作为各种高性能机电设备的供应商,我们对泵知之甚少。然而,这些有趣的事实也许会让我们惊叹不已......
As a supplier of a wide range of high-performance electro-mechanical equipment, we know a thing or two about pumps. However, even these interesting facts surprised us! Take a look for yourself…
1. 泵占世界电力消耗量的10%,如果更多的泵由变速驱动器控制,这个数字可以减少。
Pumps account for a massive 10% of the world’s electricity consumption, a figure which could be reduced if more pumps were controlled by variable-speed drives.
2. 以最佳效率运行的升级泵系统的投资回收期为一至五年。对于具有长期愿景的企业而言,这项投资是一项明确的决定。
An upgraded pump system running at optimal efficiency has a payback time of between one and five years. For businesses with a long-term vision, this investment’s a clear-cut decision.
3.欧洲电动机消耗的功率超过20%用于驱动泵。
Over 20% of the power consumed by electric motors in Europe is used to drive pumps.
4. 化学工业是泵的巨大用户,在德国进行的一项研究显示,该行业的每位员工平均有1.25台泵。
The chemical industry is a huge user of pumps, with a study in Germany revealing there are an average of 1.25 pumps for every employee in the sector.
5. 如果在全球范围内安装节能泵系统,全球用电量可减少4%。
If energy-efficient pumping systems were installed worldwide, global electricity consumption could be reduced by 4%.
很明显,低效泵系统对企业成本的影响远远超过升级或投资新设备的成本。
It’s clear that the serious financial implications of an inefficient pump system heavily outweigh the cost of an upgrade or investment in new equipment.

本期我们来认识机械泵
先看泵的分类
机械泵定义
机械泵是一种通过机械作用移动流体(液体或气体)的装置。泵可以根据它们运输流体的方式分为三大类:直接提升,排量和动力。
正排量泵
捕获固定量的流体并迫使(移动)该捕获的体积进入排放管或排放系统。 一些正排量泵在吸入侧使用扩展腔,在排出侧使用缩小腔。
正排量泵有两种类型:
1.旋转泵
2.往复泵
动力泵
动力泵有多种分类,其中两类是:离心式和轴向式。 这些泵通过高速的流体并在扩散流动通道中将速度转换成压力来实现操作。
动力泵有两种类型:
1.离心泵
2.特殊泵
