      As the heart of the device, the pump is used extensively in the petroleum and chemical industries. According to the data, in the petrochemical equipment, the electromechanical power allocated to the pump accounts for 26% to 59% of the total power consumption of the plant. According to experts' estimates, the average power consumption of global pump products accounts for about 20% of the country's total electricity. In other words, in the petrochemical industry, the proportion of electricity used by pumps is 1.3 to 3 times the average. For example, a large 10 million tons/year of oil refining and its supporting devices (atmospheric and vacuum distillation, catalytic cracking, coking, hydrogenation, etc.) require about 200 types of pumps, of which centrifugal pumps account for 83%, reciprocating pumps account for 6%, gear pumps and screw pumps account for 3%, and other 8%. A million tons/year of ethylene and its supporting devices (including ethylene, butadiene, gasoline hydrogenation, polyethylene, polypropylene, acrylic, styrene and polystyrene, irrigation areas, public works, etc.) need about 1,000 types of pumps, of which centrifugal pumps (including non-sealed centrifugal pumps) account for 82%, reciprocating pumps and metering pumps account for 8%, gear pumps and screw pumps account for 5%. The other 5%.
