My columns to date Split case pumps have generally assumed a knowledge of basic pump terminology by the readers. However, I am beginning to realize that not every pump user possesses Split case pumps this rudimentary understanding of pumps. This column describes two very basic, similar and useful centrifugal pump hydraulic characteristics. They are “Specific Speed” and “Suction Specific Speed”. While Specific Speed refers to the discharge characteristics of In-line pumps a pump, Suction Specific Speed, as the name implies, refers to the suction characteristics. In should be noted that the values of both of these terms remain constant for a given pump, regardless of the speed of the pump.

我列迄今为止所承担的一般读者泵术语的基本知识。不过，我开始意识到，并不是每个用户拥有这种泵泵起码的了解。本专栏介绍了两个非常基本的，类似的和有益的离心泵水力特性。它们是“具体的速度”和“吸比转速”。虽然比转速是指水泵，吸比转速的放电特性，顾名思义，指的是吸力特性。在应该指出，这些方面均保持不变的值为给定的泵，不论泵的速度。
