Novel high-temperature high-pressure wear-resistant double-volute centrifugal pump

The invention belongs to the technical field of double-volute centrifugal pumps, and particularly relates to a novel high-temperature high-pressure wear-resistant double-volute centrifugal pump. The double-volute centrifugal pump comprises an outer pump shell, wherein an inner shell is arranged on the inner side of the outer pump shell, an impeller is arranged on the inner side, far away from theouter pump shell, of the inner shell, a protection plate is arranged on the side, far away from the inner shell, of the impeller, and a pump cover is arranged on the side, far away from the impeller,of the protection plate. According to the double-volute centrifugal pump, a dual shell design is adopted by the shell design, so that the double-volute centrifugal pump is suitable for conveying medium with high temperature, high pressure and strong corrosion resistance, the outer pump shell is used as a main bearing part and is used for separating from the inner shell, so that the inner shell bearing medium has corrosion
