Abstract
The present application relates to a kind of press equipment for vortex pump impeller, including fixing device and press device, fixing device includes fixed seat, two clamping components and clamping telescopic rod, two clamping components are installed in the top of fixed seat, and there is pump shaft placement cavity for placing pump shaft between two clamping components;Press device includes press seat and press component, press seat is located in the top of fixed seat, and is connected with fixed seat by clamping telescopic rod, press seat is set with press hole in the top of pump shaft, and the fixed end of press component is installed on press seat, the output end of press component is located in the top of press hole and is used to act impeller, press component is used to press impeller on pump shaft after passing through press hole;Wherein, clamping telescopic rod is linked with two clamping components, when clamping telescopic rod is contracted, two clamping components are close to each other and clamping fixed pump shaft;When clamping telescopic rod is lengthened, two clamping components are away from each other and loosen pump shaft.The above technical scheme is provided with the press equipment specially used for vortex pump impeller press, and pump shaft is positioned by fixing device.Afterwards, impeller can be placed directly behind pump shaft, and impeller is pressed on pump shaft by the press device set in the top of fixing device.Specifically, press component is used to press impeller on pump shaft through press hole, and press is completed.Pump shaft is positioned by fixing device, so that press position does not change, press is more accurate, then, uniform stress is provided to impeller by press component, avoid impeller damage, while improving press effect and press efficiency.
