ITT Flygt與ABB合作研發(fā)出一系列VFD產(chǎn)品，這些產(chǎn)品獨(dú)有的Flygt軟件是專門(mén)為污水泵而設(shè)計(jì)的。一般的VFD必須經(jīng)過(guò)人工手動(dòng)設(shè)置大量的參數(shù)才可以適用于多種不同設(shè)備。然而當(dāng)您應(yīng)用ACS550.這種新版本時(shí)，就會(huì)省去了上面諸多的步驟。使用Flygt的VFD優(yōu)點(diǎn)：
●提高系統(tǒng)可靠性，降低重電機(jī)及液壓系統(tǒng)的承載量；
●改善對(duì)于生產(chǎn)過(guò)程的控制，使流量和賽制匹配為系統(tǒng)的需求；
●在新建和改造優(yōu)化標(biāo)注設(shè)施時(shí)獲得更大的靈活性；
●按照系統(tǒng)需求來(lái)調(diào)節(jié)泵的速度以期更加節(jié)省能源。
ACS550提供了一個(gè)特別程序以減少堵塞的危險(xiǎn)，幫助葉輪保持清潔。通過(guò)一個(gè)預(yù)先的設(shè)置，操作人員可以減少環(huán)境參數(shù)的設(shè)置高達(dá)90%以上。當(dāng)ACS550檢測(cè)到一個(gè)超負(fù)荷值高于預(yù)設(shè)值時(shí),它會(huì)引動(dòng)順序清洗程序。這不僅能提高設(shè)備的可靠性，同時(shí)也意味著較少的緊急叫停。ACS550可以與其他的控制器例如Flygt的FMC配合應(yīng)用，可以匹配不同的SCADA系統(tǒng)接口，包括Flygt的aquaview。
New Range of VFDs Tailored for Wastewater Pumps
In co-operation with ABB, ITT Flygt has developed a range of VFDs which, with their unique Flygt software, are specifically tailored for wastewater pumps.
A standard VFD can be used in many different applications. But before it can be taken into use a large number of parameters have to be set manually. However, this is not needed when using this new version of ACS550.
The advantages of using a Flygt VFD:
Boost system reliability – reduce stresses on electrical and hydraulic systems.
Improve process control – match flow and head to system requirements.
Gain greater flexibility – optimize dimensioning in new and retrofit installations.
Save energy – adjust pump speed to system demand.
To reduce the risk of clogging the ACS550 is supplied with a special program that has been developed to help keep impellers clean. A selection of pre-settings reduce the number of parameters needed to be handled by more than 90 percent. When the ACS550 senses an increase in load that exceeds a preset value, it triggers a cleaning sequence. Not only does this improve reliability, but it also means fewer emergency call-outs. The ACS550 can communicate with other pump controllers such as Flygt’s FMC and can interface with different SCADA systems, including Flygt’s AquaView.
