How 泥浆泵 Work
利用旋转动能转化为流体流动的流体动力能, centrifugal 泥浆泵 motivate fluid flow along pipelines. 泵旋转, and thus rotational energy, 通常是由电动马达通过v形皮带驱动泵轴产生的. The fluid enters axially into the eye of the Pump impeller, which by its rotation acts tangentially and radially on the fluid. 流体通过叶轮获得速度和压力而加速, flowing radially outward into the casing, decelerating but building pressure. Being pressurized, it then exits the volute. 泵扬程中被排出的流体被作用于泵内流体的大气压力和静压所取代, pushing it into the impeller.
泵的转速由变速器的比例调节, 在某些情况下, 使用变频驱动器来调整更精确的工作速度. 需要注意的是不要使用高的关断比，这会导致功率损失. Head or more specifically total dynamic head, which is the sum of static, friction and pressure heads, is used to find the speed head. Calculated water head is corrected (HR)，使用被泵送的颗粒的d50，即固体体积百分比. 马力是按做功计算的，因此包括流体比重. 应始终参考制造商的曲线，以确保泵在最有效的区域运行.
It should be noted that this design of Pump, unlike a self-priming positive displa水泥 Pump, does not actually suck the fluid into the casing. 如上所述, 流体根据大气压力和容器内流体的高度(14)流入泵.5psi或33.5ft.hd. [10mhd] + the height to water level in the Sump).
Other factors affect the performance of the Pump, most important of which is the Net Positive Suction Head (汽蚀余量), which is not only an equipment issue but a system issue. 汽蚀余量A is a measure of how close to vapor pressure the fluid becomes. 汽蚀余量R 为了防止流体空化，是否需要在吸力侧设置水头值. Heated solutions are particularly prone. 当泵发生空化时，叶轮和轴承可能发生严重损坏.
离心泵的反向作用是作为水轮机将水压势能转化为机械转动能. 这方面的例子是将尾矿沿长斜坡排入池塘. Special builds are required.
衬里材料各不相同，通常根据要处理的材料和存在的化学物质来选择. Most sand sized materials <5mm (4mesh) can be handled effectively by the use of the high-quality natural rubber compound liners. 砾石应由硬质金属泵处理，如Ni-Hard或Hi-Chrome (27%).
为什么菠菜网最稳定正规平台_最全菠菜网大全 泥浆泵
菠菜网最稳定正规平台_最全菠菜网大全泥浆泵采用分离式套管设计，可以轻松进入尾管, the impeller and the gland for maintenance. 大多数泥浆泵都有一个总成辅助臂，用于在叶轮更换和压盖维护期间支撑吸入套管. 该功能允许技术人员将套管从泵上移开，而不是将组件掉落到地面或使用起重机.
菠菜网最稳定正规平台_最全菠菜网大全泥浆泵具有现场可更换的湿端衬套，便于维护. These liners are self-gasketing to provide a reliable seal. 几种橡胶化合物可用于各种用途:高耐磨性的天然橡胶混合物和不同化学成分的丁腈.
菠菜网最稳定正规平台_最全菠菜网大全的轴承总成非常简单，但却经久耐用. Unlike other manufacturers, 轴承座重组过程不需要预加载设置给定的湿端, heavy-duty roller bearing and the drive-end, 双, 调心, spherical roller bearing. Fit the components into the housing per the Installation, Operation and Maintenance Manual, lubricate as instructed and you are ready to go. 工厂重建轴承组件可用于最紧急的维护.
Types of 泥浆泵 Glands
Three styles of gland are available with 菠菜网最稳定正规平台_最全菠菜网大全 泥浆泵:
- d型 压盖是我们最适合的压盖，具有旋转橡胶密封圈和静态陶瓷表面. 这两种高度耐磨的部件经过调整，使最少量的浆液可以在表面之间通过，起到润滑作用. This gland design absorbs little energy and requires no external lubrication; although 在某些情况下 it can be fitted with flushing water. 这种设计非常适用于没有清洁工艺用水或不希望泵送的泥浆稀释的应用场合. This design is not recommended for more viscous types of slurry.
- 屏蔽 阀盖的维护需求最低，但需要在高于泵排出压力(0.2-1 m3/hr at 20-25 kPa above). 这种压盖的特点是两个橡胶密封件，在加压水注入处由一个灯笼环隔开. 调整外部密封，使压盖水渗出润滑, 当内部密封处的水将固体从密封处冲走时. This gland is ideal for applications such as Thickener underflow.
- p型 腺体是经典的设计，在行业中是最常见的. 专门的填料环包裹在压盖套筒周围，通过压缩形成密封. 这种压盖需要外部水源来润滑填料，并且会将少量工艺用水泄漏到大气中. Clean water is most critical to this gland, 虽然在某些情况下，润滑脂润滑的压盖可以提供与烃类相容的衬套和组件.
