Problems solved by technology

[0003] like figure 1 A traditional magnetic pump rotomolding pump body is shown, the pump body uses ETFE as the lining material, but because the inlet part of the pump body is generally in a negative pressure state in the working room, the lining layer and the metal pump casing are passed through rotomolding at the initial stage of use. Formed and bonded as a whole, due to the penetration of corrosive media, there is a certain amount of corrosion on the inner lining of the pump body. After a period of use, the lining and the inner surface of the metal pump casing peel off, such as figure 2 As shown, under the action of negative pressure, the lining bulges and rubs against the high-speed rotating impeller, the lining is quickly worn by the impeller, the lining is completely invalid, and the consequences of burning the impeller

Embodiment 1

[0026] A magnetic pump rotomoulding pump body, comprising a shell 1 and a liner 2 attached to the inner wall of the shell 1, the shell 1 and the liner 2 are connected by an anti-lining peel-off structure 3, so that the liner Layer 2 is firmly attached to the inner wall of the metal pump, preventing the lining layer 2 from bulging under the action of negative pressure.

Embodiment 2

[0028] A magnetic pump rotomoulding pump body, comprising a shell 1 and a liner 2 attached to the inner wall of the shell 1, the shell 1 and the liner 2 are connected by an anti-lining peel-off structure 3, and at the same time, each Ten permeation balance holes 4 are uniformly arranged on the shell 1 of square centimeters. If the medium can leak, it can also seep out of the housing 1 under the action of the penetration balance hole 4, and under the action of the anti-lining peel-off structure 3 and the penetration balance hole 4, the liner 2 is better prevented from falling off and bulging.

Embodiment 3

[0030] A magnetic pump rotomoulding pump body, comprising a shell 1 and a liner 2 attached to the inner wall of the shell 1, the shell 1 and the liner 2 are connected by an anti-lining peel-off structure 3, this embodiment The peeling off structure 3 of the middle defense lining is a dovetail groove structure, such as Figure 4 As shown, the dovetail groove structure can make the liner 2 and the shell 1 fit better, and the liner 2 can be easily installed on the shell 1 to facilitate the disassembly of the liner 2 .

Abstract

The invention discloses a rotomoulding pump body of a magnetic pump, which comprises a shell (1) and a liner (2) attached to the inner wall of the shell (1), the shell (1) and the liner (2) They are connected by an anti-lining peeling-off structure (3). The invention provides a rotationally molded pump body of a magnetic pump with simple structure, easy installation, and firm bonding of the liner and the pump body.

Description

technical field [0001] The invention relates to an electromagnetic pump, in particular to a rotationally molded pump body of a magnetic force pump. Background technique [0002] Corrosion-resistant plastic magnetic pumps have been widely used in the transportation of strong acids, strong alkalis, organic solvents and other chemical media that are highly corrosive and require no leakage. Key to pump quality. [0003] like figure 1 A traditional magnetic pump rotomolding pump body is shown, the pump body uses ETFE as the lining material, but because the inlet part of the pump body is generally in a negative pressure state in the working room, the lining layer and the metal pump casing are passed through rotomolding at the initial stage of use. Formed and bonded as a whole, due to the penetration of corrosive media, there is a certain amount of corrosion on the inner lining of the pump body. After a period of use, the lining and the inner surface of the metal pump casing peel...
