The application scenarios of special working condition pumps mainly include the following:
- Petrochemical industry: In the petrochemical industry, special working condition pumps are used to transport high-temperature, high-pressure, and highly corrosive media, such as liquid hydrocarbons and their vapors. For example, Shanghai Qiaoxu's explosion-proof magnetic pumps perform well under high-temperature and high-pressure conditions and can withstand temperatures up to 400°C and pressures of 10Mpa.
- Coal chemical industry and other chemical industries: In these fields, special working condition pumps are used to handle various highly corrosive media, such as acid, alkali, and salt solutions. For example, high-silicon cast iron or fluoroplastic lining materials are usually used when transporting concentrated sulfuric acid, while Hastelloy or titanium alloy materials are used when transporting highly acidic media such as hydrochloric acid.
- Nonferrous smelting: In the nonferrous smelting process, special working condition pumps are used to transport high-temperature molten materials to ensure the continuity and safety of the smelting process.
- New energy solar thermal power generation: In the field of new energy solar thermal power generation, special working condition pumps are used to transport high-temperature and high-pressure working media to support the stable operation of power generation equipment.
- Thermal power and nuclear power: In the field of thermal power and nuclear power, special working condition pumps are used for high-pressure liquid transmission and cooling systems to ensure the normal operation of power generation equipment. For example, multistage centrifugal pumps are widely used in boiler feed water systems in thermal power generation.
- Offshore platform: On offshore platforms and ships, special working condition pumps are used to treat seawater and high-salinity media to ensure the corrosion resistance and stability of the equipment. Materials such as duplex stainless steel or super stainless steel are usually used.
- Environmental protection device: In environmental protection devices, special working condition pumps are used to treat various industrial wastewaters and high-viscosity media to ensure the smooth progress of the environmental protection treatment process.
These application scenarios require special working condition pumps to be highly professional and unique, and to be able to adapt to extreme or special working conditions, such as high temperature, high pressure, strong corrosion, high viscosity, containing solid particles, and flammable and explosive complex situations.