每个压盖都设计用于密封泵的加压湿端，使其与大气隔绝. All glands have a gland sleeve to protect the shaft from abrasion. 密封件和部件由耐磨/耐腐蚀材料制造.
Types of 泥浆泵 Impellers
菠菜网最稳定正规平台_最全菠菜网大全提供两种叶轮设计:封闭叶片和开放叶片.
封闭的叶片 impellers are molded from high quality rubber over a steel skeleton. 与开放式叶片相比，它可以在更长的时间内保持效率，并且不需要额外的维护来调整吸入衬管界面的间隙. 典型的开式叶轮在磨损时允许显著的旁路，效率显著降低.
开放的叶片 impellers are not a recessed impeller style Pump. 它们是标准的泵头与旋涡流设计叶轮，推动流体通过和出套管. 开式叶片是固体和纤维材料的选择，堵塞的风险最小, 例如，在农业应用中，将肥料从层沙中分离出来.
Frequently Asked Questions About 泥浆泵
向专家请教Apart from the usual guarding of rotating components, it is important to get advice from the manufacturer or their dealer. 如果你买的是二手泵，这一点尤其正确——仅仅因为说明书上说它是为泵2设计的,000流量, 如果关税与最初的关税不一样，它可能不会达到接近的水平. Each duty is very specific. Let’s say you installed the Pump and had the wrong size pipe, you could have a critical issue with material settling out, which may even cause the Pump to explode.
矿山安全与健康管理局(2009年公报)报告了这一现象，认为这是一个重大问题. 浆料泵进水管和出水管堵塞, 据估计，电机40%的能量将用于加热泵的湿端内容物. 热量上升很快，蒸汽压力会增加，爆炸就会发生. 确认正确的流速以保持物料悬浮，并保持设计的固体百分比和粒度可以降低这种风险. 还建议安装互锁和/或报警的电力和压力监测传感器. 菠菜网最稳定正规平台_最全菠菜网大全最近开发的热电偶装置在安装和报警时是另一个安全功能.
良好的工艺设计, proper mechanical design of sumps and piping, 以及安全相关附件的使用是决定泵安全运行的因素. The manufacturer is always the best place to start.
因为泵以固定速度运行，并且没有被告知你移走了一段管道, it will keep spinning away but now finds it is easier to pump. If you look at your pump curve, 你会看到，如果你降低水头(阻力)，泵正在抽水, 新的工作点将向右移动，速度曲线和水头将在更高的流量下相交. 更高的流量意味着更多的工作被完成，因此电力需求更大. It would be the same if you reduced the height you are pumping to. 如果通过增加排放点的管道或垂直高度来增加水头，则会发生相反的情况. 增加水头而不改变速度的危险是导致较低的流量, which may be below the critical setting velocity. 如果您正在考虑更改泵系统的任何部分，请联系制造商.
菠菜网最稳定正规平台_最全菠菜网大全的轴承组件是围绕使用油脂润滑而设计的-这意味着所使用的密封件不适合油. 油的设计更为复杂，由于缺乏润滑和溢出，任何泄漏都要麻烦得多. 润滑脂润滑简化了维护，适用于这类设备中常见的rpm
Rather than just say no, which would be the first reaction from any Pump manufacturer, let’s examine why you probably don’t want to consider this. 从我们的角度来看，90%的问题是在泵的吸入侧. 这些问题, 90% of those are associated with poor sump design, such as wrong wall angles (buildup in valley angles and corners), too shallow (vortexing), too big (settling and sloughing), too small (air entrainment, vortexing) and incorrect suction line (entrainment and 汽蚀余量 issues). 水箱设计的科学并不是从一个立方体或一个旧的车载水箱开始或结束的——一个设计正确的水箱可以为你节省数千美元的水泵维护费用, 甚至拯救一条生命.
它们有多热?? 菠菜网最稳定正规平台_最全菠菜网大全的轴承设计在相对较高的温度下运行-我们设置的最高温度为120o C (248 o F). Possible reasons for bearings running hot logically include bearing failure; however, typically there will be other symptoms, such as unusual noise. 如果泥浆进入泵湿端密封，则在压盖失效后不久就会发生轴承失效.
It may simply be a faulty bearing. 上次维修时是否使用了原设备制造商的轴承? 这不是第一次价格高于价值导致低质量轴承被取代.
失败, or symptoms of failure, 也可能发生由于高皮带张力(传动端)或空气夹带或空化(湿端)。, which will ultimately damage the bearings. 确认温升(随时间升高或几乎立即升高)和最终温度. Look for other symptoms, such as noise. Ensuring personal safety, 用听音棒对着轴承座看是否有轴承运转不顺畅的迹象. Consult the factory with the range of symptoms.
幸运的是, 麦克菠菜网最稳定正规平台_最全菠菜网大全的轴承组件维修简单-购买轴承维修套件并按照说明操作. Be prepared with an oven for heating, 但组装不需要预加载设置-只需定位轴承到位, lubricate and put the end caps on, finish lubrication and you are done.
