菠菜网最稳定正规平台_最全菠菜网大全的M3H系列泵是根据50多年的泵经验开发的，具有以前型号的扬程和效率改进. 此范围的卧式主轴, abrasion/corrosion resistant centrifugal 泥浆泵 is designed for construction sands, 压裂砂, 玻璃砂, 硅砂, 矿物砂, 水处理设施等.
泥浆泵的工作原理
Using the conversion of rotational kinetic energy into the hydrodynamic energy of the fluid flow, 离心浆泵激发流体沿管道流动. 泵旋转, 因此转动能, is typically created by the electric motor driving the Pump shaft through a V-belt drive. 流体沿轴向进入泵叶轮眼内, 通过它的旋转切向和径向作用于流体. The fluid is accelerated by the impeller gaining velocity and pressure, 径向向外流入套管的, 减速，但压力在增加. 被加压后，它就离开了蜗壳. 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, 把它推到叶轮里.
The speed of the Pump is regulated by the ratio of the transmission plus, 在某些情况下, the use of a variable frequency drive to tune the speed for a more exact duty. Care needs to be taken not to use high turn-down ratios, which result in the loss of power. 头部或更具体地说，总动态头部, 哪个是静力之和, 摩擦和压头, 是用来找速度头的吗. 对计算水头进行了修正(HR) using the d50 of the particles being pumped, the percent solids by volume. Horsepower is calculated as work done and thus includes the fluid specific gravity. 应始终参考制造商的曲线，以确保泵在最有效的区域运行.
需要注意的是，这种泵的设计, 不像自吸容积泵, 不会把液体吸进套管. 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] +污水池与水位的高度).
其他因素影响泵的性能, 其中最重要的是净正吸头(汽蚀余量), 这不仅是设备问题，还是系统问题. 汽蚀余量A 是一种测量流体接近蒸汽压的方法吗. 汽蚀余量R is head value on the suction side that is required to keep the fluid from cavitating. 加热后的溶液特别容易发生. Significant damage can occur to the impeller and bearings when a Pump is cavitating.
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. Examples of this are in 尾矿 disposal down long inclines to ponds. 需要特殊的构建.
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. Gravel should be handled by hard metal Pumps, such as Ni-Hard or Hi-Chrome (27%).
为什么选用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 feature a split casing design to allow easy access to the liners, 对叶轮和压盖进行维护. 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 feature field replaceable wet-end liners to facilitate an ease of maintenance. 这些衬垫是自密封的，提供可靠的密封. 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's bearing assembly is exceptionally simple but nonetheless long-lasting. 与其他制造商不同, the bearing housing reassembly process requires no preload setup given the wet-end, 重型滚子轴承和驱动端, 双, 调心, 球面滚子轴承. 按安装要求将部件装入外壳, 操作维护手册, 按照指示润滑，你就可以出发了. Factory rebuilt bearing assemblies are available for the most urgent of maintenance.
泥浆泵压盖的类型
菠菜网最稳定正规平台_最全菠菜网大全泥浆泵提供三种类型的压盖:
- d型 glands are our most fitted gland and feature a rotating rubber seal ring and a static ceramic face. 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. 对于粘性较大的浆料，不建议采用这种设计.
- 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/小时(20-25千帕以上). 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. The outer seal is adjusted to allow gland water to seep out for lubrication, while the water at the internal seal flushes solids away from the seal. 这种压盖非常适合稠化剂底流等应用.
- p型 glands are the classic design and are the most common in the industry. Specialized packing rings are wrapped around the gland sleeve and compressed to make a seal. 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. 清洁的水对这个腺体至关重要, 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.
Each of these glands is designed to seal the pressurized wet end of the Pump from the atmosphere. 所有的压盖都有一个压盖套筒，以保护轴不受磨损. Seals and components are manufactured from abrasion/corrosion resistant materials.
泥浆泵叶轮的类型
菠菜网最稳定正规平台_最全菠菜网大全 offers two designs of impellers: closed vane and open vane.
封闭的叶片 叶轮由高质量橡胶模压在钢骨架上. 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. Typical open impellers allow significant bypass as they wear, and efficiency reduces dramatically.
开放的叶片 叶轮不是嵌入式叶轮式泵. 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. 开放的叶片 is the choice for solid and fibrous material with a minimal risk of clogging, such as in agricultural applications separating manure from bedding sand.
关于浆泵的常见问题
向专家请教除了通常的旋转部件的保护, 从制造商或经销商那里得到建议是很重要的. 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, it may not pump anywhere close to that if the duty isn’t the same as the original. 每个职责都很具体. 假设您安装了泵，但管道的尺寸不对, 你可能会在处理材料上遇到严重的问题, 甚至可能导致泵爆炸.
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. If a condition occurs that blocks the inlet pipe and outlet pipe of the 泥浆泵, 据估计，电机40%的能量将用于加热泵的湿端内容物. The heat rise can be rapid and steam pressure will build, and an explosion can occur. 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’s recently developed thermocouple device is another safety feature when fitted and alarmed.
良好的工艺设计, 正确的污水池和管道机械设计, and use of safety related add-ons are factors determining the safe operation of a Pump. 制造商永远是最好的起点.
Because the Pump is running at fixed speed and hasn’t been told that you removed a section of pipe, 它将继续旋转，但现在发现它更容易抽水. 如果你看泵曲线, you will see that if you lower the head (resistance) that the Pump is pumping against, 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. The higher flowrate means more work is being done and thus power demand is greater. 如果降低泵送的高度也是一样的. 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. The danger with increasing the head without changing the speed is the lower flowrate that results, 哪个可能低于临界凝固速度. Contact the manufacturer if you are contemplating changes to any part of your pump system.
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
而不是直接说不, 任何泵制造商的第一反应是什么, 让我们来看看为什么你可能不想考虑这个问题. From our perspective, 90% of problems are on the suction side of a Pump. 这些问题, 其中90%与糟糕的污水池设计有关, 例如错误的墙角(在山谷角和角落积聚), 太浅(漩涡), 太大(沉降和脱落), (带气性)太小, 涡旋)和不正确的吸入线(夹带和汽蚀余量问题). 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’s bearings are designed to run at a relatively high temperature — we set a maximum of 120o C (248 o F). Possible reasons for bearings running hot logically include bearing failure; however, 通常还会有其他症状, 比如不寻常的噪音. 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.
可能只是轴承有毛病. Were original equipment manufacturer bearings used during the last repair? 这不是第一次价格高于价值导致低质量轴承被取代.
失败, 或者是失败的症状, can also occur due to high belt tension (drive end) or air entrainment or cavitation (wet end), 哪一个最终会损坏轴承. Confirm the temperature rise (rises over time or almost immediate) and ultimate temperature. 寻找其他症状，比如噪音. 确保人身安全, use a listening stick against the housing for signs that the bearings are not running smoothly. 向工厂咨询症状范围.
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. 准备好烤箱加热, but the assembly requires no preload settings — just locate the bearings in place, 润滑并盖上端盖, 完成润滑，你就完成了.
