The flow paths of fluids are often precisely regulated by pumps. Whether it's transporting corrosive media in a chemical workshop or maintaining water circulation in building pipelines, pumps are always the core hubs for fluid control. Due to the diversity in working principles, structural forms, and application scenarios, pumps have formed a rich system of types. Clearly understanding these classifications and their advantages enables us to find the most suitable fluid transportation solutions under different working conditions.
Centrifugal pumps are one of the most widely used types of pumps. They generate centrifugal force through a high - speed rotating impeller, which throws out the fluid inside the pump, thus achieving fluid transportation. Centrifugal pumps have the advantages of large flow rate, simple structure, easy operation, and convenient maintenance. In chemical production, centrifugal pumps are often used to transport various corrosive or non - corrosive liquids. In water supply and drainage systems, they can efficiently supply water to cities and drain sewage. In the petroleum industry, centrifugal pumps can be used in the transportation and refining processes of crude oil.
Positive - displacement pumps transport liquids by relying on the change of the working volume inside the pump cylinder. Common positive - displacement pumps include gear pumps, screw pumps, and piston pumps. Gear pumps change the volume of the pump chamber through the meshing and separation of gears to transport liquids. They have strong self - priming ability, uniform flow rate, and are effective in transporting high - viscosity liquids. They are often used to transport viscous liquids such as lubricating oil and ink. Screw pumps use the meshing of screws to form a sealed space for liquid transportation. They operate smoothly, with low noise and high efficiency, and are suitable for transporting high - viscosity media and liquids containing solid particles. They are widely used in industries such as sewage treatment and food processing. Piston pumps change the working volume through the reciprocating motion of the piston in the cylinder to transport liquids. They have high output pressure and convenient flow rate adjustment and play an important role in fields such as high - pressure cleaning and petrochemical industry.
Vane pumps transport liquids by changing the working volume through the sliding of vanes in the rotor slots. Vane pumps have the advantages of uniform flow rate, smooth operation, low noise, and high efficiency. They are often applied in fields such as the hydraulic systems of machine tools, hydraulic transmissions of ships, and aerospace, providing stable hydraulic power for the systems.
In addition to the common types mentioned above, there are also pumps such as jet pumps. Jet pumps use the energy of high - speed fluids to suck and transport liquids. They have a simple structure and no moving parts, and are suitable for some special occasions, such as vacuum pumping and bilge drainage of ships. Pneumatic diaphragm pumps are powered by compressed air. They have strong corrosion resistance, strong self - priming ability, and can operate under no - load conditions. In industries such as chemical engineering, electroplating, and environmental protection, they are used to transport highly corrosive, high - viscosity, volatile liquids and liquids containing particles.
