Application of electrostatic paint coating for pump subassembly of hot water submersible pump

Geothermal well _ hot springs use hot water submersible pump to enhance the water, then most of the water quality of hot water wells have different degrees of corrosive and a small amount of sediment; simply spray paint in the unit table, and can not effectively prevent the pump body Corrosion of wear-resistant materials, the unit cost is relatively high, stainless steel material _ duplex steel _ copper material for hot water wells to enhance the application of water is not a lot, mainly should be For the price of the problem.
Now to share with you the Shanghai Wei Shanghai pump pump components introduced electrostatic coating the advantages of coating treatment:
① excellent chemical resistance.
② excellent corrosion resistance:
Electrostatic paint coating can withstand sewage and a variety of water treatment agents (some of which will also produce corrosion of stainless steel)
● Concentrated brine.
● Sewage: urea, ammonia, hydrocarbons, sodium acetate, fatty acid Moet.
● eliminate agent: nitrogen, nitrogen, ozone.
● oxidant: oxygen, from potassium permanganate.
● flocculants and softeners: ferric chloride, aluminum chloride, sulfate.
③ excellent wear resistance.
④ excellent impact resistance.
⑤ excellent resistance to bending.
⑥ excellent weathering performance.
⑦ excellent resistance to cavitation performance.
⑧ excellent edge of the enclosed performance.
Electrostatic paint coating processing advantages:
● easy to control powder adhesion;
● can achieve partial coating;
- the coating can be melted in an oven at a lower temperature and for a shorter period of time than the preheating step of the fluidized bed;
• No cross-linking risk compared to thermosetting materials;
● the required amount of powder is small;
● Coating automation can be achieved.
 Electrostatic paint coating treatment is mainly used in hot water submersible pump body: the fluid flow shell on the impeller, the effective avoid some unnecessary wear and tear corrosion agent. Several years of application by the customer's unanimous approval
