Weld fluorine plastic centrifugal pump housing by lining the surface of the part to be a continuous weld and butt weld. You can not spot welding, intermittent welding. Shall not be used more riveting. Should be polished smooth weld, the weld seam projection height ≤0.5mm not have holes, undercuts, cracks and any other form of surface pores and lack of penetration defects. Unqualified, lined chemical pumps, can be repaired. After the patch should still meet the above requirements. By tests to determine the lining thickness δ≥2mm more appropriate. And with the increased diameter of the pump to increase the density of fluorine plastic should be used in about 2.16g / cm3, chemical pumps, and does not allow the presence of impurities in the raw materials. Lining material for food, medicine, sanitary valves, also non-toxic, sterile, no impurities clean material. Surface fluorine plastic valves should be smooth, without pores, cracks, inclusions and other defects. Flange at the flange and the other at the corner should be uniform color, no whitening phenomenon. Large-diameter welded steel fluorine plastic centrifugal pump can be way, fluorine plastic chemical pumps, welding point in line with GB / T150 standards. The internal shape of fluorine plastic centrifugal pump should be as simple, easy liner and mold making, chemical pump mechanical seal housing by lining should be smooth and should show all of the corner arc transition arc radius R≥2mm.
