作為各種高性能機(jī)電設(shè)備的供應(yīng)商，我們對(duì)泵知之甚少。然而，這些有趣的事實(shí)也許會(huì)讓我們驚嘆不已......
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. 泵占世界電力消耗量的10％，如果更多的泵由變速驅(qū)動(dòng)器控制，這個(gè)數(shù)字可以減少。
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. 以最佳效率運(yùn)行的升級(jí)泵系統(tǒng)的投資回收期為一至五年。對(duì)于具有長(zhǎng)期愿景的企業(yè)而言，這項(xiàng)投資是一項(xiàng)明確的決定。
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.歐洲電動(dòng)機(jī)消耗的功率超過(guò)20％用于驅(qū)動(dòng)泵。
Over 20% of the power consumed by electric motors in Europe is used to drive pumps.
4. 化學(xué)工業(yè)是泵的巨大用戶，在德國(guó)進(jìn)行的一項(xiàng)研究顯示，該行業(yè)的每位員工平均有1.25臺(tái)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. 如果在全球范圍內(nèi)安裝節(jié)能泵系統(tǒng)，全球用電量可減少4％。
If energy-efficient pumping systems were installed worldwide, global electricity consumption could be reduced by 4%.
很明顯，低效泵系統(tǒng)對(duì)企業(yè)成本的影響遠(yuǎn)遠(yuǎn)超過(guò)升級(jí)或投資新設(shè)備的成本。
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.
正確認(rèn)識(shí)及選擇泵
熟知泵的性能
能夠提高運(yùn)行效率
本期我們來(lái)認(rèn)識(shí)機(jī)械泵
先看泵的分類
機(jī)械泵定義
機(jī)械泵是一種通過(guò)機(jī)械作用移動(dòng)流體（液體或氣體）的裝置。泵可以根據(jù)它們運(yùn)輸流體的方式分為三大類：直接提升，排量和動(dòng)力。
正排量泵
捕獲固定量的流體并迫使（移動(dòng)）該捕獲的體積進(jìn)入排放管或排放系統(tǒng)。 一些正排量泵在吸入側(cè)使用擴(kuò)展腔，在排出側(cè)使用縮小腔。
正排量泵有兩種類型：
1．旋轉(zhuǎn)泵
2.往復(fù)泵
動(dòng)力泵
動(dòng)力泵有多種分類，其中兩類是：離心式和軸向式。 這些泵通過(guò)高速的流體并在擴(kuò)散流動(dòng)通道中將速度轉(zhuǎn)換成壓力來(lái)實(shí)現(xiàn)操作。
動(dòng)力泵有兩種類型：
1.離心泵
2.特殊泵
