripheral surface of the impeller connection section is a cylindrical surface; The impeller has an impeller fixing seat, which is arranged around the impeller connecting section, and the inner circumferential surface of the impeller fixing seat is a conical surface; A positioning cone sleeve is located between the impeller fixed seat and the impeller connecting section. The inner peripheral surface of the positioning cone sleeve is a cylindrical surface, and the inner peripheral surface of the positioning cone sleeve is in contact with the outer peripheral surface of the impeller connecting section. The outer peripheral surface of the positioning cone sleeve is a conical surface, and the outer peripheral surface of the positioning cone sleeve is in contact with the inner peripheral surface of the impeller fixed seat; And, a connecting flange is fixedly connected to the first end of the positioning cone sleeve, and the connecting flange is axially opposite to the impeller fixing seat. The connecting flange has a screw coupling hole, and the impeller fixing seat has a screw coupling hole. The first connecting piece is used to connect the screw coupling hole and the screw coupling hole, so that the connecting flange is also fixedly combined with the impeller fixing seat.
