4个不同的管中泵叶轮可以输送什么介质？
目前，管中泵叶轮有四种基本型式：流道式（单流道、双流道）、叶片式（闭式、开式）、螺旋离心式和旋流式。下面详细介绍各种叶轮的性能和结构。管中泵的泵叶轮通常为闭式叶轮。转轮是从入口到出口的弯曲通道。这种叶轮适用于输送含有大颗粒或长纤维的液体。因为这种叶轮具有优良的抗堵塞性能。但其缺点是抗汽蚀性能比其它形式弱。叶片叶轮中的半开式叶轮和开式叶轮便于铸造、维护和清理输送过程中堵塞的杂质。但其缺点是在输送过程中固体颗粒的冲蚀作用下，压水室壁面与叶片之间的间隙增大，降低了管中泵在管道中的运行效率。由于间隙的增大，破坏了通道内液体流型的稳定性，管内泵发生振动。这种叶轮不易输送含有大颗粒和长纤维的介质。闭式叶轮效率高，能长时间平稳运行。VAREM管中泵在管道中轴向推力小，但封闭式叶轮容易缠绕，不易输送含有大颗粒或长纤维的污水介质。WATERSUNNY管中泵的螺旋离心叶轮是一种扭曲叶片，从锥形毂体上的吸入口轴向伸出。当输送的液体流过叶片时，不会撞击到管中泵的任何部位，因此不会损坏管中泵，也不会损坏输送的液体。由于螺杆的推进作用，悬浮颗粒的通过能力强，因此这种叶轮在管中泵适用于输送含有大颗粒和长纤维的介质。旋流叶轮旋流叶轮是将叶轮的全部或部分缩进流道内的压力室，具有良好的抗堵塞性能。水压室内的颗粒流是由叶轮旋转产生的涡流驱动的。悬浮颗粒的运动不产生能量，能量在流道中与液体交换。在流动过程中，悬浮颗粒或长纤维不与磨损的叶片接触，叶片磨损轻，不因磨损而产生间隙增大，适用于含有大颗粒和长纤维的介质的泵送。上海龙亚管中泵服务承诺：产品在保修期内，对有缺陷的产品负责维修、更换、退货；所有质量投诉，24小时内回复。未经故障排除或结论性意见，不得将外派服务人员撤离现场。本厂配件为原装配件。上海龙亚泵阀生产的管中泵产品及配件与原型号通用，配套齐全。如果安装尺寸和质量有问题，我们将无条件退货和更换，所有设备将终身使用！（除易损件外，整机保修一年）。售后部门联系方式：4OO-001-5655。
What kind of medium can four different pump impellers transport?
At present, there are four basic types of impeller in pipe pump: channel type (single channel, double channel), blade type (closed type, open type), spiral centrifugal type and swirl type. The performance and structure of various impellers are described in detail below. The impeller of pump in pipe is usually closed impeller. The runner is a curved passage from the entrance to the exit. The impeller is suitable for conveying liquid containing large particles or long fibers. Because the impeller has excellent anti clogging performance. But its disadvantage is that its anti cavitation performance is weaker than other forms. The semi open impeller and open impeller in the blade impeller are convenient for casting, maintenance and cleaning up the impurities blocked in the conveying process. But its disadvantage is that under the erosion of solid particles in the transportation process, the gap between the wall of the pressure chamber and the blade increases, which reduces the operation efficiency of the pump in the pipeline. Due to the increase of the gap, the stability of the liquid flow pattern in the channel is destroyed, and the pump in the pipe vibrates. This impeller is not easy to transport medium containing large particles and long fibers. The closed impeller has high efficiency and can run smoothly for a long time. The axial thrust of the pump in the varem pipe is small, but the closed impeller is easy to wind, so it is not easy to transport the sewage medium containing large particles or long fibers. The spiral centrifugal impeller of watersunny tube pump is a kind of twisted blade, which extends axially from the suction port on the conical hub body. When the delivered liquid flows through the blades, it will not hit any part of the pump in the pipe, so it will not damage the pump in the pipe, and it will not damage the delivered liquid. Due to the propulsion of screw and strong passing capacity of suspended particles, the impeller in pipe pump is suitable for conveying medium containing large particles and long fibers. Swirl impeller is a kind of pressure chamber which retracts all or part of the impeller into the flow channel, and has good anti clogging performance. The particle flow in the water pressure chamber is driven by the vortex generated by the rotation of the impeller. The movement of suspended particles does not produce energy, and the energy is exchanged with the liquid in the flow channel. In the flow process, the suspended particles or long fibers do not contact with the worn blade, the blade wear is light, and the gap does not increase due to the wear. It is suitable for the pumping of medium containing large particles and long fibers.
