The forced circulation pump does not rely on the centrifugal force of the impeller to the liquid, but uses the thrust of the rotating impeller blades to make the sent liquid flow along the direction of the pump axis. When the pump shaft is driven by the motor to rotate, because the blade has a certain helix angle with the axis of the pump shaft, a thrust (or lift) is generated on the liquid, and the liquid is pushed out and discharged along the discharge pipe. When the liquid is pushed out, a partial vacuum is formed at the original position, and the liquid outside will be sucked into the impeller along the inlet pipe under the action of atmospheric pressure. As long as the impeller keeps rotating, the pump can continuously suck in and discharge liquid. The forced circulation pump works by using the horizontal thrust along the direction of the pump axis generated by the rotation of the impeller, so it is also called a horizontal axial flow pump. Mainly used in the evaporation of diaphragm method caustic soda, phosphoric acid, vacuum salt production, lactic acid, calcium lactate, alumina, titanium dioxide, calcium chloride, ammonium chloride, sodium chlorate, sugar, molten salt, paper, waste water and other industries. Concentration and cooling, in order to improve the production capacity of the equipment, increase the heat transfer coefficient of the heat exchanger for forced circulation. Therefore, it can also be called an axial flow evaporative circulation pump.

China and India are preparing to become partners in space research. The two countries have begun planning to build the largest astronomical telescope in the world in Hawaii in the United States in the next decade. As early as 2009, China became an observer of this project and India joined the following year. Now both countries have become partners in this project.
China and India will invest more than 100 million U.S. dollars each to build a telescope with a diameter of more than 30 meters on the Mauna Kea volcano in Hawaii. The two countries will also share the observation time. After the completion of the telescope will be the world's largest and most advanced telescope equipment, and it has become a landmark masterpiece of the two countries' space cooperation.
The telescope contains a 30-meter living mirror, nearly 100 feet in length, and more than all today's telescopes. Remote telescopes are very helpful for research. In the future, we can get a good understanding of the planet’s origins, black holes, and even dark matter and dark energy. China hopes to discover astronomy vigorously. If it is successfully built, China’s position in this area will steadily increase and it will also make a great contribution to the world.
