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 rotational moulding pump body of a magnetic pump. The rotational moulding pump body comprises a shell (1) and a lining layer (2) attached to the inner wall of the shell (1); and the shell (1) and the lining layer (2) are connected by adopting a structure (3) for preventing the lining from stripping and dropping. The rotational moulding pump body disclosed by the invention is simple in structure and easy to install, and the lining and the pump body are adhered firmly.

Description

Technical field [0001] The invention involves an electromagnetic pump, which specializes in a magnetic pump roller pump body. Background technique [0002] The corrosion -resistant plastic magnetic pump has been widely used for the conveyor of chemical medium that is strongly corroded with strong acids, strong alkali, organic solvents and other chemical media. The lining of the pump of the magnetic pump is the key part of the magnetic pump.The key to pump quality. [0003] like figure 1 A traditional magnetic pump roller pump body, the pump body uses ETFE as the lining raw material, but because the pump importer is generally in the studioThe molding bonding is integrated. Due to the penetration of the corrosive media, there is a certain corrosion of the lining surface of the pump body. For a period of time, the lining and the metal pump shell are ticked off. For example, figure 2 It shows that the lining is drumped under the action of negative pressure, rubbing with the high -spe...
