Fluoroplastic chemical pump is an energy-saving pump. The performance and requirements of the pump are designed according to the performance and size specified in the standard. The product layout is reasonable, the user selection range is wide, the maintenance is convenient, and the efficiency and suction power are at a high level. Corrosion resistant, high temperature resistance, can convey any corrosive media, such as concentrated acid, alkali, oxidizing agent, etc. No damage, high mechanical strength, small size, compact structure, easy to use and maintain, smooth flow path, high efficiency and energy saving. The main reason it can achieve this goal is that the material it uses is poly (perfluoroethylene propylene). Products made of this material have good corrosion resistance and rigidity, as well as excellent impact and twist resistance.
The pump housing of the fluoroplastic chemical pump is an energy conversion housing, which is affected by the pressure of the liquid and the temperature of the liquid. The cracks in the casing of fluoroplastic chemical pumps are usually caused by mechanical or thermal stress. Therefore, the pump casing should be checked regularly. The crack repair method and repair method of chemical pump are as follows:
(1) Crack inspection: Gently tap the shell with a hammer. If there is a cracking sound, it indicates that a rupture has occurred. Carefully look for crack locations in fluoroplastic chemical pumps. If necessary, it can be examined with a magnifying glass or colored flaw detection method, and the location and length of the crack can be determined.
(2) Crack repair method:
a. If the crack is located in a place where there is no pressure or no sealing effect, in order to prevent the crack from expanding, a round hole with a diameter of 3 mm can be drilled at the beginning and end of the crack to eliminate local stress concentration.
If the crack is in the area of compression, the repair method is as follows.
Before welding, drill a small hole at both ends of the crack, then shovel out the groove along the crack and install bolts on the groove to prevent nearby material from pulling apart as it cools and shrinks.
Fluoroplastic chemical pumps are widely used in industry, urban water supply, drainage, and can also be used for farmland, orchard drainage and irrigation, for the transportation of clean water or other liquids with physical and chemical properties similar to clear water. Fluoroplastic chemical pumps are widely used in corrosive media transportation, ion membrane caustic soda project chlorine water wastewater treatment and acidification process, non-ferrous metal smelting in the electrolyte transportation, automotive manufacturing pickling process, and pharmaceutical, petroleum, electroplating, dyes, pesticides, papermaking, food and other industries, in the temperature of -20 °C ~ 120 °C long-term transportation of any concentration of sulfuric acid, hydrofluoric acid, nitric acid, aqua regia, strong alkali, strong oxidant and other strong corrosive media without damage.
