[0002] The wear-resistant defect of fluoroplastics can be effectively solved by coating a layer of wear-resistant material on the surface of fluoroplastics. However, the strength of the fluoro lining layer is not as high as that of metal parts. At the same time, the thermal expansion and melting coefficients of metal parts and non-metallic fluoro materials are different, so they are prone to deformation, cracking and falling off during use.

[0003] A shell clamp type waste acid concentrating pump is proposed in the patent with publication number CN102345609A, which includes a shell clamp, a front pump cover, a pump shell, a metal insert, a shaft sleeve A, a shaft sleeve B, a rear pump cover, a pump frame, and a through hole.

Suction phenomenon, greatly improving the strength of the overall pump, the shell clamp is one of two, three or four split structures, which is convenient for the installation and processing of the shell clamp, the shaft sleeve is composed of two sections, the contact with the seal is made of silicon carbide material, and the other section is molded by PFA soluble tetrafluoroethylene or FEP polyperfluoroethylene propylene material, which ensures the strength of the seal contact and the shaft sleeve in contact with the flowing liquid has sufficient corrosion resistance. A metal insert is provided on the rear pump cover, and a number of evenly distributed through holes are provided on the metal insert, which ensures the connection strength of the fluoroplastic layer, prevents the fluoroplastic layer and the metal insert from peeling off, and ensures the strength of the rear pump cover at the same time.
