进口多级切割泵哪家品牌好

进口多级切割泵Product Description: It includes a pump body and a base. A water inlet is arranged in the base, a water outlet is arranged on one side of the pump body, a motor-driven rotating shaft is arranged in the pump body, the rotating shaft successively passes through the shaft holes of the impeller, the cutting disc and the cutting knife, the inlet end of the impeller is provided with an impeller knife edge, the top of the blade of the impeller is provided with a blade knife edge, which is an inclined plane and matches with the inclined plane of the pump body in the pump body, The upper cutting edge and lower cutting edge with radial sawtooth shape are evenly arranged on the cutting disc. 进口多级切割泵The number of upper cutting edge is more than that of lower cutting edge. The lower cutting edge and cutting edge form the first level cutting structure, the upper cutting edge and impeller edge form the second level cutting structure, and the blade edge and the inclined plane of pump body form the third level cutting structure. characteristic: 进口多级切割泵The technical scheme of two-stage cutting submersible cutting sewage pump is as follows: a high-efficiency large flow channel semi open impeller with rear cover plate is arranged at the lower center of the pump body; A 30-45 ° large inclination guiding design is adopted between the rear cover plate and the front cover plate of the inlet side of the high-efficiency large flow channel semi open impeller blade, and the center line of the outlet flow channel of the impeller blade is aligned with the radial outlet center line of the pump body at the same height; The lower end face of the pump body is connected with the pump base; The upper part of the pump base is connected with an axially adjustable cutting disc, which is located at the lower part of the impeller in the pump body. 进口多级切割泵The profile shape of the upper end of the cutting disc is completely consistent with the shape of the flow surface of the front cover plate projected by the axial surface of the impeller blade, and the required gap of 0.2 ~ 0.3mm can be formed between the upper end of the cutting disc and the flow surface of the front cover plate of the impeller blade by adjusting the axial displacement of the cutting disc. Principle: Flat square grooves are symmetrically arranged on both sides of the bottom of the rotating shaft. The upper end of the flat square groove is flush with the lower cutting edge of the cutting disc. The cutting knife is installed on the flat square groove and axially fixed by bolts with flat washers and spring washers. After installation, the cutting knife presses the shaft sleeve and the shaft sleeve presses the impeller, that is, the bolts fix the cutting knife, shaft sleeve and impeller axially at the same time.
