The characteristics of Horizontal single-stage pump: pump should be installed in the ventilation and anti freezing place; the installation of the pump to ensure the tension of the pump will not be influenced by the pipeline system; electrical wiring device shall ensure that the pump is not affected by the lack of phase, voltage instability, leakage and overload; pump should be installed horizontally on the base the horizontal direction, the suction port of the pump, vertical pump outlet.
立式单级泵的特点：高温型应先进行预热，升温速度50℃/小时，以保证各部受热均匀；用手盘动泵以使润滑液进入机械密封端面；打开排气阀使液体充满整个泵体，待满后关闭排气阀。
The characteristics of vertical single stage pump: high temperature should be preheated, the heating rate of 50 DEG / h, to ensure the uniform heating; in order to make the lubricating fluid into the mechanical seal with the hand disc pump; open the exhaust valve so that the liquid fill the pump, close the exhaust valve to be filled.
一般典型的卧式单级泵是IS型、IR型、IY型等，立式单级泵是ISG型为代表。
Generally the typical Horizontal single-stage pump is IS type, IR type, IY type and so on, the vertical single stage pump is the ISG type as the representative.
按吸入的流道可分为：单级单吸离心泵，单级双吸离心泵。单级单吸离心泵就是IS型为代表，单级双吸离心泵是以S型为代表。
According to the suction flow channel can be divided into: single-stage single suction centrifugal pump, single stage double suction centrifugal pump. Single-stage single suction centrifugal pump is represented by the IS type, single stage double suction centrifugal pump is represented by the S type.
我们都知道离心泵的种类繁多，单级泵也是其中的一种。同时单级泵按不同的结构，不同的安装位置也有不同的种类。通过以上分析我们可以知道，单级泵可以分为卧式单级泵和立式单级泵。所以对于消费者而言，在选择产品是需要对产品有一定了解，不然不仅耽误生产时间，也耗费人力物力。
We all know that there are many kinds of centrifugal pump, single stage pump is one of them. At the same time, the single pump according to different structures, different installation positions also have different types. Through the above analysis, we can know that the single-stage pump can be divided into Horizontal single-stage pump and vertical single-stage pump. So for consumers, in the choice of products is the need to have a certain understanding of the product, or not only delay the production time, but also the cost of human resources.
