Abstract

The invention belongs to a split type high silicon-iron alloy acid-proof axial flow pump, which comprises a shaft (12), wherein the right end of the shaft (12) is fixedly provided with a transmission wheel (16). The pump is characterized in that the shaft (12) is arranged between a front bearing (11) and a back bearing (14), the left end of the front bearing (11) is provided with a front bearing cover (20), the left end of the bearing (12) is provided with a sealing shaft sleeve (8), the left side of the sealing shaft sleeve (8) is provided with a protecting sleeve (7), the left side of the protecting sleeve (7) is provided with an impeller (6), the left side of the impeller (6) is connected with the left end of the shaft (12) through threads by an impeller nut (5), the outer side of the impeller (6) is provided with a lengthening section (1), the outer side of the lengthening section (1) is provided with a lengthening sleeve (2), the lengthening sleeve (2) is connected with a pump jacket (3) through a bolt (21), the pump jacket (3) is arranged on a pump body (4), and the right end of the pump jacket (3) is connected with a bearing box body (13) through the bolt (21). The pump has the advantages that the temperature-resistant and acid corrosion-resistant properties are high, and the solid corrosion-resistant property is high; the use and installation of outer lining steel jacket are safe and reliable, the fault rate is low, and the service life is long.

Description

technical field [0001] The invention belongs to pumps, in particular to a shell-type high-silicon-iron alloy acid-resistant axial-flow pump. Background technique [0002] There are many types of pumps and a wide range of applications. At present, the pumps used in the titanium dioxide industry generally have poor high temperature resistance, poor corrosion resistance, and poor solid abrasion resistance, which brings some unsafe factors to the installation in terms of structure. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a sandwich-type high-silicon ferroalloy acid-resistant axial-flow pump with high temperature resistance, strong corrosion resistance, good solid abrasion resistance, and safe and reliable installation. [0004] The technical solution adopted by the present invention to solve the technical problem is: a shell-type high-silicon ferroalloy acid-resistant axial-f...
