概述
SAKZ 系列纸浆泵是根据我公司三十多年的制泵经验,详细研究并吸收国内外厂家纸浆泵的优点,结合国内造纸行业纸浆泵的实际使用情况,自主研制、开发的新一代纸浆泵。
引进国内外最优秀水力模型,采用 CFD 计算流体动力学分析方法,针对性地进行优化分析改进,性能指标全面超越行业水平,达到国际先进水平,最高效率突破 92%。
采用三片、四片或六片敞开式大扭曲叶片,适当的加宽流道,通过能力更强,适用于输送各种不同的介质——从水到滤液,纸浆到回收纤维以及浓度高达 6% 的机浆纤维,从水到过滤器叶轮,泵到回收纤维和机械浆料。在添加剂,也可适用于企业制糖、淀粉加工、化工液体等介质的输送。
根据国内纸浆粗、杂质大、要求耐磨等特点,经过电脑模拟实验,在叶轮后盖板处加了三角形盖板,使泵既有自行轴向推力补偿能力,又很好的耐磨性,易于维修。
叶轮前后均设耐磨板,可有效保护泵体和泵盖。
采用单级单吸悬臂结构,泵的进出口与轴在同一垂直平面,泵体上单独铸出支撑脚,直接固定在底座上,泵盖通过螺栓固定在泵体和轴承架之间,在检修时拆除轴承架与泵体之间的连接螺栓,就可以在不拆卸泵体、出口管路情况下,叶轮、后耐磨板、轴封部件和轴承架等可作为“提拉部件”进行拆卸或安装。
对大规格的泵,在泵和电机之间加上中间加长联轴器,这样在检修时只要撤除中间联轴器,就可以把传动部分从泵体中拿出,同时也不必移动电机。
旋转方向:从驱动端看,泵的旋转方向为顺时针旋转。
GENERAL
SAKZ series pulp pump is new generation of product researched and developed independently by our company on the basis of over 30 years of pump manufacturing experience, introducing and absorbing advantages of pulp pump pumps at home and abroad as well as consideration of actual operations of pulp pumping of paper making at home.
It introduces the internationally most excellent hydraulic model, adopts CFD flow mechanical analysis, conducts special optimization and improvement, and the performance indices achieved a good jump, reaching internationally advanced level, and the max efficiency exceeds 92%.
It adopts three, four or six opening highly twisted blades, properly widen flow pass with high throughput capacity, which is applicable for conveying various media, from water to filter liquor, pulp to recycled fiber and mechanical pulp with thickness of 6%, in addition, it is applicable for conveyings media such as sugar making, starch process and chemical liquids.
According to the environments such as coarse pulp, big impurity and high wear resistance, through computer-based simulation tests, a triangular cover plate is designed on the back cover plate of impeller, which makes the pump have axial thrust compensation, high wear resistance and easy for maintenance.
Wear-resisting plates are designed before and after the impeller to well protect the pump body and cover.
It adopts one-stage and one suction cantilever construction, the pump inlet and outlet is kept on the same vertical plane, supporting legs are welded on the pump body to be fixed on the base, the pump cover is fixed between the pump and the bearing seat through bolts. In case of examination or repair, remove the connecting bolts between the bearing seat and the pump body, as such, without removing the inlet and outlet pipes of the pump, the impeller, back wear-resisting plate, shaft seal and bearing support can be taken as a pull/draw part for removal and installation.
As for high-specification pump, a prolonged shaft coupling can be added between the pump and the motor, as such, after the shaft coupling is removed before examination and repair, the driving part can be taken out of the pump body without removal of the motor.
Rotation direction: seen from the driving, the pump's rotation direction shall be clockwise.
