The chemical pump is an energy-saving pump jointly designed nationwide. The performance and technical requirements of the pump are designed according to the performance and dimensions specified in the international standard ISO2858.
The advantages of chemical pumps include a reasonable layout of water conservancy performance across the entire series, a wide range of user choices, a "rear open" structure, convenient maintenance, and an internationally advanced efficiency and suction head.
Classification of chemical pumps: stainless steel chemical pumps, plastic chemical pumps, fluoroplastic chemical pumps, electric chemical pumps, pneumatic chemical pumps.
Widely used in industry, urban water supply, drainage, and can also be used for irrigation and drainage in farmland and orchards, for transporting clean water or other liquids with physical and chemical properties similar to clean water.
According to the different materials of chemical pumps, their application fields are classified as follows:
1) Chemical pumps (made of stainless steel material) are widely used in industries such as petroleum, chemical, metallurgy, synthetic fibers, pharmaceuticals, food, and synthetic fibers to transport alkaline corrosive media;
2) Chemical pumps (made of fluoroplastic materials) are used to transport any acidic, alkaline or corrosive medium;
3) Chemical pumps (made of cast iron material) are used for industrial and urban water supply and drainage, as well as for irrigation and drainage in farmland and orchards. They are used to transport clean water or other liquids with physical and chemical properties similar to clean water.
According to the different uses of chemical pumps, provide a detailed introduction to their classification:
1) Process pumps: including feed pumps, reflux pumps, circulation pumps, flushing pumps, sewage pumps, makeup pumps, output pumps, etc.
2) Public works pumps: including boiler pumps, cooling tower pumps, fire pumps, deep well pumps for water sources, etc.
3) Auxiliary pumps: including lubricating oil pumps, sealing oil pumps, hydraulic transmission pumps, etc.
4) Pipeline delivery pump: pump for oil pipelines, pump for loading and unloading vehicles, etc.
Classified by working principle and structure:
1) Vane pump: When the pump shaft rotates, it drives various impeller blades to apply centrifugal or axial force to the liquid, conveying it to pipelines or containers, such as centrifugal pumps, vortex pumps, mixed flow pumps, and axial flow pumps.
2) Positive displacement pump: A pump that uses the continuous change in volume inside the pump cylinder to transport liquids, such as reciprocating pumps, piston pumps, gear pumps, and screw pumps.
3) Other forms of pumps: there are electromagnetic pumps that use electromagnetic transport to transport liquid conductive states; Pumps that use fluid energy to transport liquids, such as jet pumps, air elevators, etc.
Classified by conveying medium:
1) Water pumps: including clean water pumps, boiler feedwater pumps, condensate pumps, and hot water pumps.
2) Corrosion resistant pumps: including stainless steel pumps, high silicon cast iron pumps, ceramic acid resistant pumps, impermeable graphite pumps, lined hard rubber pumps, rigid polyvinyl chloride pumps, shielded pumps, diaphragm pumps, titanium pumps, etc.
3) Impurity pumps: including slurry pumps, sand pumps, sewage pumps, coal powder pumps, ash pumps, etc.
4) Oil pumps: cold oil pump, hot oil pump, submersible pump, slurry pump, liquid hydrocarbon pump, etc.
Classified by usage conditions:
1) High flow and low flow pumps: flow rates of 300m respectively/ Min and 0.1L/min;
2) High temperature pump and low temperature pump: high temperature up to 500 ℃, low temperature up to - Z53 ℃;
3) High pressure pump and low pressure pump: The high pressure reaches 200MPa, and the vacuum degree is 2.66-10.66kPa (20-80mmHg);
4) High speed pump and low-speed pump: up to 24000r/min at high speed and 5-10r/min at low speed;
5) Accurate metering pump: The flow measurement accuracy reaches ± 0 3%;
6) High viscosity pump: viscosity reaches several thousand pascals per second (Pa · s).
