Slurry pump sheath convenient to replace

Abstract

The invention belongs to the field of slurry pumps, and particularly relates to a slurry pump jacket convenient to replace, which comprises a first pump shell and a second pump shell, the first pump shell and the second pump shell are fixedly connected through bolts and nuts, and the inner walls of the first pump shell and the second pump shell are respectively provided with a first jacket body and a second jacket body; the back face of the first sheath body and the back face of the second sheath body are connected with a connecting rod. The first electromagnet can generate suction force on the first magnet block, and the second electromagnet can generate suction force on the second magnet block, so that the first sheath body and the second sheath body are tensioned after being mounted, and the tensioning degree is adjusted along with the working power of the slurry pump, so that the connection tightness is effectively ensured, and the service life of the slurry pump is prolonged. And meanwhile, when disassembly is needed, reverse current is introduced into the first electromagnet and the second electromagnet, so that repulsive force is generated, and then the first sheath body and the second sheath body can be rapidly separated from the first pump shell and the second pump shell.

Description

technical field [0001] The invention relates to the field of slurry pumps, in particular to a slurry pump sheath that can be easily replaced. Background technique [0002] Slurry pumps can be widely used in mines, electric power, metallurgy, coal, environmental protection and other industries to transport slurry containing abrasive solid particles. Such as slurry transportation in metallurgical beneficiation plants, hydraulic ash removal in thermal power plants, coal slurry and heavy medium transportation in coal washing plants, dredging of rivers, dredging of rivers, etc. In the chemical industry, some corrosive slurries containing crystals can also be transported. [0003] During the actual use of existing slurry pumps, in order to avoid the impact and corrosion of the slurry slag on the inner wall of the pump casing, a sheath is installed inside the pump casing.

Problems solved by technology

[0003] During the actual use of existing slurry pumps, in order to avoid the impact and corrosion of the slurry slag on the inner wall of the pump casing, a sheath is installed inside the pump casing. Most of the existing slurry pump jackets are bolted It is fixed on the inner wall of the pump casing, but for a long time, the sheath will still be corroded and damaged by impact, so it needs to be replaced, but the fixed bolts are prone to corrosion due to the influence of slurry, which makes disassembly troublesome, and the sheath It is impossible to know whether it is damaged, so that the replacement of the sheath is not timely, which makes the pump casing vulnerable to corrosion and impact.
