The requirements for the development of agricultural pumps are to improve efficiency, reduce energy consumption, and make full use of natural energy. Use a large pump instead of multiple small pumps to improve the efficiency of the unit, save materials, reduce energy consumption and engineering costs, and facilitate automated management. Therefore, a variety of large -scale stream pumps and mixed flow pumps have developed rapidly. The maximum diameter of the impeller reaches 4.6 meters and 6.2 meters, respectively, and the supporting power is up to 12,500 kilowatts. trend. In terms of water lifting water, it mainly develops submersible pumps. Its maximum caliber has reached 1 meter. Water wheel pumps, wind tie rod pumps, screw pumps, diaphragm pumps, piston pumps and water pumps dedicated to the same spray irrigation equipment in China and other countries are also valued to varying degrees in China and other countries.

Energy -saving and emission reduction has now become the primary content of China's economic development outline.  Special high energy reduction policies have been proposed to high energy, steel, non -ferrous, petrochemical, and water disposal. As a fluid transportation equipment for industrial center, the water pump occupies the primary of energy consumption, and it has become the first question to be disposed of in energy conservation operations.

The most commonly used driving method of water pump is driven by motor. The energy -saving method of the pump is mainly to operate the pump unit (pump, original motivation, and transition) at the highest power, which reduces the power in the outside world to the lowest point. The energy conservation of pumps makes comprehensive skills, which touches the energy saving of the pump itself, the energy saving of the system, and the operation operation of the operation.

The energy saving meaning of the pump is serious: Pumps are large power consumption. According to the Calculation of the General Machinery Industry Association, the pump power consumption accounts for about 20%of the national power generation. The pump power promotion is serious about energy saving and emission reduction.

Article 4 of the State Council's "Regulations on Property Management" "The state encourages the adoption of new technologies and methods to rely on scientific and technological progress to improve the level of property management and service." Dynamic saving has always been one of the key operations of property equipment management. The continuous promotion of China's urbanization, and more and more high -level communities and properties. The high -efficiency energy -saving water pumps that ensure the energy saving rate in the mall have become a hot product.
