典型的料浆泵有液下有滑动轴承的结构和悬臂型两种。当输送介质为磷酸料浆时,其悬浮的二水石膏结晶(CaSo4?2H2o)含量可达30%左右。这时如仍采用上述结构,在腐蚀、磨蚀的双重作用下,对液下轴承的材料要求非常苛刻,许多合金和非金属材料都难以胜任。实践证明,磷酸料浆泵采用悬臂结构是一切实可行的解决办法。泵轴与电动同采用弹性联轴器相连接。泵的轴向力与径向力分别由轴承盒内的滚动轴承来承受。因下轴承的底板以上,可避免磷酸料浆泵或泡沫的腐蚀,这是国内外广为采用的
磷酸料浆泵中的一种较好的结构。 开箱检查
1.确认泵标牌上的型号、扬程、流量、转速、功率以及材料与订货合同单是否相同。
2.确知有无丢失的零件。
3.确定在运输过程中有无损伤螺栓及螺母有无松动。
4.用手转动泵轴,看转动是否匀调。如果转不动,或者感觉到有东西相碰,或不均衡就说明有故障。
料浆泵的安装
1.料浆泵一般安装于低位槽上,应单独设立牢固的型钢支架或钢筋混凝土框架,{zh0}不要与低位槽连在一起。泵架应有足够的强度和刚度。
2.校正联轴器的中心线,使电机轴与泵轴保持同心。
3.泵轴的中心线应与水平垂直、可用普通铁水平尺在经过机械加工的与中心垂直的水平面上检查。并用垫片调整底板的位置至符合要求。
4.泵的吸入口距容器底部不得少于100mm,四周不应少于200mm。
5.出液管不承受外加载荷,连接管线须另设支承固定。
6.在安装管线时,容易有木片、螺栓、螺母、铁器、石块、破布等异物进入管内,要特别注意xx。此外槽体内部也应全部清扫干净。

原文:
A typical slurry pump with liquid sliding bearings under the two
kinds of structures and cantilever. When the transmission medium is
phosphoric acid slurry, its suspension gypsum crystals (CaSo4?
2H2o) content of up to 30% or so. Then if still using the
above-mentioned structure, corrosion, erosion of the dual role, the
right liquid bearing material requires very harsh, and many alloys
and non-metallic materials could not do both. Practice has proven
that phosphoric acid slurry pump with cantilevered structure is a
practical solution. Pump shaft and electric connected with the
adoption of a flexible coupling. Pump axial force and radial force
by the rolling bearing box to bear. Under the floor due to bearing
more than can be avoided or foam phosphate slurry pump corrosion,
which is widely used at home and abroad phosphate slurry pump in a
better structure.
Check box
1. Sure signs on the pump model, head, flow, speed, power and
material order contract with a single are the same.
2. To ascertain whether the missing parts.
3. To determine whether the damage during transport, whether or
loose bolts and nuts.
4. Rotating pump shaft by hand to see whether the uniform rotation
adjustment. If we can not move, or felt something touching, or do
not balance on the note could be faulty.
The installation of slurry pump
1. Slurry pump usually installed in the low slot, we should set up
a separate solid steel frames or reinforced concrete frame, it is
best not to together with the low slot. Pump frame should have
sufficient strength and stiffness.
2. Correction coupling centerline, the motor shaft and pump shaft
to maintain concentricity.
3. Shaft's center line should be horizontal and vertical, can be
used after normal iron level scale machining center vertical and
horizontal surface inspection. And use pads to adjust the location
of floor to meet the requirement.
4. Pump suction from the bottom of the vessel shall not be less
than 100mm, surrounded by not less than 200mm.
5. Out of drain pipe does not bear external loads, the connection
pipe to separate the fixed bearing.
6. In installing pipeline, it is easy with wood, bolts, nuts, iron,
stones, rags and other foreign matter into the tube, should pay
special attention to remove. In addition, all the tank should be
cleaned inside.
