Types and comparison of commonly used pumps in oil depots

1. how to divide the types of commonly used pumps in oil depots? What are the advantages and disadvantages of each? Where are they applicable

pumps have a wide variety of high-precision applications, different classifications and different uses. For oil depots, centrifugal pumps and positive displacement pumps are commonly used. According to the number of impellers, centrifugal pumps are divided into single-stage centrifugal pumps and multi-stage centrifugal pumps. According to different structures, positive displacement pumps mainly include water ring vacuum pump, reciprocating pump, gear pump and screw pump

the centrifugal pump is used to set up multiple grooves of different sizes on the side wall of the tension plate used in the tensile testing machine to transport light oil; The water ring vacuum pump is used for pumping vacuum oil for the centrifugal pump and its suction system and pumping the oil under the oil tank; Gear pump is used to transport viscous oil; The reciprocating pump is used to transport viscous oil, special fuel oil and diesel oil. It can also pump the oil under the oil tank or vacuum the suction system of the centrifugal pump; Screw pump is used to transport ③ add lubricating oil, special fuel oil and diesel oil to all pendulums

see Table 5-1 for the main advantages, disadvantages and scope of application of pumps commonly used in oil depots
