Technology updates push gear pumps to intelligence

Gear pumps are rotary pumps that rely on the change and movement of the working volume formed between the pump cylinder and the meshing gear to transport liquid or increase its pressure. It consists of two gears, pump body and front and rear covers to form two closed spaces, when the gear rotates, the volume of the space on the gear disengagement side changes from small to large, forming a vacuum, sucking the liquid in, and the volume of the space on the gear meshing side changes from large to small, and the liquid is squeezed into the pipeline. The suction chamber and discharge chamber are separated by the meshing lines of the two gears. The pressure at the discharge outlet of a gear pump depends entirely on the resistance at the source of the pump.
In the next 10 years, the goal of the gear pump industry development plan is to improve the proportion of scientific research and development investment in the GDP of the pump manufacturing industry to more than 12%, and the contribution rate of the improvement of science and technology in the pump manufacturing industry will reach 78%, and promote the construction of the special-shaped pump manufacturing industry with modern equipment manufacturing as the core.
During the "Twelfth Five-Year Plan" period, the key research and technical reform projects of the gear pump industry are mainly reflected in two aspects:
On the one hand, the technical research of nuclear power hub equipment is mainly to carry out AP1000 nuclear main pump hub technology research; Research on the hub technology of the 1000 nuclear main pump of the second-generation plus technology, the research of the hub technology of the nuclear secondary and tertiary pumps, the research on the hub technology of the nuclear power pump of the million-kilowatt pressurized water reactor and the research on the technical scale of the nuclear power pump.
On the other hand, the technical research of petrochemical hub equipment includes the development of screw pumps, gear pumps, high-pressure small flow pumps, and quenching oil pump hub technology research for million-ton devices.
