        Chemical pump classification

        Date:2019-03-15 Author: Click:

        According to the different chemical pump materials, its application field is classified as follows

        1) chemical pump (stainless steel) is widely used in petroleum, chemical, metallurgy, synthetic fiber, pharmaceutical, food, synthetic fiber and other departments for conveying alkaline corrosive medium;

        2) chemical pump (fluoroplastic material) is used for conveying any acidic or alkaline corrosive medium;

        3) chemical pump (cast iron material) is used for industrial, urban water supply, drainage, can also be used for farmland, orchard irrigation, for conveying water or physical and chemical properties similar to water and other liquids.

        Chemical pumps are classified according to their USES

        1) process pump: including feed pump, reflux pump, circulation pump, flushing pump, sewage pump, supplementary pump, output pump, etc.

        2) public engineering pump: including boiler pump, cooling tower pump, fire pump, deep well pump, etc.

        3) auxiliary pump: including lubricating oil pump, sealing oil pump, hydraulic transmission pump, etc.

        4) pipeline pump: pump for oil pipeline, pump for loading and unloading vehicles, etc.

        Classification according to working principle and structure

        1) vane pump: when rotating through the pump shaft, drive various impeller blades to give liquid centrifugal force or axial force, and transfer liquid to pipes or containers, such as centrifugal pump, vortex pump, mixed flow pump and axial flow pump.

        2) positive displacement pump: it is a pump that USES the continuous change of the volume of the pump cylinder body to transfer liquid, such as reciprocating pump, piston pump, gear pump and screw pump.

        3) other types of pumps: electromagnetic pumps with liquid conductance using electromagnetic transport;A pump that USES fluid energy to move liquids, such as a jet pump, an air lift, etc.

        Classification by delivery medium

        1) water pump: including fresh water pump, boiler feed water pump, condensate water pump and heat water pump.

        2) corrosion resistant pump: including stainless steel pump, high silicon cast iron pump, ceramic acid resistant pump, impervious graphite pump, hard rubber lined pump, hard PVC pump, shielding pump, diaphragm pump, titanium pump, etc.

        3) impurity pump: including slurry pump, sand pump, sewage pump, pulverized coal pump, ash pump, etc.

        4) oil pump: cold oil pump, hot oil pump, submerged oil pump, slurry pump, liquid hydrocarbon pump, etc.

        Classified by conditions of use

        1) high flow and low flow pump: the flow is 300m horses3 respectively;/ min and 0. O1L/min;

        2) high temperature and low temperature pump: high temperature of 500 ℃, low temperature to a Z53 ℃;

        3) high pressure pump and low pressure pump: high pressure up to 200MPa, the vacuum 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;

        5) accurate metering pump: the flow measurement accuracy is up to 0. 3%;

        6) high viscosity pump: viscosity up to thousands of parsecs (Pa·s).
