Chemical pump classification: (1) In accordance with the working principle, structure classification 1) vane pump: through the pump shaft rotation impetus to a variety of impeller blades to centrifugal force or axial force, the liquid to the pipeline or container, such as centrifugal pumps, vortex Pump, mixed flow pump, axial flow pump. 2) positive displacement pump: the use of continuous changes in the volume of the pump cylinder liquid delivery pump, such as reciprocating pump, piston pump, gear pump, screw pump. 3) Other types of pumps: Electromagnetic pumps that use electromagnetic to deliver liquid electrical conductors; Pumps that use fluid energy to deliver liquids, such as jet pumps, air boosters, etc. (2) Classification according to chemical industry 1) Process flow pump: including feed pump, return pump, circulating pump, flushing pump, sewage pump, replenishment pump, output pump and so on. 2) Utility Pump: Including boiler pump, cooling tower pump, fire pump, water pump with deep well. 3) Auxiliary use pump: Including lubricating oil pump, seal pump, hydraulic pump and so on. 4) pipeline pump: pipeline pump, loading and unloading pump and so on. (3) According to the transmission medium classification 1) Pump: Including water pump, boiler feed pump, condensate pump, hot water pump. 2) Corrosion-resistant pump: Including stainless steel pump, high silicon cast iron pump, ceramic acid pump, impermeable graphite pump, hard rubber pump, hard polyvinyl chloride pump, shield pump, diaphragm pump, titanium pump and so on. 3) Impurity pump: Including slurry pump, sand pump, sewage pump, pulverized coal pump, ash pump and so on. 4) oil pump: cold oil pump, hot oil pump, oil pump, liquid hydrocarbon pump. (4) Classification according to the conditions of use 1) Large flow and micro-flow pump: the flow rates are respectively 300m3 / min and 0.01L / min; 2) High temperature pump and low temperature pump: High pressure pump and low pressure pump: high pressure up to 200MPa, vacuum degree is 2.66 --- 10.66kPa (20-80mmHg); 4) high speed pump and low speed pump: high speed up to 24000r / min, low speed 5-10r / min; Metering pump: flow measurement accuracy of ± 0.3%; 6) high viscosity pump: Viscosity up to several thousand Pa (Pa · s). Chemical pump uses: chemical pump for bottles, barrels, cylinders, pools or other containers to extract corrosive liquids. Chemical pumps are widely used in chemical, petroleum, metallurgy, light industry, synthetic fiber, environmental protection, food, medicine and other departments. Chemical pump with stable and reliable performance, good sealing performance, handsome in appearance, easy to use maintenance and so on. To improve product quality, reduce run, run, drip, drain, prevent pollution, improve the environment, play a big role. Chemical pump for chemical, petroleum, metallurgy, power plants, food, pharmaceuticals, synthetic fibers and other departments transport temperature in various corrosive media or physical and chemical properties of high-quality media.
