课程名称：探索泵的液压计算、操作与控制 概述：泵是任何工厂的核心设备，负责保证所需的工艺流量或压力。泵在石油、天然气、化工和石油化工行业中被广泛使用，用于在不同压力和温度下泵送各种流体。若没有泵或泵的运行出现问题，可能会导致过程扰动，严重时甚至会导致生产停滞。泵及其吸入口和排出口系统的选型是过程工程师在过程设计中主要的工作之一。本课程不仅将讲解泵在工艺中的操作理论，还将通过实际例子计算主要的泵要求，如净正吸入头（NPSH）、差压和液压功率。课程中将提供Excel表格，以指导你如何计算这些参数，您将在整个课程中访问泵计算表。 在本课程中，我们还将学习： - 泵曲线的工作原理及其与系统曲线的绘制。 - 泵与过程系统的相互作用，以及泵如何响应和影响过程变化或扰动。 - 离心泵与正位移泵的泵曲线之间的差异，以及它们各自如何与排放系统互动。 - 确保处于所需泵操作点的不同控制方法。 - 不同的泵配置，泵串联和并联的操作方式，以及这对泵曲线的影响。 期待在课程中见到您，希望这个课程能够为您带来新的价值！免责声明：请注意，Excel表格仅用于教育目的。如果您使用它来验证一个过程或购买设备或管道，您需要自行验证，使用它的风险自负。
Pumps have been the heart of any plant as they are the main equipment used to guarantee the required process flow or pressure. Pumps are used extensively in oil and gas, chemical, and petrochemical industries to pump different fluid types at various pressures and temperatures.Without a pump or if there is a problem in the pump operation, this can cause a huge process disturbance, and in some cases, this may lead to process shutdown.Sizing the pumps and their suction and discharge systems is one of the major carried-out activities by process engineers during process design. This course will not just explain the theory of operation of a pump against the process. We will see live examples where we shall calculate main pump requirements such as:Net positive suction head (NPSH)Differential headHydraulic powerThis will be through Excel sheets that will be provided in the course to teach you how to calculate these parameters. You shall have access to pump calculation sheets throughout the course.In this course, we shall also see:How the pump curve works and how to plot it against the system curve. How the pump and process system interact with each other and how the pump responds and interacts with process changes or disturbances. The difference between the pump curve of a centrifugal pump VS a positive displacement pump. We shall also see how each of them interacts with the discharge system differently.Different control methods to make sure we are on the required pump operating point. Different pump configurations, how to operate the pumps in series and in parallel, and how this is reflected on pump curves.So cannot wait to see you in the course, and I hope it shall give you added value!Disclaimer: Please note that the Excel sheets were made just for educational purposes. If you shall use it to validate a process or purchase equipment or piping, then you should validate it yourself, and using it shall be upon your sole responsibility.
