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.

The movie "To Youth": Youth is a strong attitude of nostalgia and faith

Youth needs strong nostalgia and refuses to screw
In a recent interview, Zhao Wei said that the maturity of her mind is a process from softness to strength. When people have experienced the friction of life, the emotions that are easily evoked when they are young are no longer so easy to emerge. The heart becomes strong and even hard. Zhao Wei also said bluntly that he does not like this kind of hard.
Although the entire film began with nostalgia, it was not artificial or screwed. It was even a bit naked to show a past that included almost everyone. The cassette tape recorder, the canteen's iron lunch box, the banned induction cookers, the playground's constant ringing basketball sounds, each element can implicate different pictures and stories, and each spectator also recalls these old objects in the surroundings. From youth. There is a kind of introspection from the back to the front in this reality, behind which is a direct, non-bending power.
It does not give us time to be embellished, but also refuses to screw it. Youth is sometimes the case. When we have not yet had time to taste, we have already gone from being cheap to extravagant and passing away in the wind.
We can easily compare the “Creation to Youth†and the “Little New Year†as a representative of the fresh atmosphere. Although they are all youth themes, they have met society from the campus. In fact, it is not the kind of greenery that is revealed in the film. Beautiful, but a kind of helplessness in the wandering turmoil. This cannot be attributed to the gender gap between a female director and a male director. There is no good or bad here, but there is only wind. Chen Xiaozheng and Shen Jiayi, the protagonists of the two films, share the same rationality. The other protagonist, Zheng Wei and Ke Jingteng invariably took on the emotional role. The impact of this kind of values ​​will naturally bring the contradictions to the film. When we face such a situation, how to choose it is a resonance for a generation or even everyone.
Youth tamed everyone with a gap and shock. This is also a must for all youth movies. It is a major issue. We are very pleased to see that Zhao Wei has not shot a movie about youth, nostalgia, and love in Taiwan's artistic literature. Perhaps that style is not the bone of the Little Swallow in our minds.
