砂浆泵A余干砂浆泵常见问题
However, its toughness is poor, can not withstand the rapid impact of large solid particles, if not, will cause the impeller surface material shedding, the section is prone to corrosion and the formation of pits, wear-resistant rubber materials wear resistance, corrosion resistance are better than metal materials, elasticity, but only suitable for conveying fine granular slurry without angle. Therefore, the choice of slurry pump lining, according to the type of ore to make a reasonable choice, so as to improve the utilization rate of the pump. General users in the slurry pump selection, only pay attention to the pump flow selection, ignoring the pump lift selection, some people even think that the higher the head more insurance, so the choice of slurry pump head to be greater than the actual lift demand, and so much waste of electricity. The selection of slurry pump should be selected according to the actual lift demand, in order to reduce the number of installed machines and se electricity. In addition, it is important to note that in the calculation of the lift, it is necessary to consider the loss of the head, to oid the pump lift is not enough, and affect the pump drainage efficiency. Motor and slurry pump power is not reasonable matching.
渣浆泵工作原理
X先讲述一下离心泵和渣浆泵的关系，然后渣浆泵原理也就自然清晰了。离心概念是从泵原来来讲的。泵有许多种，依据不同的角度可划分几十个类别。离心泵是从泵的工作原理上划分，是通过离心力作用来达到给输送介质增压的。另外还有常见的种类包括螺杆原理，柱塞原理等可以划分出不同于离心原理的泵。说完离心泵概念，再说渣浆泵，渣浆泵又是从另外一个角度来划分泵的，即从输送介质来划分的。顾名思义，渣浆泵输送的是含有渣滓的固体颗粒与水的混合物。但从原理上讲渣浆泵属于离心泵的一种。这样这两个概念就讲清楚了。wjhuiquan4.15

In some cases, the service life of the front guard of the slurry pump is less than half that of this value, and even the fracture of the front guard plate will occur. Introduction of castings the front guard plate belongs to an overcurrent part of the slurry pump, which is impacted by the fluid during operation, and the main force part is in the outlet position. The production of slurry pump front guard plate maximum diameter of 900mm, the total height of 250mm, outlet wall thickness of 30mm, outlet below the maximum thickness of the guard plate is 50mm. The material of the impeller is high chromium cast iron, the technical requirements of the product are more strict, no riser defects are allowed, and the hardness after heat treatment is >58HRC. 1) Modeling equipment using 10t/h continuous sand mixing machine, alkali phenolic resin sand modeling. 2) The fractal surface is selected in the middle part of the guard plate, the shape is divided into molds, made into a shaped bottom plate, the wide size of the 1200mmx1200mm. (3) The material is KmTBCr26, the casting line shrinkage rate takes 2%, the open pouring system. Depending on the size and shape of the casting.
离心泵的主要工作部件是叶轮和机壳，机壳内的叶轮装置位于轴上，并与原动机连接形成一个整体。当原动机机带动叶轮时，叶轮中的叶片迫使流体，即叶片对流体沿它的运动方向做功，从而迫使流体的压力势能和动能。与此同时，流体在惯的作用下，从中心向叶轮边缘流去，并以很高的的速度叶轮，压出室，再经扩散管，这个称为压水。同时，由于叶轮中心的流体流向边缘，在叶轮中心形成低压区，当它具有足够的真空时，在端压强的作用下（一般是大气压强），流体经室叶轮，这个称为吸水。由于叶轮连续的，流体也就连续的、，形成连续的工作。
离心式的泵（包括渣浆泵）的工作，实际上是一个能量传递和转化的。它将电动机高速的机械能，通过泵的叶片传递并转化为被抽升流体的压能和动能。
AH型M型HH型分数渣浆泵用途
渣浆泵可广泛用于矿山，电力、冶金、环保等行业输送含有磨蚀性固体颗粒的浆体。如冶金选矿厂矿浆输送，火电厂水力除灰、洗煤厂煤浆及重介输送，疏浚河道，河流清淤等。在化工产业，也可输送一些含有结晶的腐蚀性浆体。
X先，在选矿厂的应用，80%左右都是用在矿山行业选矿厂。由于矿石初选工况较为恶劣，因此在这一工段，渣浆泵的使用寿命普遍较低。当然，不同的矿石，磨蚀性也不一样。如在精矿输送等工段相对磨蚀性减小，泵的整体使用寿命也就较长。所以一般用户在采购中经常问到供应商的产品的使用寿命问题时候，严格讲任何一家生产商等都不会毫无根据的为用户承诺一个准确使用寿命周期，因为过流部件的使用寿命（耐磨耐腐蚀件）的寿命取决于多种不同因素，工况的的多样性和复杂性同样品质的材质的使用寿命是有差异的。但是在前期选型阶段可以让有实力的生产厂家为其做合理工况选型设计。
其次，在电力行业，主要是火力发电厂。目前我国电厂中主要是火力发电和水利发电，在火电厂中，由于用大量燃煤发电，燃煤后的炉渣或者灰渣需要，渣浆泵被用在除灰渣的作用，炉渣通过混合一定量的水后，通过渣浆泵将其输送到灰渣堆放的地方，因此有时渣浆泵在电厂也成为灰渣泵。
再次，在洗煤行业，由于工况不同，较大煤块，煤矸石容易堵塞，对于渣浆泵的设计要求很高。淮北矿务局下属某洗煤厂05年采用经特殊设计的、替代原来从澳大利亚进口的渣浆泵，至今运转正常，无堵塞，使用磨损寿命X过了国外进口泵。
在海水选砂X域，渣浆泵应用也开始逐渐被客户认可。但是在海水里选砂，河道里挖沙，渣浆泵更容易被称为砂泵，挖泥泵。尽管叫法不一，但是从结构特点和泵的性能原理上来讲，都可以通称为渣浆泵。因此在这海水选砂中我们经常称为砂泵，在河道清淤里面习惯上叫挖泥泵。

If the cutting heat produced in the cutting process is not high, and the impeller surface layer does not produce thermoplastic deformation, in this case is mainly cold plastic deformation, then the surface layer will produce residual comdivssive stress. When the cutting heat is higher and even the thermoplastic deformation is produced in the surface layer of the slurry pump impeller, then the comdivssive stress caused by the thermal plastic deformation and the cold plastic deformation will offset part of each other, if the cold plastic deformation occupies the dominant position. May play a leading role in one or both of these reasons under certain conditions of course AH slurry pump is mainly from the divvious three aspects of the comdivhensive effect of the results of the slurry pump impeller surface layer after mechanical processing produced a complex residual stress slurry pump impeller surface layer will produce residual tensile stress. In grinding generally due to high grinding heat, often with metallographic deformation and thermal plastic deformation caused by tensile stress, therefore, the surface layer of the slurry pump impeller often with residual tensile stress.
渣浆泵的用途虽然广泛，但是正确的应用是十分重要的。渣浆泵由于其名称本身的局限性使得一些非本行业的人对此产生误解，事实上，泥浆泵，杂质泵，挖泥泵，清淤泵，等都在渣浆泵的应用范围。在渣浆泵的应用中，一定要注意合理的设计，正确的计算，的选型，这几点非常重要。
