使用變頻器注意事項:
1:水泵轉速調節范圍不宜太大,通常不低于額定轉速的50%,當轉速低于50%水泵本身效率明顯下降。在調頻時應避開泵機組的機械共振效率,否則將損壞泵機組。
2、當電動機由變頻切換至工頻電網運行時,必須延時5s以上進行定速運行后接觸器才自動合閘,以防操作過電壓。
3、當電動機由工頻電網切換至變頻變頻器供電運行時,必須延時10s后接觸器再閉合,以防止電動機高速產生感應電勢損壞電子器件。
4:變頻器使用環境溫度不應太高,特別是*運行的水泵,可能損壞功率模塊。
使用變頻器的優點:
1:能夠節省大量的電能,在使用變頻器之前,泵類只能靠閥門來控制流量,而使用變頻器后可以通過調整頻率可以改變泵的轉速,達到了改變流量的目的,同時使用變頻器可以使生產設備處于*狀態下運行,減小了氨水對閥門、管道的磨損。一般使電機轉速在額定轉速下。
2:延長了電動機的使用壽命,由于三相異步電動機的起步電流為額定電流的5—7倍,對電機壽命有很大的損傷。而變頻器的啟動時候一種軟啟動發式,保護了泵電機。
3:大大減輕操作人員的勞動強度,原來控制氨水流量只能靠倒閥來控制氨水流量,現在自動變頻情況下可以通過現場壓力—流量傳感器反饋的信號自動調節,在手動情況下,也只需調節面板上的電位器來改變電機頻率,方便易行。

4:減輕對電網諧波干擾,變頻器反饋到電網的諧波是由無功功率,換流能量,諧波電流組成,使用變頻器能使反饋到電網的諧波分量限制在允許的幅值范圍內。
5:使用變頻器后對電機有了可靠的保護,如過流、過壓、欠壓、缺相等保護。
