进口混流泵/Mixed flow pump/德国品质
德国KAYSEN凯森进口混流泵概述
原动机带动叶轮旋转后，对液体的作用既有离心力又有轴向推力，是离心泵和轴流泵的综合，液体斜向流出叶轮。因此它是介于离心泵和轴流泵之间的一种泵。混流泵的比转速高于离心泵，低于轴流泵，一般在300-500之间。它的扬程比轴流泵高，但流量比轴流泵小，比离心泵大。用于输送清洁和污染的介质，化学中性或侵蚀性的介质，还有化工流程中强制循环、海水养殖、城市煤气工程、水处理系统。
主要特点：
混流泵是一种“拉出”式结构泵，在检查和拆卸叶轮和轴封时，毋须将与泵体相连接的管路拆开。装有精密加工的泵轴和装有稀油润滑的轴承，在填料函盖中装有防护轴套。轴承箱的油位，可由恒位油杯来控制。
泵体的支脚，可承受来自管路的任何载荷，并直接传递给基础。这样，转子不会因为泵承受受载荷而产生弯曲，从而保证轴承的***佳使用寿命。
由于较大的过流面积，从而减少阻塞。
泵的旋转方向，从驱动端看，为顺时针方向。
动力驱动可采用电动机或内燃机。
泵装置上可以配备完整的放气装置，有利于吸入管路的排气。
轴封
填料密封或双端面机械密封。

Germany KAYSEN imported mixed flow pump overview
After the prime mover drives the impeller to rotate, the action on the liquid has both centrifugal force and axial thrust. It is a combination of the centrifugal pump and the axial flow pump, and the liquid flows obliquely out of the impeller. It is therefore a pump between the centrifugal pump and the axial pump. The specific speed of the mixed flow pump is higher than that of the centrifugal pump, which is lower than the axial flow pump, generally between 300 and 500. Its head is higher than the axial pump, but the flow is ***aller than the axial pump and larger than the centrifugal pump. Used to transport clean and contaminated media, chemically neutral or aggressive media, as well as forced circulation, marine aquaculture, urban gas engineering, and water treatment systems in chemical processes.
main feature:
The mixed flow pump is a "pull out" type structure pump, and it is not necessary to disassemble the pipe connected to the pump body when inspecting and disassembling the impeller and the shaft seal. It is equipped with a precision machined pump shaft and a bearing with a thin oil lubrication. A protective bushing is installed in the stuffing box cover. The oil level of the bearing housing can be controlled by the c***tant oil cup.
The feet of the pump body can withstand any load from the pipeline and pass directly to the foundation. In this way, the rotor does not bend due to the load on the pump, thus ensuring the optimum service life of the bearing.
Reduces blockage due to the large flow area.
The direction of rotation of the pump, viewed from the drive end, is clockwise.
The power drive can be an electric motor or an internal combustion engine.
The pump unit can be equipped with a complete deflation device to facilitate the exhaust of the suction line.
Shaft seal
Packing seal or double mechanical seal.
Material
Corrosion resistant material.
The main advantage:
●The flow cross section is large and it is not easy to block
●Strong structure and long life
●High pump efficiency and low energy c***umption
●The pump has uniform energy c***umption over the entire performance range, can be started under the closed valve, and the motor is not overloaded
main application:
●Marine culture
● Deliver clean and contaminated media
●City gas engineering
●Water treatment system
● Forced circulation in chemical processes
●Chemical neutral or aggressive media
