本文主要讲的是压力增压泵,什么是增压系统?增压系统采用一个或多个增压泵(离心泵的一种)来增加水系统中的低压,使水达到足够的流量和压力给用户。增压系统本身是由一个或多个泵组成的,安装这些泵是为了增加系统内的压力,使之与流量和进口压力无关。增压系统本身有许多系统配置。不同的配置具有不同的优势和特点,如舒适性、初始投资成本、运行成本、灵活性和供应。本篇美国作业代写文章由美国论文通AssignmentPass辅导网整理,供大家参考阅读。

What is a pressure boosting system? A pressure boosting system employs one or more boosting pumps, a type of centrifugal pump, to increase low pressure in a water system where it will reach sufficient water flow and pressure to consumers. The pressure boosting system itself is made up of one or more pumps which are installed to increase the pressure in the system to a point where it is independent of flow and inlet pressure. The pressure boosting system itself has many system configurations. Different configurations have different advantages and characteristics such as comfort level, initial investment cost, running costs, flexibility and supply.
For this project we also decided to use the VFD to control the pressure boosting pumps. The VFD controlled systems is able to deliver the exact amount of water which will make the pump very efficient. The VFD systems set point can also be altered according to the flow of the water which will reduce energy loss the reduced pipe resistance. The initial investment of the VFD pressure boosting pump will be higher than a normal pressure boosting pump. However, the running cost will be lower, the comfort level will be very good, and the flexibility of the system is much better. In conclusion, we believe that the VFD pressure boosting pump will be overall better than the standard normal pressure pump in the long run.
