Technological Reform Pushes Gear Pumps to Intelligence

The gear pump is composed of two gears, a pump body and a front cover and a back cover. The gear pump is a rotary pump that transfers liquid or pressurizes by changing and moving the working volume formed between the pump cylinder and the meshing gear. When the gear rotates, the volume of the space on the disengagement side of the gear becomes smaller, a vacuum is formed, the liquid is sucked, the volume of the space on the side of the gear engagement side is reduced from large, and the liquid is pushed into the pipeline. The suction chamber and the discharge chamber are separated by the meshing lines of the two gears. The pressure at the outlet of the gear pump depends entirely on the resistance of the pump outlet.

During the “Twelfth Five-Year Plan” period, key projects in the gear pump industry and technological reform projects are mainly reflected in three aspects:

On the one hand, the technical research of nuclear power plant equipment is mainly focused on the research of ap1000 nuclear main pump hub technology; the research of the second generation plus technology 1000 nuclear main pump hub technology; the research of nuclear two-stage and nuclear three-stage pump hub technology; and millions of kilowatts Research on the Hub Technology of Pumps for Nuclear Power Nuclear Pumps and the Research of Nuclear Power Pump Technology Scale .

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 quench oil pump hub technology for the 1 million-ton pta plant; the third aspect is the development of energy-saving mechanisms for pump products. the study.

In the next five years, the goal of the development plan of the gear pump industry is that the proportion of research and development investment in the GDP of the water pump manufacturing industry will increase to more than 6%, the contribution rate of the water pump manufacturing technology will increase by 68%, and the development of the modern equipment manufacturing industry will be promoted. Water pump manufacturing.
