Embodiment Construction
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0032] The invention provides a vertical axial flow pump, the working principle of which is to realize the convenient installation and maintenance of the entire axial flow pump by using the separate installation of the elbow type pump body, the lower pump body, the pup joint and the pump shaft; After mixing PTFE resin and polyetheretherketone, the elbow pump body, the lower pump body, the pup joint and the pump shaft are made by molding process, so that the elbow type pump body, the lower pump body, the pup joint and the pump shaft are uniform It has the performance of 300° high temperature resistance, strong corrosion resistance and strong abrasion resistance, which is 140° higher than the existing technology, and prolongs the service life of the entire axial flow pump.

The invention discloses a vertical axial flow pump. The vertical axial flow pump comprises a bent type pump body and a pump shaft, the bottom end of the bent type pump body is connected with a lower pump body, the lower face of the lower pump body is connected with a short joint, the bottom end of the pump shaft penetrates the bent type pump body to be arranged at the bottom of the lower pump bodyand the short joint, an impeller is arranged at the bottom end of the pump shaft, the pump shaft, the lower pump body, the short joint and the bent type pump body are all formed in a manner that soluble polytetrafluoroethylene resin and polyether-ether-ketone are mixed and then subject to die pressing, and according to the component proportion of the soluble polytetrafluoroethylene resin and thepolyether-ether-ketone adopted by the pump shaft, the lower pump body, the short joint and the bent type pump body, the amount of the soluble polytetrafluoroethylene resin ranges from 30 to 70%, and the amount of the polyether-ether-ketone ranges from 30 to 70%%. Through separated mounting of the bent type pump body, the lower pump body, the short joint and the pump shaft, convenient mounting andmaintaining of the whole axial flow pump can be achieved. The the pump shaft, the lower pump body, the short joint and the bent type pump body are all formed in the manner that the soluble polytetrafluoroethylene resin and the polyether-ether-ketone are mixed and then subject to die pressing, the bent type pump body, the lower pump body, the short joint and the pump shaft has the properties of resisting high temperature of 300 DEG C, strong corrosion and strong wear, and the service life of the whole axial flow pump is prolonged.
Description
technical field [0001] The invention relates to an axial flow pump, in particular to a vertical axial flow pump utilizing ultra-high temperature resistance and strong abrasion resistance. Background technique [0002] In the existing technology, axial flow pumps are widely used in titanium dioxide industry, phosphating industry, disinfectant, fluorine silicon industry, special steel pickling, seawater treatment industry and other fields. , There are particles, high solid content concentration, and ultra-high temperature liquid transmission, which greatly reduces the service life of the axial flow pump. There are also some enterprises that use fluorine plastic spray lining inside the axial flow pump, but the fluorine material is not resistant to high temperature (maximum service temperature 160 ℃), and its wear resistance is very poor, so it cannot be used for a long time. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the pres...
