[0034] The technical solutions of the present invention will be described in more detail below in conjunction with embodiments:
[0035] Such as figure 1 , 2 , 3 and 4: The present invention includes a composite impeller rotor, a pump housing 20, a pump inlet part 19, a pump outlet part 21 and a pump rear cover 18, the pump inlet part 19, the pump outlet part 21, the pump rear The cover plate 18 is installed on the pump housing 20 and encloses to form a pump cavity for accommodating the composite impeller rotor. The inner side of the pump cavity formed by the pump housing 20, the pump inlet portion 19, the pump outlet portion 21 and the pump rear cover plate 18 are all provided with a non-metallic lining (ultra-high molecular weight polyethylene). The pump cavity is wear-resistant and corrosion-resistant, is more suitable for conveying belt granular media, and is easy to install and disassemble the composite impeller rotor.
[0036] The composite impeller rotor includes an impelle...
