Classification of chemical pumps according to different cond
Classification of chemical pumps according to different conditions
1. According to the working principle and structure of chemical pumps
1) Vane pump: When the pump shaft rotates, various impeller blades are driven to give the liquid centrifugal force or axial force, and transport the liquid to the pipeline or container, such as centrifugal pump, vortex pump, mixed flow pump, and axial flow pump.
2) Positive displacement pumps: pumps that use continuous changes in the volume of the pump cylinder to deliver liquids, such as reciprocating pumps, piston pumps, gear pumps, and screw pumps.
3) Other forms of pumps: there are electromagnetic pumps that use electromagnetism to transport liquid electrical conductors; pumps that use fluid energy to transport liquids, such as jet pumps, air lifts, etc.
2. Classification according to the production process of chemical pumps
1) Process pumps: including feed pumps, reflux pumps, circulating pumps, flushing pumps, sewage pumps, supplementary pumps, output pumps, etc.
2) Public works pumps: including boiler pumps, cooling tower pumps, fire pumps, deep well pumps for water sources, etc.
3) Pumps for auxiliary purposes: including lubricating oil pumps, sealed oil pumps, pumps for hydraulic transmission, etc.
4) Pipeline transfer pumps: pumps for oil pipelines, pumps for loading and unloading vehicles, etc.
3. Classification by pumped liquid
1) Water pumps: including clean water pumps, boiler feed water 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, hard rubber lined pumps, rigid PVC pumps, canned motor pumps, diaphragm pumps, titanium pumps, etc.
3) Impurity pumps: including slurry pumps, sand pumps, sewage pumps, pulverized coal pumps, ash pumps, etc.
4) Oil pump: cold oil pump, hot oil pump, oil slurry pump, liquid hydrocarbon pump, etc.
Fourth, classified according to the use conditions of chemical pumps
1) Large flow and micro flow pumps: flow rates are 300m3/min and 0.01L/min respectively;
2) High temperature pump and low temperature pump: high temperature reaches 500℃, low temperature reaches Z53℃;
3) High-pressure pump and low-pressure pump: high pressure up to 200MPa, vacuum degree 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;
5) Accurate metering pump: The metering accuracy of the flow rate reaches ±0.3%;
6) High-viscosity pump: the viscosity reaches several kilopascal seconds (Pa?s).
5. Chemical pump usage: Chemical pumps are suitable for pumping corrosive liquids from bottles, barrels, cylinders, pools or other containers.
Chemical pumps are widely used in chemical, petroleum, metallurgy, light industry, synthetic fiber, environmental protection, food, medicine and other sectors. The chemical pump has the advantages of stable and reliable performance, good sealing performance, beautiful appearance, convenient use and maintenance, etc. In order to improve product quality, reduce running, spilling, dripping and leakage, prevent pollution, and improve the environment, it plays a great role.
Chemical pumps are suitable for transporting corrosive media at various degrees Celsius or media with high physical and chemical properties in chemical, petroleum, metallurgical, power station, food, pharmaceutical, synthetic fiber and other sectors.
Chemical pump products mainly include: various glass fiber chemical pumps, corrosion resistant plastic pumps, high temperature chemical pumps, standard chemical process pumps, magnetic drive pumps, etc.
Chemical pumps are used for pumping clean water, containing abrasive, harmful substances to ordinary pump body materials, suspended, non-explosive substances that are corrosive to stainless steel materials;
Chemical pumps are also widely used for water supply; for heating, air conditioning, cooling and circulation systems; for civil and industrial purposes; for fire fighting; for irrigation; for daily use and civil, industrial, horticultural, and irrigation purposes; Used in rainwater storage projects; used in occasions where low noise is required; used in pressurization, suitable for transporting corrosive, explosive, and particulate water or liquid; suitable for pressurization of pipe networks.
