It is available to carry out numerical simulation and fluid dynamic analysis further. Based on Frozen-Rotor Approach and Rotor-Stator Approach, the numerical simulation was carried out in the centrifugal pump and the numerical results showed that the flow in the impeller and volute of centrifugal pump is periodically unsteady. Due to the interaction between impeller and volute the flow is characterized by pressure fluctuations and it is the strongest at impeller outlet and at the vicinity of the tongue. The unsteady pressure fluctuations are also one of the most important reasons to induce vibration and noise. Secondly, the flow field of the volute is characteristic of the vortex flow, and the vortex flow presents very complicated developing process which is creating, increasing and dissipating every now and then. All these lead to very large flow loss in the volute.
采用Frozen-Rotor冻结转子模式和Rotor-Stator滑移界面模式系统开展了不同工况下离心泵内叶轮与蜗壳耦合的定常和非定常流动研究,结果表明由于叶轮与蜗壳的干扰蜗壳进口周向流动的不均匀性是非常强烈的,特别是叶轮与蜗舌间的相互干扰最为强烈,一直影响到叶轮进口和蜗壳扩散管出口的流场;在蜗壳内整个流动是以旋涡形式向出口推进的,并随着包角的变化旋涡表现出十分复杂的产生、发展和耗散的演化过程,导致蜗壳内较大的流动损失。

Zhang Min:"TrumpJet" technology sets the dosing point of wet end chemical additives at the outlet pipe of machine screen of the head-box, and uses Booster pump to extract stock as dilution media, and uses "TrumpJet" mixing to inject chemical additives into Headbox loop, which dexterously uses energy of stock in Headbox pipelines, making a very low power consumption in Booster pump (only requires the energy of speeding up for chemical additives flow), eliminating large volume of chemical additives for fresh water dilution, and chemical additives and stock can be fully mixed within 2 seconds, and delivered to model for shaping at the maximum of chemical additives efficiency.
在数千年的造纸发展史上,传统的湿部化学品的加入和混合一直是利用加后稀释水的方法通过静态在线混合器来完成的,由于湿部化学品的加入量很小,,其流量仅为 0.1~1升/秒甚至更小,而要将如此之小的流量加入到纸机流浆箱300 ~2000 升/秒的工艺系统浆料流体中,同时达到化学品与造纸纤维均匀接触,即使是消耗大量的清水和使用在线混合器也很难达到&完全&且&有效&地混合,于是就又产生了将化学品的加入点,提前到远离流浆箱的工艺位置,这样可以延长混合时间,但人们忽略了在过早加入化学品的同时也带来了化学品的流失、化学品在短循环系统循环产生有害副产物生成浆管悬挂、化学品水解失效等一系列弊病。
