Fluoroplastic alloy to enhance corrosion resistant pump disassembly sequence

Fluoroplastic alloy to enhance corrosion resistant pump is over-current part material selection is of strong resistance to corrosion of fluorine plastic fluorine alloy: fep ( F46） And polytetrafluoroethylene ( F4) Chemical centrifugal pump made of, can transport any strong corrosive medium, suitable for conveying any concentration of sulfuric acid, hydrochloric acid, acetic acid, hydrofluoric acid, nitric acid and aqua regia, strong alkali, strong oxidizing agents, organic solvents, reductant and other harsh conditions of strong corrosive medium, is currently one of the strongest corrosion resistant equipment in the world.

fluoroplastic alloy to enhance corrosion resistant pump disassembly sequence is as follows:

1, close the import and export the valve, loosen bolts in motor, the fluorine plastic alloy reinforced corrosion resistant pump pumps and pump head ( The motor coupling and pump coupling) To separate. and motor connection with claw type shaft coupling, first remove the loose bracket and four connecting bolts of base, make the pump and motor release.

2, remove the protective cover, loosen the bracket and the pump body connection bolt, suspension bracket, with wooden handle release tap on pump body, impeller, pump cover can be, bracket, bearing box, mechanical seal, apart from the pump body.

3, loosen the fluoroplastic alloy pump pump shaft side fastening nut, with copper bar tap nut and tighten bolts, coccygeal vertebra of the impeller and the pump shaft taper sleeve on separate, impeller, pump cover, mechanical seal, support, bearing housing, their separation.

4, loosen the mechanical seal ring of the two fastening screws, mallet tap even the axis machine center bolt, can step down from the impeller shaft mechanical seal ring, and then remove the fluoroplastic alloy to enhance corrosion resistant pump cover, pump discharge pump mechanical seal gland screws on the cover, can be removed from the pump cover the static ring of the mechanical seal.

5, if you want to change the fluoroplastic alloy to enhance corrosion resistant pump body, water pump to remove the inlet and outlet pipe connection bolt and pump body at the bottom of the bolt.

6, loosen the water pump shaft gland screw around. shaft, bearing, washing oil chamber.

7, replacing the impeller, to remove round nut on the coccygeal vertebra.
